### receiver.php 開發升級步驟 #### 步驟 1: 0.6 訂閱機制發生了變化, **$this->message** 結構可以參閱文段代碼. || 示例 以下示例為用戶模擬圖片消息, PicTran 默認訂閱圖片消息. ``` defined('IN_IA') or exit('Access Denied'); class PicTranModuleReceiver extends WeModuleReceiver { public function receive() { $type = $this->message['type']; //這里定義此模塊進行消息訂閱時的, 消息到達以后的具體處理過程, 請查看微擎文檔來編寫你的代碼 $c = ''; foreach ($this->message as $key => $value) { $c .= "$key : $value \r\n"; } file_put_contents('e:\\receive.txt', $c); } } ``` || 執行結果 當操作員對某公眾號進行后臺管理操作時, 將會執行消息訂閱, 文件輸出結果為: ``` 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 ```
