使用FluentValidation进行前端和服务端验证

luent Validation 翻译为：流畅验证
 
　　开源Codeplex其主页简介：该组件是一个轻量级的.NET类库，使用流畅的接口定义和lambda表达式为构建一个业务类的验证规则（A small validation library for .NET that uses a fluent interface and lambda expression for building validation rules for you business objects.）

将其应用到我们的项目中，首先新建一个业务实体类。注意需要引用 FluentValidation.dll 和 FluentValidation.Mvc;

　　[Validator(typeof(BankCardValidator))]
    public class BankCardModel
    {
        public string AccountCurrency { get; set; }
        /// <summary>
        /// 汇款单号
        /// </summary>
        public string RemitOrderNo { get; set; }

        /// <summary>
        /// 汇款交易号
        /// </summary>
        public string TradeNo { get; set; }

        /// <summary>
        /// 汇款人账户
        /// </summary>
        public string RemittorAccount { get; set; }
        /// <summary>
        /// 汇款人姓名
        /// </summary>
        public string RemittorName { get; set; }
        /// <summary>
        /// 汇款方式
        /// </summary>
        public string RemitWay { get; set; }
        /// <summary>
        /// 汇款金额
        /// </summary>
        public decimal RemitAmount { get; set; }

    }

然后是验证类

public class BankCardValidator : AbstractValidator<BankCardModel>
{
    public BankCardValidator()
    {
            RuleFor(x => x.AccountCurrency).NotEmpty().WithMessage("请输入AccountCurrency");
            RuleFor(x => x.RemitAmount).NotEmpty().WithMessage("请输入RemitAmount");
            RuleFor(x => x.RemitOrderNo).NotEmpty().WithMessage("请输入RemitOrderNo");
            RuleFor(x => x.RemittorName).NotEmpty().WithMessage("请输入RemittorName");
     }
}

如果需要在页面上使用，需要辅以 jquery.validate.min.js 和 jquery.validate.unobtrusive.js 两个js验证插件

由于其不是ASP.NET MVC的默认验证规则类库，我们就需要注册到ASP.NET MVC的验证规则库中

FluentValidationModelValidatorProvider provider = new FluentValidationModelValidatorProvider(new AttributedValidatorFactory());
ModelValidatorProviders.Providers.Add(provider);
DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

最后出来的效果就是这样哒
