如何通过网址获取路由数据?
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;
}
我的问题是,当我访问xyz.mydomain.com
时,它总是被重新路由到xyz.mydomain.com/Business/Display/xyz
。 这阻止我去xyz.mydomain.com/Overview
因为它正在拾取子域并重定向。
我尝试使用 if
语句来确定是否指定了控制器,但似乎没有任何效果。 有什么建议吗?
以防万一其他人需要答案,这是我的解决方案...... substrings.Length >= 3
是针对控制器的,然后是一个操作,因此如果您只需要一个控制器,请更改为 2:
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;
}
