GCM client 試出來了,問題是server 如何傳送中文資料 (by c#)?

GCM client如果有按照google API console 開設好server key 及GCM enable

還有在 在 Cloud Console中 點「Get Started With Sample Application」 對

「mobile backedn app」開啟及設定, 並依需要改寫gcm_client (參考git 連結 2013/06/05版,2012版比較繁瑣還要自己架server)

應該都是可以連入 (取得client device Id就應該不是問題了 )

但,是如果從C#要推播訊息怎麼做?
其本上一堆範例是直接向 「http://android.googleapis.com/gcm/send」做請求,丟一堆參數就可以了
問題是卡在中文訊息的問題,這時雙方需要encode & decode一下了
先就c# console sample為例

            tRequest.ContentLength = byteArray.Length;

            Stream dataStream = tRequest.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);

            String sResponseFromServer = tReader.ReadToEnd();


            tReader.Close();
            dataStream.Close();
            tResponse.Close();
            return sResponseFromServer;
        }
    }
}

===========================以上是推播的動作===================

以下是手機收到訊息時如何解碼

====================in GcmBroadcastReceiver================

 public void onReceive(Context context, Intent intent){

       ...

       ...

       ....

       msg = new String( intent.getExtras().getString("message").getBytes(), "UTF-8");

     //這才是之前data.message的內容......

    

}

======================================================

以上,大家加油了
