如何使用新的Firebase快速更新电子邮件和密码 [英] How to update both Email and Password with new Firebase in swift

问题描述

我正在使用Google的新Firebase开发应用程序. 而且我在更新用户电子邮件和密码时遇到问题.

I'm developing app with new firebase from google. And I'm having problem with updating user email and password.

这就是我尝试过的.

let currentUser = FIRAuth.auth()?.currentUser

currentUser?.updateEmail(email) { error in
    if let error = error {
        print(error)

    } else {
        // Email updated.
        currentUser?.updatePassword(password) { error in
            if let error = error {

            } else {
                // Password updated.
                print("success")

            }
        }
    }
}

但是在更新密码时会出现这样的错误.

But when updating password this occurs error like this.

"Domain = FIRAuthErrorDomain代码= 17014"此操作敏感，需要最近的身份验证..."

"Domain=FIRAuthErrorDomain Code=17014 "This operation is sensitive and requires recent authentication..."

据我了解，我们必须在更新电子邮件后重新配置用户.

As I know we have to re-configure user after updating email.

我尝试使用此代码从Firebase重新配置.

I tried with this code for re-cofiguring from the firebase.

let user = FIRAuth.auth()?.currentUser
var credential: FIRAuthCredential

// Prompt the user to re-provide their sign-in credentials

user?.reauthenticateWithCredential(credential) { error in
  if let error = error {
    // An error happened.
  } else {
    // User re-authenticated.
  }
}

但这会发生错误

在初始化之前使用的变量凭据"

Variable 'credential' used before being initialed

我知道这是因为我没有初始化'credential'变量，但是我不知道如何解决这个问题.

I know this is because I don't initialize 'credential' variable but I don't know how to fix this to work.

有人知道解决方法吗?

推荐答案

在您进行的编辑中，您没有初始化FIRAuthCredential ...它应该是var credential = FIRAuthCredential()或只是像下面的代码一样使用它

In your edit you didn't initialize your FIRAuthCredential ... it should be var credential = FIRAuthCredential() or simply use it like below code

let credential = FIREmailPasswordAuthProvider.credentialWithEmail(email, password: password)

user?.reauthenticateWithCredential(credential) { error in
   if let error = error {
       // An error happened.
   } else {
      // User re-authenticated.
   }
 }
