无法获取 Web API 控制器方法的 URL

Question

Env: C# Core 3.1 WebApi Project.

In my controller I'm trying to get the current URL but am getting a null value. I've tried a number of things using the Url class:

var x = Url.Link("https://localhost:44397/api/Account/Accounts/", new { a = 1, b = 2 });
var y = Url.RouteUrl("www.xyz.com", new { a = 3, b = 4 });
var url = Url.Link("GetAuthors", authorsResourceParameters);
var r = Url.RouteUrl("This route");
var yd = Url.Action("myAction", "myController", authorsResourceParameters, "https");

The Url class is from Microsoft.AspNetCore.Mvc.Routing.EndpointRoutingUrlHelper. Is this the correct namespace?

What am I missing?

You can use the below code:

var request = HttpContext.Request;

var uri = string.Concat(request.Scheme,"://",
                        request.Host.ToUriComponent(),
                        request.PathBase.ToUriComponent(),
                        request.Path.ToUriComponent(),
                        request.QueryString.ToUriComponent());

good luck.
