Return 响应语句未返回任何响应

Question

我正在创建注销视图以使用 simplejwt 从我的 django restframework 注销。没有直接注销的方法，因此只能将刷新令牌列入黑名单。

那些打印语句按预期工作，所以它确实将标记列入黑名单，但 return 语句没有 return 任何东西，为什么会这样，我如何 return 回应？我我猜保存功能没有 return 任何东西，是真的吗？

class LogoutSerializer(serializers.Serializer):
    refresh = serializers.CharField()

    def validate(self, attrs):
        self.token = attrs['refresh']
        return attrs

    def save(self, **kwargs):
        try:
            RefreshToken(self.token).blacklist()
            print('done')
            return Response({'msg':'token has been blacklisted'})
       

        except TokenError:
            print('not done')
            return Response({'msg':'token is expired or blacklisted'})

views.py

class LogoutAPIView(APIView):
    serializer_class = LogoutSerializer
    permission_classes = [IsAuthenticated]

    def post(self, request):
        serializer = self.serializer_class(data = request.data)
        serializer.is_valid(raise_exception = True)
        serializer.save()

        return Response(status = status.HTTP_204_NO_CONTENT)

Answer 1

def post(self, request):
    serializer = self.serializer_class(data = request.data)
    serializer.is_valid(raise_exception = True)
    serializer.save()

    return Response(status = status.HTTP_204_NO_CONTENT) # this is the response that you're actually returning to the client.

如果您想 return 序列化程序中的响应，您可以这样做：

class LogoutSerializer(serializers.Serializer):
    refresh = serializers.CharField()

    def validate(self, attrs):
        self.token = attrs['refresh']
        return attrs

    def save(self, **kwargs):
        RefreshToken(self.token).blacklist()

然后：

def post(self, request):
    serializer = self.serializer_class(data = request.data)
    serializer.is_valid(raise_exception = True)
    try:
        serializer.save()
        return Response({'msg':'token has been blacklisted'})
    except TokenError:
        return Response({'msg':'token is expired or blacklisted'})

Return 响应语句未返回任何响应

Return response statement is not returning any response
