我想创建动态 url，路由到具有 Id 值的控制器操作。我使用包罗万象的参数创建了以下路线

routes.MapRoute(
            "RouteName",                                                 
            "{id}/{*Url}",
            new { controller = "Controller", action = "Action", id = "" }
        );

这可以按预期工作，并允许我使用以下网址：

“ http://website.com/1/fake/url/path ”（1 是传递给操作方法的 id）

有谁知道在不创建我自己的 http 模块的情况下以这种方式实现它的方法？：

“ http://website.com/fake/url/path/1 ”

谢谢 - 马克

无论如何，这对我来说真的很难。

给定以下路线：

routes.MapRoute("Default", "{*token}", 
    new { controller = "Home", action = "Index", token = 0 });

您的控制器和支持类将是这样的：

[HandleError]
public class HomeController : Controller
{
    public ActionResult Index([ModelBinder(typeof(IndexReqquestBinder))] IndexRequest request)
    {
        ViewData["Title"] = "Home Page";
        ViewData["Message"] = String.Format("We're looking at ID: {0}", request.ID);

        return View();
    }
}

public class IndexRequest
{
    public Int32 ID { get; set; }
    public IndexRequest(Int32 id)
    {
        this.ID = id;
    }
}

public class IndexReqquestBinder : IModelBinder
{
    public ModelBinderResult BindModel(ModelBindingContext bindingContext)
    {
        if ( null != bindingContext.RouteData.Values["token"] ) {
            foreach ( String v in bindingContext.RouteData.Values["token"].ToString().Split('/') ) {
                Int32 id = 0;
                if ( Int32.TryParse(v, out id) ) {
                    return new ModelBinderResult(new IndexRequest(id));
                }
            }

        }
        return new ModelBinderResult(new IndexRequest(0));
    }
}

路由重定向基于路由表中的路由条目。它必须以系统的方式进行。例如，如果您在 {controller}/{action}/{id}（mvc 的默认值）之后将路由作为“customurl/id”，当您在 url 框中输入“customurl”时，它将把它作为默认路由并且没有页面会发生发现异常。因此，如果您想使用自定义路由，请先删除默认路由。我喜欢这样做。 

RouteCollection routes = RouteTable.Routes;
                    if (routes["rname"] != null)
                    {
                        RouteTable.Routes.Remove(routes["rname"]);
                    }
                         routes.Remove(routes["Default"]);                           
                        routes.MapRoute(
                            name: "newname",
                            url: url + "/{customId}",
                            defaults: new { controller = "Search", action = "Index", customId = UrlParameter.Optional }
                            );

                        //default route value
                        routes.MapRoute(
                            name: "Default",
                            url: "{controller}/{action}/{id}",
                            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
                            );

我建议覆盖 DefaultControllerFactory

>             catch (Exception exception)
>             {
>                 // collect route data

而不仅仅是在 global.asax.cs 文件中将其注册为默认控制器工厂

protected void Application_Start()
        {
            ControllerBuilder.Current.SetControllerFactory(new MyNameSpace.CustomControllerFactory ());
            RegisterRoutes(RouteTable.Routes); // this already exists by default
        }
