Ninject.Web.WebApi.OwinHost v3.2.x 的 Ninject 依赖项

Question

我正在尝试在 Azure 辅助角色中注入 ApiControllers。我以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 ninjection。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？需要 Ninject 版本 ≥ 3.0.0.0 &&

我试过了

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，但是我相信我需要 owin 风格，而 SelfHost 似乎没有安装 NinjectWebCommon.cs 或同等产品。一旦成功包含 OwinHost，我不知道在哪里将 ninject 连接到工作角色中的 owin self 主机。我假设它将是脚手架。

可能不相关，但是在检查 WorkerRole 中已安装包的版本时，我注意到许多包是 IIS 特定的。 Azure WorkerRole Owin 自托管是否需要这些？特别是对于 Microsoft.AspNet.WebApi.SelfHost，我看到了以下符号，但我确实安装了 Microsoft.AspNet.WebApi.OwinSelfHost。

这是一个旧包，用于在您自己的内部托管 ASP.NET Web API 进程（在 IIS 之外）。请使用 用于新项目的 Microsoft.AspNet.WebApi.OwinSelfHost 包。

我知道这已经晚了，但我遇到了同样的问题，并通过谷歌搜索找到了这个问题。我最终通过-DependencyVersion 解决了这个问题：

Install-Package Ninject.Web.WebApi.OwinHost -DependencyVersion Highest

如果您不想更新所有依赖的 NuGet 包，我发现手动安装 Ninject.Web.WebApi.OwinHost 的所有与 Ninject 相关的依赖项，然后安装 Ninject.Web.WebApi.OwinHost 也有围绕这个问题。

Answer 2

我今天遇到了同样的问题，我通过以下方式解决了 将以下类实现添加到您的项目中

    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 中

将以下代码行添加到此方法 CreateKernel()： GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel); 所以完整的实现将是：

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;
            }
        }

我自己尝试了这段代码，它成功了
