Java GCM推送通知

我能够成功地从GCM发送推送通知，但无法捕获来自意图数据的消息。 消息变量未获取任何数据

我的GCMinentService课程

protected void onMessage(Context context, Intent data) {
    String message;
    message = data.getExtras().getString("message");
    Log.i("message",data.toString());
    Intent intent = new Intent(this, GCMMessageView.class);
    intent.putExtra("message", message);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    Notification notification = new Notification.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setWhen(System.currentTimeMillis())
            .setContentTitle("Android GCM Tutorial")
            .setContentText(message).setContentIntent(pIntent)
            .build();
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(R.string.app_name, notification);

}

我的有效载荷

{
"message": "Hi I am nutritown",
"registration_ids":["registrationId"]
}

GCM的回应 {“多播_-id”：8633384191969300942，“成功”：1，“失败”：0，“规范_-id”：0，“结果”：[{“消息_-id”：“0:1420884152153321%b49c80e8f9fd7ecd”}]}

问题已经解决，我的请求有误

对GCM服务器的正确请求应为

{ 
"data": {
"message": "Hi I am message",
"key2": "value2"
},
"registration_ids":["registrationid"]
}
