# -*- coding: utf-8 -*-
"""
This module simplifies the process of obtaining an authenticated session for mobile steam websites.
After authentication is complete, a :class:`requests.Session` is created containing the auth and mobile specific cookies.
The session can be used to access ``steamcommunity.com``, ``store.steampowered.com``, and ``help.steampowered.com``.
The main purpose of a mobile session, is to access the mobile trade confirmations page and to easily access the
ITwoFactorService api, but can also used to access all 'normal' steam pages.
.. warning::
A web session may expire randomly, or when you login from different IP address.
Some pages will return status code `401` when that happens.
Keep in mind if you are trying to write robust code.
Example usage:
.. code:: python
import steam.mobileauth as ma
user = ma.WebAuth('username', 'password')
try:
user.login()
except wa.CaptchaRequired:
print user.captcha_url
# ask a human to solve captcha
user.login(captcha='ABC123')
except wa.EmailCodeRequired:
user.login(email_code='ZXC123')
except wa.TwoFactorCodeRequired:
user.login(twofactor_code='ZXC123')
user.session.get('https://store.steampowered.com/account/history/')
# OR
session = user.login()
session.get('https://store.steampowered.com/account/history')
Alternatively, if Steam Guard is not enabled on the account:
.. code:: python
try:
session = wa.WebAuth('username', 'password').login()
except wa.HTTPError:
pass
The :class:`MobileAuth` instance should be discarded once a session is obtained
as it is not reusable.
