asp.net - 从 Global.asax 中获取操作的绝对 URL 路径

Question

很抱歉问了这个基本问题。

从 Global.asax 中，我想获取 Controller 操作的绝对路径，就像我们通过调用 Response.Redirect("~/subfolder") 获得的那样> 从任何地方或从我们的 View 中调用 @Url.Content("~/controller/action")。

在我的 Global.asax 事件中，我想做这样的事情:

protected void Application_BeginRequest(object sender, EventArgs args)
{
  if ( string.Compare(HttpContext.Current.Request.RawUrl, "~/foo", true) == 0 )
    // do something

    // I'd like the "~foo" to resolve to the virtual path relative to 
    // the application root
}

这是answer for your problem

您可以像这样简单地获取 Controller 和操作名称

protected void Application_BeginRequest(object sender, EventArgs args)
{
    HttpContextBase currentContext = new HttpContextWrapper(HttpContext.Current);
    UrlHelper urlHelper = new UrlHelper(HttpContext.Current.Request.RequestContext);
    RouteData routeData = urlHelper.RouteCollection.GetRouteData(currentContext);
    string action = routeData.Values["action"] as string;
    string controller = routeData.Values["controller"] as string;

  if (string.Compare(controller, "foo", true) == 0)
    // do something

    // if the controller for current request if foo
}
