Question

大家好，我一直在实现gcm，但问题是它没有收到通知，我已经尝试过从我的项目Web服务器发送gcm消息并尝试在android上实现它但仍然没有用，它正在生成令牌ID但它没有收到任何消息，以下是我用于实现gcm

的类

GcmServiceListner.class

public class GcmServiceListner extends GcmListenerService {
private static final String TAG = "MyGcmListenerService";
private PreferencesHandler ph;

@Override
public void onMessageSent(String msgId) {
    super.onMessageSent(msgId);
    Log.e("Anas", "MESSAGE SENT");
}

@Override
public void onMessageReceived(String from, Bundle data) {
    try {
        ph = new PreferencesHandler(this);
        int notiNum = ph.getChatNotificationNumberName();
        notiNum++;
        ph.setChatNotificationNumberName(notiNum);
        String message = data.getString("data");
        Log.d(TAG, "From: " + from);
        Log.d(TAG, "Message: " + message);

        if (from.startsWith("/topics/")) {
            // message received from some topic.
        } else {
            // normal downstream message.
        }

        // [START_EXCLUDE]
        /**
         * Production applications would usually process the message here.
         * Eg: - Syncing with server.
         *     - Store message in local database.
         *     - Update UI.
         */

        /**
         * In some cases it may be useful to show a notification indicating to the user
         * that a message was received.
         */
        sendNotification(message);
    } catch (Exception e) {
        e.printStackTrace();
    }


    // [END_EXCLUDE]
}
// [END receive_message]

/**
 * Create and show a simple notification containing the received GCM message.
 *
 * @param message GCM message received.
 */
private void sendNotification(String message) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_media_pause)
            .setContentTitle("GCM Message")
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
 }
}

正如您所看到的，我已经覆盖了 onMessageSend 的方法，当我实现从应用程序内部发送消息时，它会在几分钟后调用此方法时发送消息通过gcm但仍然onMessageReceived方法不起作用，以下是我从应用程序调用send函数时的代码

gcm = GoogleCloudMessaging.getInstance(this);
    new AsyncTask<Void, Void, String>() {
        @Override
        protected String doInBackground(Void... params) {
            String msg = "";
           Log.e(TAG,"upstream");
            try {
                Bundle data = new Bundle();
                data.putString("data", "Hello World");

                String id = SENDING_ID;
                gcm.send(to+"@gcm.googleapis.com", id, data);
                msg = "Sent message";
            } catch (IOException ex) {
                msg = "Error :" + ex.getMessage();
            }
            return msg;
        }

        @Override
        protected void onPostExecute(String msg) {
            Log.e(TAG, msg + "   msg");
        }
    }.execute();

“to”over是我必须发送邮件的令牌ID，“SENDING_ID”是从Google服务器生成的ID

现在以下是我的web服务器的php代码，我正在实现gcm发送代码

define( 'API_ACCESS_KEY', API_KEY );
    $fields = array(
        'to' => TOKEN_ID,
        'data' => "TEST MESSAGE",
    );

    $headers = array(
    'Authorization: key='.API_KEY,
        'Content-Type: application/json'                            
        );
        echo json_encode($fields);
        // Open connection
        $ch = curl_init();

        // Set the url, number of POST vars, POST data

        curl_setopt($ch, CURLOPT_URL,"https://gcm-http.googleapis.com/gcm/send");

        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );

        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

        curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false);
        // Execute post
        $result = curl_exec($ch);
        if ($result === FALSE) {
            echo "ERROR IN CURL";
        }else{
            echo "ERROR FREE CURL";
        }

请帮我解决我现在要做的事情： - ）

Answer 1

这是我的两个建议： 1.如果您使用物理手机测试打开的Chrome浏览器并将其发布在网址栏chrome：// inspect /＃devices（这将显示您的设备是否已连接到您的PC端口）。 / p>

2.在上游的客户端，您应该更改代码

 gcm.send(to+"@gcm.googleapis.com", id, data);

，因为： id是一个唯一的msg id，每次发送一个msg时都应该是唯一的（否则GCM可能会忽略它，并且它不会被发送到你的服务器）

最后你的服务器期待一个令牌，因此你应该有一个代码，当服务器收到一个消息时它会提取它（你的服务器现在没有提取任何它可以在上游或下游）

现在，如果你想进行基本的测试，你可以通过在TOKEN_ID中手动复制和粘贴客户端的令牌（你的手机）以及你的api密钥来对你进行硬编码。 / p>

GCM未收到通知
