And then instead of passing the object from the database as a parameter to the background task function, you would pass the ID of that object and then obtain the object again inside the background task function. + +The sequence of execution before FastAPI 0.106.0 was like this diagram: + +Time flows from top to bottom. And each column is one of the parts interacting or executing code. + +```mermaid +sequenceDiagram + +participant client as Client +participant handler as Exception handler +participant dep as Dep with yield +participant operation as Path Operation +participant tasks as Background tasks + + Note over client,tasks: Can raise exception for dependency, handled after response is sent + Note over client,operation: Can raise HTTPException and can change the response + client ->> dep: Start request + Note over dep: Run code up to yield + opt raise + dep -->> handler: Raise HTTPException + handler -->> client: HTTP error response + dep -->> dep: Raise other exception + end + dep ->> operation: Run dependency, e.g. DB session + opt raise + operation -->> dep: Raise HTTPException + dep -->> handler: Auto forward exception + handler -->> client: HTTP error response + operation -->> dep: Raise other exception + dep -->> handler: Auto forward exception + end + operation ->> client: Return response to client + Note over client,operation: Response is already sent, can't change it anymore + opt Tasks + operation -->> tasks: Send background tasks + end + opt Raise other exception + tasks -->> dep: Raise other exception + end + Note over dep: After yield + opt Handle other exception + dep -->> dep: Handle exception, can't change response. E.g. close DB session. + end +``` + +The new execution flow can be found in the docs: [Execution of dependencies with `yield`](https://fastapi.tiangolo.com/tutorial/dependencies/dependencies-with-yield/#execution-of-dependencies-with-yield). + +### Features + +* ✨ Add support for raising exceptions (including `HTTPException`) in dependencies with `yield` in the exit code, do not support them in background tasks.

Ed è stato ideato per essere la **FastAPI delle CLI**. ⌨️ 🚀 + +## Requisiti + +Python 3.6+ + +FastAPI è basata su importanti librerie: + +* Starlette per le parti web. +* Pydantic per le parti dei dati. + +## Installazione + +
+ +```console +$ pip install fastapi + +---> 100% +``` + +
+ +Per il rilascio in produzione, sarà necessario un server ASGI come Uvicorn oppure Hypercorn. + +
+ +```console +$ pip install uvicorn[standard] + +---> 100% +``` + +
+ +## Esempio + +### Crea un file + +* Crea un file `main.py` con: + +```Python +from fastapi import FastAPI +from typing import Optional + +app = FastAPI() + + +@app.get("/") +def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +def read_item(item_id: int, q: str = Optional[None]): + return {"item_id": item_id, "q": q} +``` + +
+Oppure usa async def... + +Se il tuo codice usa `async` / `await`, allora usa `async def`: + +```Python hl_lines="7 12" +from fastapi import FastAPI +from typing import Optional + +app = FastAPI() + + +@app.get("/") +async def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +async def read_item(item_id: int, q: Optional[str] = None): + return {"item_id": item_id, "q": q} +``` + +**Nota**: + +e vuoi approfondire, consulta la sezione _"In a hurry?"_ su `async` e `await` nella documentazione. + +
+ +### Esegui il server + +Puoi far partire il server così: + +
+ +```console +$ uvicorn main:app --reload + +INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit) +INFO: Started reloader process [28720] +INFO: Started server process [28722] +INFO: Waiting for application startup. +INFO: Application startup complete. +``` + +
+ +
+Informazioni sul comando uvicorn main:app --reload... + +Vediamo il comando `uvicorn main:app` in dettaglio: + +* `main`: il file `main.py` (il "modulo" Python). +* `app`: l'oggetto creato dentro `main.py` con la riga di codice `app = FastAPI()`. +* `--reload`: ricarica il server se vengono rilevati cambiamenti del codice. Usalo solo durante la fase di sviluppo. + +

tip + もし急いでいたり、HTTPSの仕組みについて気にしないのであれば、次のセクションに進み、さまざまなテクニックを使ってすべてをセットアップするステップ・バイ・ステップの手順をご覧ください。 + +利用者の視点から **HTTPS の基本を学ぶ**に当たっては、次のリソースをオススメします: https://howhttps.works/. + +さて、**開発者の視点**から、HTTPSについて考える際に念頭に置くべきことをいくつかみていきましょう: + +* HTTPSの場合、**サーバ**は**第三者**によって生成された**「証明書」を持つ**必要があります。 + * これらの証明書は「生成」されたものではなく、実際には第三者から**取得**されたものです。 +* 証明書には**有効期限**があります。 + * つまりいずれ失効します。 + * そのため**更新**をし、第三者から**再度取得**する必要があります。 +* 接続の暗号化は**TCPレベル**で行われます。 + * それは**HTTPの1つ下**のレイヤーです。 + * つまり、**証明書と暗号化**の処理は、**HTTPの前**に行われます。 +* **TCPは "ドメイン "について知りません**。IPアドレスについてのみ知っています。 + * 要求された**特定のドメイン**に関する情報は、**HTTPデータ**に入ります。 +* **HTTPS証明書**は、**特定のドメイン**を「証明」しますが、プロトコルと暗号化はTCPレベルで行われ、どのドメインが扱われているかを**知る前**に行われます。 +* **デフォルトでは**、**IPアドレスごとに1つのHTTPS証明書**しか持てないことになります。 + * これは、サーバーの規模やアプリケーションの規模に寄りません。 + * しかし、これには**解決策**があります。 +* **TLS**プロトコル(HTTPの前に、TCPレベルで暗号化を処理するもの)には、**SNI**と呼ばれる**拡張**があります。 + * このSNI拡張機能により、1つのサーバー(**単一のIPアドレス**を持つ)が**複数のHTTPS証明書**を持ち、**複数のHTTPSドメイン/アプリケーション**にサービスを提供できるようになります。 + * これが機能するためには、**パブリックIPアドレス**でリッスンしている、サーバー上で動作している**単一の**コンポーネント(プログラム)が、サーバー内の**すべてのHTTPS証明書**を持っている必要があります。 + +* セキュアな接続を取得した**後**でも、通信プロトコルは**HTTPのまま**です。 + * コンテンツは**HTTPプロトコル**で送信されているにもかかわらず、**暗号化**されています。 + + +サーバー(マシン、ホストなど)上で**1つのプログラム/HTTPサーバー**を実行させ、**HTTPSに関する全てのこと**を管理するのが一般的です。 + +**暗号化された HTTPS リクエスト** を受信し、**復号化された HTTP リクエスト** を同じサーバーで実行されている実際の HTTP アプリケーション(この場合は **FastAPI** アプリケーション)に送信し、アプリケーションから **HTTP レスポンス** を受け取り、適切な **HTTPS 証明書** を使用して **暗号化** し、そして**HTTPS** を使用してクライアントに送り返します。 + +このサーバーはしばしば **TLS Termination Proxy**と呼ばれます。 + +TLS Termination Proxyとして使えるオプションには、以下のようなものがあります: + +* Traefik(証明書の更新も対応) +* Caddy (証明書の更新も対応) +* Nginx +* HAProxy + + +## Let's Encrypt + +Let's Encrypt以前は、これらの**HTTPS証明書**は信頼できる第三者によって販売されていました。 + +これらの証明書を取得するための手続きは面倒で、かなりの書類を必要とし、証明書はかなり高価なものでした。 + +しかしその後、**Let's Encrypt** が作られました。 + +これはLinux Foundationのプロジェクトから生まれたものです。 自動化された方法で、**HTTPS証明書を無料で**提供します。これらの証明書は、すべての標準的な暗号化セキュリティを使用し、また短命(約3ヶ月)ですが、こういった寿命の短さによって、**セキュリティは実際に優れています**。 + +ドメインは安全に検証され、証明書は自動的に生成されます。また、証明書の更新も自動化されます。 + +このアイデアは、これらの証明書の取得と更新を自動化することで、**安全なHTTPSを、無料で、永遠に**利用できるようにすることです。 + +## 開発者のための HTTPS + +ここでは、HTTPS APIがどのように見えるかの例を、主に開発者にとって重要なアイデアに注意を払いながら、ステップ・バイ・ステップで説明します。 + +### ドメイン名 + +ステップの初めは、**ドメイン名**を**取得すること**から始まるでしょう。その後、DNSサーバー(おそらく同じクラウドプロバイダー)に設定します。 + +おそらくクラウドサーバー(仮想マシン)かそれに類するものを手に入れ、固定の **パブリックIPアドレス**を持つことになるでしょう。 + +DNSサーバーでは、**取得したドメイン**をあなたのサーバーのパプリック**IPアドレス**に向けるレコード(「`Aレコード`」)を設定します。 + +これはおそらく、最初の1回だけあり、すべてをセットアップするときに行うでしょう。 + +!!! tip + ドメイン名の話はHTTPSに関する話のはるか前にありますが、すべてがドメインとIPアドレスに依存するため、ここで言及する価値があります。 + +### DNS + +では、実際のHTTPSの部分に注目してみよう。 + +まず、ブラウザは**DNSサーバー**に**ドメインに対するIP**が何であるかを確認します。今回は、`someapp.example.com`とします。 + +DNSサーバーは、ブラウザに特定の**IPアドレス**を使用するように指示します。このIPアドレスは、DNSサーバーで設定した、あなたのサーバーが使用するパブリックIPアドレスになります。 + + + +### TLS Handshake の開始 + +ブラウザはIPアドレスと**ポート443**(HTTPSポート)で通信します。 + +通信の最初の部分は、クライアントとサーバー間の接続を確立し、使用する暗号鍵などを決めるだけです。 + + + +TLS接続を確立するためのクライアントとサーバー間のこのやりとりは、**TLSハンドシェイク**と呼ばれます。 + +### SNI拡張機能付きのTLS + +サーバー内の**1つのプロセス**だけが、特定 の**IPアドレス**の特定の**ポート** で待ち受けることができます。 + +同じIPアドレスの他のポートで他のプロセスがリッスンしている可能性もありますが、IPアドレスとポートの組み合わせごとに1つだけです。 + +TLS(HTTPS)はデフォルトで`443`という特定のポートを使用する。つまり、これが必要なポートです。 + +このポートをリッスンできるのは1つのプロセスだけなので、これを実行するプロセスは**TLS Termination Proxy**となります。 + +TLS Termination Proxyは、1つ以上の**TLS証明書**(HTTPS証明書)にアクセスできます。 + +前述した**SNI拡張機能**を使用して、TLS Termination Proxy は、利用可能なTLS (HTTPS)証明書のどれを接続先として使用すべきかをチェックし、クライアントが期待するドメインに一致するものを使用します。 + +今回は、`someapp.example.com`の証明書を使うことになります。 + + + +クライアントは、そのTLS証明書を生成したエンティティ(この場合はLet's Encryptですが、これについては後述します)をすでに**信頼**しているため、その証明書が有効であることを**検証**することができます。 + +次に証明書を使用して、クライアントとTLS Termination Proxy は、 **TCP通信**の残りを**どのように暗号化するかを決定**します。これで**TLSハンドシェイク**の部分が完了します。 + +この後、クライアントとサーバーは**暗号化されたTCP接続**を持ちます。そして、その接続を使って実際の**HTTP通信**を開始することができます。 + +これが**HTTPS**であり、純粋な(暗号化されていない)TCP接続ではなく、**セキュアなTLS接続**の中に**HTTP**があるだけです。 + +!!!

+ +각 옵션이 무엇을 의미하는지 살펴봅시다: + +* 이것은 유비콘과 똑같은 문법입니다. `main`은 파이썬 모듈 네임 "`main`"을 의미하므로 `main.py`파일을 뜻합니다. 그리고 `app`은 **FastAPI** 어플리케이션이 들어 있는 변수의 이름입니다. + * `main:app`이 파이썬의 `import` 문법과 흡사한 면이 있다는 걸 알 수 있습니다: + + ```Python + from main import app + ``` + + * 곧, `main:app`안에 있는 콜론의 의미는 파이썬에서 `from main import app`에서의 `import`와 같습니다. +* `--workers`: 사용할 워커 프로세스의 개수이며 숫자만큼의 유비콘 워커를 실행합니다. 이 예제에서는 4개의 워커를 실행합니다. +* `--worker-class`: 워커 프로세스에서 사용하기 위한 구니콘과 호환되는 워커클래스. + * 이런식으로 구니콘이 import하여 사용할 수 있는 클래스를 전달해줍니다: + + ```Python + import uvicorn.workers.UvicornWorker + ``` + +* `--bind`: 구니콘이 관찰할 IP와 포트를 의미합니다. 콜론 (`:`)을 사용하여 IP와 포트를 구분합니다. + * 만약에 `--bind 0.0.0.0:80` (구니콘 옵션) 대신 유비콘을 직접 실행하고 싶다면 `--host 0.0.0.0`과 `--port 80`을 사용해야 합니다. + +출력에서 각 프로세스에 대한 **PID** (process ID)를 확인할 수 있습니다.

Sıradaki şey ise Flask için bir "Django REST Framework"! + +!!! check "**FastAPI**'a nasıl ilham verdi?" + Gereken araçları ve parçaları birleştirip eşleştirmeyi kolaylaştıracak bir mikro framework olmalı. + + Basit ve kullanması kolay bir yönlendirme sistemine sahip olmalı. + +### Requests + +**FastAPI** aslında **Requests**'in bir alternatifi değil.

