messaging.setBackgroundMessageHandler() not work

[chipchipzero]

This is my serviceworker code:

importScripts('https://www.gstatic.com/firebasejs/3.9.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/3.9.0/firebase-messaging.js');
// Initialize the Firebase app in the service worker by passing in the
// messagingSenderId.
firebase.initializeApp({
  'messagingSenderId': "FIREBASE_MESSAGING_SENDER_ID"
});
// Retrieve an instance of Firebase Messaging so that it can handle background
// messages.
const messaging = firebase.messaging();
// [END initialize_firebase_in_sw]

// If you would like to customize notifications that are received in the
// background (Web app is closed or not in browser focus) then you should
// implement this optional method.
// [START background_handler]
messaging.setBackgroundMessageHandler(function(payload) {
  console.log('[firebase-messaging-sw.js] Received background message ', payload);
  // test custom notice
  const notificationTitle = 'Background Message Title';
  const notificationOptions = {
    body: 'Background Message body.',
    icon: '/images/favicon.png'
  };

  return self.registration.showNotification(notificationTitle,
      notificationOptions);
});

I'm using fcm ruby gem to send message: https://github.com/spacialdb/fcm

This is my code:

fcm = FCM.new("FIREBASE_CLOUD_MESSAGING_KEY")

payload = {
  data: {
    object: data[:object],
    type: data[:type],
    notification: {title: data[:title], body: data[:message]}
  }
}
fcm.send(DEVICE_TOKEN, payload)

This is the result:

@thanhlongmuah do you see anything in your console - specifically the message "[firebase-messaging-sw.js] Received background message "

Can you try the following payload code:

fcm = FCM.new("FIREBASE_CLOUD_MESSAGING_KEY")

payload = {
  data: {
    object: data[:object],
    type: data[:type],
  }
}
fcm.send(DEVICE_TOKEN, payload)

Just to see if that changes the output.

@gauntface thanks for your response.
I didn't see any thing in console. I have been tried your code already but it doesn't work.

See #71.

@thanhlongmuah Sorry, I'm going to need more information to help solve this.

Can you provide example CURL requests you are sending?

@gauntface I found the reason: fcm ruby gem add notification automatically
