我正在尝试在Flutter应用程序中实现Firebase电话身份验证,我使用了以下软件包:Firebase_coreFirebase_auth,这是我使用d的代码:

          FirebaseAuth _auth = FirebaseAuth.instance;
          _auth.verifyPhoneNumber(
              phoneNumber: '+2$mobile',
              timeout: Duration(seconds: 60),
              verificationCompleted: (AuthCredential authCredential){
                var _credential = PhoneAuthProvider.credential(verificationId: actualCode, smsCode: smsCodeController.text);
                _auth.signInWithCredential(_credential).then((UserCredential result) async {
                  pr.hide();
                  setState(() {
                    status = 'Authentication successful';
                  });
//The rest of my success code
                }).catchError((e){
                  print(e);
                  Navigator.of(context).pushAndRemoveUntil(
                      MaterialPageRoute(
                          builder: (context) => Welcome()),
                          (Route<dynamic> route) => false);                
};
              },
              verificationFailed: (FirebaseAuthException  authException){
                print(authException.message);
              },
              codeSent: (String verificationId, [int forceResendingToken]){
                setState(() {
                  actualCode = verificationId;
                  status = 'Code sent';
                });
              },
              codeAutoRetrievalTimeout: (String verificationId){
                verificationId = verificationId;
                print(verificationId);
                setState(() {
                  status = 'Auto retrieval timeout';
                });
              },
              );

但是我总是会收到此错误:

[firebase_auth/invalid-verification-id] The verification ID used to create the phone auth credential is invalid.

有帮助吗?

答案 0 :(得分:1)

我不确定为什么存在此行:

var _credential = PhoneAuthProvider.credential(verificationId: actualCode, smsCode: smsCodeController.text);

您已经从参数authCredential中获得了凭据,因此请使用该凭据登录,因为它是有效的。

verifyPhoneNumber方法在FirebaseAuth中的工作方式如下:

  • verificationFailed:回调验证时抛出的所有错误
  • verificationCompleted:如果不需要验证短信(Google知道它是有效的电话号码)
  • codeSent:发送代码时触发,此功能是您让用户输入短信代码并使用提供的AuthCredential和代码创建verificationId的功能短信代码。
