放大：颤振：auth_cognito：InvalidParameterException

Question

我正在使用 Flutter 开发移动应用程序。 我不知道如何解决这个问题。 我正在使用 AWS Cognito 进行用户验证

这是我的代码

void _signUp() {
    final username = _usernameController.text.trim();
    final password = _passwordController.text.trim();
    final passwordConfirm = _passwordConfirmController.text.trim();
    final email = _emailController.text.trim();
    final gender = _isGenderSelected[0] == true ? 'male' : 'female';
    final birthMonth = _birthMonthController!.length <= 1 ? '0' + _birthMonthController! : _birthMonthController!;
    final birthDay = _birthDayController!.length <= 1 ? '0' + _birthDayController! : _birthDayController!;
    final birthdate = '$birthMonth/$birthDay/$_birthYearController';

    print('username: $username');
    print('password: $password');
    print('password confirm: $passwordConfirm');
    print('email: $email');
    print('gender: $gender');
    print('birthdate: $birthdate');

    if (password == passwordConfirm) {
      final credentials = SignUpCredentials(
          username: username,
          password: password,
          email: email,
          gender: gender,
          birthdate: birthdate
      );
      widget.didProvideCredentials(credentials);
    }
    else
      print('Password does not match');
  }

这是我在运行控制台中遇到的错误

Answer 1

您提供的生日：

生日：1997 年 2 月 11 日

与该属性的 Cognito 正则表达式模式不匹配：

^[\p{L}\p{M}\p{N}.-]+(:[\p{L}\p{M}\p{N}. -]+)*$

您应该更改日期格式，或更改正则表达式。
