С использованием UnityContainer и Web Api. Ошибка. Убедитесь, что у контроллера есть без параметров открытый конструктор.

Question

У меня есть проект api mvc, который для некоторого метода, когда я вызываю действие. он дает мне ошибку, как это:

{ «Сообщение»: «Произошла ошибка.», «ExceptionMessage»:. "Ошибка Произошла ошибка при попытке создать контроллер типа „ReserveController“Make убедитесь, что контроллер имеет общественности без параметров конструктор "" ExceptionType. ":" System.InvalidOperationException " "StackTrace":" на System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create (HttpRequestMessage запрос, HttpControllerDescriptor controllerDescriptor , Тип controllerType) \ r \ n на System.Web.Http.Controllers.HttpControllerDescriptor.Cr eateController (HttpRequestMessage запрос) \ r \ n в System.Web.Http.Dispatcher.HttpControllerDispatcher.d__1.MoveNext() "," InnerException ": {" Сообщение ":" произошла ошибка .

Вот мой апи конфигурационный класс

public static class WebApiConfig 
    { 
     public static void Register(HttpConfiguration config) 
     { 


      var container = new UnityContainer(); 

      Jabama.Core.Services.Config.UnityConfig.RegisterTypes(container); 

      container.RegisterType<Core.Services.Search.IAutoCompoleteSearchService, Core.Services.Search.AutoCompoleteSearchService>(); 
      container.RegisterType<Core.Services.Common.IImageService, Core.Services.Common.ImageService>(); 
      container.RegisterType<Core.Services.Search.ICitySearchService, Core.Services.Search.CitySearchService>(); 
      container.RegisterType<Core.Services.ContentPanel.ICityService, Core.Services.ContentPanel.CityService>(); 

      container.RegisterType<IAuthenticationManager>(new InjectionFactory(o => new FakeOWINAuth())); 
      container.RegisterType<IDataProtectionProvider>(new InjectionFactory(o => Startup.DataProtectionProvider)); 
      container.RegisterType<Core.Services.Common.IUserManagerService, Core.Services.Common.UserManagerService>(); 

      container.RegisterType<Core.Services.FrontEnd.IOrderService, Core.Services.FrontEnd.OrderService>(); 

      container.RegisterType<Core.Services.FrontEnd.IPlaceService, Core.Services.FrontEnd.PlaceService>(); 

      CurrentUnityContainer.Container = container; 

      config.DependencyResolver = new UnityResolver(container); 



      config.Routes.MapHttpRoute(
       name: "DefaultApi", 
       routeTemplate: "api/{controller}/{id}", 
       defaults: new { id = RouteParameter.Optional } 
      ); 

      // Web API routes 
      config.MapHttpAttributeRoutes(); 
    } 
    } 

Это мой CurrentUnityContainer

internal static class CurrentUnityContainer 
    { 
     internal static IUnityContainer Container { get; set; } 
    } 

Мои UnityResolver

public class UnityResolver : IDependencyResolver 
    { 
     protected IUnityContainer container; 

     public UnityResolver(IUnityContainer container) 
     { 
      if (container == null) 
      { 
       throw new ArgumentNullException("container"); 
      } 
      this.container = container; 
     } 

     public object GetService(Type serviceType) 
     { 
      try 
      { 
       return container.Resolve(serviceType); 
      } 
      catch (ResolutionFailedException ex) 
      { 
       Elmah.ErrorSignal.FromCurrentContext().Raise(ex); 
       return null; 
      } 
     } 

     public IEnumerable<object> GetServices(Type serviceType) 
     { 
      try 
      { 
       return container.ResolveAll(serviceType); 
      } 
      catch (ResolutionFailedException) 
      { 
       return new List<object>(); 
      } 
     } 

     public IDependencyScope BeginScope() 
     { 
      var child = container.CreateChildContainer(); 
      return new UnityResolver(child); 
     } 

     public void Dispose() 
     { 
      container.Dispose(); 
     } 
    } 

и это мой ReserveContoller, которая была вызвана ошибкой в ​​нем

} 

Кто-нибудь есть какие-либо идеи относительно того, что это моя ошибка?

Спасибо.

Answer 1

Попробуйте добавить конструктор без параметров для вашего ReserveController класса ...

Что-то вроде этого:

public ReserveController() {} //parameterless constructor for Unity 

[RoutePrefix("v1/Reserve")] 
public ReserveController(IOrderService orderService, IPaymentService paymentService, ISMSService smsService, IUserManagerService userService, IEventService eventService, ITourService tourService) 
{ 

...
