还是应该从服务器端完成主题订阅?

Or subscribe to a topic should be done from server side?

推荐答案

Firebase Cloud Messaging的客户端Web SDK不支持订阅主题.如果要为Web客户端订阅FCM主题，则必须通过

The client-side web SDK for Firebase Cloud Messaging does not support subscribing to topics. If you want to subscribe your web clients to FCM topics, you will have to do so from server-side code, either through the Admin SDK or through the corresponding REST APIs.
