如何在Firebase电话认证Android中重新发送短信验证？ [英] How to resend SMS verification in Firebase Phone Authentication Android?

问题描述

根据Firebase文档（ https://firebase.google.com/docs/auth/android/phone-auth#send-a-verification-code-to-the-users-phone ），有 callback 来处理电话号码身份验证。

  mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks （）{
 
 @Override 
 public void onVerificationCompleted（PhoneAuthCredential credential）{
 
 Log.d（TAG，onVerificationCompleted：+ credential）; 
 signInWithPhoneAuthCredential（凭证）; 
 
 $ b $ @覆盖
 public void onVerificationFailed（FirebaseException e）{
 
 Log.w（TAG，onVerificationFailed，e）; 
 
 $ b @Override 
 public void onCodeSent（String verificationId，
 PhoneAuthProvider.ForceResendingToken token）{
 
 Log.d（TAG， onCodeSent：+ verificationId）; 
 
 //保存验证ID并重新发送令牌，以便日后使用
 mVerificationId = verificationId; 
 mResendToken = token; 
} 
}; 
  

我的问题在 onCodeSent 方法上。它在这里对文档说（ https：/ /firebase.google.com/docs/reference/android/com/google/firebase/auth/PhoneAuthProvider.ForceResendingToken ）

即令牌可用于强制重新发送短信验证码。但是，在对文档进行一些研究之后，我仍然不知道如何。

我想问一下如何使用这个标记

解决方案

这是用来重发短讯验证的方法。

 私人void resendVerificationCode（String phoneNumber，
 PhoneAuthProvider.ForceResendingToken token）{
 PhoneAuthProvider.getInstance（）。verifyPhoneNumber（
 phoneNumber，//电话号码验证
 60，//超时时间
 TimeUnit.SECONDS，//超时单位
 this，// Activity（用于回调绑定）
 mCallb ack，// OnVerificationStateChangedCallbacks 
 token）; //从回调中得到ForceResendingToken 
 
 $ $ $ $ $ $ $ $ $ $
According to Firebase documentation (https://firebase.google.com/docs/auth/android/phone-auth#send-a-verification-code-to-the-users-phone), there is callback for handling the phone number authentication.
mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {

    @Override
    public void onVerificationCompleted(PhoneAuthCredential credential) {

        Log.d(TAG, "onVerificationCompleted:" + credential);
        signInWithPhoneAuthCredential(credential);
    }

    @Override
    public void onVerificationFailed(FirebaseException e) {

        Log.w(TAG, "onVerificationFailed", e);
    }

    @Override
    public void onCodeSent(String verificationId,
                           PhoneAuthProvider.ForceResendingToken token) {

        Log.d(TAG, "onCodeSent:" + verificationId);

        // Save verification ID and resending token so we can use them later
        mVerificationId = verificationId;
        mResendToken = token;
    }
};
My question is on onCodeSent method. It said on the doc here (https://firebase.google.com/docs/reference/android/com/google/firebase/auth/PhoneAuthProvider.ForceResendingToken) 

that the token can be used to force re-sending an SMS verification code. However, after doing some research on the doc I still don't know how.

I would like to ask how to use this token to resend the SMS verification ?

This is the method used to resend SMS Verifications.
private void resendVerificationCode(String phoneNumber,
                                    PhoneAuthProvider.ForceResendingToken token) {
    PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phoneNumber,        // Phone number to verify
            60,                 // Timeout duration
            TimeUnit.SECONDS,   // Unit of timeout
            this,               // Activity (for callback binding)
            mCallbacks,         // OnVerificationStateChangedCallbacks
            token);             // ForceResendingToken from callbacks
}
