paginations.py文件：自定以加密分页类

from rest_framework.pagination import CursorPagination
class CarCursorPagination(CursorPagination):
    # 默认一页的条数
    page_size = 3
    
    # 用户可以自定义选择一页的条数，但最多显示max_page_size设置的条数
    page_size_query_param = 'page_size'
    max_page_size = 5
    
    # 默认排序规则：按pk从小到大排序，-pk表示从大到小排序
    ordering = 'pk'

view.py文件：

from rest_framework.viewsets import ModelViewSet
from . import models, serializer
from .paginations import CarCursorPagin
from rest_framework.filters import OrderingFilter
class CarModelViewSet(ModelViewSet):
    queryset = models.Car.objects.filter(is_delete=False)
    serializer_class = serializer.CarModelSerializer
    pagination_class = CarCursorPagination
    # filter_backends = [OrderingFilter]

总结：

1.采用默认排序访问，url链接：car/?cursor=加密串

2.结合视图类实现OrderingFilter自定义排序访问，url链接：car/?cursor=加密串&ordering=排序字段
