使用NInject的API应用程序无法在IIS上运行，它仅适用于调试器Visual Studio

  经过一番大研究后我找到了答案！这个答案适用于 API Application with NInject, Leppie是对的问题是 Dependency Injection Configuration.

  首先我必须清理从 NuGet 安装的数据包，我不得不用这些数据包重新安装 Ninject .

  • Ninject

  • Ninject.web.WebApi

  • Ninject.web.WebApi.WebHost - 我错过了这个， this is required for IIS support

  • Ninject.MVC3

  • Ninject.web.Common

  • Ninject.web.Common.WebHost - 将此版本更新为最新版本（3.2.3）， this is required for IIS support

  之后检查你的类 NInjectWebCommon.cs ，在名为 CreateKernel() 的方法中，我有这一行

  GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
  

  你需要删除它，因为这将抛出

  使用从ModelValidatorProvider到NinjectDefaultModelValidatorProvider的绑定激活ModelValidatorProvider时出错

  如果一切都好！您的应用程序将在 IIS Server 上运行 .

  这些文件是我在App_Start文件夹中的NInject的最后一个配置

  NinjectWebCommon.cs

  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>();
  
              RegisterServices(kernel);
  
             // GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(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.BindFilter<ApiAuthorizationFilter>(FilterScope.Controller, 0).WhenControllerHas<ApiAuthorizationFilter>();
  
          NInjectHelper.SetupKernel(kernel);
          kernel.Bind<IEncryptionSystemService>().To<EncryptionSystemService>();
          kernel.Bind<IUserService>().To<UserService>();
          kernel.Bind<IRoleService>().To<RoleService>();
          kernel.Bind<IStatusService>().To<StatusService>();
          kernel.Bind<ICardService>().To<CardService>();
          kernel.Bind<ICardTypeService>().To<CardTypeService>();
  
  
      }
  
  }
  

  NinjectResolver.cs

  public class NinjectResolver : NinjectScope, IDependencyResolver
  {
      private IKernel _kernel;
  
      public NinjectResolver(IKernel kernel)
          : base(kernel)
      {
          _kernel = kernel;
      }
  
      public IDependencyScope BeginScope()
      {
          return new NinjectScope(_kernel.BeginBlock());
      }
  }
  

  NinjectScope.cs

  public class NinjectScope : IDependencyScope
  {
      protected IResolutionRoot resolutionRoot;
  
      public NinjectScope(IResolutionRoot kernel)
      {
          resolutionRoot = kernel;
      }
  
      public object GetService(Type serviceType)
      {
          IRequest request = resolutionRoot.CreateRequest(serviceType, null, new Parameter[0], true, true);
          return resolutionRoot.Resolve(request).SingleOrDefault();
      }
  
      public IEnumerable<object> GetServices(Type serviceType)
      {
          IRequest request = resolutionRoot.CreateRequest(serviceType, null, new Parameter[0], true, true);
          return resolutionRoot.Resolve(request).ToList();
      }
  
      public void Dispose()
      {
          IDisposable disposable = (IDisposable)resolutionRoot;
          if (disposable != null) disposable.Dispose();
          resolutionRoot = null;
      }
  }
  

  IMPORTANT! For SQL Server Users 正如你在我的 ApiFilterConfiguration 上看到的那样我有这一行 AuthorizationResult result = userService.LoginUser(model); 这个 userService 是我用方法创建的类 LoginUser(model) 这个方法从 Request Headers 获取一个模型并转到 SQL SERVER 以验证用户是否存在 .

  如果你用我的默认配置安装 SQL Server ，也许你有另一个问题抛出 Null reference after a consult ，请查看这个主题 Login failed for user IIS APPPOOL\AppPool4.5 or APPPOOL\ASP.NET 也许你需要在 SQLSERVER 上为 IIS 创建一个登录名
