我在我的WebApi项目控制器中成功实现了FluentValidation,该控制器只有一个HttpGet方法.当我添加另一个HttpGet方法时,我将路由属性添加到两个方法中.即[Route(“Method1”)]和[Route(“Method2”)].
现在无论我是否输入任何数据,ModelState都会返回true.
这是我的代码.
WebApiConfig
public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.Filters.Add(new ValidateModelStateFilter()); //FluentValidation FluentValidationModelValidatorProvider.Configure(config); // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi",routeTemplate: "{action}/{id}",defaults: new { controller = "Menu",id = RouteParameter.Optional} ); } }
ValidateModelStateFilter
public class ValidateModelStateFilter : ActionFilterAttribute { public override void OnActionExecuting(HttpActionContext actionContext) { if (!actionContext.ModelState.IsValid) { actionContext.Response = actionContext.Request.CreateErrorResponse(HttpStatusCode.BadRequest,actionContext.ModelState); } } }
调节器
[HttpGet] [Route("Method1")] public IHttpActionResult ReadAllMenusByApplication([FromUri] ReadAllMenusByApplicationInput input) { var result = new List<ApplicationMenu>(); ... }
输入对象
using FluentValidation; using FluentValidation.Attributes; namespace MenuService.Models { [Validator(typeof(ReadAllMenusByApplicationInputValidator))] public class ReadAllMenusByApplicationInput { public ReadAllMenusByApplicationInput() { this.ApplicationName = string.Empty; } /// <summary> /// The MenuSystem name of the application /// </summary> public string ApplicationName { get; set; } } public class ReadAllMenusByApplicationInputValidator : AbstractValidator<ReadAllMenusByApplicationInput> { public ReadAllMenusByApplicationInputValidator() { RuleFor(x => x.ApplicationName).NotEmpty(); } }
}
解决方法
使用本文作为参考
Custom Validation in ASP.NET Web API with FluentValidation
检查配置顺序.
public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API configuration and services config.Filters.Add(new ValidateModelStateFilter()); // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi",id = RouteParameter.Optional} ); //FluentValidation FluentValidationModelValidatorProvider.Configure(config); } }
FluentValidation会自动将其错误插入到ModelState中.您应该包含错误消息.
public class ReadAllMenusByApplicationInputValidator : AbstractValidator<ReadAllMenusByApplicationInput> { public ReadAllMenusByApplicationInputValidator() { RuleFor(x => x.ApplicationName).NotEmpty() .WithMessage("The Application Name cannot be blank."); } }
本文的一些内容超出了您的问题范围.主要包装响应,但其他一切应该适合你.
