看第N页，每页显示N条数据

from rest_framework.response import Response
from rest_framework.pagination import PageNumberPagination

class MyPageNumberPagination(PageNumberPagination):
    page_size = 2
    page_size_query_param = 'size'
    max_page_size = 3

    page_query_param = 'pager'

class Pager1View(APIView):
    def get(self, request, *args, **kwargs):
        # 获取所有数据
        roles = models.Role.objects.all()

        # 创建分页对象
        # pg = MyPageNumberPagination() #自定义分页
        pa = PagerSerializers()

        # 在数据库中获取分页的数据
        pager_roles = pg.paginate_queryset(queryset=roles, request=request, view=self)

        # 对数据进行序列化
        ser = PagerSerializers(instance=pager_roles, many=True)
        return Response(ser.data)

从第N条索引开始显示，显示N条

from rest_framework.response import Response
from rest_framework.pagination import LimitOffsetPagination

class MyLimitOffsetPagination(LimitOffsetPagination):
    default_limit = 2
    limit_query_param = 'limit' # 向后取多少条
    offset_query_param = 'offset' # 从n（offset=n ）索引开始取
    max_limit = 6

class Pager1View(APIView):
    def get(self, request, *args, **kwargs):
        # 获取所有数据
        roles = models.Role.objects.all()

        # 创建分页对象
        # pg = MyPageNumberPagination() #自定义分页
        pg = MyLimitOffsetPagination() 

        # 在数据库中获取分页的数据
        pager_roles = pg.paginate_queryset(queryset=roles, request=request, view=self)

        # 对数据进行序列化
        ser = PagerSerializers(instance=pager_roles, many=True)
        return Response(ser.data)

from api.utils.serializers.pager import PagerSerializers
from rest_framework.response import Response
from rest_framework.pagination import CursorPagination

class MyCursorPagination(CursorPagination):
    cursor_query_param = 'cursor'
    page_size = 2
    ordering = 'id'

class Pager1View(APIView):
    def get(self, request, *args, **kwargs):
        # 获取所有数据
        roles = models.Role.objects.all()

        # 创建分页对象
        # pg = MyPageNumberPagination() #自定义分页
        pg = MyCursorPagination()

        # 在数据库中获取分页的数据
        pager_roles = pg.paginate_queryset(queryset=roles, request=request, view=self)

        # 对数据进行序列化
        ser = PagerSerializers(instance=pager_roles, many=True)
        # return Response(ser.data)
        return pg.get_paginated_response(ser.data) # 显示上一页和下一页链接
