我使用 ModelViewSet 创建了一个 Django rest api。在暂存中部署，现在在生产中。生产工作正常，但暂存有一些不正确的“下一个”网址。

查看两个图像中的键“next”，第一个图像是暂存响应，第二个是生产响应。在暂存下一个键中，“nub.staging.scoretrends.com”出现两次。两个环境中使用相同的代码。工作在本地主机中也很好。是什么让它发生了这样的事情？ModelViewSet 如下所示。

class EntityDetail(viewsets.ModelViewSet):
    """
    Retrieve a spider.
    """
    queryset = Entity.objects.all()
    serializer_class = EntitySerializer
    filter_backends = (filters.DjangoFilterBackend, filters.OrderingFilter)
    filter_class = EntityFilter
    filter_fields = ('name', 'entity_type', 'gender', 'active', 'verified', 'date_created', 'date_modified')
    ordering_fields = ('name', 'date_created', 'date_modified')

    def get_queryset(self):
        queryset = Entity.objects.all()
        name = self.request.query_params.get('name', None)
        industry = self.request.query_params.get('industry', None)
        entity_types = self.request.query_params.get('entity_types', None)
        if name:
          queryset = Entity.objects.filter(name__icontains=name)
        if industry:
          queryset = Entity.objects.filter(meta__primary_industry__iexact=industry)
        if entity_types:
          entity_types = [int(id) for id in entity_types.split(',')]
          queryset = queryset.filter(entity_type__in=entity_types)
        return queryset

    def list(self, request, *args, **kwargs):
        queryset = self.filter_queryset(self.get_queryset())
        if request.query_params.get('nopaginate') is None:
          page = self.paginate_queryset(queryset)
          if page is not None:
            serializer = EntitySerializer(page, many=True)
            return self.get_paginated_response(serializer.data)
        serializer = EntitySerializer(queryset, many=True)
        return Response(serializer.data)

   def update(self, request, *args, **kwargs):
        instance = self.get_object()
        serializer = EntitySerializer(instance, data=request.data, partial=True)
        serializer.is_valid(raise_exception=True)
        serializer.save(entity_id=instance.pk, **serializer.validated_data)
        return Response(serializer.data)

   def partial_update(self, request, *args, **kwargs):
       kwargs['partial'] = True
       return self.update(request, *args, **kwargs)

这是我使用过的 django rest 配置

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 20,
    'DEFAULT_FILTER_BACKENDS': ('rest_framework.filters.DjangoFilterBackend',),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    )
}
