分页代码

from rest_framework.pagination import  PageNumberPagination,LimitOffsetPagination,CursorPagination
class MyPagination(PageNumberPagination):
    # 分页  http://127.0.0.1:8000/pageview/?page=2
    page_size = 1
    max_page_size = 100
    # page_size_query_param = 'size'
    page_query_param = 'page'

class MyLimitPagination(LimitOffsetPagination):
    # http://127.0.0.1:8000/pageview2/?offset=1&limit=1
    default_limit=2
    limit_query_param = 'limit'
    offset_query_param = 'offset'
    max_limit = 100


class MyCursorPagination(CursorPagination):
    # 加密分页 http://127.0.0.1:8000/pageview2/?cursor=Ao23Jje8d2
    cursor_query_param = 'cursor'
    ordering = '-id'
    page_size = 2
    # page_size_query_param = 'size'
    max_page_size = 100

视图代码。 序列化代码相同，序列化实例instance参数值变化。

class PageView(APIView):
    def get(self, request, *args, **kwargs):
        roles=Role.objects.all()
        # ser=PageSerializer(instance=roles,many=True)
        # return json.dumps(ser.data)
        # return Response(ser.data)
        pg=MyPagination()
        pager_roles=pg.paginate_queryset(queryset=roles,request=request,view=self)
        ser=PageSerializer(instance=pager_roles,many=True)

        # return Response(ser.data)
        return pg.get_paginated_response(ser.data)
