如何使用 FluentValidation 创建强密码？

Question

我正在使用 FluentValidation 设计用户注册屏幕。

我想建立一个控制机制，提供有关所有步骤的信息，如下所示。

我尝试过的代码；

RuleFor(p => p.Password).Matches(@"[A-Z]+").WithMessage("Your password must contain at least one uppercase letter.");
        RuleFor(p => p.Password).Matches(@"[a-z]+").WithMessage("Your password must contain at least one lowercase letter.");
        RuleFor(p => p.Password).Matches(@"[0-9]+").WithMessage("Your password must contain at least one number.");
        RuleFor(x => x.Password).Matches(@"[\!\?\*\.]*$").WithMessage("Your password must contain at least one (!? *.).");

但我无法达到我想要的结果。我还查看了 FluentValidation 文档，但没有看到任何有用的示例。

如果您有帮助，我会很高兴。

谢谢。

请参考以下示例：

public class Login
    { 
        public string Password { get; set; }
    }


     public class PassWordValidator : AbstractValidator<Login>
        {
            public PassWordValidator()
            {
                RuleFor(p => p.Password).NotEmpty().WithMessage("Your password cannot be empty")
                    .MinimumLength(8).WithMessage("Your password length must be at least 8.")
                    .MaximumLength(16).WithMessage("Your password length must not exceed 16.")
                    .Matches(@"[A-Z]+").WithMessage("Your password must contain at least one uppercase letter.")
                    .Matches(@"[a-z]+").WithMessage("Your password must contain at least one lowercase letter.")
                    .Matches(@"[0-9]+").WithMessage("Your password must contain at least one number.")
                    .Matches(@"[\!\?\*\.]+").WithMessage("Your password must contain at least one (!? *.).");
            }
        }

行动：

 [HttpPost]
        public IActionResult TestPassword(Login model)
        {
            PassWordValidator _validator = new PassWordValidator();
            var validResult = _validator.Validate(model);
            if (!validResult.IsValid)
            {
                return BadRequest(validResult.Errors);
            }
            return Ok();
        }
