firebase-cloud-messaging

问题 I am testing out the Firebase Cloud Messaging function in my React app which was bootstrapped with create-react-app. Note that I have already intialized firebase (including admin SDK on server-side) properly and my client side is deployed on https. What I did so far was to: Initialize firebase messaging in firebase.js, and also request for notification permission and listen out for onMessage event const messaging = firebase.messaging(); messaging .requestPermission() .then(() => { console.log

问题 I am working via Postman to send a FCM push notification to my phone that already has the app installed. I have push notifications enabled, the app is on the background, and I have a valid (confirmed) Firebase push token. I'm POSTing to https://fcm.googleapis.com/fcm/send with the headers (Authorization: key=APP_SERVER_KEY, Content-Type: application/json), and my body looks like: { "notification": { "title": "Portugal vs. Denmark", "text": "5 to 1" }, "to": MY_PUSH_TOKEN } I'm getting the

问题 I'm trying to send notifications to a specific device with Firebase but am getting the following error: {"r": {"results":[{"error":{"code":"messaging/mismatched-credential","message":"The credential used to authenticate this SDK does not have permission to send messages to the device corresponding to the provided registration token. Make sure the credential and registration token both belong to the same Firebase project."}}],"canonicalRegistrationTokenCount":0,"failureCount":1,"successCount"

问题 I'm developing an android app using firebase, this app should push notifications twice a day by hours user should set in app settings. I saw a similar question was asked at least 2 years ago, but no answer, maybe now there is an option to do it. Is there anyway I can achieve this using Firebase ? If no, how can I achieve it ? 回答1: You can schedule sending notifications from the Firebase console. But that is limited to notifications you manually enter. There is no way to schedule "twice a day"

Within my firebase class i try to get the data: @Override public void onMessageReceived(RemoteMessage remoteMessage) { super.onMessageReceived(remoteMessage); Intent intent = new Intent(this, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY

问题 I think I have completed every step necessary to convert my messaging app from GCM to FCM but it is not working. FCM is currently returing MismatchSenderId.

问题 I've been implementing Notification Channels in my android app to support recent android versions. You can set the notification channel id when sending messages from the firebase web console, but I was not able to find out how to set the channel id when sending messages via fcm rest api. Notification channels are not mentioned in the reference (https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages), but I am pretty sure there must be a way to set the channel id. 回答1: The