Yani, bir API için Swagger dökümantasyonu oluşturmak bu arayüzü otomatik olarak kullanabilmek demekti. + +Swagger bir noktada Linux Foundation'a verildi ve adı OpenAPI olarak değiştirildi. + +İşte bu yüzden versiyon 2.0 hakkında konuşurken "Swagger", versiyon 3 ve üzeri için ise "OpenAPI" adını kullanmak daha yaygın. + +!!! check "**FastAPI**'a nasıl ilham verdi?" + API spesifikasyonları için özel bir şema yerine bir açık standart benimseyip kullanmalı. + + Ayrıca standarda bağlı kullanıcı arayüzü araçlarını entegre etmeli: + + * Swagger UI + * ReDoc + + Yukarıdaki ikisi oldukça popüler ve istikrarlı olduğu için seçildi, ancak hızlı bir araştırma yaparak **FastAPI** ile kullanabileceğiniz pek çok OpenAPI alternatifi arayüz bulabilirsiniz. + +### Flask REST framework'leri + +Pek çok Flask REST framework'ü var, fakat bunları biraz araştırdıktan sonra pek çoğunun artık geliştirilmediğini ve göze batan bazı sorunlarının olduğunu gördüm. + +### Marshmallow + +API sistemlerine gereken ana özelliklerden biri de koddan veriyi alıp ağ üzerinde gönderilebilecek bir şeye çevirmek, yani veri dönüşümü. Bu işleme veritabanındaki veriyi içeren bir objeyi JSON objesine çevirmek, `datetime` objelerini metinlere çevirmek gibi örnekler verilebilir. + +API'lara gereken bir diğer büyük özellik ise veri doğrulamadır, yani verinin çeşitli parametrelere bağlı olarak doğru ve tutarlı olduğundan emin olmaktır. Örneğin bir alanın `int` olmasına karar verdiniz, daha sonra rastgele bir metin değeri almasını istemezsiniz. Bu özellikle sisteme dışarıdan gelen veri için kullanışlı bir özellik oluyor. + +Bir veri doğrulama sistemi olmazsa bütün bu kontrolleri koda dökerek kendiniz yapmak zorunda kalırdınız. + +Marshmallow bu özellikleri sağlamak için geliştirilmişti. Benim de geçmişte oldukça sık kullandığım harika bir kütüphanedir. + +Ama... Python'un tip belirteçleri gelmeden önce oluşturulmuştu. Yani her şemayı tanımlamak için Marshmallow'un sunduğu spesifik araçları ve sınıfları kullanmanız gerekiyordu. + +!!! check "**FastAPI**'a nasıl ilham verdi?" + Kod kullanarak otomatik olarak veri tipini ve veri doğrulamayı belirten "şemalar" tanımlamalı. + +### Webargs + +API'ların ihtiyacı olan bir diğer önemli özellik ise gelen isteklerdeki verileri Python objelerine ayrıştırabilmektir. + +Webargs, Flask gibi bir kaç framework'ün üzerinde bunu sağlamak için geliştirilen bir araçtır. + +Veri doğrulama için arka planda Marshmallow kullanıyor, hatta aynı geliştiriciler tarafından oluşturuldu. + +Webargs da harika bir araç ve onu da geçmişte henüz **FastAPI** yokken çok kullandım. + +!!! info "Bilgi" + Webargs aynı Marshmallow geliştirileri tarafından oluşturuldu. + +!!! check "**FastAPI**'a nasıl ilham verdi?" + Gelen istek verisi için otomatik veri doğrulamaya sahip olmalı. + +### APISpec + +Marshmallow ve Webargs eklentiler olarak; veri doğrulama, ayrıştırma ve dönüştürmeyi sağlıyor. + +Ancak dökümantasyondan hala ses seda yok. Daha sonrasında ise APISpec geldi. + +APISpec pek çok framework için bir eklenti olarak kullanılıyor (Starlette için de bir eklentisi var). + +Şemanın tanımını yol'a istek geldiğinde çalışan her bir fonksiyonun döküman dizesinin içine YAML formatında olacak şekilde yazıyorsunuz o da OpenAPI şemaları üretiyor. + +Flask, Starlette, Responder ve benzerlerinde bu şekilde çalışıyor. + +Fakat sonrasında yine mikro sözdizimi problemiyle karşılaşıyoruz. Python metinlerinin içinde koskoca bir YAML oluyor. + +Editör bu konuda pek yardımcı olamaz. Üstelik eğer parametreleri ya da Marshmallow şemalarını değiştirip YAML kodunu güncellemeyi unutursak artık döküman geçerliliğini yitiriyor. + +!!! info "Bilgi" + APISpec de aynı Marshmallow geliştiricileri tarafından oluşturuldu. + +!!! check "**FastAPI**'a nasıl ilham verdi?" + API'lar için açık standart desteği olmalı (OpenAPI gibi). + +### Flask-apispec + +Flask-apispec ise Webargs, Marshmallow ve APISpec'i birbirine bağlayan bir Flask eklentisi. + +Webargs ve Marshmallow'daki bilgiyi APISpec ile otomatik OpenAPI şemaları üretmek için kullanıyor. + +Hak ettiği değeri görmeyen, harika bir araç. Piyasadaki çoğu Flask eklentisinden çok daha popüler olmalı. Hak ettiği değeri görmüyor oluşunun sebebi ise dökümantasyonun çok kısa ve soyut olması olabilir. + +Böylece Flask-apispec, Python döküman dizilerine YAML gibi farklı bir syntax yazma sorununu çözmüş oldu. + +**FastAPI**'ı geliştirene dek benim favori arka uç kombinasyonum Flask'in yanında Marshmallow ve Webargs ile birlikte Flask-apispec idi. + +Bunu kullanmak, bir kaç full-stack Flask projesi oluşturucusunun yaratılmasına yol açtı. Bunlar benim (ve bir kaç harici ekibin de) şimdiye kadar kullandığı asıl stackler: + +* https://github.com/tiangolo/full-stack +* https://github.com/tiangolo/full-stack-flask-couchbase +* https://github.com/tiangolo/full-stack-flask-couchdb + +Aynı full-stack üreticiler [**FastAPI** Proje Üreticileri](project-generation.md){.internal-link target=_blank}'nin de temelini oluşturdu. + +!!! info "Bilgi" + Flask-apispec de aynı Marshmallow geliştiricileri tarafından üretildi. + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Veri dönüşümü ve veri doğrulamayı tanımlayan kodu kullanarak otomatik olarak OpenAPI şeması oluşturmalı. + +### NestJS (and Angular) + +Bu Python teknolojisi bile değil. NestJS, Angulardan ilham almış olan bir JavaScript (TypeScript) NodeJS framework'ü. + +Flask-apispec ile yapılabileceklere nispeten benzeyen bir şey elde ediyor. + +Angular 2'den ilham alan, içine gömülü bir bağımlılık enjeksiyonu sistemi var. Bildiğim diğer tüm bağımlılık enjeksiyonu sistemlerinde olduğu gibi"bağımlılık"ları önceden kaydetmenizi gerektiriyor. Böylece projeyi daha detaylı hale getiriyor ve kod tekrarını da arttırıyor. + +Parametreler TypeScript tipleri (Python tip belirteçlerine benzer) ile açıklandığından editör desteği oldukça iyi. + +Ama TypeScript verileri kod JavaScript'e derlendikten sonra korunmadığından, bunlara dayanarak aynı anda veri doğrulaması, veri dönüşümü ve dökümantasyon tanımlanamıyor. Bundan ve bazı tasarım tercihlerinden dolayı veri doğrulaması, dönüşümü ve otomatik şema üretimi için pek çok yere dekorator eklemek gerekiyor. Bu da projeyi oldukça detaylandırıyor. + +İç içe geçen derin modelleri pek iyi işleyemiyor. Yani eğer istekteki JSON gövdesi derin bir JSON objesiyse düzgün bir şekilde dökümante edilip doğrulanamıyor. + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Güzel bir editör desteği için Python tiplerini kullanmalı. + + Güçlü bir bağımlılık enjeksiyon sistemine sahip olmalı. Kod tekrarını minimuma indirecek bir yol bulmalı. + +### Sanic + +Sanic, `asyncio`'ya dayanan son derece hızlı Python kütüphanelerinden biriydi. Flask'a epey benzeyecek şekilde geliştirilmişti. + +!!! note "Teknik detaylar" + İçerisinde standart Python `asyncio` döngüsü yerine `uvloop` kullanıldı. Hızının asıl kaynağı buydu. + + Uvicorn ve Starlette'e ilham kaynağı olduğu oldukça açık, şu anda ikisi de açık karşılaştırmalarda Sanicten daha hızlı gözüküyor. + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Uçuk performans sağlayacak bir yol bulmalı. + + Tam da bu yüzden **FastAPI** Starlette'e dayanıyor, çünkü Starlette şu anda kullanılabilir en hızlı framework. (üçüncü parti karşılaştırmalı testlerine göre) + +### Falcon + +Falcon ise bir diğer yüksek performanslı Python framework'ü. Minimal olacak şekilde Hug gibi diğer framework'lerin temeli olabilmek için tasarlandı. + +İki parametre kabul eden fonksiyonlar şeklinde tasarlandı, biri "istek" ve diğeri ise "cevap". Sonra isteğin çeşitli kısımlarını **okuyor**, cevaba ise bir şeyler **yazıyorsunuz**. Bu tasarımdan dolayı istek parametrelerini ve gövdelerini standart Python tip belirteçlerini kullanarak fonksiyon parametreleriyle belirtmek mümkün değil. + +Yani veri doğrulama, veri dönüştürme ve dökümantasyonun hepsi kodda yer almalı, otomatik halledemiyoruz. Ya da Falcon üzerine bir framework olarak uygulanmaları gerekiyor, aynı Hug'da olduğu gibi. Bu ayrım Falcon'un tasarımından esinlenen, istek ve cevap objelerini parametre olarak işleyen diğer kütüphanelerde de yer alıyor. + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Harika bir performans'a sahip olmanın yollarını bulmalı. + + Hug ile birlikte (Hug zaten Falcon'a dayandığından) **FastAPI**'ın fonksiyonlarda `cevap` parametresi belirtmesinde ilham kaynağı oldu. + + FastAPI'da opsiyonel olmasına rağmen, daha çok header'lar, çerezler ve alternatif durum kodları belirlemede kullanılıyor. + +### Molten + +**FastAPI**'ı geliştirmenin ilk aşamalarında Molten'ı keşfettim. Pek çok ortak fikrimiz vardı: + +* Python'daki tip belirteçlerini baz alıyordu. +* Bunlara bağlı olarak veri doğrulaması ve dökümantasyon sağlıyordu. +* Bir bağımlılık enjeksiyonu sistemi vardı. + +Veri doğrulama, veri dönüştürme ve dökümantasyon için Pydantic gibi bir üçüncü parti kütüphane kullanmıyor, kendi içerisinde bunlara sahip. Yani bu veri tipi tanımlarını tekrar kullanmak pek de kolay değil. + +Biraz daha detaylı ayarlamalara gerek duyuyor. Ayrıca ASGI yerine WSGI'a dayanıyor. Yani Uvicorn, Starlette ve Sanic gibi araçların yüksek performansından faydalanacak şekilde tasarlanmamış. + +Bağımlılık enjeksiyonu sistemi bağımlılıkların önceden kaydedilmesini ve sonrasında belirlenen veri tiplerine göre çözülmesini gerektiriyor. Yani spesifik bir tip, birden fazla bileşen ile belirlenemiyor. + +Yol'lar fonksiyonun üstünde endpoint'i işleyen dekoratörler yerine farklı yerlerde tanımlanan fonksiyonlarla belirlenir. Bu Flask (ve Starlette) yerine daha çok Django'nun yaklaşımına daha yakın bir metot. Bu, kodda nispeten birbiriyle sıkı ilişkili olan şeyleri ayırmaya sebep oluyor. + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Model özelliklerinin "standart" değerlerini kullanarak veri tipleri için ekstra veri doğrulama koşulları tanımlamalı. Bu editör desteğini geliştiriyor ve daha önceden Pydantic'te yoktu. + + Bu aslında Pydantic'in de aynı doğrulama stiline geçmesinde ilham kaynağı oldu. Şu anda bütün bu özellikler Pydantic'in yapısında yer alıyor. + +### Hug + +Hug, Python tip belirteçlerini kullanarak API parametrelerinin tipini belirlemeyi uygulayan ilk framework'lerdendi. Bu, diğer araçlara da ilham kaynağı olan harika bir fikirdi. + +Tip belirlerken standart Python veri tipleri yerine kendi özel tiplerini kullandı, yine de bu ileriye dönük devasa bir adımdı. + +Hug ayrıca tüm API'ı JSON ile ifade eden özel bir şema oluşturan ilk framework'lerdendir. + +OpenAPI veya JSON Şeması gibi bir standarda bağlı değildi. Yani Swagger UI gibi diğer araçlarla entegre etmek kolay olmazdı. Ama yine de, bu oldukça yenilikçi bir fikirdi. + +Ayrıca ilginç ve çok rastlanmayan bir özelliği vardı: aynı framework'ü kullanarak hem API'lar hem de CLI'lar oluşturmak mümkündü. + +Senkron çalışan Python web framework'lerinin standardına (WSGI) dayandığından dolayı Websocket'leri ve diğer şeyleri işleyemiyor, ancak yine de yüksek performansa sahip. + +!!! info "Bilgi" + Hug, Python dosyalarında bulunan dahil etme satırlarını otomatik olarak sıralayan harika bir araç olan `isort`'un geliştiricisi Timothy Crosley tarafından geliştirildi. + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Hug, APIStar'ın çeşitli kısımlarında esin kaynağı oldu ve APIStar'la birlikte en umut verici bulduğum araçlardan biriydi. + + **FastAPI**, Python tip belirteçlerini kullanarak parametre belirlemede ve API'ı otomatık tanımlayan bir şema üretmede de Hug'a esinlendi. + + **FastAPI**'ın header ve çerez tanımlamak için fonksiyonlarda `response` parametresini belirtmesinde de Hug'dan ilham alındı. + +### APIStar (<= 0.5) + +**FastAPI**'ı geliştirmeye başlamadan hemen önce **APIStar** sunucusunu buldum. Benim aradığım şeylerin neredeyse hepsine sahipti ve harika bir tasarımı vardı. + +Benim şimdiye kadar gördüğüm Python tip belirteçlerini kullanarak parametre ve istekler belirlemeyi uygulayan ilk framework'lerdendi (Molten ve NestJS'den önce). APIStar'ı da aşağı yukarı Hug ile aynı zamanlarda buldum. Fakat APIStar OpenAPI standardını kullanıyordu. + +Farklı yerlerdeki tip belirteçlerine bağlı olarak otomatik veri doğrulama, veri dönüştürme ve OpenAPI şeması oluşturma desteği sunuyordu. + +Gövde şema tanımları Pydantic ile aynı Python tip belirteçlerini kullanmıyordu, biraz daha Marsmallow'a benziyordu. Dolayısıyla editör desteği de o kadar iyi olmazdı ama APIStar eldeki en iyi seçenekti. + +O dönemlerde karşılaştırmalarda en iyi performansa sahipti (yalnızca Starlette'e kaybediyordu). + +Başlangıçta otomatik API dökümantasyonu sunan bir web arayüzü yoktu, ama ben ona Swagger UI ekleyebileceğimi biliyordum. + +Bağımlılık enjeksiyon sistemi vardı. Yukarıda bahsettiğim diğer araçlar gibi bundaki sistem de bileşenlerin önceden kaydedilmesini gerektiriyordu. Yine de harika bir özellikti. + +Güvenlik entegrasyonu olmadığından dolayı APIStar'ı hiç bir zaman tam bir projede kullanamadım. Bu yüzden Flask-apispec'e bağlı full-stack proje üreticilerde sahip olduğum özellikleri tamamen değiştiremedim. Bu güvenlik entegrasyonunu ekleyen bir PR oluşturmak da projelerim arasında yer alıyordu. + +Sonrasında ise projenin odağı değişti. + +Geliştiricinin Starlette'e odaklanması gerekince proje de artık bir API web framework'ü olmayı bıraktı. + +Artık APIStar, OpenAPI özelliklerini doğrulamak için bir dizi araç sunan bir proje haline geldi. + +!!! info "Bilgi" + APIStar, aşağıdaki projeleri de üreten Tom Christie tarafından geliştirildi: + + * Django REST Framework + * **FastAPI**'ın da dayandığı Starlette + * Starlette ve **FastAPI** tarafından da kullanılan Uvicorn + +!!! check "**FastAPI**'a nasıl ilham oldu?" + Var oldu. + + Aynı Python veri tipleriyle birden fazla şeyi belirleme (veri doğrulama, veri dönüştürme ve dökümantasyon), bir yandan da harika bir editör desteği sunma, benim muhteşem bulduğum bir fikirdi. + + Uzunca bir süre boyunca benzer bir framework arayıp pek çok farklı alternatifi denedikten sonra, APIStar en iyi seçenekti. + + Sonra APIStar bir sunucu olmayı bıraktı ve Starlette oluşturuldu. Starlette, böyle bir sunucu sistemi için daha iyi bir temel sunuyordu. Bu da **FastAPI**'ın son esin kaynağıydı. + + Ben bu önceki araçlardan öğrendiklerime dayanarak **FastAPI**'ın özelliklerini arttırıp geliştiriyor, tip desteği sistemi ve diğer kısımları iyileştiriyorum ancak yine de **FastAPI**'ı APIStar'ın "ruhani varisi" olarak görüyorum. + +## **FastAPI** Tarafından Kullanılanlar + +### Pydantic + +Pydantic Python tip belirteçlerine dayanan; veri doğrulama, veri dönüştürme ve dökümantasyon tanımlamak (JSON Şema kullanarak) için bir kütüphanedir. + +Tip belirteçleri kullanıyor olması onu aşırı sezgisel yapıyor. + +Marshmallow ile karşılaştırılabilir.

