.net core如何进行url解析，.net版本可以如下进行解析，但是.net core没有这种操作

Question

            HttpRequest hr = new HttpRequest("", url, "");//这里的url就是要解析的url
            TextWriter stringWriter = new StringWriter();
            HttpResponse hrs = new HttpResponse(stringWriter);
            HttpContext hc = new HttpContext(hr, hrs);
            HttpContextWrapper hcw = new HttpContextWrapper(hc);            bool blResult = false;            foreach (Route r in System.Web.Routing.RouteTable.Routes)
            {
                RouteData rt = r.GetRouteData(hcw);
                if (rt != null)
                {
                    controller = rt.Values["Controller"].ToString();//解析出来的Controller
                    action = rt.Values["Action"].ToString();//解析出来的Action
                    blResult = true;
                    break;
                }
            }

Answer 1

类工厂   IControllerFactory  factory = ControllerBuilder.GetControllerFactory();
 controller = factory.CreateController(RequestContext, controllerName);
