原文：本文件用到的：jquery、tp框架+TP_3.2.2/Application/Home/Controller/StuController.class.php php Created by PhpStorm. User: root Date: 2018/4/17 Time: 16:32 /namespace Home\Controller; use Think\Controller; class StuController{

简化后：使用工具：jQuery、ThinkPHP框架+StuController.class.php (位于路径：/Application/Home/Controller/)，开发环境：PhpStorm。

本文用到：jquery、tp框架

TP_3.2.2/Application/Home/Controller/StuController.class.php