Yalnızca bir sunucu olan Uvicorn'a yeniliyor, o da zaten bir framework değil. + +Starlette bütün temel web mikro framework işlevselliğini sağlıyor. + +Ancak otomatik veri doğrulama, veri dönüştürme ve dökümantasyon sağlamyor. + +Bu, **FastAPI**'ın onun üzerine tamamen Python tip belirteçlerine bağlı olarak eklediği (Pydantic ile) ana şeylerden biri. **FastAPI** bunun yanında artı olarak bağımlılık enjeksiyonu sistemi, güvenlik araçları, OpenAPI şema üretimi ve benzeri özellikler de ekliyor. + +!!! note "Teknik Detaylar" + ASGI, Django'nun ana ekibi tarafından geliştirilen yeni bir "standart". Bir "Python standardı" (PEP) olma sürecinde fakat henüz bir standart değil. + + Bununla birlikte, halihazırda birçok araç tarafından bir "standart" olarak kullanılmakta.

Bu, normal "sequentıal" (sıralı) kod gibi görünmesini ve doğru anlarda sizin için "awaıt" ile bekleme yapmasını sağlar. + +Sonuçları vermeden önce beklemeyi gerektirecek ve yeni Python özelliklerini destekleyen bir işlem olduğunda aşağıdaki gibi kodlayabilirsiniz: + +```Python +burgers = await get_burgers(2) +``` + +Buradaki `await` anahtari Python'a, sonuçları `burgers` degiskenine atamadan önce `get_burgers(2)` kodunun işini bitirmesini 🕙 beklemesi gerektiğini söyler. Bununla Python, bu ara zamanda başka bir şey 🔀 ⏯ yapabileceğini bilecektir (başka bir istek almak gibi). + + `await`kodunun çalışması için, eşzamansızlığı destekleyen bir fonksiyonun içinde olması gerekir. Bunu da yapmak için fonksiyonu `async def` ile tanımlamamız yeterlidir: + +```Python hl_lines="1" +async def get_burgers(number: int): + # burgerleri oluşturmak için asenkron birkaç iş + return burgers +``` + +...`def` yerine: + +```Python hl_lines="2" +# bu kod asenkron değil +def get_sequential_burgers(number: int): + # burgerleri oluşturmak için senkron bırkaç iş + return burgers +``` + +`async def` ile Python, bu fonksıyonun içinde, `await` ifadelerinin farkında olması gerektiğini ve çalışma zamanı gelmeden önce bu işlevin yürütülmesini "duraklatabileceğini" ve başka bir şey yapabileceğini 🔀 bilir. + +`async def` fonksiyonunu çağırmak istediğinizde, onu "awaıt" ıle kullanmanız gerekir. Yani, bu işe yaramaz: + +```Python +# Bu işe yaramaz, çünkü get_burgers, şu şekilde tanımlandı: async def +burgers = get_burgers(2) +``` + +--- + +Bu nedenle, size onu `await` ile çağırabileceğinizi söyleyen bir kitaplık kullanıyorsanız, onu `async def` ile tanımlanan *path fonksiyonu* içerisinde kullanmanız gerekir, örneğin: + +```Python hl_lines="2-3" +@app.get('/burgers') +async def read_burgers(): + burgers = await get_burgers(2) + return burgers +``` + +### Daha fazla teknik detay + +`await` in yalnızca `async def` ile tanımlanan fonksıyonların içinde kullanılabileceğini fark etmişsinizdir. + +Ama aynı zamanda, `async def` ile tanımlanan fonksiyonların "await" ile beklenmesi gerekir. Bu nedenle, "`async def` içeren fonksiyonlar yalnızca "`async def` ile tanımlanan fonksiyonların içinde çağrılabilir. + + +Yani yumurta mı tavukdan, tavuk mu yumurtadan gibi ilk `async` fonksiyonu nasıl çağırılır? + +**FastAPI** ile çalışıyorsanız bunun için endişelenmenize gerek yok, çünkü bu "ilk" fonksiyon sizin *path fonksiyonunuz* olacak ve FastAPI doğru olanı nasıl yapacağını bilecek. + +Ancak FastAPI olmadan `async` / `await` kullanmak istiyorsanız, resmi Python belgelerini kontrol edin. + +### Asenkron kodun diğer biçimleri + +Bu `async` ve `await` kullanimi oldukça yenidir. + +Ancak asenkron kodla çalışmayı çok daha kolay hale getirir. + +Aynı sözdizimi (hemen hemen aynı) son zamanlarda JavaScript'in modern sürümlerine de dahil edildi (Tarayıcı ve NodeJS'de). + +Ancak bundan önce, asenkron kodu işlemek oldukça karmaşık ve zordu. + +Python'un önceki sürümlerinde, threadlerı veya Gevent kullanıyor olabilirdin. Ancak kodu anlamak, hata ayıklamak ve düşünmek çok daha karmaşık olurdu. + +NodeJS / Browser JavaScript'in önceki sürümlerinde, "callback" kullanırdınız. Bu da callbacks cehennemine yol açar. + +## Coroutine'ler + +**Coroutine**, bir `async def` fonksiyonu tarafından döndürülen değer için çok süslü bir terimdir. Python bunun bir fonksiyon gibi bir noktada başlayıp biteceğini bilir, ancak içinde bir `await` olduğunda dahili olarak da duraklatılabilir ⏸. + +Ancak, `async` ve `await` ile asenkron kod kullanmanın tüm bu işlevselliği, çoğu zaman "Coroutine" kullanmak olarak adlandırılır. Go'nun ana özelliği olan "Goroutines" ile karşılaştırılabilir. + +## Sonuç + +Aynı ifadeyi yukarıdan görelim: + +> Python'ın modern sürümleri, **"async" ve "await"** sözdizimi ile birlikte **"coroutines"** adlı bir özelliği kullanan **"asenkron kod"** desteğine sahiptir. + +Şimdi daha mantıklı gelmeli. ✨ + +FastAPI'ye (Starlette aracılığıyla) güç veren ve bu kadar etkileyici bir performansa sahip olmasını sağlayan şey budur. + +## Çok Teknik Detaylar + +!!! warning + Muhtemelen burayı atlayabilirsiniz. + + Bunlar, **FastAPI**'nin altta nasıl çalıştığına dair çok teknik ayrıntılardır. + + Biraz teknik bilginiz varsa (co-routines, threads, blocking, vb)ve FastAPI'nin "async def" ile normal "def" arasındaki farkı nasıl işlediğini merak ediyorsanız, devam edin. + +### Path fonksiyonu + +"async def" yerine normal "def" ile bir *yol işlem işlevi* bildirdiğinizde, doğrudan çağrılmak yerine (sunucuyu bloke edeceğinden) daha sonra beklenen harici bir iş parçacığı havuzunda çalıştırılır. + +Yukarıda açıklanan şekilde çalışmayan başka bir asenkron framework'den geliyorsanız ve küçük bir performans kazancı (yaklaşık 100 nanosaniye) için "def" ile *path fonksiyonu* tanımlamaya alışkınsanız, **FastAPI**'de tam tersi olacağını unutmayın. Bu durumlarda, *path fonksiyonu* G/Ç engelleyen durum oluşturmadıkça "async def" kullanmak daha iyidir. + +Yine de, her iki durumda da, **FastAPI**'nin önceki frameworkden [hala daha hızlı](/#performance){.internal-link target=_blank} (veya en azından karşılaştırılabilir) olma olasılığı vardır. + +### Bagımlılıklar + +Aynısı bağımlılıklar için de geçerlidir.

