我没有收到任何通知。我正在使用firebase功能。功能正常。我在firebase日志中收到成功消息。
我的index.js功能：
let functions = require('firebase-functions');
let admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotification = functions.database.ref('/notifications/messages/{pushId}')
.onWrite(event => {
if (!event.data.current.val()) {
return console.log('User ');
}
const message = event.data.current.val();
const senderUid = message.from;
const receiverUid = message.to;
const promises = [];
if (senderUid == receiverUid) {
//if sender is receiver, don't send notification
promises.push(event.data.current.ref.remove());
return Promise.all(promises);
}
const getInstanceIdPromise = admin.database().ref(`/users/${receiverUid}/instanceId`).once('value');
const getSenderUidPromise = admin.auth().getUser(senderUid);
return Promise.all([getInstanceIdPromise, getSenderUidPromise]).then(results => {
const instanceId = results[0].val();
const sender = results[1];
console.log('notifying ' + receiverUid + ' about ' + message.body + ' from ' + senderUid);
const notification = {
data: {
title: sender.displayName,
body: message.body,
//icon: sender.photoURL
}
};
return admin.messaging().sendToDevice(instanceId, payload)
.then(function (response) {
console.log("Successfully sent message:", payload);
console.log("Successfully sent message:", response);
})
.catch(function (error) {
console.log("Error sending message:", error);
});
});
});
我正在获取令牌，数据库也是正确的。 MyFirebaseMessaging类
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
String title = remoteMessage.getData().get("title");
String message = remoteMessage.getData().get("text");
String username = remoteMessage.getData().get("username");
String uid = remoteMessage.getData().get("uid");
String fcmToken = remoteMessage.getData().get("fcm_token");
// Don't show notification if chat activity is open.
if (!ChatMainApp.isChatActivityOpen()) {
sendNotification(title,
message,
username,
uid,
fcmToken);
} else {
EventBus.getDefault().post(new PushNotificationEvent(title,
message,
username,
uid,
fcmToken));
}
}
}
/**
* Create and show a simple notification containing the received FCM message.
*/
private void sendNotification(String title,
String message,
String receiver,
String receiverUid,
String firebaseToken) {
Intent intent = new Intent(this, chat.class);
intent.putExtra("receiver", receiver);
intent.putExtra("receiverid", receiverUid);
intent.putExtra("firebasetoken", firebaseToken);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_notifications_black_24dp)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}

我已在应用程序标记内的清单中指定了服务，并且我获取了令牌，并且我已将其存储在users表中。
永远不会调用OnMessageReceived，我尝试调试它。
请有人帮我这个。

也许您错过了FirebaseInstanceIdService的设置。
<强>的Manifest.xml
<service android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is called when the InstanceID token
* is initially generated so this is where you would retrieve the token.
*/
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
}}
您需要此服务进行注册，以便fcm可以找到您的设备。
