 微信 公众号 平台 接口 开发 验证 token 入门 简单 解析 xml 一个类

<?PHP

if (isset($_GET['echostr'])) { 

    $tmpArr = array('XXXX', $_GET["timestamp"], $_GET["nonce"]);
    sort($tmpArr, SORT_STRING);
    $tmpStr = implode( $tmpArr );
    $tmpStr = sha1( $tmpStr );
    if( $tmpStr == $_GET["signature"] ){ echo $_GET["echostr"]; exit; } 
} 

 下面是完整的类：

<?php

/*用于验证token
if (isset($_GET['echostr'])) { 

    $tmpArr = array('password', $_GET["timestamp"], $_GET["nonce"]);
    sort($tmpArr, SORT_STRING);
    $tmpStr = implode( $tmpArr );
    $tmpStr = sha1( $tmpStr );
    if( $tmpStr == $_GET["signature"] ){ echo $_GET["echostr"]; exit; } 
}
