如何在通知单击时打开带有效数据的应用程序特定页面

Question

我正在开发一个cordova应用程序，其中我使用phonegap推送插件发送gcm通知。我正在尝试打开应用程序的特定页面，其中包含通知点击时收到通知的有效负载数据。

我的有效负载数据的服务器端代码

$messageData = array('message' => $Msg, 'title' => $Sub, 'notId' => $gcm_notid, 'timestamp' => $n_createdOn, 'sender' => $Sender, 'receiver' => $Receiver);

推送插件代码是：
