  如何通过URL获得的RouteData？

 公众覆盖的RouteData GetRouteData（HttpContextBase的HttpContext）
        {

            变种指数= url.IndexOf（。）;            如果（指数℃下）

            {
                VAR的RouteData =新的RouteData（这一点，新MvcRouteHandler（））;
                    routeData.Values​​.Add（控制器，业务）;
                    routeData.Values​​.Add（行动，显示）;
                    routeData.Values​​.Add（ID，子域）;
                返回的RouteData;
            }            如果（子域==M）
            {
                VAR的RouteData =新的RouteData（这一点，新MvcRouteHandler（））;

我的问题是，当我访问 xyz.mydomain.com 它总是被重新路由到 xyz.mydomain.com/Business/Display/xyz 。这是$ P $从去 xyz.mydomain.com/Overview ，因为它是拿起子和重定向pventing我。

我一直在使用如果语句，以确定是否指定了控制器尝试，但似乎没有任何工作。有什么建议？

解决方案

以防万一别人需要的答案，这是我的解决方案...

在 substrings.Length＆GT; = 3 是一个控制器，然后一个动作，使更改为2，如果你只需要一个控制器：

 公众覆盖的RouteData GetRouteData（HttpContextBase的HttpContext）
            {
                VAR主机= httpContext.Request.Headers [HOST];
                VAR URL = httpContext.Request.RawUrl;
                正则表达式的regex ​​=新的正则表达式（/）;
                字符串[] =子regex.Split（URL）;
                如果（substrings.Length＆GT; = 3）
                {
                    返回null;
                }
                变种指数= host.IndexOf（。）;
                如果（指数℃下）
                {
                    返回null;
                }                VAR子域= host.Substring（0，指数）;                如果（子域=WWW＆放大器;！＆安培;！子域=M）
                {
                    VAR的RouteData =新的RouteData（这一点，新MvcRouteHandler（））;
                        routeData.Values​​.Add（控制器，业务）; //业大User1Controller类
                        routeData.Values​​.Add（行动，显示）; //转到上User1Controller Index操作
                        routeData.Values​​.Add（ID，子域）;
                    返回的RouteData;
                }                如果（子域==M）
                {
                    VAR的RouteData =新的RouteData（这一点，新MvcRouteHandler（））;
                    routeData.Values​​.Add（控制器，手机）; //业大User2Controller类
                    routeData.Values​​.Add（行动，指数）; //转到上User2Controller Index操作                    返回的RouteData;
                }
                返回null;
            }

How to get RouteData by URL?

public override RouteData GetRouteData(HttpContextBase httpContext)
        {
            var url = httpContext.Request.Headers["HOST"];
            var index = url.IndexOf(".");

            if (index < 0)
                return null;

            var subDomain = url.Substring(0, index);

            if (subDomain != "www" && subDomain != "m")
            {
                var routeData = new RouteData(this, new MvcRouteHandler());
                    routeData.Values.Add("controller", "Business"); 
                    routeData.Values.Add("action", "Display"); 
                    routeData.Values.Add("id", subDomain);
                return routeData;
            }

            if (subDomain == "m")
            {
                var routeData = new RouteData(this, new MvcRouteHandler());
                routeData.Values.Add("controller", "Mobile"); 
                routeData.Values.Add("action", "Index"); 

                return routeData;
            }

            return null;
        }

My problem is that when I access xyz.mydomain.com it is always rerouted to xyz.mydomain.com/Business/Display/xyz. This is preventing me from going to xyz.mydomain.com/Overview as it's picking up the subdomain and redirecting.

I have tried using if statements to determine if a controller is specified, but nothing seems to work. Any suggestions?

解决方案

Just in case anyone else needs an answer this was my solution...
The substrings.Length >= 3 is for a controller then an action so change to 2 if you only need a controller :

public override RouteData GetRouteData(HttpContextBase httpContext)
            {
                var host = httpContext.Request.Headers["HOST"];
                var url = httpContext.Request.RawUrl;
                Regex regex = new Regex("/");
                string[] substrings = regex.Split(url);
                if (substrings.Length >= 3)
                {
                    return null;
                }
                var index = host.IndexOf(".");
                if (index < 0)
                {
                    return null;
                }

                var subDomain = host.Substring(0, index);

                if (subDomain != "www" && subDomain != "m")
                {
                    var routeData = new RouteData(this, new MvcRouteHandler());
                        routeData.Values.Add("controller", "Business"); //Goes to the User1Controller class
                        routeData.Values.Add("action", "Display"); //Goes to the Index action on the User1Controller
                        routeData.Values.Add("id", subDomain);
                    return routeData;
                }

                if (subDomain == "m")
                {
                    var routeData = new RouteData(this, new MvcRouteHandler());
                    routeData.Values.Add("controller", "Mobile"); //Goes to the User2Controller class
                    routeData.Values.Add("action", "Index"); //Goes to the Index action on the User2Controller

                    return routeData;
                }
                return null;
            }
