如何在MVC中获得上一条路线 [英] How to get the previous route in MVC

问题描述

我的应用程序需要获取所有重定向的先前视图.我目前有一个父控制器，它将检查并获取当前视图.这很好.我如何获得以前的成绩?

My application needs to obtain the previous view on all redirects. I currently have a parent controller that will check and grabs the current view. This works fine. How do I get previous?

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    String currentView = Request.RawUrl
    //Do stuff with currentView string

    //String previousView = ......?
    //Do stuff with previousView string


    var query = db.PageRoutes.Where(a => a.RouteKey == currentView).FirstOrDefault();
    if (query != null)
    {
         ViewBag.htmlRawData = query.Results;
    }

    base.OnActionExecuting(filterContext);
}

最后，请使用:

String previousUrl = Request.UrlReferrer.AbsoluteUri;

将带回上一页，例如//localhost:53188/Help/Index，我只需要/Help/Index

will bring back the previous page like //localhost:53188/Help/Index where as I just need /Help/Index

推荐答案

String previousUrl = Request.UrlReferrer.AbsolutePath;
