今天学RESTful API的编写，发现不知道怎么发送HTTP PUT/PATCH/DELETE请求，还是要学习一个。

使用curl_opt函数来发送各式各样的http请求动作，不仅限于get和post。

在测试自己的restful api的时候，通过访问这个代理发送http put/patch/delete请求的php页面，完成测试。

<?php

/**

 * http.php

 * 用来向服务器的RESTful API发起各类HTTP请求的工具函数。

 *

 * 使用: http://mysite.com/http.php?action=xxx

 * xxx \in {get,post,put,patch,delete}