Наприклад, перетворення об’єкта, що містить дані з бази даних, на об’єкт JSON. Перетворення об’єктів `datetime` на строки тощо. + +Іншою важливою функцією, необхідною для API, є перевірка даних, яка забезпечує дійсність даних за певними параметрами. Наприклад, що деяке поле є `int`, а не деяка випадкова строка. Це особливо корисно для вхідних даних. + +Без системи перевірки даних вам довелося б виконувати всі перевірки вручну, у коді. + +Marshmallow створено для забезпечення цих функцій. Це чудова бібліотека, і я часто нею користувався раніше. + +Але він був створений до того, як існували підказки типу Python. Отже, щоб визначити кожну схему, вам потрібно використовувати спеціальні утиліти та класи, надані Marshmallow. + +!!! Перегляньте "Надихнуло **FastAPI** на" + Використовувати код для автоматичного визначення "схем", які надають типи даних і перевірку. + +### Webargs + +Іншою важливою функцією, необхідною для API, є аналіз даних із вхідних запитів. + +Webargs — це інструмент, створений, щоб забезпечити це поверх кількох фреймворків, включаючи Flask. + +Він використовує Marshmallow в основі для перевірки даних. І створений тими ж розробниками. + +Це чудовий інструмент, і я також часто використовував його, перш ніж створити **FastAPI**. + +!!! Інформація + Webargs був створений тими ж розробниками Marshmallow. + +!!! Перегляньте "Надихнуло **FastAPI** на" + Мати автоматичну перевірку даних вхідного запиту. + +### APISpec + +Marshmallow і Webargs забезпечують перевірку, аналіз і серіалізацію як плагіни. + +Але документація досі відсутня. Потім було створено APISpec. + +Це плагін для багатьох фреймворків (також є плагін для Starlette). + +Принцип роботи полягає в тому, що ви пишете визначення схеми, використовуючи формат YAML, у docstring кожної функції, що обробляє маршрут. + +І він генерує схеми OpenAPI. + +Так це працює у Flask, Starlette, Responder тощо. + +Але потім ми знову маємо проблему наявності мікросинтаксису всередині Python строки (великий YAML). + +Редактор тут нічим не може допомогти. І якщо ми змінимо параметри чи схеми Marshmallow і забудемо також змінити цю строку документа YAML, згенерована схема буде застарілою. + +!!! Інформація + APISpec був створений тими ж розробниками Marshmallow. + + +!!! Перегляньте "Надихнуло **FastAPI** на" + Підтримувати відкритий стандарт API, OpenAPI. + +### Flask-apispec + +Це плагін Flask, який об’єднує Webargs, Marshmallow і APISpec. + +Він використовує інформацію з Webargs і Marshmallow для автоматичного створення схем OpenAPI за допомогою APISpec. + +Це чудовий інструмент, дуже недооцінений. Він має бути набагато популярнішим, ніж багато плагінів Flask. Це може бути пов’язано з тим, що його документація надто стисла й абстрактна. + +Це вирішило необхідність писати YAML (інший синтаксис) всередині рядків документів Python. + +Ця комбінація Flask, Flask-apispec із Marshmallow і Webargs була моїм улюбленим бекенд-стеком до створення **FastAPI**. + +Їі використання призвело до створення кількох генераторів повного стека Flask. Це основний стек, який я (та кілька зовнішніх команд) використовував досі: + +* https://github.com/tiangolo/full-stack +* https://github.com/tiangolo/full-stack-flask-couchbase +* https://github.com/tiangolo/full-stack-flask-couchdb + +І ці самі генератори повного стеку були основою [**FastAPI** генераторів проектів](project-generation.md){.internal-link target=_blank}. + +!!!

Перегляньте "Надихнуло **FastAPI** на" + Створення схеми OpenAPI автоматично з того самого коду, який визначає серіалізацію та перевірку. + +### NestJS (та Angular) + +Це навіть не Python, NestJS — це фреймворк NodeJS JavaScript (TypeScript), натхненний Angular. + +Це досягає чогось подібного до того, що можна зробити з Flask-apispec. + +Він має інтегровану систему впровадження залежностей, натхненну Angular two. Він потребує попередньої реєстрації «injectables» (як і всі інші системи впровадження залежностей, які я знаю), тому це збільшує багатослівність та повторення коду. + +Оскільки параметри описані за допомогою типів TypeScript (подібно до підказок типу Python), підтримка редактора досить хороша. + +Але оскільки дані TypeScript не зберігаються після компіляції в JavaScript, вони не можуть покладатися на типи для визначення перевірки, серіалізації та документації одночасно. Через це та деякі дизайнерські рішення, щоб отримати перевірку, серіалізацію та автоматичну генерацію схеми, потрібно додати декоратори в багатьох місцях. Таким чином код стає досить багатослівним. + +Він не дуже добре обробляє вкладені моделі. Отже, якщо тіло JSON у запиті є об’єктом JSON із внутрішніми полями, які, у свою чергу, є вкладеними об’єктами JSON, його неможливо належним чином задокументувати та перевірити. + +!!!

Примітка "Технічні деталі" + Він використовував `uvloop` замість стандартного циклу Python `asyncio`. Ось що зробило його таким швидким. + + Це явно надихнуло Uvicorn і Starlette, які зараз швидші за Sanic у відкритих тестах. + +!!! Перегляньте "Надихнуло **FastAPI** на" + Знайти спосіб отримати божевільну продуктивність. + + Ось чому **FastAPI** базується на Starlette, оскільки це найшвидша доступна структура (перевірена тестами сторонніх розробників). + +### Falcon + +Falcon — ще один високопродуктивний фреймворк Python, він розроблений як мінімальний і працює як основа інших фреймворків, таких як Hug. + +Він розроблений таким чином, щоб мати функції, які отримують два параметри, один «запит» і один «відповідь». Потім ви «читаєте» частини запиту та «записуєте» частини у відповідь. Через такий дизайн неможливо оголосити параметри запиту та тіла за допомогою стандартних підказок типу Python як параметри функції. + +Таким чином, перевірка даних, серіалізація та документація повинні виконуватися в коді, а не автоматично. Або вони повинні бути реалізовані як фреймворк поверх Falcon, як Hug. Така сама відмінність спостерігається в інших фреймворках, натхненних дизайном Falcon, що мають один об’єкт запиту та один об’єкт відповіді як параметри. + +!!! Перегляньте "Надихнуло **FastAPI** на" + Знайти способи отримати чудову продуктивність. + + Разом із Hug (оскільки Hug базується на Falcon) надихнув **FastAPI** оголосити параметр `response` у функціях. + + Хоча у FastAPI це необов’язково, і використовується в основному для встановлення заголовків, файлів cookie та альтернативних кодів стану. + +### Molten + +Я відкрив для себе Molten на перших етапах створення **FastAPI**. І він має досить схожі ідеї: + +* Базується на підказках типу Python. +* Перевірка та документація цих типів. +* Система впровадження залежностей. + +Він не використовує перевірку даних, серіалізацію та бібліотеку документації сторонніх розробників, як Pydantic, він має свою власну. Таким чином, ці визначення типів даних не можна було б використовувати повторно так легко. + +Це вимагає трохи більш докладних конфігурацій. І оскільки він заснований на WSGI (замість ASGI), він не призначений для використання високопродуктивних інструментів, таких як Uvicorn, Starlette і Sanic. + +Система впровадження залежностей вимагає попередньої реєстрації залежностей, і залежності вирішуються на основі оголошених типів. Отже, неможливо оголосити більше ніж один «компонент», який надає певний тип. + +Маршрути оголошуються в одному місці з використанням функцій, оголошених в інших місцях (замість використання декораторів, які можна розмістити безпосередньо поверх функції, яка обробляє кінцеву точку). Це ближче до того, як це робить Django, ніж до Flask (і Starlette). Він розділяє в коді речі, які відносно тісно пов’язані. + +!!! Перегляньте "Надихнуло **FastAPI** на" + Визначити додаткові перевірки для типів даних, використовуючи значення "за замовчуванням" атрибутів моделі. Це покращує підтримку редактора, а раніше вона була недоступна в Pydantic. + + Це фактично надихнуло оновити частини Pydantic, щоб підтримувати той самий стиль оголошення перевірки (всі ці функції вже доступні в Pydantic). + +### Hug + +Hug був одним із перших фреймворків, який реалізував оголошення типів параметрів API за допомогою підказок типу Python. Це була чудова ідея, яка надихнула інші інструменти зробити те саме. + +Він використовував спеціальні типи у своїх оголошеннях замість стандартних типів Python, але це все одно був величезний крок вперед. + +Це також був один із перших фреймворків, який генерував спеціальну схему, що оголошувала весь API у JSON. + +Він не базувався на таких стандартах, як OpenAPI та JSON Schema. Тому було б непросто інтегрувати його з іншими інструментами, як-от Swagger UI. Але знову ж таки, це була дуже інноваційна ідея. + +Він має цікаву незвичайну функцію: використовуючи ту саму структуру, можна створювати API, а також CLI. + +Оскільки він заснований на попередньому стандарті для синхронних веб-фреймворків Python (WSGI), він не може працювати з Websockets та іншими речами, хоча він також має високу продуктивність. + +!!! Інформація + Hug створив Тімоті Крослі, той самий творець `isort`, чудовий інструмент для автоматичного сортування імпорту у файлах Python. + +!!! Перегляньте "Надихнуло **FastAPI** на" + Hug надихнув частину APIStar і був одним із найбільш перспективних інструментів, поряд із APIStar. + + Hug надихнув **FastAPI** на використання підказок типу Python для оголошення параметрів і автоматичного створення схеми, що визначає API. + + Hug надихнув **FastAPI** оголосити параметр `response` у функціях для встановлення заголовків і файлів cookie. + +### APIStar (<= 0,5) + +Безпосередньо перед тим, як вирішити створити **FastAPI**, я знайшов сервер **APIStar**. Він мав майже все, що я шукав, і мав чудовий дизайн. + +Це була одна з перших реалізацій фреймворку, що використовує підказки типу Python для оголошення параметрів і запитів, яку я коли-небудь бачив (до NestJS і Molten). Я знайшов його більш-менш одночасно з Hug. Але APIStar використовував стандарт OpenAPI. + +Він мав автоматичну перевірку даних, серіалізацію даних і генерацію схеми OpenAPI на основі підказок того самого типу в кількох місцях. + +Визначення схеми тіла не використовували ті самі підказки типу Python, як Pydantic, воно було трохи схоже на Marshmallow, тому підтримка редактора була б не такою хорошою, але все ж APIStar був найкращим доступним варіантом. + +Він мав найкращі показники продуктивності на той час (перевершив лише Starlette). + +Спочатку він не мав автоматичного веб-інтерфейсу документації API, але я знав, що можу додати до нього інтерфейс користувача Swagger. + +Він мав систему введення залежностей. Він вимагав попередньої реєстрації компонентів, як і інші інструменти, розглянуті вище. Але все одно це була чудова функція. + +Я ніколи не міг використовувати його в повноцінному проекті, оскільки він не мав інтеграції безпеки, тому я не міг замінити всі функції, які мав, генераторами повного стеку на основі Flask-apispec. У моїх невиконаних проектах я мав створити запит на вилучення, додавши цю функцію. + +Але потім фокус проекту змінився. + +Це вже не був веб-фреймворк API, оскільки творцю потрібно було зосередитися на Starlette. + +Тепер APIStar — це набір інструментів для перевірки специфікацій OpenAPI, а не веб-фреймворк. + +!!! Інформація + APIStar створив Том Крісті.

Це стало останнім джерелом натхнення для створення **FastAPI**. Я вважаю **FastAPI** «духовним спадкоємцем» APIStar, удосконалюючи та розширюючи функції, систему введення тексту та інші частини на основі досвіду, отриманого від усіх цих попередніх інструментів. + +## Використовується **FastAPI** + +### Pydantic + +Pydantic — це бібліотека для визначення перевірки даних, серіалізації та документації (за допомогою схеми JSON) на основі підказок типу Python. + +Це робить його надзвичайно інтуїтивним. + +Його можна порівняти з Marshmallow.

Перевершує лише Uvicorn, який є не фреймворком, а сервером. + +Starlette надає всі основні функції веб-мікрофреймворку. + +Але він не забезпечує автоматичної перевірки даних, серіалізації чи документації. + +Це одна з головних речей, які **FastAPI** додає зверху, все на основі підказок типу Python (з використанням Pydantic).

