我试图在Azure辅助角色中隐藏ApiControllers。我之前在同一解决方案中的asp.net mvc 5 / web api 2项目中使用相同的控制器完成了注射。此WorkerRole项目中的另一个非注入测试控制器工作并提供预期结果。
在尝试添加NuGet包Ninject.Web.WebApi.OwinHost（版本3.2.x）时，看起来该包是错误的？要求Ninject版本≥3.0.0.0＆amp;＆amp; ＆LT; 3.1.0.0
我已经尝试了
Install-Package Ninject.Web.WebApi.OwinHost -ProjectName WorkerRole1
Install-Package Ninject.Web.WebApi.OwinHost -Pre -ProjectName WorkerRole1
Install-Package Ninject.Web.WebApi.OwinHost -Version 3.2.0 -ProjectName WorkerRole1
Install-Package Ninject.Web.WebApi.OwinHost -Version 3.2.1-unstable-002 -ProjectName WorkerRole1
我能够成功添加Ninject.Web.WebApi.SelfHost，但我相信我需要Owin的味道，并且SelfHost似乎没有安装NinjectWebCommon.cs或同等版本。一旦我成功地将OwinHost包括在内，我就不知道在工作者角色中将ninject连接到owin self host的位置。我假设它将被支架化。

然而，在检查WorkerRole中已安装软件包的版本时可能无关，我注意到许多软件包是特定于IIS的。 Azure WorkerRole Owin自托管主机需要这些吗？特别是对于Microsoft.AspNet.WebApi.SelfHost我看到以下表示法，但我确实安装了Microsoft.AspNet.WebApi.OwinSelfHost。
这是一个用于托管ASP.NET Web API的旧版程序包 进程（在IIS之外）。请使用 用于新项目的Microsoft.AspNet.WebApi.OwinSelfHost包。

我知道这已经很晚了，但我遇到了同样的问题，并通过Google搜索找到了这个问题。我最终用-DependencyVersion：
Install-Package Ninject.Web.WebApi.OwinHost -DependencyVersion Highest
如果您不想更新所有依赖的NuGet包，我发现为Ninject.Web.WebApi.OwinHost手动安装所有与Ninject相关的依赖项，然后安装Ninject.Web.WebApi.OwinHost也得到了围绕这个问题。
答案 1 :(得分：0)
我今天遇到了同样的问题，我通过以下方式解决了这个问题 将以下类实现添加到项目中
public class NinjectDependencyScope : IDependencyScope
{
IResolutionRoot resolver;
public NinjectDependencyScope(IResolutionRoot resolver)
{
this.resolver = resolver;
}
public object GetService(Type serviceType)
{
if (resolver == null)
throw new ObjectDisposedException("this", "This scope has been disposed");
return resolver.TryGet(serviceType);
}
public System.Collections.Generic.IEnumerable<object> GetServices(Type serviceType)
{
if (resolver == null)
throw new ObjectDisposedException("this", "This scope has been disposed");
return resolver.GetAll(serviceType);
}
public void Dispose()
{
IDisposable disposable = resolver as IDisposable;
if (disposable != null)
disposable.Dispose();
resolver = null;
}
}
// This class is the resolver, but it is also the global scope
// so we derive from NinjectScope.
public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
{
IKernel kernel;
public NinjectDependencyResolver(IKernel kernel)
: base(kernel)
{
this.kernel = kernel;
}
public IDependencyScope BeginScope()
{
return new NinjectDependencyScope(kernel.BeginBlock());
}
}
2-然后在NinjectWebCommon
将以下代码行添加到此方法CreateKernel（）： GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver（kernel）; 所以完整的实施将是：
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
try
{
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
// Install our Ninject-based IDependencyResolver into the Web API config
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
RegisterServices(kernel);
return kernel;
}
catch
{
kernel.Dispose();
throw;
}
}
我自己尝试了这个代码并且运行成功
