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);
}
}
}
控制器
[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();
}
}
}

使用本文作为参考
Custom Validation in ASP.NET Web API with FluentValidation
您似乎已完成参考文章中的大部分工作。
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",
routeTemplate: "{action}/{id}",
defaults: new { controller = "Menu", id = RouteParameter.Optional}
);
//FluentValidation
FluentValidationModelValidatorProvider.Configure(config);
}
}
FluentValidation会自动将其错误插入ModelState
。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.");
}
}
