使用文档请参考：https://python-social-auth.readthedocs.io/en/latest/configuration/django.html

Installing

pip install social-auth-app-django

Register the application

Add the application to INSTALLED_APPS setting

INSTALLED_APPS = (
    ...
    'social_django',
    ...
)

Database

you need to sync the database to create needed models once you added social_django to your installed apps:

./manage.py migrate

Authentication backends

Add desired authentication backends to Django’s AUTHENTICATION_BACKENDS setting:

AUTHENTICATION_BACKENDS = (
    'social_core.backends.weibo.WeiboOAuth2',
    'social_core.backends.qq.QQOAuth2',
    'social_core.backends.weixin.WeixinOAuth2',
    ...
    'django.contrib.auth.backends.ModelBackend',
)

URLs entries

Add URLs entries:

urlpatterns = patterns('',
    ...
    url('', include('social_django.urls', namespace='social'))
    ...
)

Template Context Processors

There’s a context processor that will add backends and associations data to template context:

TEMPLATES = [
    {
        ...
        'OPTIONS': {
            ...
            'context_processors': [
                ...
                'social_django.context_processors.backends',
                'social_django.context_processors.login_redirect',
                ...
            ]
        }
    }
]

Keys and secrets

• Set up needed OAuth keys (see OAuth section for details):

  SOCIAL_AUTH_WEIBO_KEY = '237999617'
  SOCIAL_AUTH_WEIBO_SECRET = '2v652654d62f5dv66586fdd6456ddd5fd'
  
  SOCIAL_AUTH_QQ_KEY = 'foobar'
  SOCIAL_AUTH_QQ_SECRET = 'bazqux'
  
  SOCIAL_AUTH_WEIXIN_KEY = 'foobar'
  SOCIAL_AUTH_WEIXIN_SECRET = 'bazqux'

URLs options

# 登录成功后的重定向url
SOCIAL_AUTH_LOGIN_REDIRECT_URL = '/index/'

重写返回体逻辑

向返回体中添加name cookie和token cookie

social_core.actions.py

def do_complete(backend, login, user=None, redirect_name='next', *args, **kwargs):
    ...
    response = backend.strategy.redirect(url)
    payload = jwt_payload_hander(user)
    response.set_cookie("name", user.name if user.name else user.username, max_age = 24*3600)
    response.set_cookie("token", jwt_encode_handler(payload))
    return response
