在 Swift 中向新的 Firebase 用戶發送電子郵件驗證電子郵件

Question

我將我的應用程序設置為使用電子郵件地址和密碼成功登錄或創建 Firebase 帳戶。 我現在要做的是檢查用戶是否已經驗證了他們的電子郵件，如果沒有，則向他們發送 Firebase 允許我們編寫的驗證電子郵件。

@IBAction func createAccountTapped(_ sender: Any) {

    if let email = emailTextfield.text, let password = passwordTextfield.text {

        Auth.auth().createUser(withEmail: email, password: password, completion: { user, error in

            if let firebaseError = error {

                print(firebaseError.localizedDescription)

                return

            }

            self.presentTabBar()

        })

    }

}

@IBAction func loginTapped(_ sender: Any) {

    if let email = emailTextfield.text, let password = passwordTextfield.text {

        Auth.auth().signIn(withEmail: email, password: password, completion: {(user, error) in

            if let firebaseError = error {

                print(firebaseError.localizedDescription)

                return

            }

            self.presentTabBar()

        })

    }

}

這是我的“創建帳戶”和“登錄”功能。

我的問題是我不知道如何實現這個功能，也不知道在哪里調用這些函數。

你能告訴我發送這封電子郵件的功能是什么，以及檢查電子郵件是否通過驗證的功能是什么？

您可以在創建帳戶后立即發送驗證郵件：

（不要忘記創建一個額外的按鈕/操作，以便用戶可以再次請求驗證郵件）

private var authUser : User? {
    return Auth.auth().currentUser
}

public func sendVerificationMail() {
    if self.authUser != nil && !self.authUser!.isEmailVerified {
        self.authUser!.sendEmailVerification(completion: { (error) in
            // Notify the user that the mail has sent or couldn't because of an error.
        })
    }
    else {
        // Either the user is not available, or the user is already verified.
    }
}

結合您的代碼：

@IBAction func createAccountTapped(_ sender: Any) {
    if let email = emailTextfield.text, let password = passwordTextfield.text {

        Auth.auth().createUser(withEmail: email, password: password, completion: { user, error in

            if let firebaseError = error {
                print(firebaseError.localizedDescription)
                return
            }

            sendVerificationMail()


            self.presentTabBar()
        })
    }
}

檢查用戶是否已驗證：

@IBAction func loginTapped(_ sender: Any) {


    if let email = emailTextfield.text, let password = passwordTextfield.text {

        Auth.auth().signIn(withEmail: email, password: password, completion: {(user, error) in
            if let firebaseError = error {
                print(firebaseError.localizedDescription)
                return
            }

            if user != nil && !user!.isEmailVerified {
            // User is available, but their email is not verified.
            // Let the user know by an alert, preferably with an option to re-send the verification mail.
            }
            self.presentTabBar()
        })
    }
}
