Python CSRF豁免故障-APIView CSRF django rest框架

我有以下代码：

问题是，当我尝试访问用户登录/I时出现错误： “CSRF失败：未设置CSRF cookie。”

我能做什么

我正在使用django rest框架

urls.py:

url(r'^user-login/$', 
    csrf_exempt(LoginView.as_view()),
    name='user-login'),

views.py:

class LoginView(APIView):
"""
List all snippets, or create a new snippet.
"""
def get(self, request, format=None):
    startups = Startup.objects.all()
    serializer = StartupSerializer(startups, many=True)
    return Response(serializer.data)

def post(self, request, format=None):
    profile = request.POST

    if ('user_name' not in profile or 'email_address' not in profile or 'oauth_secret' not in profile):
        return Response(
            {'error': 'No data'},
            status=status.HTTP_400_BAD_REQUEST)

    username = 'l' + profile['user_name']
    email_address = profile['email_address']
    oauth_secret = profile['oauth_secret']
    password = oauth_secret

我假设您使用django rest框架。此后端执行以下操作：

您可以通过以下方式避免这种情况：

from rest_framework.authentication import SessionAuthentication

class UnsafeSessionAuthentication(SessionAuthentication):

    def authenticate(self, request):
        http_request = request._request
        user = getattr(http_request, 'user', None)

        if not user or not user.is_active:
           return None

        return (user, None)

并将其设置为在您的视图中

class UnsafeLogin(APIView):
    permission_classes = (AllowAny,) #maybe not needed in your case
    authentication_classes = (UnsafeSessionAuthentication,)

    def post(self, request, *args, **kwargs):

        username = request.DATA.get("u");
        password = request.DATA.get("p");

        user = authenticate(username=username, password=password)
        if user is not None:
           login(request, user)

        return redirect("/")

实际上，禁用SessionAuthentication内部csrf检查的更好方法是：

from rest_framework.authentication import SessionAuthentication as OriginalSessionAuthentication

class SessionAuthentication(OriginalSessionAuthentication):
    def enforce_csrf(self, request):
        return

解决此问题的最简单方法是：

因此，在drf中有两种身份验证方法

基底动脉造影

会话身份验证（默认）

SessionAuthentication具有强制csrf检查，但BasicAuthentication没有。 因此，在我看来，我的方法是使用基本身份验证，而不是会话身份验证

from rest_framework.authentication import BasicAuthentication

class UserLogin(generics.CreateAPIView):
    permission_classes = (permissions.AllowAny,)
    serializer_class = UserSerializer
    authentication_classes = (BasicAuthentication,)

    def post(self, request, *args, **kwargs):
        return Response({})

---

最好是让enforce_csrf检查什么都不做：

from rest_framework.authentication import SessionAuthentication

class UnsafeSessionAuthentication(SessionAuthentication):

    def enforce_csrf(self, *args, **kwargs):
        '''
        Bypass the CSRF checks altogether
        '''
        pass

否则，如果上游authenticate（）方法发生更改，将来可能会出现问题。而且，让支票不做任何事情要简单得多：-）
