在 django GET 中使用查询字符串

Question

我在 django rest 框架中有一个 GET 请求，它使用 kwargs 获取数据。

class FetchUser(APIView):

    def get(self, request, **kwargs):
        try:
            email = kwargs.get('email')
            user = User.objects.get(email=email)
            return Response(UserSerializer(user).data, status=status.HTTP_200_OK)
        except(KeyError, User.DoesNotExist) as e:
            return Response(str(e), status=status.HTTP_404_NOT_FOUND)

你可以做类似的事情 -

def get_queryset(self):
    cityId = self.request.GET.get('city')
    # this reads query param
    if cityId is None:
        queryset = branch.objects.all()
        # queryset = branch.objects.none()
    else:
        queryset = branch.objects.filter(city=cityId)
    return queryset
