要从身份验证选项卡中删除用户，我使用以下代码：
if let user = FIRAuth.auth()?.currentUser{
user.delete(completion: nil)
}
当用户使用电子邮件/密码组合注册时，这工作得很好，但当他们使用社交帐户注册时，它们不会被删除，我仍然可以在“身份验证”选项卡中看到他们的电子邮件、UID 等。
如何从 Firebase 中删除这些用户？
提前致谢
谢谢 Jogendra，重新身份验证是解决我的问题的关键，我接受了答案。这是使用 Swift 3 的完整答案，其中包含用于检索用户凭据的代码。
func deleteAllUserData(){
if let user = FIRAuth.auth()?.currentUser{
user.delete(completion: { (err) in
if(err != nil){
print(err!.localizedDescription)
//Try to re-authenticate if there is an error
self.getProvider()
}else{
self.deleteData()
}
})
}
}
//There are different methods to retrieve the credentials based on the auth type so you first need to know which type of authentication is being used
func getProvider(){
if let providerData = FIRAuth.auth()?.currentUser?.providerData {
for userInfo in providerData {
switch userInfo.providerID {
case "facebook.com":
if let credential = facebookCredential(){
self.reauthenticate(credential: credential)
}
case "google.com":
if let credential = googleCredential(){
self.reauthenticate(credential: credential)
}
print("user is signed in with google")
case "password":
let alert = UIAlertController(title: "Sign In", message: "Please Sign In again to your Locket account to confirm that you want to delete all your data", preferredStyle: .alert)
alert.addTextField { (textField: UITextField) in
textField.placeholder = "Email"
}
alert.addTextField { (textField: UITextField) in
textField.placeholder = "Password"
textField.isSecureTextEntry = true
}
let noAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
let yesAction = UIAlertAction(title: "OK", style: .destructive, handler: { (action:UIAlertAction) in
let emailTextField = alert.textFields![0]
let passwordTextField = alert.textFields![1]
if let credential = self.emailCredential(email: emailTextField.text!, password: passwordTextField.text!){
self.reauthenticate(credential: credential)
}else{
print("error")
}
})
alert.addAction(yesAction)
alert.addAction(noAction)
self.present(alert, animated: true, completion: nil)
default:
print("unknown auth provider")
}
}
}
}
func reauthenticate(credential:FIRAuthCredential){
FIRAuth.auth()?.currentUser?.reauthenticate(with: credential) { error in
if let error = error {
print("reauth error \(error.localizedDescription)")
} else {
print("no reauth error")
self.deleteData()
}
}
}
func facebookCredential() -> FIRAuthCredential? {
let credential = FIRFacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)
return credential
}
func emailCredential(email:String,password:String) -> FIRAuthCredential? {
let credential = FIREmailPasswordAuthProvider.credential(withEmail: email, password: password)
return credential
}
func googleCredential() -> FIRAuthCredential? {
guard let user = GIDSignIn.sharedInstance().currentUser else {return nil}
guard let authentication = user.authentication else {return nil}
let credential = FIRGoogleAuthProvider.credential(withIDToken: authentication.idToken, accessToken: authentication.accessToken)
return credential
}
func deleteData(){
// Delete all other data related to user
}
