路由与MVC3一个子 [英] Routing a subdomain with MVC3

问题描述

我想创造一些我的客户的服务，将让他们有一个MVC3网站，我已经建立有自己的网页。

I am wanting to create a service for some of my customers that will allow them to have there own webpage on a MVC3 site I have built.

我想一个企业要能够有一个网址，看起来像www.BusinessName.mydomain.com

I want a business to be able to have a url that looks like www.BusinessName.mydomain.com

是否有可能创建MVC3内的路线，让我做到这一点？

Is it possible to create a route within MVC3 that will allow me to do this?

感谢您的帮助。

好了，所以我觉得我已经进一步得到了一点。

Ok so I think I have gotten a little further.

理想我希望能够有IIS中的子域通配符但是从我做它看起来这是不可能的研究。

Ideally I want to be able to have a wildcard for the subdomain in IIS however from the research I have done it looks like this isn't possible.

我手动添加www.mycompany.mydomain.com到IIS和更新我的global.ascx包含此

I have manually added www.mycompany.mydomain.com into IIS and updated my global.ascx to contain this

   public class SubDomainRoute : RouteBase
    {

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

            var subDomain = Helpers.Helpers.GetSubDomain(url);
            if (subDomain==null)
                return null;
            var routeData = new RouteData(this, new MvcRouteHandler());

            switch (subDomain)
            {
                case "mycompany":
                    routeData.Values.Add("controller", "SubDomain");
                    routeData.Values.Add("action", "Index");
                    break;
                default:
                    routeData.Values.Add("controller", "Home");
                    routeData.Values.Add("action", "Index");
                    break;
            }

            return routeData;
        }

        public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
        {
            return null;
        }
    }

所以，现在我可以浏览www.mycompanyname.mydomain.com和正确的控制器被装入。

So now I can browse www.mycompanyname.mydomain.com and the correct controller is loaded.

我现在有2个问题。

如果我浏览到www.mistake.mydomain.com我得到一个502错误。如果www.mistake.mydomain.com没有找到什么我可以在IIS做重定向到www.mydomain.com？

If I browse to www.mistake.mydomain.com I get a 502 error. What can I do in IIS to redirect to www.mydomain.com if www.mistake.mydomain.com isn't found?

一旦我能浏览到www.mycompanyname.mydomain.com所有的链接我的主菜单中，现在指向例如www.mycompanyname.mydomain.com/contactus这是不对的，我怎么保证菜单项不使用URL中的子？

Once I have browsed to www.mycompanyname.mydomain.com all of the links within my main menu are now pointing to e.g. www.mycompanyname.mydomain.com/contactus which is wrong, how do I ensure the menu items are not using the subdomain within the url?

推荐答案

我建议稍微不同的方法 - 唯一需要注意的是，这个网站必须在IIS中的唯一的一个。因为IIS不支持通配符主机头，它必须是默认的Web站点。

I'd suggest a slightly different approach - only caveat is that this web site must be the only one on IIS. Because IIS doesn't support wildcard host headers, it has to be Default Web site.

这样，你会得到所有的请求（包括www.mistake.mydomain.com）到应用程序的前门，你可以适当地处理它们。

This way, you will get all requests (including www.mistake.mydomain.com) to your application's front door, and you can handle them appropriately.

在你的MVC应用程序，请不要使用路由子域，使用的Application_BeginRequest。在那里，你做你有Request.Headers办[HOST]，并要将他们送他们什么。

In your MVC application, don't use routing for subdomains, use Application_BeginRequest. There you do what you have to do with Request.Headers["HOST"] and send them where you want them.

我看到它的方式，路线是为了用于路由用户当他到现场，而不是决定哪些网站的用户访问...

The way I see it, Routes are meant to be used for routing user when he gets to the site, not to decide which site user is visiting...
