Flutter Firebase电话身份验证不工作

Question

电话身份验证失败,出现以下异常：

PlatformException(ERROR_SESSION_EXPIRED,sms代码已过期。请重新发送验证码重试。,null）

但如果我使用的电话号码不同于我的电话号码，它就会起作用。我从play store中添加了SHA-1和SHA-256指纹到firebase，并替换了google-services.json。

这是我的代码：

 void _verifyPhoneNumber() async {
    setState(() {
       isVerified=true; 
      });
    setState(() {
      _message = '';
    });
    final PhoneVerificationCompleted verificationCompleted =
        (AuthCredential phoneAuthCredential) {
      _auth.signInWithCredential(phoneAuthCredential);
      setState(() {
        _message = 'Received phone auth credential: $phoneAuthCredential';

      });
    };

    final PhoneVerificationFailed verificationFailed =
        (AuthException authException) {
        _message =
            'Phone number verification failed';

    };

    final PhoneCodeSent codeSent =
        (String verificationId, [int forceResendingToken]) async {
      _verificationId = verificationId;

    };

    final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
        (String verificationId) {
      _verificationId = verificationId;
    };

    await _auth.verifyPhoneNumber(
        phoneNumber: '+91'+_phoneNumberController.text,
        timeout: const Duration(seconds: 5),
        verificationCompleted: verificationCompleted,
        verificationFailed: verificationFailed,
        codeSent: codeSent,
        codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
  }

  // Example code of how to sign in with phone.
  void _signInWithPhoneNumber() async {
    setState(() {
      isLoading=true;
    });
    final AuthCredential credential = PhoneAuthProvider.getCredential(
      verificationId: _verificationId,
      smsCode: _smsController.text,
    );
    try{
      firebaseUser =
        (await _auth.signInWithCredential(credential)).user;
    final FirebaseUser currentUser = await _auth.currentUser();
    assert(firebaseUser.uid == currentUser.uid);
      if (firebaseUser != null) {
.....

      } else {

        _message = 'Sign in failed';
        showErrorDialog();
      }

    }catch (e){
      showErrorDialog();
    }
    setState(() {
      isLoading=false;
    });
  }

Answer 1

对，尽管timeout属性是60S。但在收到验证码并立即粘贴代码后，error_session_expired喜欢你。注意：只在安卓系统上，只收到几个电话号码。

Answer 2

不确定您的问题，但它显示:ERROR_SESSION_EXPIRED,sms代码已过期，并且在_auth.verifyPhoneNumber()中，您的超时持续时间相当短。试试60秒。

await _auth.verifyPhoneNumber(
        phoneNumber: '+91${_phoneNumberController.text}',
        timeout: Duration(seconds: 60),
        verificationCompleted: verificationCompleted,
        verificationFailed: verificationFailed,
        codeSent: codeSent,
        codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);

如果这不能帮你看看文件。
