我正在使用django-rest-knox，当我使用knox_views.LogoutAllView.as_view()注销时，它给了我这个错误：

"detail": "Authentication credentials were not provided."

注意：我使用的是自定义用户模型（AbstarctUser和BaseUserManager）
下面是serializers.py：

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username', 'email','birth_date','first_name','last_name')

# there is a registerserializer too

class LoginSerializer(serializers.Serializer):
    email = serializers.EmailField()
    password = serializers.CharField()

    def validate(self, data):
        user = authenticate(**data)
        if user and user.is_active:
            return user
        raise serializers.ValidationError("Incorrect Credentials")

下面是views.py：

class LoginView(generics.GenericAPIView):
    serializer_class = LoginSerializer

    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user= serializer.validated_data
        return Response({
            "user": UserSerializer(user, context=self.get_serializer_context()).data,
            "token": AuthToken.objects.create(user)[1]
        })

class RegisterAPI(generics.GenericAPIView):
    serializer_class = RegisterSerializer

    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.save()
        return Response({
        "user": UserSerializer(user, context=self.get_serializer_context()).data,
        "token": AuthToken.objects.create(user)[1]
        })
