firebase - 检索 SafetyNet token : 7, Flutter 时出现问题 - Firebase Phone_Auth

Question

我正在尝试实现 firebase 提供的 phone_auth，但它会抛出这些错误并在调用 FirebaseAuth.instance.verifyPhoneNumber() 时强制关闭。

这是我的代码，当从用户那里获取电话号码后按下按钮时，我正在调用 verifyPhoneNumber()。

String phoneNumber, verificationId;
String otp, authStatus = "";

Future<void> verifyPhoneNumber(BuildContext context) async {
await FirebaseAuth.instance.verifyPhoneNumber(
  phoneNumber: phoneNumber,
  timeout: const Duration(seconds: 15),
  verificationCompleted: (AuthCredential authCredential) {
    setState(() {
      authStatus = "Your account is successfully verified";
    });
  },
  verificationFailed: (FirebaseAuthException authException) {
    setState(() {
      authStatus = "Authentication failed";
    });
  },
  codeSent: (String verId, [int forceCodeResent]) {
    verificationId = verId;
    setState(() {
      authStatus = "OTP has been successfully send";
    });
    otpDialogBox(context).then((value) {});
  },
  codeAutoRetrievalTimeout: (String verId) {
    verificationId = verId;
    setState(() {
      authStatus = "TIMEOUT";
    });
  },
);
}

Future<void> verifyPhoneNumber(BuildContext context) async {
await FirebaseAuth.instance.verifyPhoneNumber(
  phoneNumber: phoneNumber,
  timeout: const Duration(seconds: 15),
  verificationCompleted: (AuthCredential authCredential) {
    setState(() {
      authStatus = "Your account is successfully verified";
    });
  },
  verificationFailed: (FirebaseAuthException authException) {
    setState(() {
      authStatus = "Authentication failed";
    });
  },
  codeSent: (String verId, [int forceCodeResent]) {
    verificationId = verId;
    setState(() {
      authStatus = "OTP has been successfully send";
    });
    otpDialogBox(context).then((value) {});
  },
  codeAutoRetrievalTimeout: (String verId) {
    verificationId = verId;
    setState(() {
      authStatus = "TIMEOUT";
    });
  },
);
}

otpDialogBox(BuildContext context) {
return showDialog(
    context: context,
    barrierDismissible: false,
    builder: (BuildContext context) {
      return new AlertDialog(
        title: Text('Enter your OTP'),
        content: Padding(
          padding: const EdgeInsets.all(8.0),
          child: TextFormField(
            decoration: InputDecoration(
              border: new OutlineInputBorder(
                borderRadius: const BorderRadius.all(
                  const Radius.circular(30),
                ),
              ),
            ),
            onChanged: (value) {
              otp = value;
            },
          ),
        ),
        contentPadding: EdgeInsets.all(10.0),
        actions: <Widget>[
          FlatButton(
            onPressed: () {
              Navigator.of(context).pop();
              signIn(otp);
            },
            child: Text(
              'Submit',
            ),
          ),
        ],
      );
    });
}

Future<void> signIn(String otp) async {
await FirebaseAuth.instance
    .signInWithCredential(PhoneAuthProvider.credential(
  verificationId: verificationId,
  smsCode: otp,
));
}

这已经困扰了我近 3 天了。
任何帮助将不胜感激。

确保您已启用 Android Device Check API并且您已将 SHA256 添加到 Firebase 控制台。
