asp.net-mvc - 城堡 PerRequestLifestyle 无法识别

Question

城堡/温莎的新手，请多多包涵。

我目前正在使用框架System.Web.Mvc.Extensibility并且在其启动代码中，它注册了 HttpContextBase ，如下所示：

container.Register(Component.For<HttpContextBase>().LifeStyle.Transient.UsingFactoryMethod(() => new HttpContextWrapper(HttpContext.Current)));

我想做的是改变行为并将httpContextBase的生活方式改变为PerWebRequest。

所以我将代码更改为以下内容：

container.Register(Component.For<HttpContextBase>().LifeStyle.PerWebRequest.UsingFactoryMethod(() => new HttpContextWrapper(HttpContext.Current)));

但是，当我这样做时，出现以下错误：

 System.Configuration.ConfigurationErrorsException: Looks like you forgot to 
 register the http module Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule
 Add '<add name="PerRequestLifestyle" 
 type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.MicroKernel" 
 />' to the <httpModules> section on your web.config

我在下做过<system.web>，<system.webServer>但是，我仍然遇到同样的错误。有什么提示吗？

提前致谢。

每个请求添加代码块

在system.web.mvc.extensibility框架中，有一个继承自HttpApplication的类extendedMvcApplication，在Application_start方法中调用了BootStrapper.Execute()。此方法的实现如下：

public void Execute()
    {
        bool shouldSkip = false;

        foreach (IBootstrapperTask task in ServiceLocator.GetAllInstances<IBootstrapperTask>().OrderBy(task => task.Order))
        {
            if (shouldSkip)
            {
                shouldSkip = false;
                continue;
            }

            TaskContinuation continuation = task.Execute(ServiceLocator);

            if (continuation == TaskContinuation.Break)
            {
                break;
            }

            shouldSkip = continuation == TaskContinuation.Skip;
        }
    }

如您所见，它遍历 IBootStrapperTask 列表并尝试执行它们。碰巧我有一项任务在我的 mvc 应用程序中注册路由：

public class RegisterRoutes : RegisterRoutesBase
{
    private HttpContextBase contextBase;

    protected override TaskContinuation ExecuteCore(IServiceLocator serviceLocator)
    {
        contextBase = serviceLocator.GetInstance<HttpContextBase>();
        return base.ExecuteCore(serviceLocator);
    }

    protected override void Register(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });
        routes.IgnoreRoute("{*robotstxt}", new { robotstxt = @"(.*/)?robots.txt(/.*)?" });

        XmlRouting.SetAppRoutes(routes, contextBase.Server.MapPath("~/Configuration/Routes.xml"));
    }
}

您可以看到我需要 getInstance(resolve) 一个 httpcontextbase 对象，以便我可以获取 xml 文件的服务器路径。

在撰写本文时，PerWebRequest 生活方式不支持在 Application_Start() 中解析。

See issue description and discussion:

Workarounds for this particular case:

Register RegisterRoutes as an instance, explicitly passing it the current context as constructor parameter, e.g.:

container.Register(Component.For<IBootstrapperTask>()
                            .Instance(new RegisterRoutes(Context)));

Use HostingEnvironment.MapPath instead of contextBase.Server.MapPath. Want to make it mockable? Use it through a simple interface, e.g.:

interface IServerMapPath {
    string MapPath(string virtualPath);
}

class ServerMapPath: IServerMapPath {
    public string MapPath(string virtualPath) {
        return HostingEnvironment.MapPath(virtualPath);
    }
}

container.AddComponent<IServerMapPath, ServerMapPath>();

Then inject IServerMapPath into your RegisterRoutes.
