推荐答案

FCM Token 是 Instance ID 令牌，它代表已安装的应用程序，而不是已登录的用户.通常，一旦应用保持安装状态，无论哪个用户登录，它都会拥有相同的令牌.

The FCM Token is an Instance ID token, it represents the installed app and not the signed in user. Generally once the app remains installed it will have the same token no matter what user is signed in.

您必须自己管理与令牌关联的用户.当用户登录时，您应该将令牌与用户的 ID 相关联，当用户退出时，您应该删除该关联.

You would have to manage what user is associated to the token yourself. When the user signs in you should associate the token with the user's ID and when the user signs out you should remove that association.
