MVC 中的响应永久重定向不发出 301 或更改 URL [英] Response Permanent Redirect in MVC not issuing 301 or changing URL

问题描述

我正在将旧的 ASP.NET Web 表单站点转换为 ASP.NET MVC 5.我想为旧页面 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");
}

所有尝试都加载了正确的/About 视图，但是 URL 没有改变，而且我在响应中没有看到 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"

我在任何地方都没有看到 301，而且 URL 没有改变.我不得不认为这与我如何在 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.注意我已经在下面使用 global.asax 提出了一个解决方案，但是我希望它像我上面尝试的那样工作，所以我没有接受我的答案.

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.

我是做错了什么还是遗漏了什么?如何让 301 发出并更改 URL?

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();
            }
        }

从这里的答案:从域到 www.domain 的全局 301 重定向
