ASP Net Web API 2.1获取客户端IP地址

您好，我需要在Web
api中获取请求某种方法的客户端IP，我尝试从此处使用此代码，但它始终返回服务器本地IP，如何以正确的方式获取？

HttpContext.Current.Request.UserHostAddress;

来自其他问题：

public static class HttpRequestMessageExtensions
    {
        private const string HttpContext = "MS_HttpContext";
        private const string RemoteEndpointMessage = "System.ServiceModel.Channels.RemoteEndpointMessageProperty";

        public static string GetClientIpAddress(this HttpRequestMessage request)
        {
            if (request.Properties.ContainsKey(HttpContext))
            {
                dynamic ctx = request.Properties[HttpContext];
                if (ctx != null)
                {
                    return ctx.Request.UserHostAddress;
                }
            }

            if (request.Properties.ContainsKey(RemoteEndpointMessage))
            {
                dynamic remoteEndpoint = request.Properties[RemoteEndpointMessage];
                if (remoteEndpoint != null)
                {
                    return remoteEndpoint.Address;
                }
            }

            return null;
        }
    }

以下链接可能会对您有所帮助。这是来自以下链接的代码。

参考：通过asp-net-web-api获取客户端IP

using System.Net.Http;
using System.ServiceModel.Channels;
using System.Web;
using System.Web.Http;


namespace Trikks.Controllers.Api
{
    public class IpController : ApiController
    {
          public string GetIp()
          {
                return GetClientIp();
          }

          private string GetClientIp(HttpRequestMessage request = null)
          {
                request = request ?? Request;

                if (request.Properties.ContainsKey("MS_HttpContext"))
                {
                      return   ((HttpContextWrapper)request.Properties["MS_HttpContext"]).Request.UserHostAddress;
                }
                else if (request.Properties.ContainsKey(RemoteEndpointMessageProperty.Name))
                {
                     RemoteEndpointMessageProperty prop = (RemoteEndpointMessageProperty)request.Properties[RemoteEndpointMessageProperty.Name];
                     return prop.Address;
                }
                else if (HttpContext.Current != null)
                {
                    return HttpContext.Current.Request.UserHostAddress;
                }
                else
                {
                      return null;
                }
           }
     }
}

下面是另一种方法。

参考：如何访问客户端的IP地址

对于网络托管版本

string clientAddress = HttpContext.Current.Request.UserHostAddress;

对于自托管

object property;
        Request.Properties.TryGetValue(typeof(RemoteEndpointMessageProperty).FullName, out property);
        RemoteEndpointMessageProperty remoteProperty = property as RemoteEndpointMessageProperty;
