firebase.auth().currentUser.getIdToken() 抛出“auth/user-token-expired”怎么办？

Question

First, I didn't think this was possible. The documentation states:

"Returns the current token if it has not expired. Otherwise, this will refresh the token and return a new one."

So in what case would it throw this error? If the refresh token expired, than why wouldn't it instead refresh it? What is the best way to recover from this? Set a timer and try again? Seems like an anti-pattern.

This doesn't happen often. I've seen it on safari iPhone, especially when waking up a tab that was signed in anonymously.

This happens when the user session is revoked or disabled. Revocation happens during big account changes, eg. when the user updates their email or password in another session or the user sessions are revoked via the Admin SDK .

The error will be thrown and the user is signed out and deactivated. The expectation is to sign in again or re-authenticate the user.
