问题描述
当我订阅一个不存在的主题时.. 为什么要花一天时间才能出现在 Firebase 控制台中?是直接创建还是 1 天后创建?(即使控制台中没有显示，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，以防他有多个设备或令牌被删除.有没有一种好方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
当设备订阅主题或服务器应用向其发送数据时，会立即创建主题.但确实需要几个小时，令牌才会出现在 Firebase 通知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.
