asp.net-mvc - 从 mvc 5 主页默认路由中删除主页索引

Question

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

// 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"} 
);

Answer 1

您只需忽略 URL:

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: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

然后服务器将返回 404 not find 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 Default 路由的默认值，这将使它们成为必需的。

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 }
        );
    }
}

现在您也无法通过 /Home/ 访问主页(这是使用默认路由访问它的另一个路由)。

当然，最好的选择是使用 canonical tag确保不会有其他可能溜走的路线损害您的 SEO 分数。

<link rel="canonical" href="http://example.com/" />
