使用AngularJS和Django REST Framework进行Facebook验证

我正在开发一个SPA应用程序与 AngularJS使用 Django后端的服务器。我从SPA与服务器通信的方式是与 django-rest-framework.所以现在我想使用Facebook(谷歌和Twitter的认证)，我阅读了很多关于这个主题，发现 OAuth.io这是在客户端上的验证SPA侧和 python-social-auth这是做同样的事，但在服务器端。

所以目前我只有客户端auth，我的应用程序连接到Facebook(与OAuth.io)，并成功登录。这个过程返回access_token，然后我向我的API发出请求，它必须登录此用户或通过给定令牌为此用户创建帐户，这部分不工作。所以我不知道我错了，也许因为没有一个完整的教程使用python-social-auth，所以也许我错过了一些东西或..我不知道。

所以一些代码这是我有：

在SPA端：这是与OAuth.io的连接，并且正在工作，因为我获得访问令牌。然后我必须向我的休息API发出请求。后端是’facebook’，’google’或’twitter’

OAuth.initialize('my-auth-code-for-oauthio');
OAuth.popup(backend,function(error,result) {
    //handle error with error
    //use result.access_token in your API request

    var token = 'Token ' + result.access_token;
    var loginPromise = $http({
         method:'POST',url: 'api-token/login/' + backend + '/',headers: {'Authorization': token}});

         loginPromise.success(function () {
             console.log('Succeess');
         });
         loginPromise.error(function (result) {
             console.log('error');
         });
});

在我的settings.py中的服务器上我添加了社交插件到已安装的应用程序，模板上下文预处理器，一些auth后端，这是我的文件：

INSTALLED_APPS = (
    'django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions',...,'rest_framework','rest_framework.authtoken','api','social.apps.django_app.default','social'
)
TEMPLATE_CONTEXT_PROCESSORS = ("django.contrib.auth.context_processors.auth","django.core.context_processors.debug","django.core.context_processors.i18n","django.core.context_processors.media","django.core.context_processors.static","django.core.context_processors.request","django.contrib.messages.context_processors.messages",'social.apps.django_app.context_processors.backends','social.apps.django_app.context_processors.login_redirect',)

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',)
}

SOCIAL_AUTH_FACEBOOK_KEY = 'key'
SOCIAL_AUTH_FACEBOOK_SECRET = 'secret'
SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']

AUTHENTICATION_BACKENDS = (
      'social.backends.open_id.OpenIdAuth','social.backends.facebook.FacebookOAuth2','social.backends.facebook.FacebookAppOAuth','social.backends.google.GoogleOpenId','social.backends.google.GoogleOAuth2','social.backends.google.GoogleOAuth','social.backends.twitter.TwitterOAuth','django.contrib.auth.backends.ModelBackend',)

在我的views.py的API我有以下(我发现它here)：

from django.contrib.auth.models import User,Group
from rest_framework import viewsets,generics
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import authentication,permissions,parsers,renderers
from rest_framework.authtoken.serializers import AuthTokenSerializer
from rest_framework.decorators import api_view,throttle_classes
from social.apps.django_app.utils import strategy
from rest_framework.permissions import IsAuthenticated,IsAuthenticatedOrReadOnly

from django.contrib.auth import get_user_model
from django.db.models.signals import post_save
from django.dispatch import receiver
from rest_framework.authtoken.models import Token

class ObtainAuthToken(APIView):
    throttle_classes = ()
    permission_classes = ()
    parser_classes = (parsers.FormParser,parsers.MultiPartParser,parsers.JSONParser,)
    renderer_classes = (renderers.JSONRenderer,)
    serializer_class = AuthTokenSerializer
    model = Token

    # Accept backend as a parameter and 'auth' for a login / pass
    def post(self,request,backend):
        serializer = self.serializer_class(data=request.DATA)

        if backend == 'auth':
            if serializer.is_valid():
                token,created = Token.objects.get_or_create(user=serializer.object['user'])
                return Response({'token': token.key})
            return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)

        else:
            # Here we call PSA to authenticate like we would if we used PSA on server side.
            user = register_by_access_token(request,backend)

            # If user is active we get or create the REST token and send it back with user data
            if user and user.is_active:
                token,created = Token.objects.get_or_create(user=user)
                return Response({'id': user.id,'name': user.username,'userRole': 'user','token': token.key})

@strategy()
def register_by_access_token(request,backend):
    backend = request.strategy.backend
    user = request.user
    user = backend._do_auth(
        access_token=request.GET.get('access_token'),user=user.is_authenticated() and user or None
    )
    return user

最后我在urls.py中有这些路由：

...
url(r'^api-auth/',include('rest_framework.urls',namespace='rest_framework')),url(r'^api-token-auth/','rest_framework.authtoken.views.obtain_auth_token'),url(r'^api-token/login/(?P<backend>[^/]+)/$',views.ObtainAuthToken.as_view()),url(r'^register/(?P<backend>[^/]+)/',views.register_by_access_token),...

每次当我尝试做auth，OAuth.io是工作和rqest到api返回

detail: “Invalid token”

我认为我错过了在配置python-social-auth的东西，或者我做错了一切。所以我会很高兴，如果任何人有一些想法，并希望帮助:)

authentication_classes = ()

Authorization: Token yourAccessToken

'DjangoStrategy' object has no attribute 'backend'

backend = request.strategy.backend

uri = ''
strategy = load_strategy(request)
backend = load_backend(strategy,backend,uri)
