浏览器中输入http://localhost:8080/thimk/index.php/Home/Main/XianShi/name/li/age/22即可运行显示

如要运行CeShi(),还要在View中建文件夹Main，在该新建文件夹中建CeShi.html文档

CeShi.html：

<head>
<meta charset="utf-8" />
<title>无标题文档</title>
</head>

<body>
<a href="/thimk/index.php/Home/Main/XianShi/name/li/age/22">调用显示操作</a>

<div><{$text}></div>
<form action="__CONTROLLER__/XianShi" method="post">
<input type="text" name="name" />
<input type="submit" value="提交" />
</form>

</body>

浏览器中输入http://localhost:8080/thimk/index.php/Home/Main/CeShi即可运行显示
