使用GCM時發生IOException

我試圖向Android設備發送推送通知，但在以下情況下出現錯誤。使用GCM時發生IOException

String msg = "push message"; 
String to1 = "123456"; 
String from1 = "098776655";

這工作得很好：

Message message = new Message.Builder() 
    .collapseKey("1") 
    .addData("message", msg) 
    .addData("to1", to1) 
    .addData("to2", to1) 
    .build();

但使用以下時收到錯誤：

Message message = new Message.Builder() 
    .collapseKey("1") 
    .addData("message", msg) 
    .addData("to", to1) 
    .addData("from", from1) 
    .build();

我甚至代替from1使用的其他變量爲好，但仍然得到錯誤：

java.io.IOException: Server returned HTTP response code: 400 for URL: https://android.googleapis.com/gcm/send

堆棧跟蹤：

爲什麼你甚至會嘗試發送兩個具有相同名稱但不同值的參數？ –

對不起，這只是一個輸入錯誤在這裏，我現在已經糾正... – Arsalan

根據_GCM_文檔，確切的失敗原因在響應中描述。 –

謝謝，每次身體我有固定它...

的問題是什麼，我只是改變

.addData("from", from1)

要

.addData("from1", from1)

和它的作品...

可能是from是GCM服務器端的關鍵字...

這可能是您沒有權限訪問該網址，或者您需要安裝新的證書，由服務器提供的證書，你需要跟服務器端的接觸！

正如我上面提到的那樣，它在第一種情況下工作，但不在第二種情況下工作...... – Arsalan

如果你看看你從服務器（響應體）得到的響應，它會告訴你，from確實是一個保留字（因爲它在Android中用於Intents，據我所知）。