+ +```console +$ uvicorn main:app --reload + +INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit) +``` + +
+ +Nếu bạn tạo ứng dụng của bạn giống như: + +```Python hl_lines="3" +{!../../../docs_src/first_steps/tutorial002.py!} +``` + +Và đặt nó trong một tệp tin `main.py`, sau đó bạn sẽ gọi `uvicorn` giống như: + +
+ +```console +$ uvicorn main:my_awesome_api --reload + +INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit) +``` + +

+ +```console +$ pip install fastapi + +---> 100% +``` + +
+ +你同時也會需要 ASGI 伺服器用於生產環境,像是 UvicornHypercorn。 + +
+ +```console +$ pip install "uvicorn[standard]" + +---> 100% +``` + +
+ +## 範例 + +### 建立 + +- 建立一個 python 檔案 `main.py`,並寫入以下程式碼: + +```Python +from typing import Union + +from fastapi import FastAPI + +app = FastAPI() + + +@app.get("/") +def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +def read_item(item_id: int, q: Union[str, None] = None): + return {"item_id": item_id, "q": q} +``` + +
+或可以使用 async def... + +如果你的程式使用 `async` / `await`,請使用 `async def`: + +```Python hl_lines="9 14" +from typing import Union + +from fastapi import FastAPI + +app = FastAPI() + + +@app.get("/") +async def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +async def read_item(item_id: int, q: Union[str, None] = None): + return {"item_id": item_id, "q": q} +``` + +**注意**: + +如果你不知道是否會用到,可以查看 _"In a hurry?"_ 章節中,關於 `async` 和 `await` 的部分。 + +
+ +### 運行 + +使用以下指令運行伺服器: + +
+ +```console +$ uvicorn main:app --reload + +INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit) +INFO: Started reloader process [28720] +INFO: Started server process [28722] +INFO: Waiting for application startup. +INFO: Application startup complete. +``` + +

并发汉堡 + +你和你的恋人一起去快餐店,你排队在后面,收银员从你前面的人接单。😍 + + + +然后轮到你了,你为你的恋人和你选了两个非常豪华的汉堡。🍔🍔 + + + +收银员对厨房里的厨师说了一些话,让他们知道他们必须为你准备汉堡(尽管他们目前正在为之前的顾客准备汉堡)。 + + + +你付钱了。 💸 + +收银员给你轮到的号码。 + + + +当你在等待的时候,你和你的恋人一起去挑选一张桌子,然后你们坐下来聊了很长时间(因为汉堡很豪华,需要一些时间来准备)。 + +当你和你的恋人坐在桌子旁,等待汉堡的时候,你可以用这段时间来欣赏你的恋人是多么的棒、可爱和聪明✨😍✨。 + + + +在等待中和你的恋人交谈时,你会不时地查看柜台上显示的号码,看看是否已经轮到你了。 + +然后在某个时刻,终于轮到你了。你去柜台拿汉堡然后回到桌子上。 + + + +你们享用了汉堡,整个过程都很开心。✨ + + + +!!! info + 漂亮的插画来自 Ketrina Thompson. 🎨 + +--- + +在那个故事里,假设你是计算机程序 🤖 。 + +当你在排队时,你只是闲着😴, 轮到你前不做任何事情(仅排队)。但排队很快,因为收银员只接订单(不准备订单),所以这一切都还好。 + +然后,当轮到你时,需要你做一些实际性的工作,比如查看菜单,决定你想要什么,让你的恋人选择,支付,检查你是否提供了正确的账单或卡,检查你的收费是否正确,检查订单是否有正确的项目,等等。 + +此时,即使你仍然没有汉堡,你和收银员的工作也"暂停"了⏸, 因为你必须等待一段时间 🕙 让你的汉堡做好。 + +但是,当你离开柜台并坐在桌子旁,在轮到你的号码前的这段时间,你可以将焦点切换到 🔀 你的恋人上,并做一些"工作"⏯ 🤓。你可以做一些非常"有成效"的事情,比如和你的恋人调情😍. + +之后,收银员 💁 把号码显示在显示屏上,并说到 "汉堡做好了",而当显示的号码是你的号码时,你不会立刻疯狂地跳起来。因为你知道没有人会偷你的汉堡,因为你有你的号码,而其他人又有他们自己的号码。 + +所以你要等待你的恋人完成故事(完成当前的工作⏯ /正在做的事🤓), 轻轻微笑,说你要吃汉堡⏸. + +然后你去柜台🔀, 到现在初始任务已经完成⏯, 拿起汉堡,说声谢谢,然后把它们送到桌上。这就完成了与计数器交互的步骤/任务⏹. 这反过来又产生了一项新任务,即"吃汉堡"🔀 ⏯, 上一个"拿汉堡"的任务已经结束了⏹. + +### 并行汉堡 + +现在让我们假设不是"并发汉堡",而是"并行汉堡"。 + +你和你的恋人一起去吃并行快餐。 + +你站在队伍中,同时是厨师的几个收银员(比方说8个)从前面的人那里接单。 + +你之前的每个人都在等待他们的汉堡准备好后才离开柜台,因为8名收银员都会在下一份订单前马上准备好汉堡。 + + + +然后,终于轮到你了,你为你的恋人和你订购了两个非常精美的汉堡。 + +你付钱了 💸。 + + + +收银员去厨房。 + +你站在柜台前 🕙等待着,这样就不会有人在你之前抢走你的汉堡,因为没有轮流的号码。 + + + +当你和你的恋人忙于不让任何人出现在你面前,并且在他们到来的时候拿走你的汉堡时,你无法关注到你的恋人。😞 + +这是"同步"的工作,你被迫与服务员/厨师 👨‍🍳"同步"。你在此必须等待 🕙 ,在收银员/厨师 👨‍🍳 完成汉堡并将它们交给你的确切时间到达之前一直等待,否则其他人可能会拿走它们。 + + + +你经过长时间的等待 🕙 ,收银员/厨师 👨‍🍳终于带着汉堡回到了柜台。 + + + +你拿着汉堡,和你的情人一起上桌。 + +你们仅仅是吃了它们,就结束了。⏹ + + + +没有太多的交谈或调情,因为大部分时间 🕙 都在柜台前等待😞。 + +!!! info + 漂亮的插画来自 Ketrina Thompson. 🎨 + +--- + +在这个并行汉堡的场景中,你是一个计算机程序 🤖 且有两个处理器(你和你的恋人),都在等待 🕙 ,并投入他们的注意力 ⏯ 在柜台上等待了很长一段时间。 + +这家快餐店有 8 个处理器(收银员/厨师)。而并发汉堡店可能只有 2 个(一个收银员和一个厨师)。 + +但最终的体验仍然不是最好的。😞 + +--- + +这将是与汉堡的类似故事。🍔 + +一种更"贴近生活"的例子,想象一家银行。 + +直到最近,大多数银行都有多个出纳员 👨‍💼👨‍💼👨‍💼👨‍💼 还有一条长长排队队伍🕙🕙🕙🕙🕙🕙🕙🕙。 + +所有收银员都是一个接一个的在客户面前做完所有的工作👨‍💼⏯. + +你必须经过 🕙 较长时间排队,否则你就没机会了。 + +你可不会想带你的恋人 😍 和你一起去银行办事🏦. + +### 汉堡结论 + +在"你与恋人一起吃汉堡"的这个场景中,因为有很多人在等待🕙, 使用并发系统更有意义⏸🔀⏯. + +大多数 Web 应用都是这样的。 + +你的服务器正在等待很多很多用户通过他们不太好的网络发送来的请求。 + +然后再次等待 🕙 响应回来。 + +这个"等待" 🕙 是以微秒为单位测量的,但总的来说,最后还是等待很久。 + +这就是为什么使用异步对于 Web API 很有意义的原因 ⏸🔀⏯。 + +这种异步机制正是 NodeJS 受到欢迎的原因(尽管 NodeJS 不是并行的),以及 Go 作为编程语言的优势所在。 + +这与 **FastAPI** 的性能水平相同。 + +您可以同时拥有并行性和异步性,您可以获得比大多数经过测试的 NodeJS 框架更高的性能,并且与 Go 不相上下, Go 是一种更接近于 C 的编译语言(全部归功于 Starlette)。 + +### 并发比并行好吗? + +不!这不是故事的本意。 + +并发不同于并行。而是在需要大量等待的特定场景下效果更好。因此,在 Web 应用程序开发中,它通常比并行要好得多,但这并不意味着全部。 + +因此,为了平衡这一点,想象一下下面的短篇故事: + +> 你必须打扫一个又大又脏的房子。 + +*是的,这就是完整的故事。* + +--- + +在任何地方, 都不需要等待 🕙 ,只需要在房子的多个地方做着很多工作。 + +你可以像汉堡的例子那样轮流执行,先是客厅,然后是厨房,但因为你不需要等待 🕙 ,对于任何事情都是清洁,清洁,还是清洁,轮流不会影响任何事情。 + +无论是否轮流执行(并发),都需要相同的时间来完成,而你也会完成相同的工作量。 + +但在这种情况下,如果你能带上 8 名前收银员/厨师,现在是清洁工一起清扫,他们中的每一个人(加上你)都能占据房子的一个区域来清扫,你就可以在额外的帮助下并行的更快地完成所有工作。 + +在这个场景中,每个清洁工(包括您)都将是一个处理器,完成这个工作的一部分。 + +由于大多数执行时间是由实际工作(而不是等待)占用的,并且计算机中的工作是由 CPU 完成的,所以他们称这些问题为"CPU 密集型"。 + +--- + +CPU 密集型操作的常见示例是需要复杂的数学处理。 + +例如: + +* **音频**或**图像**处理; +* **计算机视觉**: 一幅图像由数百万像素组成,每个像素有3种颜色值,处理通常需要同时对这些像素进行计算; +* **机器学习**: 它通常需要大量的"矩阵"和"向量"乘法。想象一个包含数字的巨大电子表格,并同时将所有数字相乘; +* **深度学习**: 这是机器学习的一个子领域,同样适用。只是没有一个数字的电子表格可以相乘,而是一个庞大的数字集合,在很多情况下,你需要使用一个特殊的处理器来构建和使用这些模型。 + +### 并发 + 并行: Web + 机器学习 + +使用 **FastAPI**,您可以利用 Web 开发中常见的并发机制的优势(NodeJS 的主要吸引力)。 + +并且,您也可以利用并行和多进程(让多个进程并行运行)的优点来处理与机器学习系统中类似的 **CPU 密集型** 工作。 + +这一点,再加上 Python 是**数据科学**、机器学习(尤其是深度学习)的主要语言这一简单事实,使得 **FastAPI** 与数据科学/机器学习 Web API 和应用程序(以及其他许多应用程序)非常匹配。 + +了解如何在生产环境中实现这种并行性,可查看此文 [Deployment](deployment/index.md){.internal-link target=_blank}。 + +## `async` 和 `await` + +现代版本的 Python 有一种非常直观的方式来定义异步代码。这使它看起来就像正常的"顺序"代码,并在适当的时候"等待"。 + +当有一个操作需要等待才能给出结果,且支持这个新的 Python 特性时,您可以编写如下代码: + +```Python +burgers = await get_burgers(2) +``` + +这里的关键是 `await`。它告诉 Python 它必须等待 ⏸ `get_burgers(2)` 完成它的工作 🕙 ,然后将结果存储在 `burgers` 中。这样,Python 就会知道此时它可以去做其他事情 🔀 ⏯ (比如接收另一个请求)。 + +要使 `await` 工作,它必须位于支持这种异步机制的函数内。因此,只需使用 `async def` 声明它: + +```Python hl_lines="1" +async def get_burgers(number: int): + # Do some asynchronous stuff to create the burgers + return burgers +``` + +...而不是 `def`: + +```Python hl_lines="2" +# This is not asynchronous +def get_sequential_burgers(number: int): + # Do some sequential stuff to create the burgers + return burgers +``` + +使用 `async def`,Python 就知道在该函数中,它将遇上 `await`,并且它可以"暂停" ⏸ 执行该函数,直至执行其他操作 🔀 后回来。 + +当你想调用一个 `async def` 函数时,你必须"等待"它。因此,这不会起作用: + +```Python +# This won't work, because get_burgers was defined with: async def +burgers = get_burgers(2) +``` + +--- + +因此,如果您使用的库告诉您可以使用 `await` 调用它,则需要使用 `async def` 创建路径操作函数 ,如: + +```Python hl_lines="2-3" +@app.get('/burgers') +async def read_burgers(): + burgers = await get_burgers(2) + return burgers +``` + +### 更多技术细节 + +您可能已经注意到,`await` 只能在 `async def` 定义的函数内部使用。 + +但与此同时,必须"等待"通过 `async def` 定义的函数。因此,带 `async def` 的函数也只能在 `async def` 定义的函数内部调用。 + +那么,这关于先有鸡还是先有蛋的问题,如何调用第一个 `async` 函数? + +如果您使用 **FastAPI**,你不必担心这一点,因为"第一个"函数将是你的路径操作函数,FastAPI 将知道如何做正确的事情。 + +但如果您想在没有 FastAPI 的情况下使用 `async` / `await`,则可以这样做。 + +### 编写自己的异步代码 + +Starlette (和 **FastAPI**) 是基于 AnyIO 实现的,这使得它们可以兼容 Python 的标准库 asyncioTrio。 + +特别是,你可以直接使用 AnyIO 来处理高级的并发用例,这些用例需要在自己的代码中使用更高级的模式。 + +即使您没有使用 **FastAPI**,您也可以使用 AnyIO 编写自己的异步程序,使其拥有较高的兼容性并获得一些好处(例如, 结构化并发)。 + +### 其他形式的异步代码 + +这种使用 `async` 和 `await` 的风格在语言中相对较新。 + +但它使处理异步代码变得容易很多。 + +这种相同的语法(或几乎相同)最近也包含在现代版本的 JavaScript 中(在浏览器和 NodeJS 中)。 + +但在此之前,处理异步代码非常复杂和困难。 + +在以前版本的 Python,你可以使用多线程或者 Gevent。但代码的理解、调试和思考都要复杂许多。 + +在以前版本的 NodeJS / 浏览器 JavaScript 中,你会使用"回调",因此也可能导致回调地狱。 + +## 协程 + +**协程**只是 `async def` 函数返回的一个非常奇特的东西的称呼。Python 知道它有点像一个函数,它可以启动,也会在某个时刻结束,而且它可能会在内部暂停 ⏸ ,只要内部有一个 `await`。 + +通过使用 `async` 和 `await` 的异步代码的所有功能大多数被概括为"协程"。它可以与 Go 的主要关键特性 "Goroutines" 相媲美。 + +## 结论 + +让我们再来回顾下上文所说的: + +> Python 的现代版本可以通过使用 `async` 和 `await` 语法创建**协程**,并用于支持**异步代码**。 + +现在应该能明白其含义了。✨ + +所有这些使得 FastAPI(通过 Starlette)如此强大,也是它拥有如此令人印象深刻的性能的原因。 + +## 非常技术性的细节 + +!!! warning + 你可以跳过这里。 + + 这些都是 FastAPI 如何在内部工作的技术细节。 + + 如果您有相当多的技术知识(协程、线程、阻塞等),并且对 FastAPI 如何处理 `async def` 与常规 `def` 感到好奇,请继续。 + +### 路径操作函数 + +当你使用 `def` 而不是 `async def` 来声明一个*路径操作函数*时,它运行在外部的线程池中并等待其结果,而不是直接调用(因为它会阻塞服务器)。 + +如果您使用过另一个不以上述方式工作的异步框架,并且您习惯于用普通的 `def` 定义普通的仅计算路径操作函数,以获得微小的性能增益(大约100纳秒),请注意,在 FastAPI 中,效果将完全相反。在这些情况下,最好使用 `async def`,除非路径操作函数内使用执行阻塞 I/O 的代码。 + +在这两种情况下,与您之前的框架相比,**FastAPI** 可能[仍然很快](/#performance){.internal-link target=_blank}。 + +### 依赖 + +这同样适用于[依赖](./tutorial/dependencies/index.md){.internal-link target=_blank}。如果一个依赖是标准的 `def` 函数而不是 `async def`,它将被运行在外部线程池中。 + +### 子依赖 + +你可以拥有多个相互依赖的依赖以及[子依赖](./tutorial/dependencies/sub-dependencies.md){.internal-link target=_blank} (作为函数的参数),它们中的一些可能是通过 `async def` 声明,也可能是通过 `def` 声明。它们仍然可以正常工作,这些通过 `def` 声明的函数将会在外部线程中调用(来自线程池),而不是"被等待"。 + +### 其他函数 + +您可直接调用通过 `def` 或 `async def` 创建的任何其他函数,FastAPI 不会影响您调用它们的方式。 + +这与 FastAPI 为您调用*路径操作函数*和依赖项的逻辑相反。 + +如果你的函数是通过 `def` 声明的,它将被直接调用(在代码中编写的地方),而不会在线程池中,如果这个函数通过 `async def` 声明,当在代码中调用时,你就应该使用 `await` 等待函数的结果。 + +--- + +再次提醒,这些是非常技术性的细节,如果你来搜索它可能对你有用。 + +否则,您最好应该遵守的指导原则赶时间吗?. diff --git

