Firebase OTP验证onVerificationCompleted未调用 [英] Firebase OTP verification onVerificationCompleted not called

问题描述

我正在尝试设置OTP验证，因此，当用户输入他们的电话号码时，我会向他们发送一个个人识别码，并调用 onCodeSent()并收到该个人识别码，但是问题是调用 onVerificationCompleted()时，我想转到另一个活动，用户可以在其中输入代码图钉进行验证，但根本没有调用它，我也不明白为什么.任何帮助将不胜感激，谢谢.

I'm trying to set up OTP verification so when the user enters their phone number, I send them a pin code, the onCodeSent() is called and I receive the code pin, but the problem is when onVerificationCompleted() is called, I would like to move to another activity where the user can enter the code pin to verify but it is not called at all and I don't understand why. Any help would be appreciated guys, thank you.

val auth = PhoneAuthOptions
    .newBuilder(FirebaseAuth.getInstance())
    .setPhoneNumber(phoneNumber)
    .setTimeout(60L,TimeUnit.MILLISECONDS)
    .setActivity(this)
    .setCallbacks(object : PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
        override fun onVerificationCompleted(p0: PhoneAuthCredential) {
            // here i want to get the smscode and send it over the next activity to verify
            // but this method is not called at all 
                                
            Intent(this,ChangePasswordActivity::class.java).apply {
                putExtra("code",p0.smsCode)
                startActivity(this)
            }
        }

        override fun onVerificationFailed(p0: FirebaseException) {
            Timber.d("Firebase Exception ${p0.message}")
        }

        override fun onCodeSent(code: String, p1: PhoneAuthProvider.ForceResendingToken) {
            super.onCodeSent(code, p1)
        }

        override fun onCodeAutoRetrievalTimeOut(p0: String) {
            super.onCodeAutoRetrievalTimeOut(p0)
        }
    })
    .build()

PhoneAuthProvider.verifyPhoneNumber(auth)

推荐答案

onVerificationCompleted() 仅在电话号码经过验证且没有用户输入的情况下才被调用.要执行您尝试做的事情，您应该在 onCodeSent() 代替.

这是事件的大致流程(在

Here is a rough flow of events (that are covered in detail in the documentation):

1. 从用户那里获取电话号码
2. 致电 PhoneAuthProvider.verifyPhoneNumber(auth)(已经存在)以将图钉发送给用户
调用
3. onCodeSent()，并附带验证ID和重发令牌.
4. 在 onCodeSent()内，创建一个旨在启动"pin输入屏幕"的意图.带有验证ID.
5. 从用户那里获取图钉，然后通过调用 PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId，userInput)
将其与验证ID结合起来
6. 使用该凭据通过 signInWithCredential(credential)登录用户.

1. Obtain phone number from user
2. Call PhoneAuthProvider.verifyPhoneNumber(auth) (as you are already) to send the pin to the user
3. onCodeSent() is called, with the verification ID and a resending token.
4. Inside of onCodeSent(), create an intent to launch the "pin input screen" with the verification ID.
5. Get a pin from the user and then combine it with the verification ID by calling PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, userInput)
6. Use that credential to sign in the user using signInWithCredential(credential).

val auth = PhoneAuthOptions
    .newBuilder(FirebaseAuth.getInstance())
    .setPhoneNumber(phoneNumber)
    .setTimeout(60L,TimeUnit.MILLISECONDS)
    .setActivity(this)
    .setCallbacks(object : PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
        override fun onVerificationCompleted(credential: PhoneAuthCredential) {
            // if here, phone number was verified automatically
            mAuth.signInWithCredential(credential)
                 .addOnCompleteListener(/* ... */)
        }

        override fun onVerificationFailed(p0: FirebaseException) {
            Timber.d("Firebase Exception ${p0.message}")
        }

        override fun onCodeSent(verificationId: String, resendToken: PhoneAuthProvider.ForceResendingToken) {
            // if here, code was sent to phone number
            // open pin input screen
            Intent(this,ChangePasswordActivity::class.java).apply {
                putExtra("verificationId",verificationId)
                startActivity(this)
            }
        }

        // we aren't using onCodeAutoRetrievalTimeOut, so it's omitted.
    })
    .build()

PhoneAuthProvider.verifyPhoneNumber(auth)
