如何在Django Rest框架中进行条件渲染？

Question

例如，如果“localhost:8000/member/memberlist？wantjson=True”以json格式返回，或

如果“localhost:8000/member/memberlist？wantexel=True”，我想编写一段返回exel的代码。我在这里怎么做

这是我的密码

class MemberViewSet(XLSXFileMixin, ReadOnlyModelViewSet):
def get_renderers(self):
    self.renderer_classes = [XLSXRenderer, JSONRenderer]
    for renderer in self.renderer_classes:
        print(renderer)

    return [renderer() for renderer in self.renderer_classes]

@action(detail=False, methods=["get"], url_path="memberlist")
def memberlist(self, request):
   result_json= request.data('wantjson')
   result_exel= request.data('wantexel')
   if result_json : 
       self.renderer_classes= JSONRenderer
       
   elif result_exel:
       self.renderer_classes= XLSXRenderer
   resultList = Member.objects.all()    
   serializer = MemberSerializer(resultList, many=True)
   return Response(serializer.data)
