### receiver.php 开发升级步骤 #### 步骤 1: 0.6 订阅机制发生了变化, **$this->message** 结构可以参阅文段代码. || 示例 以下示例为用户模拟图片消息, PicTran 默认订阅图片消息. ``` defined('IN_IA') or exit('Access Denied'); class PicTranModuleReceiver extends WeModuleReceiver { public function receive() { $type = $this->message['type']; //这里定义此模块进行消息订阅时的, 消息到达以后的具体处理过程, 请查看微擎文档来编写你的代码 $c = ''; foreach ($this->message as $key => $value) { $c .= "$key : $value \r\n"; } file_put_contents('e:\\receive.txt', $c); } } ``` || 执行结果 当操作员对某公众号进行后台管理操作时, 将会执行消息订阅, 文件输出结果为: ``` from : fromUser to : toUser time : 1413941559 type : image event : tousername : toUser fromusername : fromUser createtime : 1413941559 msgtype : image picurl : http://www.baidu.com/img/bdlogo.gif msgid : 1234567890123456 url : http://www.baidu.com/img/bdlogo.gif ```