+接下来要考虑的概念都是关于运行实际 API 的程序(例如 Uvicorn)。 + +## 程序和进程 + +我们将讨论很多关于正在运行的“**进程**”的内容,因此弄清楚它的含义以及与“**程序**”这个词有什么区别是很有用的。 + +### 什么是程序 + +**程序**这个词通常用来描述很多东西: + +* 您编写的 **代码**,**Python 文件**。 +* 操作系统可以**执行**的**文件**,例如:`python`、`python.exe`或`uvicorn`。 +* 在操作系统上**运行**、使用CPU 并将内容存储在内存上的特定程序。 这也被称为**进程**。 + +### 什么是进程 + +**进程** 这个词通常以更具体的方式使用,仅指在操作系统中运行的东西(如上面的最后一点): + +* 在操作系统上**运行**的特定程序。 + * 这不是指文件,也不是指代码,它**具体**指的是操作系统正在**执行**和管理的东西。 +* 任何程序,任何代码,**只有在执行时才能做事**。 因此,是当有**进程正在运行**时。 +* 该进程可以由您或操作系统**终止**(或“杀死”)。 那时,它停止运行/被执行,并且它可以**不再做事情**。 +* 您计算机上运行的每个应用程序背后都有一些进程,每个正在运行的程序,每个窗口等。并且通常在计算机打开时**同时**运行许多进程。 +* **同一程序**可以有**多个进程**同时运行。 + +如果您检查操作系统中的“任务管理器”或“系统监视器”(或类似工具),您将能够看到许多正在运行的进程。 + +例如,您可能会看到有多个进程运行同一个浏览器程序(Firefox、Chrome、Edge 等)。 他们通常每个tab运行一个进程,再加上一些其他额外的进程。 + + + +--- + +现在我们知道了术语“进程”和“程序”之间的区别,让我们继续讨论部署。 + +## 启动时运行 + +在大多数情况下,当您创建 Web API 时,您希望它**始终运行**、不间断,以便您的客户端始终可以访问它。 这是当然的,除非您有特定原因希望它仅在某些情况下运行,但大多数时候您希望它不断运行并且**可用**。 + +### 在远程服务器中 + +当您设置远程服务器(云服务器、虚拟机等)时,您可以做的最简单的事情就是手动运行 Uvicorn(或类似的),就像本地开发时一样。 + +它将会在**开发过程中**发挥作用并发挥作用。 + +但是,如果您与服务器的连接丢失,**正在运行的进程**可能会终止。 + +如果服务器重新启动(例如更新后或从云提供商迁移后),您可能**不会注意到它**。 因此,您甚至不知道必须手动重新启动该进程。 所以,你的 API 将一直处于挂掉的状态。 😱 + + +### 启动时自动运行 + +一般来说,您可能希望服务器程序(例如 Uvicorn)在服务器启动时自动启动,并且不需要任何**人为干预**,让进程始终与您的 API 一起运行(例如 Uvicorn 运行您的 FastAPI 应用程序) 。 + +### 单独的程序 + +为了实现这一点,您通常会有一个**单独的程序**来确保您的应用程序在启动时运行。 在许多情况下,它还可以确保其他组件或应用程序也运行,例如数据库。 + +### 启动时运行的示例工具 + +可以完成这项工作的工具的一些示例是: + +* Docker +* Kubernetes +* Docker Compose +* Docker in Swarm Mode +* Systemd +* Supervisor +* 作为其服务的一部分由云提供商内部处理 +* 其他的... + +我将在接下来的章节中为您提供更具体的示例。 + + +## 重新启动 + +与确保应用程序在启动时运行类似,您可能还想确保它在挂掉后**重新启动**。 + +### 我们会犯错误 + +作为人类,我们总是会犯**错误**。 软件几乎*总是*在不同的地方隐藏着**bug**。 🐛 + +作为开发人员,当我们发现这些bug并实现新功能(也可能添加新bug😅)时,我们会不断改进代码。 + +### 自动处理小错误 + +使用 FastAPI 构建 Web API 时,如果我们的代码中存在错误,FastAPI 通常会将其包含到触发错误的单个请求中。 🛡 + +对于该请求,客户端将收到 **500 内部服务器错误**,但应用程序将继续处理下一个请求,而不是完全崩溃。 + +### 更大的错误 - 崩溃 + +尽管如此,在某些情况下,我们编写的一些代码可能会导致整个应用程序崩溃,从而导致 Uvicorn 和 Python 崩溃。 💥 + +尽管如此,您可能不希望应用程序因为某个地方出现错误而保持死机状态,您可能希望它**继续运行**,至少对于未破坏的*路径操作*。 + +### 崩溃后重新启动 + +但在那些严重错误导致正在运行的**进程**崩溃的情况下,您需要一个外部组件来负责**重新启动**进程,至少尝试几次...... + +!!! tip + + ...尽管如果整个应用程序只是**立即崩溃**,那么永远重新启动它可能没有意义。 但在这些情况下,您可能会在开发过程中注意到它,或者至少在部署后立即注意到它。 + + 因此,让我们关注主要情况,在**未来**的某些特定情况下,它可能会完全崩溃,但重新启动它仍然有意义。 + +您可能希望让这个东西作为 **外部组件** 负责重新启动您的应用程序,因为到那时,使用 Uvicorn 和 Python 的同一应用程序已经崩溃了,因此同一应用程序的相同代码中没有东西可以对此做出什么。 + +### 自动重新启动的示例工具 + +在大多数情况下,用于**启动时运行程序**的同一工具也用于处理自动**重新启动**。 + +例如,可以通过以下方式处理: + +* Docker +* Kubernetes +* Docker Compose +* Docker in Swarm mode +* Systemd +* Supervisor +* 作为其服务的一部分由云提供商内部处理 +* 其他的... + +## 复制 - 进程和内存 + +对于 FastAPI 应用程序,使用像 Uvicorn 这样的服务器程序,在**一个进程**中运行一次就可以同时为多个客户端提供服务。 + +但在许多情况下,您会希望同时运行多个工作进程。 + +### 多进程 - Workers + +如果您的客户端数量多于单个进程可以处理的数量(例如,如果虚拟机不是太大),并且服务器的 CPU 中有 **多个核心**,那么您可以让 **多个进程** 运行 同时处理同一个应用程序,并在它们之间分发所有请求。 + +当您运行同一 API 程序的**多个进程**时,它们通常称为 **workers**。 + +### 工作进程和端口 + +还记得文档 [About HTTPS](./https.md){.internal-link target=_blank} 中只有一个进程可以侦听服务器中的端口和 IP 地址的一种组合吗? + +现在仍然是对的。 + +因此,为了能够同时拥有**多个进程**,必须有一个**单个进程侦听端口**,然后以某种方式将通信传输到每个工作进程。 + +### 每个进程的内存 + +现在,当程序将内容加载到内存中时,例如,将机器学习模型加载到变量中,或者将大文件的内容加载到变量中,所有这些都会消耗服务器的一点内存 (RAM) 。 + +多个进程通常**不共享任何内存**。 这意味着每个正在运行的进程都有自己的东西、变量和内存。 如果您的代码消耗了大量内存,**每个进程**将消耗等量的内存。 + +### 服务器内存 + +例如,如果您的代码加载 **1 GB 大小**的机器学习模型,则当您使用 API 运行一个进程时,它将至少消耗 1 GB RAM。 如果您启动 **4 个进程**(4 个工作进程),每个进程将消耗 1 GB RAM。 因此,您的 API 总共将消耗 **4 GB RAM**。 + +如果您的远程服务器或虚拟机只有 3 GB RAM,尝试加载超过 4 GB RAM 将导致问题。 🚨 + + +### 多进程 - 一个例子 + +在此示例中,有一个 **Manager Process** 启动并控制两个 **Worker Processes**。 + +该管理器进程可能是监听 IP 中的 **端口** 的进程。 它将所有通信传输到工作进程。 + +这些工作进程将是运行您的应用程序的进程,它们将执行主要计算以接收 **请求** 并返回 **响应**,并且它们将加载您放入 RAM 中的变量中的任何内容。 + + + +当然,除了您的应用程序之外,同一台机器可能还运行**其他进程**。 + +一个有趣的细节是,随着时间的推移,每个进程使用的 **CPU 百分比可能会发生很大变化,但内存 (RAM) 通常会或多或少保持稳定**。 + +如果您有一个每次执行相当数量的计算的 API,并且您有很多客户端,那么 **CPU 利用率** 可能也会保持稳定(而不是不断快速上升和下降)。 + +### 复制工具和策略示例 + +可以通过多种方法来实现这一目标,我将在接下来的章节中向您详细介绍具体策略,例如在谈论 Docker 和容器时。 + +要考虑的主要限制是必须有一个**单个**组件来处理**公共IP**中的**端口**。 然后它必须有一种方法将通信**传输**到复制的**进程/worker**。 + +以下是一些可能的组合和策略: + +* **Gunicorn** 管理 **Uvicorn workers** + * Gunicorn 将是监听 **IP** 和 **端口** 的 **进程管理器**,复制将通过 **多个 Uvicorn 工作进程** 进行 +* **Uvicorn** 管理 **Uvicorn workers** + * 一个 Uvicorn **进程管理器** 将监听 **IP** 和 **端口**,并且它将启动 **多个 Uvicorn 工作进程** +* **Kubernetes** 和其他分布式 **容器系统** + * **Kubernetes** 层中的某些东西将侦听 **IP** 和 **端口**。 复制将通过拥有**多个容器**,每个容器运行**一个 Uvicorn 进程** +* **云服务** 为您处理此问题 + * 云服务可能**为您处理复制**。 它可能会让您定义 **要运行的进程**,或要使用的 **容器映像**,在任何情况下,它很可能是 **单个 Uvicorn 进程**,并且云服务将负责复制它。 + + + +!!! tip + + 如果这些关于 **容器**、Docker 或 Kubernetes 的内容还没有多大意义,请不要担心。 + + 我将在以后的章节中向您详细介绍容器镜像、Docker、Kubernetes 等:[容器中的 FastAPI - Docker](./docker.md){.internal-link target=_blank}。 + +## 启动之前的步骤 + +在很多情况下,您希望在**启动**应用程序之前执行一些步骤。 + +例如,您可能想要运行**数据库迁移**。 + +但在大多数情况下,您只想执行这些步骤**一次**。 + +因此,在启动应用程序之前,您将需要一个**单个进程**来执行这些**前面的步骤**。 + +而且您必须确保它是运行前面步骤的单个进程, *即使*之后您为应用程序本身启动**多个进程**(多个worker)。 如果这些步骤由**多个进程**运行,它们会通过在**并行**运行来**重复**工作,并且如果这些步骤像数据库迁移一样需要小心处理,它们可能会导致每个进程和其他进程发生冲突。 + +当然,也有一些情况,多次运行前面的步骤也没有问题,这样的话就好办多了。 + +!!! tip + + 另外,请记住,根据您的设置,在某些情况下,您在开始应用程序之前**可能甚至不需要任何先前的步骤**。 + + 在这种情况下,您就不必担心这些。 🤷 + + +### 前面步骤策略的示例 + +这将在**很大程度上取决于您部署系统的方式**,并且可能与您启动程序、处理重启等的方式有关。 + +以下是一些可能的想法: + +* Kubernetes 中的“Init Container”在应用程序容器之前运行 +* 一个 bash 脚本,运行前面的步骤,然后启动您的应用程序 + * 您仍然需要一种方法来启动/重新启动 bash 脚本、检测错误等。 + +!!! tip + + 我将在以后的章节中为您提供使用容器执行此操作的更具体示例:[容器中的 FastAPI - Docker](./docker.md){.internal-link target=_blank}。 + +## 资源利用率 + +您的服务器是一个**资源**,您可以通过您的程序消耗或**利用**CPU 上的计算时间以及可用的 RAM 内存。 + +您想要消耗/利用多少系统资源? 您可能很容易认为“不多”,但实际上,您可能希望在不崩溃的情况下**尽可能多地消耗**。 + +如果您支付了 3 台服务器的费用,但只使用了它们的一点点 RAM 和 CPU,那么您可能**浪费金钱** 💸,并且可能 **浪费服务器电力** 🌎,等等。 + +在这种情况下,最好只拥有 2 台服务器并使用更高比例的资源(CPU、内存、磁盘、网络带宽等)。 + +另一方面,如果您有 2 台服务器,并且正在使用 **100% 的 CPU 和 RAM**,则在某些时候,一个进程会要求更多内存,并且服务器将不得不使用磁盘作为“内存” (这可能会慢数千倍),甚至**崩溃**。 或者一个进程可能需要执行一些计算,并且必须等到 CPU 再次空闲。 + +在这种情况下,最好购买**一台额外的服务器**并在其上运行一些进程,以便它们都有**足够的 RAM 和 CPU 时间**。 + +由于某种原因,您的 API 的使用量也有可能出现**激增**。 也许它像病毒一样传播开来,或者也许其他一些服务或机器人开始使用它。 在这些情况下,您可能需要额外的资源来保证安全。 + +您可以将一个**任意数字**设置为目标,例如,资源利用率**在 50% 到

