android - 如何在 Firebase Phone Authentication Android 中重新发送短信验证？

Question

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

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;
    }
};

我的问题是关于onCodeSent 方法。它在此处的文档上说(https://firebase.google.com/docs/reference/android/com/google/firebase/auth/PhoneAuthProvider.ForceResendingToken)

token 可用于强制重新发送短信验证码。但是，在对文档进行了一些研究之后，我仍然不知道该怎么做。

请问如何使用token重发短信验证？

这是用于重新发送 SMS 验证的方法。

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
}
