微信`sdk`

微信

wechat-php-sdk

下载zip包，只需要wechat.class.php和demo.php

将wechat.class.php复制到ThinkPHP/Library/Org/Util/下，然后在控制器中如下引入

import('Org.Util.wechat');//进入

$weObj = new \Wechat($option);//实例化，$option是微信的配置，在demo.php中有demo

官方demo

include "wechat.class.php";
$options = array(
 'token'=>'tokenaccesskey', //填写你设定的key
 'encodingaeskey'=>'encodingaeskey' //填写加密用的EncodingAESKey，如接口为明文模式可忽略
 );
$weObj = new Wechat($options);
$weObj->valid();//明文或兼容模式可以在接口验证通过后注释此句，但加密模式一定不能注释，否则会验证失败
$type = $weObj->getRev()->getRevType();
switch($type) {
 case Wechat::MSGTYPE_TEXT:
 $weObj->text("hello, I'm wechat")->reply();
 exit;
 break;
 case Wechat::MSGTYPE_EVENT:
 break;
 case Wechat::MSGTYPE_IMAGE:
 break;
 default:
 $weObj->text("help info")->reply();

自己改进后demo
