Web API 컨트롤러에서 기본 URL을 얻는 방법은 무엇입니까?

Url.Link()특정 경로의 URL을 얻는 데 사용할 수 있다는 것을 알고 있지만 Web API 컨트롤러에서 Web API 기본 URL을 얻으려면 어떻게해야합니까?

---

( )의 VirtualPathRoot속성을 사용할 수 있습니다.HttpRequestContextrequest.GetRequestContext().VirtualPathRoot

---

url " http : // localhost : 85458 / api / ctrl / " 에 대한 요청의 조치 메소드에서

var baseUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority) ;

이것은 당신을 얻을 것입니다 http : // localhost : 85458

---

Url.Content("~/")

나를 위해 일했습니다!

---

이것이 내가 사용하는 것입니다.

Uri baseUri = new Uri(Request.RequestUri.AbsoluteUri.Replace(Request.RequestUri.PathAndQuery, String.Empty));

그런 다음 다른 상대 경로 와 결합 할 때 다음을 사용합니다.

string resourceRelative = "~/images/myImage.jpg";
Uri resourceFullPath = new Uri(baseUri, VirtualPathUtility.ToAbsolute(resourceRelative));

이 서비스를 컨트롤러에 삽입합니다.

 public class LinkFactory : ILinkFactory
 {
    private readonly HttpRequestMessage _requestMessage;
    private readonly string _virtualPathRoot;


    public LinkFactory(HttpRequestMessage requestMessage)
    {
        _requestMessage = requestMessage;
        var configuration = _requestMessage.Properties[HttpPropertyKeys.HttpConfigurationKey] as HttpConfiguration;
        _virtualPathRoot = configuration.VirtualPathRoot;
        if (!_virtualPathRoot.EndsWith("/"))
        {
            _virtualPathRoot += "/";
        }
    }

    public Uri ResolveApplicationUri(Uri relativeUri)
    {

        return new Uri(new Uri(new Uri(_requestMessage.RequestUri.GetLeftPart(UriPartial.Authority)), _virtualPathRoot), relativeUri);
    }

}

Url 도우미 클래스에서 다음 스 니펫을 사용하세요.

Url.Link("DefaultApi", new { controller = "Person", id = person.Id })

This is the official way which does not require any helper or workaround. If you look at this approach is like ASP.NET MVC

---

new Uri(Request.RequestUri, RequestContext.VirtualPathRoot)

---

First you get full URL using HttpContext.Current.Request.Url.ToString(); then replace your method url using Replace("user/login", "").

Full code will be

string host = HttpContext.Current.Request.Url.ToString().Replace("user/login", "")

---

Not sure if this is a Web API 2 addition, but RequestContext has a Url property which is a UrlHelper: HttpRequestContext Properties. It has Link and Content methods. Details here

---

Base on Athadu's answer, I write an extenesion method, then in the Controller Class you can get root url by this.RootUrl();

public static class ControllerHelper
{
    public static string RootUrl(this ApiController controller)
    {
        return controller.Url.Content("~/");
    }
}

---

send a GET to a page and the content replied will be the answer.Base url : http://website/api/

---

In ASP.NET Core ApiController the Request property is only the message. But there is still Context.Request where you can get expected info. Personally I use this extension method:

public static string GetBaseUrl(this HttpRequest request)
{
    // SSL offloading
    var scheme = request.Host.Host.Contains("localhost") ? request.Scheme : "https";
    return $"{scheme}://{request.Host}{request.PathBase}";
}

---

1. Add a reference to System.Web using System.Web;

2. Get the host or any other component of the url you want string host = HttpContext.Current.Request.Url.Host;

---

Al WebApi 2, just calling HttpContext.Current.Request.Path;

---

From HttpRequestMessage

request.Headers.Host