+ +```console +$ docker build -t myimage . + +---> 100% +``` + +
+ + +!!! tip + 注意最后的 `.`,它相当于`./`,它告诉 Docker 用于构建容器镜像的目录。 + + 在本例中,它是相同的当前目录(`.`)。 + +### 启动 Docker 容器 + +* 根据你的镜像运行容器: + +

tip + Traefik可以与 Docker、Kubernetes 等集成,因此使用它为容器设置和配置 HTTPS 非常容易。 + +或者,HTTPS 可以由云服务商作为其服务之一进行处理(同时仍在容器中运行应用程序)。 + +## 在启动和重新启动时运行 + +通常还有另一个工具负责**启动和运行**你的容器。 + +它可以直接是**Docker**, 或者**Docker Compose**、**Kubernetes**、**云服务**等。 + +在大多数(或所有)情况下,有一个简单的选项可以在启动时运行容器并在失败时重新启动。 例如,在 Docker 中,它是命令行选项 `--restart`。 + +如果不使用容器,让应用程序在启动时运行并重新启动可能会很麻烦且困难。 但在大多数情况下,当**使用容器**时,默认情况下会包含该功能。 ✨ + +## 复制 - 进程数 + +如果你有一个 集群, 比如 **Kubernetes**、Docker Swarm、Nomad 或其他类似的复杂系统来管理多台机器上的分布式容器,那么你可能希望在**集群级别**处理复制**,而不是在每个容器中使用**进程管理器**(如带有Worker的 Gunicorn) 。 + +像 Kubernetes 这样的分布式容器管理系统通常有一些集成的方法来处理**容器的复制**,同时仍然支持传入请求的**负载均衡**。 全部都在**集群级别**。 + +在这些情况下,你可能希望从头开始构建一个 **Docker 镜像**,如[上面所解释](#dockerfile)的那样,安装依赖项并运行 **单个 Uvicorn 进程**,而不是运行 Gunicorn 和 Uvicorn workers这种。 + + +### 负载均衡器 + +使用容器时,通常会有一些组件**监听主端口**。 它可能是处理 **HTTPS** 的 **TLS 终止代理** 或一些类似的工具的另一个容器。 + +由于该组件将接受请求的**负载**并(希望)以**平衡**的方式在worker之间分配该请求,因此它通常也称为**负载均衡器**。 + +!!! tip + 用于 HTTPS **TLS 终止代理** 的相同组件也可能是 **负载均衡器**。 + +当使用容器时,你用来启动和管理容器的同一系统已经具有内部工具来传输来自该**负载均衡器**(也可以是**TLS 终止代理**) 的**网络通信**(例如HTTP请求)到你的应用程序容器。 + +### 一个负载均衡器 - 多个worker容器 + +当使用 **Kubernetes** 或类似的分布式容器管理系统时,使用其内部网络机制将允许单个在主 **端口** 上侦听的 **负载均衡器** 将通信(请求)传输到可能的 **多个** 运行你应用程序的容器。 + +运行你的应用程序的每个容器通常**只有一个进程**(例如,运行 FastAPI 应用程序的 Uvicorn 进程)。 它们都是**相同的容器**,运行相同的东西,但每个容器都有自己的进程、内存等。这样你就可以在 CPU 的**不同核心**, 甚至在**不同的机器**充分利用**并行化(parallelization)**。 + +具有**负载均衡器**的分布式容器系统将**将请求轮流分配**给你的应用程序的每个容器。 因此,每个请求都可以由运行你的应用程序的多个**复制容器**之一来处理。 + +通常,这个**负载均衡器**能够处理发送到集群中的*其他*应用程序的请求(例如发送到不同的域,或在不同的 URL 路径前缀下),并正确地将该通信传输到在集群中运行的*其他*应用程序的对应容器。 + + + + + + +### 每个容器一个进程 + +在这种类型的场景中,你可能希望**每个容器有一个(Uvicorn)进程**,因为你已经在集群级别处理复制。 + +因此,在这种情况下,你**不会**希望拥有像 Gunicorn 和 Uvicorn worker一样的进程管理器,或者 Uvicorn 使用自己的 Uvicorn worker。 你可能希望每个容器(但可能有多个容器)只有一个**单独的 Uvicorn 进程**。 + +在容器内拥有另一个进程管理器(就像使用 Gunicorn 或 Uvicorn 管理 Uvicorn 工作线程一样)只会增加**不必要的复杂性**,而你很可能已经在集群系统中处理这些复杂性了。 + +### 具有多个进程的容器 + +当然,在某些**特殊情况**,你可能希望拥有 **一个容器**,其中包含 **Gunicorn 进程管理器**,并在其中启动多个 **Uvicorn worker进程**。 + +在这些情况下,你可以使用 **官方 Docker 镜像**,其中包含 **Gunicorn** 作为运行多个 **Uvicorn 工作进程** 的进程管理器,以及一些默认设置来根据当前情况调整工作进程数量 自动CPU核心。 我将在下面的 [Gunicorn - Uvicorn 官方 Docker 镜像](#official-docker-image-with-gunicorn-uvicorn) 中告诉你更多相关信息。 + +下面一些什么时候这种做法有意义的示例: + + +#### 一个简单的应用程序 + +如果你的应用程序**足够简单**,你不需要(至少现在不需要)过多地微调进程数量,并且你可以使用自动默认值,那么你可能需要容器中的进程管理器 (使用官方 Docker 镜像),并且你在**单个服务器**而不是集群上运行它。 + +#### Docker Compose + +你可以使用 **Docker Compose** 部署到**单个服务器**(而不是集群),因此你没有一种简单的方法来管理容器的复制(使用 Docker Compose),同时保留共享网络和 **负载均衡**。 + +然后,你可能希望拥有一个**单个容器**,其中有一个**进程管理器**,在其中启动**多个worker进程**。 + +#### Prometheus和其他原因 + +你还可能有**其他原因**,这将使你更容易拥有一个带有**多个进程**的**单个容器**,而不是拥有每个容器中都有**单个进程**的**多个容器**。 + +例如(取决于你的设置)你可以在同一个容器中拥有一些工具,例如 Prometheus exporter,该工具应该有权访问**每个请求**。 + +在这种情况下,如果你有**多个容器**,默认情况下,当 Prometheus 来**读取metrics**时,它每次都会获取**单个容器**的metrics(对于处理该特定请求的容器),而不是获取所有复制容器的**累积metrics**。 + +在这种情况, 这种做法会更加简单:让**一个容器**具有**多个进程**,并在同一个容器上使用本地工具(例如 Prometheus exporter)收集所有内部进程的 Prometheus 指标并公开单个容器上的这些指标。 + +--- + +要点是,这些都**不是**你必须盲目遵循的**一成不变的规则**。 你可以根据这些思路**评估你自己的场景**并决定什么方法是最适合你的的系统,考虑如何管理以下概念: + +* 安全性 - HTTPS +* 启动时运行 +* 重新启动 +* 复制(运行的进程数) +* 内存 +* 开始前的先前步骤 + +## 内存 + +如果你**每个容器运行一个进程**,那么每个容器所消耗的内存或多或少是定义明确的、稳定的且有限的(如果它们是复制的,则不止一个)。 + +然后,你可以在容器管理系统的配置中设置相同的内存限制和要求(例如在 **Kubernetes** 中)。 这样,它将能够在**可用机器**中**复制容器**,同时考虑容器所需的内存量以及集群中机器中的可用内存量。 + +如果你的应用程序很**简单**,这可能**不是问题**,并且你可能不需要指定内存限制。 但是,如果你**使用大量内存**(例如使用**机器学习**模型),则应该检查你消耗了多少内存并调整**每台机器**中运行的**容器数量**(也许可以向集群添加更多机器)。 + +如果你**每个容器运行多个进程**(例如使用官方 Docker 镜像),你必须确保启动的进程数量不会消耗比可用内存**更多的内存**。 + +## 启动之前的步骤和容器 + +如果你使用容器(例如 Docker、Kubernetes),那么你可以使用两种主要方法。 + + +### 多个容器 + +如果你有 **多个容器**,可能每个容器都运行一个 **单个进程**(例如,在 **Kubernetes** 集群中),那么你可能希望有一个 **单独的容器** 执行以下操作: 在单个容器中运行单个进程执行**先前步骤**,即运行复制的worker容器之前。 + +!!!

