Django 自定义中间件 request.user 始终 AnonymousUser

我在用着姜戈2.2 and DRF

在我的应用程序中，根据用户属性，我需要更改request.user给不同的用户。

class CustomMiddleware:
  def __init__(self, get_response):
     self.get_response = get_response

  def __call__(self, request):
     print(request.user)

     response = self.get_response(request)
     return response

The print(request.user)总是给予AnonymousUser对象，但它在视图中提供了经过身份验证的用户。

如何在中间件中获取用户？

中间件层次结构

MIDDLEWARE = [
    'django_hosts.middleware.HostsRequestMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',

    'whitenoise.middleware.WhiteNoiseMiddleware',

    'debug_toolbar.middleware.DebugToolbarMiddleware',
    'silk.middleware.SilkyMiddleware',
    'django_hosts.middleware.HostsResponseMiddleware',

    'oauth2_provider.middleware.OAuth2TokenMiddleware',
    'myapp.middleware.CustomMiddleware',
]

通过使用解决了它oauth2_provider.backends.OAuth2Backend to the AUTHENTICATION_BACKENDS list.

AUTHENTICATION_BACKENDS = (
    'oauth2_provider.backends.OAuth2Backend',
    # Uncomment following if you want to access the admin
    #'django.contrib.auth.backends.ModelBackend'
    '...',
)
