定制路由asp.net mvc 3问题。

I want that in my action method, my Request.Url.Host should be available. However I don't want to set it in routedata because it will be visible to the user in the url. How can I accomplish this such that Request.Url.Host is available in my domain name variabele but now shown to the user in url? I tried adding it to Request.Form.Add("domain",Request.Url.Host) but it doesn't work because Request.Form is readonly collection.

我想要在action方法中，也就是request。url中。主持人应该是可用的。但是，我不希望在routedata中设置它，因为用户可以在url中看到它。如何完成这个请求。url。主机在我的域名中是可用的，但是现在显示给用户在url?我尝试将它添加到Request. form . add(“domain”、Request. url . host)中，但由于请求而无法工作。形式是只读的。

eg:

例如:

public ActionResult Foo(string domain, int id) //id is the standard routedata that you get from url.
{
    ..//code
}

What is the best I can do? I don't want to do Request.Url.Host in every action method so I am trying this approach.

我能做的最好的事是什么?我不想做request。url。在每个动作方法中都有主机，所以我正在尝试这种方法。

I tried to do this:

我试着这么做:

public class MyRoute : Route
    {
        #region '----- Method(s) -----'
        public MyRoute(string url, object defaults)
            : base(url, new RouteValueDictionary(defaults), new MvcRouteHandler())
        { }

        public override RouteData GetRouteData(HttpContextBase httpContext)
        {
            RouteData routeData = base.GetRouteData(httpContext);

            string domain = httpContext.Request.Url.Host;

            routeData.DataTokens["domain"] = domain;

            return routeData;
        }
        #endregion
    }

But my domain variable in my action method comes null.

但是我的action方法中的定义域变量是空的。

Thanks.

谢谢。

EDIT: Complete rewrite:

编辑:完全重写:

You should add your custom data to routeData.Values instead of routeData.DataTokens.

您应该向routeData添加自定义数据。值而不是routeData.DataTokens。

public class MyRoute : Route
{
    #region '----- Method(s) -----'
    public MyRoute(string url, object defaults)
        : base(url, new RouteValueDictionary(defaults), new MvcRouteHandler())
    { }

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        RouteData routeData = base.GetRouteData(httpContext);

        string domain = httpContext.Request.Url.Host;

        routeData.Values["domain"] = domain;

        return routeData;
    }
    #endregion
}

And registering your MyRoute route (MVC uses the first matching route so it should go first):

注册你的MyRoute (MVC使用第一个匹配的路径，所以应该先去):

routes.Add(new MyRoute("{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional }));
