firebase-authentication

问题 I'm using the Spark Framework hosted on Heroku and I have this in my main : method in my server post("/token", (request, response) -> "Hello World"); That's working fine, however, I want to actually send a custom token, and not just "Hello World".

For this purpose I have this check: func isNewUser(userMetadata: UserMetadata) -> Bool { return userMetadata.creationDate == userMetadata.lastSignInDate && !UserDefaults.standard.hasLoggedIn } I need the UserDefaults check because creationDate and lastSignInDate will be equal till the moment the user logs out. Everything

问题 I was previously able to trigger onAuthStateChanged without needing to sign user out after they verified their email using these methods called one after another. firebase.auth.currentUser.reload() firebase.auth.currentUser.getToken(true) I updated them to getIdToken firebase.auth.currentUser.reload() firebase.auth.currentUser.getIdToken(true) However with v4 of firebase previous and new approach are not re-triggering onAuthStateChange anymore.
