CreateModelMixin: 定义了创建一个序列对象的方法create(self, request, *args, **kwargs)，保存方法perform_create(self, * * * serializer)，成功获取请求头的方法：get_success_headers(self, data)
ListModelMixin：定义了一个获取查询集的方法, many=True：list(self, request, *args, **kwargs)
RetrieveModelMixin: 定义了一个检索方法，retrieve(self, request, *args, **kwargs)
UpdateModelMixin：更新一个模型实例，update(self, request, *args, **kwargs)
DestroyModelMixin：删除一个模型实例，方法destroy(self, request, *args, **kwargs)
