FluentValidation NotEmpty和EmailAddress示例

Question

我正在使用FluentValidation和登录表单.电子邮件地址字段是

必填且必须是有效的电子邮件地址.

我希望在两种情况下都显示自定义错误消息.

我工作的代码是:

RuleFor(customer => customer.email)
    .NotEmpty()
    .WithMessage("Email address is required.");

RuleFor(customer => customer.email)
    .EmailAddress()
    .WithMessage("A valid email address is required.");

上面的代码确实有效,并显示(2)不同的错误消息.是否有更好的方法为一个字段写入多个错误消息？

更新 - 工作

每个要求工作.WithMessage 后链接和添加.

RuleFor(customer => customer.email)
    .NotEmpty()
        .WithMessage("Email address is required.")
    .EmailAddress()
        .WithMessage("A valid email address is required.");

Answer 1

您可以将它们链接在一起,因为一个原因,它被称为Fluent Validation.

RuleFor(s => s.Email).NotEmpty().WithMessage("Email address is required")
                     .EmailAddress().WithMessage("A valid email is required");
