FCM推送通知在本地有效，但在服务器上无效

Question

I have been struggling to make push notifications work. I am recieving the following error

; FirebaseError: Messaging: We are unable to register the default service worker. Failed to register a ServiceWorker: A bad HTTP response code (404) was received when fetching the script. (messaging/failed-serviceworker-registration).

I have already tried to google and applied https://stackoverflow.com/a/42264578/5192105

But still it works locally but not on the server . The js file firebase-messaging-sw.js exists in the path: https://mobile-app.golocall.com/api/src/public/firebase-messaging-sw.js

I have used slim-php as backend framework.

Please help me out in resolving the error.

Answer 1

It tries to find the service worker file on the root of the application; hence the application tries to load

https://mobile-app.golocall.com/firebase-messaging-sw.js

while the actual file is located at

https://mobile-app.golocall.com/api/src/public/firebase-messaging-sw.js

EDIT:
You may be able to import the service worker like this:

importScripts('https://www.gstatic.com/firebasejs/4.8.1/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/4.8.1/firebase-messaging.js');

If this doesn't work, you may need to declare your own service worker.
