Question

我的申请存在问题：我成功配置了我的应用程序以使用FCM，当我尝试使用Firebase / Notification GUI发送消息时，它运行良好。我通过使用令牌或应用程序收到通知。

但我的问题是我想使用Google提供的REST api来使用我的服务器发布通知。这是我发送的POST数据：

URL: https://fcm.googleapis.com/fcm/send
Method POST
Authorization: key=... (I have the autorisation to post the message)
Content-Type : application/json
Payload :
{
 "to":"{MyToken}",
  "data":{
        "message":"Bonjour comment ça va",
    }
}

我收到了通知已发送的回复，但我的手机上没有收到任何内容。

{
"multicast_id": 
4752603394640553000
,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
  {
"message_id": "0:1501772371010731%1496332af9fd7ecd"
}
],
}

最后这是我的Android代码：

创建MainActivity：

FirebaseMessaging.getInstance().subscribeToTopic("jenkins");
String token = FirebaseInstanceId.getInstance().getToken();
String msg = getString(R.string.msg_token_fmt, token);
Log.i("token",token);
Toast.makeText(MainActivity.this,msg,Toast.LENGTH_SHORT).show();

MyFireBaseInstanceID：

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

/**
 * Created by Alexandre Michaud on 02/08/2017.
 */

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private static final String TAG = "MyFirebaseIIDService";

    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // If you want to send messages to this application instance or
        // manage this apps subscriptions on the server side, send the
        // Instance ID token to your app server.
        sendRegistrationToServer(refreshedToken);
    }

    private void sendRegistrationToServer(String token) {
        // TODO: Implement this method to send token to your app server.
    }


}

MyFirebaseMessagingService：

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

/**
 * Created by Alexandre Michaud on 02/08/2017.
 */

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // [START_EXCLUDE]
        // There are two types of messages data messages and notification messages. Data messages are handled
        // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
        // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
        // is in the foreground. When the app is in the background an automatically generated notification is displayed.
        // When the user taps on the notification they are returned to the app. Messages containing both notification
        // and data payloads are treated as notification messages. The Firebase console always sends notification
        // messages. For more see: 
        // [END_EXCLUDE]

        // TODO(developer): Handle FCM messages here.
        // Not getting messages here? See why this may be: 
        Log.d(TAG, "From: " + remoteMessage.getFrom());

        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0) {
            Log.d(TAG, "Message data payload: " + remoteMessage.getData());
            handleNow();


        }

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
            Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
        }

        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated. See sendNotification method below.
    }
    // [END receive_message]

    /**
     * Handle time allotted to BroadcastReceivers.
     */
    private void handleNow() {
        Log.d(TAG, "Short lived task is done.");
    }

    /**
     * Create and show a simple notification containing the received FCM message.
     *
     * @param messageBody FCM message body received.
     */
    private void sendNotification(String messageBody) {
        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)
                .setContentTitle("FCM Message")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

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

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

最后清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.alexandremichaud.myapplication">

    <application

            </intent-filter>
        </service>

    </application>

</manifest>

所以，如果有人能帮助我，我会非常高兴！：）

The documentation解释说有两种类型的消息：通知和数据。您正在发送数据消息。这将导致调用onMessageReceived()并调用handleNow()。您应该看到日志消息短期任务已完成。没有通知。

根据您想要的行为，您可以发送通知消息：

  {
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification" : {
      "body" : "Bonjour comment ça va",
      "title" : "Your Title"
    }
  }

或包含通知和数据的消息。

另请参阅FCM Guide for handling messages。

使用REST未收到FCM通知
