使用Ninject和Ninject.Web.Api进行Web API Api 2在ASP.NET MVC中不起作用5

Question

我正在开发一个Asp.NET MVC项目。我的项目也有web api。我在Visual Studio 3中使用ASP.NET MVC5和Web Api 2.我正在使用ninject进行依赖注入。我知道ninject for web不适用于Web Api 2.所以我尝试使用Ninject进行Web Api。请参阅下面的我的场景。

我使用的NuGet

然后我安装Ninject.Web包管理

然后在NinjectWebCommon，我添加使用NuGet包管理器安装用于网络API 2包ninject这行在RegisterServices

private static void RegisterServices(IKernel kernel) 
     { 
      System.Web.Http.GlobalConfiguration.Configuration.DependencyResolver = new Ninject.WebApi.DependencyResolver.NinjectDependencyResolver(kernel); 
      kernel.Bind<ICategoryRepo>().To<CategoryRepo>(); 
     }  

这是我的全NinjectWebCommon类注册一个依赖

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(PatheinFashionStore.Web.App_Start.NinjectWebCommon), "Start")] 
[assembly: WebActivatorEx.ApplicationShutdownMethodAttribute(typeof(PatheinFashionStore.Web.App_Start.NinjectWebCommon), "Stop")] 

namespace PatheinFashionStore.Web.App_Start 
{ 
    using System; 
    using System.Web; 

    using Microsoft.Web.Infrastructure.DynamicModuleHelper; 

    using Ninject; 
    using Ninject.Web.Common; 
    using PatheinFashionStore.Domain.Abstract; 
    using PatheinFashionStore.Domain.Concrete; 

    public static class NinjectWebCommon 
    { 
     private static readonly Bootstrapper bootstrapper = new Bootstrapper(); 

     /// <summary> 
     /// Starts the application 
     /// </summary> 
     public static void Start() 
     { 
      DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule)); 
      DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule)); 
      bootstrapper.Initialize(CreateKernel); 
     } 

     /// <summary> 
     /// Stops the application. 
     /// </summary> 
     public static void Stop() 
     { 
      bootstrapper.ShutDown(); 
     } 

     /// <summary> 
     /// Creates the kernel that will manage your application. 
     /// </summary> 
     /// <returns>The created kernel.</returns> 
     private static IKernel CreateKernel() 
     { 
      var kernel = new StandardKernel(); 
      try 
      { 
       kernel.Bind<Func<IKernel>>().ToMethod(ctx =>() => new Bootstrapper().Kernel); 
       kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>(); 
       System.Web.Http.GlobalConfiguration.Configuration.DependencyResolver = new Ninject.WebApi.DependencyResolver.NinjectDependencyResolver(kernel); 
       RegisterServices(kernel); 
       return kernel; 
      } 
      catch 
      { 
       kernel.Dispose(); 
       throw; 
      } 
     } 

     /// <summary> 
     /// Load your modules or register your services here! 
     /// </summary> 
     /// <param name="kernel">The kernel.</param> 
     private static void RegisterServices(IKernel kernel) 
     { 

      kernel.Bind<ICategoryRepo>().To<CategoryRepo>(); 
     }   
    } 
} 

这是我的控制器

public class HomeController : Controller 
    { 
     private ICategoryRepo categoryRepo; 

     public HomeController(ICategoryRepo categoryRepoParam) 
     { 
      this.categoryRepo = categoryRepoParam; 
     } 

     public ActionResult Index() 
     { 
      return View(); 
     } 
} 

后来，当我跑我的代码，它给我这个错误

这是另外的

但是当我访问apiController时，它正在工作。

这里是我的网页API控制器

public class TestController : ApiController 
    { 
     private ICategoryRepo categoryRepo; 

     public TestController(ICategoryRepo categoryRepoParam) 
     { 
      this.categoryRepo = categoryRepoParam; 
     } 

     public string Get() 
     { 
      this.categoryRepo.Create(); 
      return "OK"; 
     } 
    } 

所以，我发现了什么是它正在为网络API，但不工作的web项目。我在同一个项目中使用了两个。

您需要与DependencyResolver一起安装Ninject.MVC5和设置DependencyResolver为MVC为的WebAPI

// Web Api 
System.Web.Http.GlobalConfiguration.Configuration.DependencyResolver = new Ninject.WebApi.DependencyResolver.NinjectDependencyResolver(kernel); 

// MVC 
System.Web.Mvc.DependencyResolver.SetResolver(new Ninject.Web.Mvc.NinjectDependencyResolver(kernel));
