Question

我有这样的托管和域名：

www.EXAMPLE.com

我创建了几个这样的子域名：

www.PAGE1.EXAMPLE.com
www.PAGE2.EXAMPLE.com
www.PAGE3.EXAMPLE.com
... etc...

所有这些子域都指向同一个ASP.NET MVC 5应用程序。

我想制作根据子域加载数据的系统。例如：

我有文章对象，可以是自动评论或游戏评论或书评等......

我想www.auto.example.com加载文章类型为Auto的数据，到www.book.example.com我想加载类型为Book等的数据。

会有很多类型的网页。

这样做的最佳做法是什么？

顶级域名www.example.com应该显示其他内容。这将是其他人的主页。

您可以通过编写自定义路线来完成此操作。这是如何（改编自Is it possible to make an ASP.NET MVC route based on a subdomain?）

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); //Goes to the relevant Controller  class
        routeData.Values.Add("action", action); //Goes to the relevant action method on the specified Controller
        routeData.Values.Add("subdomain", subdomain); //pass subdomain as argument to action method
        return routeData;
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        //Implement your formating Url formating here
        return null;
    }
}

像这样添加到Global.asax.cs中的路由表：

routes.Add(new SubdomainRoute());

你的控制器方法：

public ActionResult Index(string subdomain)
{
    //Query your database for the relevant articles based on subdomain
    var viewmodel = MyRepository.GetArticles(subdomain);
    Return View(viewmodel);
}

Answer 2

这是我想用ASP.NET MVC做很长时间的事情，但是......这不是ASP.NET MVC负责的问题。这是服务器问题（IIS）。您需要做的是允许IIS服务器上的通配符子域，并将它们指向一个应用程序。

然后你可以用 HttpContext ：

做这样的事情

HttpContext.Current.Request.Url.Host // user1.yourwebsite.com

然后你只需解析它并将其推送到你认为合适的ASP.NET MVC应用程序中：

将其推入会话
更新当前路线数据并按
等...

选择权取决于你。

注意：这方面的缺点是，这会使本地开发变得越来越困难，因此您可能想要在应用程序中模拟一种伪造子域名的方法。

我尝试Paul Taylor上面的答案非常好，但这对我来说并不完全有效。我使用Route类的实现。

将您的自定义域添加到C:/Windows/System32/drivers/etc/hosts文件
