Question

我试图阻止用户访问abc.com/Home/Index，而我希望用户只能通过abc.com访问主页。我使用以下代码但不起作用。

＆＃13;

// This code restict user to access abc.com/home/index
// Only allow user to access abc.com/home
routes.MapRoute(
    "OnlyAction",
    "{action}",
    new { controller = "Home", action = "Index" } 
);


// This code does not work, I am expecting this code to allow
// user to access home only at abc.com
routes.MapRoute(
    "Home",
    "",        
    new { controller = "Home", action = "Index"} 
);

您只需忽略该网址：

Default

然后服务器将返回找不到的404而不是页面。

当然，如果您想删除整个应用程序的所有备用路径，则需要删除public class RouteConfig { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); // Ignore the alternate path to the home page routes.IgnoreRoute("Home/Index"); routes.MapRoute( name: "Home", url: "", defaults: new { controller = "Home", action = "Index" } ); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { id = UrlParameter.Optional } ); } }路由的默认值，这将使它们成为必需。

/Home/

现在您无法通过<link rel="canonical" href="http://example.com/" />访问主页（这是使用默认路由访问主页的另一条路径）。

当然，最好的选择是使用canonical tag来确保没有额外的路线可能会损害您的SEO分数。
