FluentValidation NotEmpty和EmailAddress示例 [英] FluentValidation NotEmpty and EmailAddress example

问题描述

我正在使用FluentValidation和一个登录表单.电子邮件地址字段为

I am using FluentValidation with a login form. The email address field is

必需和必须是有效的电子邮件地址.

两种情况下我都想显示自定义错误消息.

I want to display a custom error message in both cases.

我正在工作的代码是:

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

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

上面的代码可以正常工作，并显示(2)条不同的错误消息. 有没有一种更好的方法可以为一个字段编写多个错误消息?

The above code does work and shows (2) different error messages. Is there a better way of writing the multiple error message for one field?

更新-工作中

绑定并在每个要求生效后添加.WithMessage .

Chaining and add .WithMessage after each requirement worked.

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

推荐答案

您可以将它们链接在一起，出于某种原因，它被称为Fluent Validation.

You can just chain them together, it's called Fluent Validation for a reason.

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