c# - Umbraco 应用程序 BeginRequest 从未被解雇

Question

我想在 Umbraco 中触发 BeginRequest 事件，但它不起作用。其余代码工作正常。

public class ApplicationEventHandler : IApplicationEventHandler
{
    public void OnApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { }

    public void OnApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { }

    public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        umbracoApplication.BeginRequest += umbracoApplication_BeginRequest;

        BundleConfig.RegisterBundles(BundleTable.Bundles);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    }

    void umbracoApplication_BeginRequest(object sender, EventArgs e)
    {
        // Create HttpApplication and HttpContext objects to access
        // request and response properties.
        UmbracoApplicationBase application = (UmbracoApplicationBase)sender;
        HttpContext context = application.Context;

        if (context.Response.Cookies[Const.LANGUAGE_COOKIE_NAME] == null)
        {
            context.Response.Cookies.Add(new HttpCookie(Const.LANGUAGE_COOKIE_NAME, Thread.CurrentThread.CurrentUICulture.Name));
            return;
        }

        //cookie exists already
        else
        {
            //if no 404 
            if (UmbracoContext.Current.PublishedContentRequest != null && !UmbracoContext.Current.PublishedContentRequest.Is404)
            {
                //cookie value different than the current thread: user switched language.
                if (context.Response.Cookies[Const.LANGUAGE_COOKIE_NAME].Value != Thread.CurrentThread.CurrentUICulture.Name)
                {
                    //we set the cookie
                    context.Response.Cookies[Const.LANGUAGE_COOKIE_NAME].Value = Thread.CurrentThread.CurrentUICulture.Name;
                }
            }
        }
    } 
}

你知道为什么它不起作用吗？我正在使用 umbraco 7，本地 IIS(不是 express)，我无法在函数 umbracoApplication_BeginRequest 中记录消息。

这就是我能够在 Umbraco 7.1.2 实例中附加到 BeginRequest 的方式。首先创建一个继承自 UmbracoApplication 的新类(参见下面的示例)，然后更新您的 global.asax 以继承您的新类。

public class MyUmbracoApplication : Umbraco.Web.UmbracoApplication
{
    private void Application_BeginRequest(object sender, EventArgs e)
    {
        /*  Your code here */
    }
}
