本地主机上的子域名出现“Bad Request - Invalid Hostname”错误

Question

我正在使用MVC。 我想在IIS上使用本地主机测试子域。 我创建子域所做的操作如下：

1. I added a line to windows host file

   127.0.0.1       localhost
   127.0.0.1       abc.localhost
   ::1             localhost
   

2. I edited applicationhost.config as:

     <bindings>
           <binding protocol="http" bindingInformation="*:59322:localhost" />
           <binding protocol="http" bindingInformation="*:59322:abc.localhost" />
     </bindings>

3. I added following class to RouteConfig.cs :

   public class SubdomainRoute : RouteBase { public override RouteData GetRouteData(HttpContextBase httpContext) { var host = httpContext.Request.Url.Host; var index = host.IndexOf("."); string[] segments = httpContext.Request.Url.PathAndQuery.Split('/'); if (index < 0) return null; var subdomain = host.Substring(0, index); string controller = (segments.Length > 0) ? segments[0] : "Home"; string action = (segments.Length > 1) ? segments[1] : "Index"; var routeData = new RouteData(this, new MvcRouteHandler()); routeData.Values.Add("controller", controller); routeData.Values.Add("action", action); routeData.Values.Add("subdomain", subdomain); return routeData; } public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values) { //Implement your formating Url formating here return null; } }

4. Now To get subdomain name in controller:

   public string subdomainName
           {
               get
               {
                   string s = Request.Url.Host;
                   var index = s.IndexOf(".");
                   if (index < 0)
                   {
                       return null;
                   }
                   var sub = s.Split('.')[0];
                   if (sub == "www" || sub == "localhsot")
                   {
                       return null;
                   }
                   return sub;
               }
           }
   

5. My Index method is:

   public string Index() { if (subdomainName == null) { return "No subdomain"; } return subdomainName; }

现在，URL http://localhost:59322/ 正常工作。但是URL http://abc.localhost:59322/ 出现错误：

错误请求 - 无效的主机名

HTTP错误400。请求的主机名无效。

我错在哪里了？为什么子域名不能正常工作？

我3年前问过这个问题，今天又遇到了同样的问题，我也尝试以管理员身份运行VS，有人知道怎么解决吗？ - Irfan Y

虽然有些晚了，但是为了其他人参考，只需在 applicationhost.config 中添加：

<bindings>
     <binding protocol="http" bindingInformation="*:59322:" />
</bindings>
