16         pg = MyPageNumberPagination()
17         #在数据库中获取分页数据
18         pager_roles = pg.paginate_queryset(queryset=roles, request=request,view=self)
19         #对分页数据进行序列化
20         ser = BookSerilizer(instance=pager_roles, many=True)
21         return pg.get_paginated_response(ser.data)  #返回上一页或者下一页
