如何使用python-social-auth在代碼中通過Access Token進行身份驗證

Question

我有一個REST API，我需要通過Facebook Login API對用戶進行身份驗證。 應該在移動應用程序中獲取訪問令牌（我猜），然后發送到服務器。 所以我在舊教程中找到了一些代碼，但我無法使其工作。 這是代碼：

from social.apps.django_app.utils import strategy
from django.contrib.auth import login
from django.views.decorators.csrf import csrf_exempt
from rest_framework.decorators import api_view, permission_classes
from rest_framework import permissions, status
from django.http import HttpResponse as Response


@strategy()
def auth_by_token(request, backend):
    user=request.user
    user = backend.do_auth(
        access_token=request.DATA.get('access_token'),
        user=user.is_authenticated() and user or None
        )
    if user and user.is_active:
        return user
    else:
        return None



@csrf_exempt
@api_view(['POST'])
@permission_classes((permissions.AllowAny,))
def social_register(request):
    auth_token = request.DATA.get('access_token', None)
    backend = request.DATA.get('backend', None)
    if auth_token and backend:
        try:
            user = auth_by_token(request, backend)
        except Exception, err:
            return Response(str(err), status=400)
        if user:
            login(request, user)
            return Response("User logged in", status=status.HTTP_200_OK)
        else:
            return Response("Bad Credentials", status=403)
    else:
        return Response("Bad request", status=400)

當我嘗試使用參數發送POST請求時，我收到此錯誤：

'unicode' object has no attribute 'do_auth'

我在官方文檔中找到了一個例子，它使用@psa('social:complete')裝飾器：

from django.contrib.auth import login

from social.apps.django_app.utils import psa

# Define an URL entry to point to this view, call it passing the
# access_token parameter like ?access_token=<token>. The URL entry must
# contain the backend, like this:
#
#   url(r'^register-by-token/(?P<backend>[^/]+)/$',
#       'register_by_access_token')

@psa('social:complete')
def register_by_access_token(request, backend):
    # This view expects an access_token GET parameter, if it's needed,
    # request.backend and request.strategy will be loaded with the current
    # backend and strategy.
    token = request.GET.get('access_token')
    user = backend.do_auth(request.GET.get('access_token'))
    if user:
        login(request, user)
        return 'OK'
    else:
        return 'ERROR'

但是如果我需要在請求體中傳遞后端名稱呢？

Answer 1

它應該是request.backend.do_auth(request.GET.get('access_token')) 。

我已使用正確的代碼更新了文檔 http://psa.matiasaguirre.net/docs/use_cases.html#signup-by-oauth-access-token https://python-social-auth.readthedocs.io/en /latest/use_cases.html#signup-by-oauth-access-token 。

您現在可以使用此庫https://github.com/ ，使用來自任何python-social-auth后端（Facebook，Google，Github等）的持有令牌/第三方訪問令牌，針對您的django-rest-framework對您的用戶進行身份驗證PhilipGarnero / Django的休息框架，社會的oauth2
