我最近实现了谷歌登录。它工作正常,但有一件事困扰着我。
当用户第一次登录时,会打开一个窗口供用户登录 google 并选择他的帐户。但是,当用户注销并再次尝试通过 google 登录时,会以某种方式记住他之前的登录,而他刚刚登录。
每次用户选择通过 google 登录时,如何实现要求 google 登录?
这就是我注销用户的方式:
try! Auth.auth().signOut()
登录:
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error?) {
if let error = error {
print("Failed logging into Google: ", error)
return
}
print("Successfully logged into Google.")
guard let authentication = user.authentication else { return }
let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken,
accessToken: authentication.accessToken)
Auth.auth().signIn(with: credential) { (acc, error) in
if let error = error {
print("Failed to create User with Google: ", error)
return
}
let databaseRef = Database.database().reference()
guard let uid = Auth.auth().currentUser?.uid else { return }
databaseRef.child("users").observeSingleEvent(of: .value, with: { (snapshot) in
if snapshot.hasChild("\(uid)") {
print("Data found.")
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "ProfileViewController") as! ProfileViewController
vc.readLeasing()
vc.readData()
} else {
self.upDataToDatabase(from: user)
}
})
let defaults = UserDefaults.standard
logInViaGoogle = true
defaults.set(logInViaGoogle, forKey: "logInViaGoogle")
print("Successfully created user with Google.")
}
}
最佳答案
如 Firebase google auth automatically selecting user. How to force it to select account 中所述
你可以这样做
var provider = new firebase.auth.GoogleAuthProvider();
provider.setCustomParameters({
prompt: 'select_account'
});
