创建FCM主题需要很长时间才能在控制台中显示 [英] Creating FCM Topics takes a long time to show in console

问题描述

当我订阅一个不存在的主题时.为什么在Firebase控制台中出现需要花一整天的时间?将直接创建还是在1天之后创建? (即使控制台中未显示它，我也可以访问它吗?)

When I subscribe to a topic which doesn't exist.. why would it take a day long to apear in the Firebase Console ? would be created directly or after 1 day ? (Can I access it even when it's not shown in the console ? )

我有一个使用推送通知的应用程序，因此我将为每个用户创建一个主题，以防他删除了一个以上的设备或令牌.有什么好办法可以实现这一目标，而不是主题?

I have an application that uses push notifications so I will create a topic for every user in case he has more that one device or token was deleted. is there a good way to achieve this rather than topics ?

推荐答案

当设备订阅该主题或服务器应用向其发送数据时，将立即创建该主题.但是确实需要几个小时，令牌才能显示在Firebase Notifications控制台的下拉列表中.

The topic is immediately created when a device subscribes to it, or a server app send data to it. But it indeed takes a few hours before tokens show up in the dropdown in the Firebase Notifications console.
