一首先手动创建php文件，然后在微信公众平台服务器配置指定执行这个文件，那么每次微信公众号发消息就会执行这个文件，我们
可以在这个文件中指定菜单点击事件和消息内容处理、设置自动回复规则等。具体见下面php:
<?php
/*** wechat php test

define("TOKEN", "oliveche_test");

require_once(dirname(__FILE__) . "/WxPayPubHelper/WxPay.pub.config.php");

if (!isset($_GET['echostr'])) {
$wechatObj->responseMsg();
$flage = false;
}else{
$wechatObj->valid();
}

exit;
