Asp.net MVC 4 RedirectToAction - prePEND域 [英] Asp.net MVC 4 RedirectToAction - prepend domain

问题描述

我需要prePEND域在RedirectToAction进行重定向，所以它相对的不是，但绝对URL。这怎么可能实现呢？

I need to prepend a domain to the redirect performed in RedirectToAction, so it's not relative, but an absolute url. How can this be accomplished?

编辑：我要补充一点的详细信息：
这是一个多租户应用程序，允许为客户设置proxydomains。所以，我需要所有的URL要经过代理。因此，一个actionredirect，这将是： http://domainX.com/Question/$p$pview/ 640328 需要通过 http://domainY.com/SUBDOMAIN/Question / preVIEW / 640328

I'll add a bit more information: It's a multitenant application that allows for clients to setup proxydomains. So I need all the urls to go through the proxy. So an actionredirect that would be: http://domainX.com/Question/Preview/640328 needs to go through http://domainY.com/SUBDOMAIN/Question/Preview/640328

推荐答案

这不能使用它自己RedirectToAction完成。但是， UrlHelper.RouteUrl方法可用于产生使用特定的主机名绝对URL。

This can't be done using RedirectToAction on it's own. However, the UrlHelper.RouteUrl method can be used to generate absolute URLs using a specific host name.

您只需要使用UrlHelper.RouteUrl，然后使用Redirect方法执行重定向生成的URL。

You simply need to generate the URL using UrlHelper.RouteUrl, then perform the redirect using the Redirect method.

如果您知道路由名称，使用类似以下内容：

If you know the route name, use something like the following:

var routeValues = new RouteValueDictionary(new { id = 12345 });
string url = Url.RouteUrl("Products.Show", routeValues, "http", "www.domainname1.com");
return Redirect(url);

如果你想生成基于控制器名称和动作的URL，使用以下命令：

If you want to generate the URL based on the controller name and action, use the following:

var routeValues = new RouteValueDictionary(
    new { controller = "Products", action = "Show", id = 12345 });
string url = Url.RouteUrl(null, routeValues), "http", "www.domainname1.com");
return Redirect(url);

上面的每条记录将重定向到一个绝对URL如 http://www.domainname1.com/products / 12345

注意UrlHelper的一个实例，通过内置的 Controller.Url 属性）。

Note that an instance of UrlHelper is available within controller code via the built-in Controller.Url property).
