Python 需要在Django Rest框架中使用AnonymousUser登录

我有一个viewsetapi，它可以获得用户的身份验证通知，但我得到了错误。请看一看

视图集：

from api.notifications.models import Notification 
from rest_framework.generics import ( ListAPIView )
from api.notifications.serializers import ( NotificationListSerializer )
from api.pagination import NewFeedPagination
from rest_framework.permissions import AllowAny
from api.permissions import IsOwnerOrReadOnly

class NotificationListAPIView(ListAPIView):
    permission_classes = [AllowAny]
    serializer_class = NotificationListSerializer
    ordering_fields = 'date'

    def get_queryset(self, *args, **kwargs):
        queryset_list = Notification.objects.filter(to_user=self.request.user)
        return queryset_list

登录并访问URL时，它已成功。但它没有登录，出现了错误：

int（）参数必须是字符串或数字，而不是“AnonymousUser”

。如何设置AnonymousUser，URL将进入登录页面：localhost:8000/admin

Exception Type: TypeError at /api/v1/notifications/
Exception Value: int() argument must be a string or a number, not 'AnonymousUser'

正如你的错误所说：

Exception Value: int() argument must be a string or a number, not 'AnonymousUser'

这意味着要过滤

通知

您正在传递的是完整的用户对象，而不是仅传递id，因此：

改变这一行，这就行了

 16.         queryset_list = Notification.objects.filter(to_user=self.request.user.id)

看起来您尚未在设置中设置DRF。尝试以下操作（或根据需要选择设置）并查看其是否有效：

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ),
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated'
    ]
}

你能把整个回溯错误公布出来吗？比如从哪个文件中，从哪个行号得到这个错误？回溯完成，兄弟！
