MVC中的响应永久重定向未发出301或未更改URL [英] Response Permanent Redirect in MVC not issuing 301 or changing URL

问题描述

我要将旧的ASP.NET Web窗体站点转换为ASP.NET MVC5.我想对旧页面URL发出永久重定向.

I am converting an old ASP.NET web forms site to ASP.NET MVC 5. I would like to issue permanent redirects for the old page URLs.

这就是我所做的-

RouteConfig.cs:

RouteConfig.cs:

routes.MapRoute("About_old", 
      "About/About.aspx", 
      new { controller = "Home", action = "About_old" });

HomeController.cs:

HomeController.cs:

public ActionResult About_old()
{
   return new RedirectResult("/About", true);

   // I've also tried 
   // return RedirectToActionPermanent("About"); 
   // return RedirectPermanent("/About");
}

所有尝试都会加载正确的/About视图，但是URL不会更改，并且在响应中看不到301代码.换句话说，URL是"localhost/About/About.aspx"，我希望它是"localhost/About"

All attempts load the correct /About view, however the URL does not change, and I do not see a 301 code in the response. In other words, the URL is "localhost/About/About.aspx" and I expect it to be "localhost/About"

我在哪里都看不到301，并且URL保持不变.我必须认为这与我在RouteConfig.cs中映射旧aspx页面的路由有关，因为所有操作方法都具有相同的结果. 注意我在下面放置了一个使用global.asax的解决方案，但是我希望它可以像上面所尝试的那样工作，因此我没有接受我的回答.

Nowhere do I see a 301 and the URL does not change. I have to think this has to do with how I am mapping the route of the old aspx page in RouteConfig.cs as all action methods have the same results. NOTE I have put a solution using global.asax below, however I would prefer it to work as I am attempting above, so I have not accepted my answer.

我是在做错什么还是只是错过了什么?如何获得301签发和更改URL的地址?

Am I doing something wrong or just missing something? How do I get the 301 to issue and URL to change?

推荐答案

这是我的解决方案(Global.asax)

Here is my solution (Global.asax)

protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e)
        {
            string currentUrl = HttpContext.Current.Request.Path.ToLower();
            if (currentUrl.EndsWith("/about/about.aspx"))
            {
                Response.Status = "301 Moved Permanently";
                Response.AddHeader("Location", "/About");
                Response.End();
            }
        }
