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)