tip + 域名这部分发生在 HTTPS 之前,由于这一切都依赖于域名和 IP 地址,所以先在这里提一下。 + +### DNS + +现在让我们关注真正的 HTTPS 部分。 + +首先,浏览器将通过 **DNS 服务器** 查询**域名的IP** 是什么,在本例中为 `someapp.example.com`。 + +DNS 服务器会告诉浏览器使用某个特定的 **IP 地址**。 这将是你在 DNS 服务器中为你的服务器配置的公共 IP 地址。 + + + +### TLS 握手开始 + +然后,浏览器将在**端口 443**(HTTPS 端口)上与该 IP 地址进行通信。 + +通信的第一部分只是建立客户端和服务器之间的连接并决定它们将使用的加密密钥等。 + + + +客户端和服务器之间建立 TLS 连接的过程称为 **TLS 握手**。 + +### 带有 SNI 扩展的 TLS + +**服务器中只有一个进程**可以侦听特定 **IP 地址**的特定 **端口**。 可能有其他进程在同一 IP 地址的其他端口上侦听,但每个 IP 地址和端口组合只有一个进程。 + +TLS (HTTPS) 默认使用端口`443`。 这就是我们需要的端口。 + +由于只有一个进程可以监听此端口,因此监听端口的进程将是 **TLS 终止代理**。 + +TLS 终止代理可以访问一个或多个 **TLS 证书**(HTTPS 证书)。 + +使用上面讨论的 **SNI 扩展**,TLS 终止代理将检查应该用于此连接的可用 TLS (HTTPS) 证书,并使用与客户端期望的域名相匹配的证书。 + +在这种情况下,它将使用`someapp.example.com`的证书。 + + + +客户端已经**信任**生成该 TLS 证书的实体(在本例中为 Let's Encrypt,但我们稍后会看到),因此它可以**验证**该证书是否有效。 + +然后,通过使用证书,客户端和 TLS 终止代理 **决定如何加密** **TCP 通信** 的其余部分。 这就完成了 **TLS 握手** 部分。 + +此后,客户端和服务器就拥有了**加密的 TCP 连接**,这就是 TLS 提供的功能。 然后他们可以使用该连接来启动实际的 **HTTP 通信**。 + +这就是 **HTTPS**,它只是 **安全 TLS 连接** 内的普通 **HTTP**,而不是纯粹的(未加密的)TCP 连接。 + +!!! tip + 请注意,通信加密发生在 **TCP 层**,而不是 HTTP 层。 + +### HTTPS 请求 + +现在客户端和服务器(特别是浏览器和 TLS 终止代理)具有 **加密的 TCP 连接**,它们可以开始 **HTTP 通信**。 + +接下来,客户端发送一个 **HTTPS 请求**。 这其实只是一个通过 TLS 加密连接的 HTTP 请求。 + + + +### 解密请求 + +TLS 终止代理将使用协商好的加密算法**解密请求**,并将**(解密的)HTTP 请求**传输到运行应用程序的进程(例如运行 FastAPI 应用的 Uvicorn 进程)。 + + + +### HTTP 响应 + +应用程序将处理请求并向 TLS 终止代理发送**(未加密)HTTP 响应**。 + + + +### HTTPS 响应 + +然后,TLS 终止代理将使用之前协商的加密算法(以`someapp.example.com`的证书开头)对响应进行加密,并将其发送回浏览器。 + +接下来,浏览器将验证响应是否有效和是否使用了正确的加密密钥等。然后它会**解密响应**并处理它。 + + + +客户端(浏览器)将知道响应来自正确的服务器,因为它使用了他们之前使用 **HTTPS 证书** 协商出的加密算法。 + +### 多个应用程序 + +在同一台(或多台)服务器中,可能存在**多个应用程序**,例如其他 API 程序或数据库。 + +只有一个进程可以处理特定的 IP 和端口(在我们的示例中为 TLS 终止代理),但其他应用程序/进程也可以在服务器上运行,只要它们不尝试使用相同的 **公共 IP 和端口的组合**。 + + + +这样,TLS 终止代理就可以为多个应用程序处理**多个域名**的 HTTPS 和证书,然后在每种情况下将请求传输到正确的应用程序。 + +### 证书更新 + +在未来的某个时候,每个证书都会**过期**(大约在获得证书后 3 个月)。 + +然后,会有另一个程序(在某些情况下是另一个程序,在某些情况下可能是同一个 TLS 终止代理)与 Let's Encrypt 通信并更新证书。 + + + +**TLS 证书** **与域名相关联**,而不是与 IP 地址相关联。 + +因此,要更新证书,更新程序需要向权威机构(Let's Encrypt)**证明**它确实**“拥有”并控制该域名**。 + +有多种方法可以做到这一点。 一些流行的方式是: + +* **修改一些DNS记录**。 + * 为此,续订程序需要支持 DNS 提供商的 API,因此,要看你使用的 DNS 提供商是否提供这一功能。 +* **在与域名关联的公共 IP 地址上作为服务器运行**(至少在证书获取过程中)。 + * 正如我们上面所说,只有一个进程可以监听特定的 IP 和端口。 + * 这就是当同一个 TLS 终止代理还负责证书续订过程时它非常有用的原因之一。 + * 否则,你可能需要暂时停止 TLS 终止代理,启动续订程序以获取证书,然后使用 TLS 终止代理配置它们,然后重新启动 TLS 终止代理。 这并不理想,因为你的应用程序在 TLS 终止代理关闭期间将不可用。 + +通过拥有一个**单独的系统来使用 TLS 终止代理来处理 HTTPS**, 而不是直接将 TLS 证书与应用程序服务器一起使用 (例如 Uvicorn),你可以在 +更新证书的过程中同时保持提供服务。 + +## 回顾 + +拥有**HTTPS** 非常重要,并且在大多数情况下相当**关键**。 作为开发人员,你围绕 HTTPS 所做的大部分努力就是**理解这些概念**以及它们的工作原理。 + +一旦你了解了**面向开发人员的 HTTPS** 的基础知识,你就可以轻松组合和配置不同的工具,以帮助你以简单的方式管理一切。 + +在接下来的一些章节中,我将向你展示几个为 **FastAPI** 应用程序设置 **HTTPS** 的具体示例。 🔒 diff --git a/docs/zh/docs/deployment/index.md b/docs/zh/docs/deployment/index.md new file mode 100644 index 000000000..1ec0c5c5b --- /dev/null +++ b/docs/zh/docs/deployment/index.md @@ -0,0 +1,21 @@ +# 部署 + +部署 **FastAPI** 应用程序相对容易。 + +## 部署是什么意思 + +**部署**应用程序意味着执行必要的步骤以使其**可供用户使用**。 + +对于**Web API**来说,通常涉及将上传到**云服务器**中,搭配一个性能和稳定性都不错的**服务器程序**,以便你的**用户**可以高效地**访问**你的应用程序,而不会出现中断或其他问题。 + +这与**开发**阶段形成鲜明对比,在**开发**阶段,你不断更改代码、破坏代码、修复代码, 来回停止和重启服务器等。 + +## 部署策略 + +根据你的使用场景和使用的工具,有多种方法可以实现此目的。 + +你可以使用一些工具自行**部署服务器**,你也可以使用能为你完成部分工作的**云服务**,或其他可能的选项。 + +我将向你展示在部署 **FastAPI** 应用程序时你可能应该记住的一些主要概念(尽管其中大部分适用于任何其他类型的 Web 应用程序)。 + +在接下来的部分中,你将看到更多需要记住的细节以及一些技巧。 ✨ diff --git a/docs/zh/docs/deployment/manually.md b/docs/zh/docs/deployment/manually.md new file mode 100644 index 000000000..15588043f --- /dev/null +++ b/docs/zh/docs/deployment/manually.md @@ -0,0 +1,148 @@ +# 手动运行服务器 - Uvicorn + +在远程服务器计算机上运行 **FastAPI** 应用程序所需的主要东西是 ASGI 服务器程序,例如 **Uvicorn**。 + +有 3 个主要可选方案: + +* Uvicorn:高性能 ASGI 服务器。 +* Hypercorn:与 HTTP/2 和 Trio 等兼容的 ASGI 服务器。 +* Daphne:为 Django Channels 构建的 ASGI 服务器。 + +## 服务器主机和服务器程序 + +关于名称,有一个小细节需要记住。 💡 + +“**服务器**”一词通常用于指远程/云计算机(物理机或虚拟机)以及在该计算机上运行的程序(例如 Uvicorn)。 + +请记住,当您一般读到“服务器”这个名词时,它可能指的是这两者之一。 + +当提到远程主机时,通常将其称为**服务器**,但也称为**机器**(machine)、**VM**(虚拟机)、**节点**。 这些都是指某种类型的远程计算机,通常运行 Linux,您可以在其中运行程序。 + + +## 安装服务器程序 + +您可以使用以下命令安装 ASGI 兼容服务器: + +=== "Uvicorn" + + * Uvicorn,一个快如闪电 ASGI 服务器,基于 uvloop 和 httptools 构建。 + +

+ +这里唯一的新选项是 `--workers` 告诉 Uvicorn 启动 4 个工作进程。 + +您还可以看到它显示了每个进程的 **PID**,父进程(这是 **进程管理器**)的 PID 为`27365`,每个工作进程的 PID 为:`27368`、`27369`, `27370`和`27367`。 + +## 部署概念 + +在这里,您了解了如何使用 **Gunicorn**(或 Uvicorn)管理 **Uvicorn 工作进程**来**并行**应用程序的执行,利用 CPU 中的 **多核**,并 能够满足**更多请求**。 + +从上面的部署概念列表来看,使用worker主要有助于**复制**部分,并对**重新启动**有一点帮助,但您仍然需要照顾其他部分: + +* **安全 - HTTPS** +* **启动时运行** +* ***重新启动*** +* 复制(运行的进程数) +* **内存** +* **启动之前的先前步骤** + +## 容器和 Docker + +在关于 [容器中的 FastAPI - Docker](./docker.md){.internal-link target=_blank} 的下一章中,我将介绍一些可用于处理其他 **部署概念** 的策略。 + +我还将向您展示 **官方 Docker 镜像**,其中包括 **Gunicorn 和 Uvicorn worker** 以及一些对简单情况有用的默认配置。 + +在那里,我还将向您展示如何 **从头开始构建自己的镜像** 以运行单个 Uvicorn 进程(没有 Gunicorn)。 这是一个简单的过程,并且可能是您在使用像 **Kubernetes** 这样的分布式容器管理系统时想要做的事情。 + +## 回顾 + +您可以使用**Gunicorn**(或Uvicorn)作为Uvicorn工作进程的进程管理器,以利用**多核CPU**,**并行运行多个进程**。 + +如果您要设置**自己的部署系统**,同时自己处理其他部署概念,则可以使用这些工具和想法。 + +请查看下一章,了解带有容器(例如 Docker 和 Kubernetes)的 **FastAPI**。 您将看到这些工具也有简单的方法来解决其他**部署概念**。 ✨ diff --git a/docs/zh/docs/deployment/versions.md b/docs/zh/docs/deployment/versions.md new file mode 100644 index 000000000..75b870139 --- /dev/null +++ b/docs/zh/docs/deployment/versions.md @@ -0,0 +1,87 @@ +# 关于 FastAPI 版本 + +**FastAPI** 已在许多应用程序和系统的生产环境中使用。 并且测试覆盖率保持在100%。 但其开发进度仍在快速推进。 + +经常添加新功能,定期修复错误,并且代码仍在持续改进。 + +这就是为什么当前版本仍然是`0.x.x`,这反映出每个版本都可能有Breaking changes。 这遵循语义版本控制的约定。 + +你现在就可以使用 **FastAPI** 创建生产环境应用程序(你可能已经这样做了一段时间),你只需确保使用的版本可以与其余代码正确配合即可。 + +## 固定你的 `fastapi` 版本 + +你应该做的第一件事是将你正在使用的 **FastAPI** 版本“固定”到你知道适用于你的应用程序的特定最新版本。 + +例如,假设你在应用程序中使用版本`0.45.0`。 + +如果你使用`requirements.txt`文件,你可以使用以下命令指定版本: + +````txt +fastapi==0.45.0 +```` + +这意味着你将使用版本`0.45.0`。 + +或者你也可以将其固定为: + +````txt +fastapi>=0.45.0,<0.46.0 +```` + +这意味着你将使用`0.45.0`或更高版本,但低于`0.46.0`,例如,版本`0.45.2`仍会被接受。 + +如果你使用任何其他工具来管理你的安装,例如 Poetry、Pipenv 或其他工具,它们都有一种定义包的特定版本的方法。 + +## 可用版本 + +你可以在[发行说明](../release-notes.md){.internal-link target=_blank}中查看可用版本(例如查看当前最新版本)。 + +## 关于版本 + +遵循语义版本控制约定,任何低于`1.0.0`的版本都可能会添加 breaking changes。 + +FastAPI 还遵循这样的约定:任何`PATCH`版本更改都是为了bug修复和non-breaking changes。 + +!!! tip + "PATCH"是最后一个数字,例如,在`0.2.3`中,PATCH版本是`3`。 + +因此,你应该能够固定到如下版本: + +```txt +fastapi>=0.45.0,<0.46.0 +``` + +"MINOR"版本中会添加breaking changes和新功能。 + +!!! tip + "MINOR"是中间的数字,例如,在`0.2.3`中,MINOR版本是`2`。 + +## 升级FastAPI版本 + +你应该为你的应用程序添加测试。 + +使用 **FastAPI** 编写测试非常简单(感谢 Starlette),请参考文档:[测试](../tutorial/testing.md){.internal-link target=_blank} + +添加测试后,你可以将 **FastAPI** 版本升级到更新版本,并通过运行测试来确保所有代码都能正常工作。 + +如果一切正常,或者在进行必要的更改之后,并且所有测试都通过了,那么你可以将`fastapi`固定到新的版本。 + +## 关于Starlette + +你不应该固定`starlette`的版本。 + +不同版本的 **FastAPI** 将使用特定的较新版本的 Starlette。 + +因此,**FastAPI** 自己可以使用正确的 Starlette 版本。 + +## 关于 Pydantic + +Pydantic 包含针对 **FastAPI** 的测试及其自己的测试,因此 Pydantic 的新版本(`1.0.0`以上)始终与 FastAPI 兼容。 + +你可以将 Pydantic 固定到适合你的`1.0.0`以上和`2.0.0`以下的任何版本。 + +例如: + +````txt +pydantic>=1.2.0,<2.0.0 +```` diff --git a/docs/zh/docs/help-fastapi.md b/docs/zh/docs/help-fastapi.md index 2a99950e3..9b70d115a 100644 --- a/docs/zh/docs/help-fastapi.md +++ b/docs/zh/docs/help-fastapi.md @@ -114,8 +114,6 @@ 聊天室仅供闲聊。 -我们之前还使用过 Gitter chat,但它不支持频道等高级功能,聊天也比较麻烦,所以现在推荐使用 Discord。 - ### 别在聊天室里提问 注意,聊天室更倾向于“闲聊”,经常有人会提出一些笼统得让人难以回答的问题,所以在这里提问一般没人回答。 diff --git a/docs/zh/docs/history-design-future.md b/docs/zh/docs/history-design-future.md new file mode 100644 index 000000000..56a15d003 --- /dev/null +++ b/docs/zh/docs/history-design-future.md @@ -0,0 +1,78 @@ +# 历史、设计、未来 + +不久前,曾有 **FastAPI** 用户问过: + +> 这个项目有怎样的历史?好像它只用了几周就从默默无闻变得众所周知…… + +在此,我们简单回顾一下 **FastAPI** 的历史。 + +## 备选方案 + +有那么几年,我曾领导数个开发团队为诸多复杂需求创建各种 API,这些需求包括机器学习、分布系统、异步任务、NoSQL 数据库等领域。 + +作为工作的一部分,我需要调研很多备选方案、还要测试并且使用这些备选方案。 + +**FastAPI** 其实只是延续了这些前辈的历史。 + +正如[备选方案](alternatives.md){.internal-link target=_blank}一章所述: + +

+ +## 调研 + +通过使用之前所有的备选方案,我有机会从它们之中学到了很多东西,获取了很多想法,并以我和我的开发团队能想到的最好方式把这些思路整合成一体。 + +例如,大家都清楚,在理想状态下,它应该基于标准的 Python 类型提示。 + +而且,最好的方式是使用现有的标准。 + +因此,甚至在开发 **FastAPI** 前,我就花了几个月的时间研究 OpenAPI、JSON
