我目前正在尝试将我的应用迁移到Firebase，并且正在寻找与Firebase相当的Parse Installations and Channels.

I'm currently trying to migrate my app to firebase and I'm looking for the Firebase equivalent of Parse Installations and Channels.

我发现我们应该使用主题，但是在我的应用程序中订阅"和取消订阅"主题很常见，但是(我发现)无法看到一个主题用户已订阅.有什么想法吗?

What I've found is that we are supposed to use topics however in my app "subscribing" and "unsubscribing" to topics is common yet there is no way (that I have found) to see what topics a user is subscribed to. Any ideas?

我已经阅读了Firebase文档，但是我是Firebase的新手，所以也许有更多经验的人会知道: firebase.google/docs/cloud-messaging/android/topic-messaging#managing_topic_subscriptions_from_the_server

I've looked through the Firebase documentation but I'm new to Firebase so maybe someone with more experience would know: firebase.google/docs/cloud-messaging/android/topic-messaging#managing_topic_subscriptions_from_the_server

在此先感谢您的帮助！

推荐答案

FCM主题订阅基于应用程序的实例ID，因此，当您订阅或取消订阅主题时，将使用IID.

FCM topic subscriptions are based on an application's Instance ID, so when you subscribe or unsubscribe to or from a topic the IID is used.

您可以使用实例ID API获取有关特定IID的信息，此信息包括IID当前订阅的主题.请参见参考

You can use the Instance ID API to get information about a particular IID, this information includes the topics that the IID is currently subscribed to. See the reference
