.Net Web Api中利用FluentValidate进行参数验证的方法_实用技巧_

 public class Product { public string name { get; set; } public string des { get; set; } public string place { get; set; } }

 public class ProductValidator : AbstractValidator { public ProductValidator() { RuleFor(product => product.name).NotNull().NotEmpty();//name 字段不能为null,也不能为空字符串 } }

 public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API routes ... FluentValidationModelValidatorProvider.Configure(config); } }

 public class ValidateModelStateFilter : ActionFilterAttribute { public override void OnActionExecuting(HttpActionContext actionContext) { if (!actionContext.ModelState.IsValid) { actionContext.Response = actionContext.Request.CreateErrorResponse(HttpStatusCode.BadRequest, actionContext.ModelState); } } }

 public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API configuration and services config.Filters.Add(new ValidateModelStateFilter()); // Web API routes ... FluentValidationModelValidatorProvider.Configure(config); } }

 [ValidateModelStateFilter] public class ProductController : ApiController { //具体的逻辑 }
