}

## Disable Convert Underscores
The same way as with regular header parameters, when you have underscore characters in the parameter names, they are **automatically converted to hyphens**.
For example, if you have a header parameter `save_data` in the code, the expected HTTP header will be `save-data`, and it will show up like that in the docs.
If for some reason you need to disable this automatic conversion, you can do it as well for Pydantic models for header parameters.
Если клиент попробует отправить **дополнительные заголовки**, то в ответ он получит **ошибку**.
Например, если клиент попытается отправить заголовок `tool` со значением `plumbus`, то в ответ он получит ошибку, сообщающую ему, что header-параметр `tool` не разрешен:
```json
{
"detail": [
{
"type": "extra_forbidden",
"loc": ["header", "tool"],
"msg": "Extra inputs are not permitted",
"input": "plumbus",
}
]
}
```
## Как отключить автоматическое преобразование подчеркиваний
Как и в случае с обычными заголовками, если у вас в именах параметров имеются символы подчеркивания, они **автоматически преобразовываются в дефис**.
Например, если в коде есть header-параметр `save_data`, то ожидаемый HTTP-заголовок будет `save-data` и именно так он будет отображаться в документации.
Если по каким-то причинам вам нужно отключить данное автоматическое преобразование, это можно сделать и для Pydantic-моделей для header-параметров.
Перед тем как устанавливать для параметра `convert_underscores` значение `False`, имейте в виду, что некоторые HTTP-прокси и серверы не разрешают использовать заголовки с символами подчеркивания.
///
## Резюме
Вы можете использовать **Pydantic-модели** для объявления **header-параметров** в **FastAPI**. 😎

这在大多数情况下都能正常运行。😎
通过添加`standard`，Uvicorn 将安装并使用一些推荐的额外依赖项。
例如，您可以使用该命令在容器、服务器等环境中启动您的 **FastAPI** 应用。
其中包括`uvloop`，它是`asyncio`的高性能替代品，它提供了巨大的并发性能提升。
## ASGI 服务器
///
让我们深入了解一些细节。

FastAPI 使用了一种用于构建 Python Web 框架和服务器的标准，称为 <abbrtitle="Asynchronous Server Gateway Interface，异步服务器网关接口">ASGI</abbr>。FastAPI 本质上是一个 ASGI Web 框架。
