我在firebase身份验证中更改电子邮件地址时遇到一些问题。 我的代码现在看起来像这样:

func changeEmail(withEmail email: String, completion: @escaping ((Bool) -> Void)) {
    guard let currentUser = Auth.auth().currentUser, let email = mail else { return }
    currentUser.updateEmail(to: email) { [weak self]
        error in
        guard let self = self else { return }
        let title: String
        let message: String
        if let error = error {
            title = "alert.error.title".localized()
            message = error.localizedDescription
        } else {
            title = email
            message = "auth.confirm.email.popup".localized()
            currentUser.sendEmailVerification()
        }
        self.navigator.showAlert(title: title,
                                 message: message,
                                 bottomLeftTitle: "general.got.it".localized(),
                                 bottomLeftHandler: { completion(error == nil)
        })
    }
}
所以它很好用,用户可以更改电子邮件

但当用户停留时间过长,需要重新登录时,问题就会出现。每个人都知道这会干扰应用程序中的用户体验

Auth.auth().reload() //not working in this situation.

那么,如何在不要求用户注销并再次登录的情况下更改电子邮件呢?

有一种
重新验证
的方法正好用于此目的。

您需要做的是再次询问用户的登录凭据。无需注销-需要登录

可能的代码:

if (self.newPassword == self.newPasswordConfirm) && (!(self.newPassword.isEmpty) || !(self.newUserName.isEmpty)) {
    reauthenticate(email: self.accountEmail, password: self.oldPassword) { isSucceeded in
        //Successfully authenticated
        if isSucceeded == true {
            if !self.newUserName.isEmpty {
                // update username
            }
            
            Auth.auth().currentUser?.updatePassword(to: self.newPassword) { (error) in
                // Alert user that it didn't work
            }
            
            self.editProfile.toggle()
        }
        // Failed to reauthenticate
        else if isSucceeded == false {
            // Alert User
        }
    }
}
