How to get RouteData by URL?

I need to get RoutData by given URL string in ASP.NET MVC application.

I've found the way that I need to mock HttpContextBase based on my URL string and then pass it to RouteTable.Routes.GetRouteData() method in Route Parsing (Uri to Route) thread.

How to mock HttpContextBase to retrieve RouteData开发者_C百科 by URL string using RouteTable.Routes.GetRouteData()? Or is there another way to retrieve RouteData by URL?

I used Moq to determine what members of HttpContextBase are used in GetRouteData(). They are:

• Request
  • AppRelativeCurrentExecutionFilePath
  • PathInfo

Request.AppRelativeCurrentExecutionFilePath should return path with ~, what I exactly need, so utility class may be like this one:

public static class RouteUtils
{
    public static RouteData GetRouteDataByUrl(string url)
    {
        return RouteTable.Routes.GetRouteData(new RewritedHttpContextBase(url));
    }

    private class RewritedHttpContextBase : HttpContextBase
    {
        private readonly HttpRequestBase mockHttpRequestBase;

        public RewritedHttpContextBase(string appRelativeUrl)
        {
            this.mockHttpRequestBase = new MockHttpRequestBase(appRelativeUrl);
        }


        public override HttpRequestBase Request
        {
            get
            {
                return mockHttpRequestBase;
            }
        }

        private class MockHttpRequestBase : HttpRequestBase
        {
            private readonly string appRelativeUrl;

            public MockHttpRequestBase(string appRelativeUrl)
            {
                this.appRelativeUrl = appRelativeUrl;
            }

            public override string AppRelativeCurrentExecutionFilePath
            {
                get { return appRelativeUrl; }
            }

            public override string PathInfo
            {
                get { return ""; }
            }
        }
    }
}

Then, you can use it like this (for example on ~/Error/NotFound):

var rd = RouteUtils.GetRouteDataByUrl("~/Error/NotFound")

Which should return an object that looks like this:

RouteData.Values
{
    controller = "Error",
    action = "NotFound"
}

This works for me (.NET 4.5, MVC 5): https://average-joe.info/url-to-route-data/

System.Web.Routing.RouteData routeFromUrl =
    System.Web.Routing.RouteTable.Routes.GetRouteData(
            new HttpContextWrapper(
                new HttpContext(
                    new HttpRequest(null, path, query),
                    new HttpResponse(new System.IO.StringWriter()))));
