How to get route values for any url in asp.net core?

Question

I need to get the route values for an arbitrary URL in ASP.NET MVC Core.

It could be something like this SO question: How to determine if an arbitrary URL matches a defined route, because I haven't found any direct way to do it.

And I haven't been able to do it with that approach either.

It looks like once I have an HttpContext with a Request for the url, it's easy to get the route values, and looking at the source code for aspnet/Hosting in GitHub I got to the point where HttpContextFactory gets created, but that was it, just couldn't go any further!

Does someone know how to do this?

Thanks in advance!

Could you share with us what you tried. It's hard to guess what you're trying to solve. — Jasen, Jul 11 '17 at 23:22
You should probably also check out the aspnet/Routing repository :) — juunas, Jul 12 '17 at 06:07
I'm trying to get the RouteValues out of the referrer url from the Request object, to implement a simple view navigation scheme. It's as if I createed a new Request object with the referrer url and get the RouteValues out of it. — Miguel Veloso, Jul 17 '17 at 17:25

I know this an older post, but this is what I did in order to get RouteData from a RouteCollection running in an ASP.NET MVC Core app based on a URL.

public async Task<ActionResult> GetRouteDataForUrl([FromQuery(Name = "url")] string url)
{
  var uri = new Uri(url);

  var httpContext = new DefaultHttpContext();
  httpContext.Request.Path = uri.PathAndQuery;

  var routeContext = new RouteContext(httpContext);
  var router = RouteData.Routers.First(); //get the top level router

  await router.RouteAsync(routeContext); //router updates routeContext

  return new JsonResult(routeContext.RouteData.Values);
}

The routeContext.RouteData is populated by the root level router.

same error as above - i don't think it is nearly this easy, yet. — Jonesopolis, Aug 30 '20 at 00:41

Ref: Net6 You can install the package and use the namespace using Microsoft.AspNetCore.Routing;

then you can get route values like this

var routeData = _httpContextAccessor.HttpContext.GetRouteData(); ;
var namedRouteValue = _httpContextAccessor.HttpContext.GetRouteValue("route-key");

Thanks, but ViewContext.RouteData has the route values of the current request, what I'm looking for is something like that, but for the referral url. – Miguel Veloso Nov 04 '17 at 21:10
