基于 Django 类的视图中的身份验证用户

Question

我正在尝试重构我的 django 项目。 因此我想重构：

    @api_view([GET, POST])
    @permission_classes((IsAuthenticated, VehiclePermissions, ))
    def inactive_vehicle_view(request):

        if request.method == "GET":
            con = CBaseUtil.get_prod_instance()
            vehicle_bo = VehicleBO()
            dongle_dao = OBDDongleDAO(con)

            since_days = int(request.GET.get("since", 28))

            vehicles = vehicle_bo.find_vehicles_by_user_context(request.user.details)

            return Response(vehicles, status=status_code, headers=get_headers(request))

到这样的基于类的视图：

class InactiveVehicleView(View):

    @authentication_classes((BasicAuthentication, WebsiteAuthentication))
    @permission_classes((IsAuthenticated, VehiclePermissions, ))
    def dispatch(self, *args, **kwargs):
        return super(InactiveVehicleView, self).dispatch(*args, **kwargs)

    def get(self, request):
        con = CBaseUtil.get_prod_instance()
        vehicle_bo = VehicleBO()
        dongle_dao = OBDDongleDAO(con)

        since_days = int(request.GET.get("since", 28))

        vehicles = vehicle_bo.find_vehicles_by_user_context(request.user.details)

        return Response(vehicles, status=status_code, headers=get_headers(request))

我面临的问题是我无法像在旧版本中那样通过 request.user.details 获取用户详细信息，因为 WSGI-Request 不包含属性用户。我想我对装饰器做错了，但我想不通。

仅供参考，视图被映射到这样的网址中：

url(r'^vehicles/inactive/?$', InactiveVehicleView.as_view())

有人知道我在身份验证和/或装饰器方面做错了什么吗？

根据Django Rest Framework Authentication Docs，您的视图应该继承APIView，并将authentication_classes和permission_classes设置为属性，而不是使用装饰器。

from rest_framework.views import APIView

class InactiveVehicleView(APIView):

    authentication_classes = (BasicAuthentication, WebsiteAuthentication)
    permission_classes = (IsAuthenticated, VehiclePermissions)

    def get(self, request):
        ...
