我使用Castle.windsor和owin在webapi2中进行了一些DI工作.这是相关代码：

[assembly: OwinStartup(typeof(Bla.Startup))]
    namespace Bla
    {
        public class Startup
        {
            public void Configuration(IAppBuilder app)
            {
                //...  
                var container = new WindsorContainer().Install(new ControllerInstaller());
                var httpDependencyResolver = new WindsorHttpDependencyResolver(container);
                config.DependencyResolver = httpDependencyResolver;
                //...
            }
    }

    public class ControllerInstaller : IWindsorInstaller
    {
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(AllTypes.FromThisAssembly()
            .Pick().If(t => t.Name.EndsWith("Controller"))
            .Configure(configurer => configurer.Named(configurer.Implementation.Name))
            .LifestylePerWebRequest());

            //...
        }
    }

    internal class WindsorDependencyScope : IDependencyScope
    {
        private readonly IWindsorContainer _container;
        private readonly IDisposable _scope;

        public WindsorDependencyScope(IWindsorContainer container)
        {
            if (container == null)
            {
            throw new ArgumentNullException("container");
            }

            _container = container;
            _scope = container.BeginScope();
        }

        public object GetService(Type t)
        {
            return _container.Kernel.HasComponent(t)
            ? _container.Resolve(t) : null;
        }

        public IEnumerable<object> GetServices(Type t)
        {
            return _container.ResolveAll(t)
            .Cast<object>().ToArray();
        }

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

    internal sealed class WindsorHttpDependencyResolver : IDependencyResolver
    {
        private readonly IWindsorContainer _container;

        public WindsorHttpDependencyResolver(IWindsorContainer container)
        {
            if (container == null)
            {
            throw new ArgumentNullException("container");
            }

            _container = container;
        }

        public object GetService(Type t)
        {
            return _container.Kernel.HasComponent(t)
             ? _container.Resolve(t) : null;
        }

        public IEnumerable<object> GetServices(Type t)
        {
            return _container.ResolveAll(t)
            .Cast<object>().ToArray();
        }

        public IDependencyScope BeginScope()
        {
            return new WindsorDependencyScope(_container);
        }

        public void Dispose()
        {
        }
    }

owin的一大优点是它删除了system.web的依赖项.这允许从其他方面实施相当有效的(在内存中？)集成测试.我面临的问题是该行：

config.DependencyResolver = httpDependencyResolver;

引入系统依赖.因此,当我尝试运行像这样的简单测试时：

private TestServer _server;

    [TestFixtureSetUp]
    public void FixtureInit()
    {
        _server = TestServer.Create<Startup>();
    }

    [Test]
    public voidSomeTest()
    {
        using (var server = TestServer.Create<Startup>())
        {
        HttpResponseMessage response = server.HttpClient.GetAsync("/api/bladibla/test").Result;

        // ...
        }
    }

我得到：

{"Looks like you forgot to register the http module Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule\r\nTo fix this add\r\n<add name=\"PerRequestLifestyle\" type=\"Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor\" />\r\nto the <httpModules> section on your web.config.\...

我可以在测试项目的app.config中注册什么吗？任何反馈将非常欢迎.

PS：

我尝试添加：

<system.web>
    <httpModules>
      <add name="PerRequestLifestyle" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor" />
    </httpModules>
  </system.web>
  <system.webServer>
    <modules>
      <add name="PerRequestLifestyle" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor" />
    </modules>
  </system.webServer>

到app.config失败.

PPS：

好的,如果我更改：

container.Register(AllTypes.FromThisAssembly()
                .Pick().If(t => t.Name.EndsWith("Controller"))
                .Configure(configurer => configurer.Named(configurer.Implementation.Name))
                .LifestylePerWebRequest());

至：

container.Register(AllTypes.FromThisAssembly()
                .Pick().If(t => t.Name.EndsWith("Controller"))
                .Configure(configurer => configurer.Named(configurer.Implementation.Name))
                .LifestyleTransient());

它有效,这很有意义.最大的问题是,如何根据部署环境/测试环境或测试环境来动态更改此设置.

解决方法:

{“Looks like you forgot to register the http module Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule\r\nTo fix this add\r\n\r\nto the section on your web.config….

但是您尝试注册：

PerRequestLifestyle

看到不同？ PerWebRequestLifestyle不是PerRequestLifeStyle.

看一下Mauricio Scheffer`s HybridLifeStyles,它使测试容器的设置非常简单.
