Google's service include GCM can not access in my country.Can Service Worker push notification without gcm in chrome? Or if some hack technique can implement this?
回答1:
Chrome now also uses Firebase Cloud Messaging as its Push Service, which may be available in your country. You could also use a third party Push Notification platform. These would still need to access GCM or FCM but they might have some ways to get access in restricted areas. Just do a search for "push notification third party" to get a list of them.
Also see this answer and this one for more information. Be aware they are outdated, but the concepts are the same.
