ASP .Net网络API 2.1获取客户端IP地址

问题描述

您好，我需要得到客户端IP，在网络API请求的一些方法，
我试图用这个code从here但它总是返回服务器的本地IP，
 如何以正确的方式获得？

  HttpContext.Current.Request.UserHostAddress;
 

这是其他问题：

 公共静态类的Htt prequestMessageExtensions
    {
        私人常量字符串的HttpContext =MS_HttpContext;
        私人常量字符串RemoteEndpointMessage =System.ServiceModel.Channels.RemoteEndpointMessageProperty;        公共静态字符串GetClientIpAddress（这Htt的prequestMessage要求）
        {
            如果（request.Properties.ContainsKey（HttpContext的））
            {
                动态CTX = request.Properties [HttpContext的];
                如果（CTX！= NULL）
                {
                    返回ctx.Request.UserHostAddress;
                }
            }            如果（request.Properties.ContainsKey（RemoteEndpointMessage））
            {
                动态remoteEndpoint = request.Properties [RemoteEndpointMessage]
                如果（remoteEndpoint！= NULL）
                {
                    回remoteEndpoint.Address;
                }
            }            返回null;
        }
    }

 使用System.Net.Http;
使用System.ServiceModel.Channels;
使用的System.Web;
使用System.Web.Http;
命名空间Trikks.Controllers.Api
{
    公共类IpController：ApiController
    {
          公共字符串GetIp（）
          {
                返回GetClientIp（）;
          }          私人字符串GetClientIp（HTT prequestMessage要求= NULL）
          {
                请求=请求？请求;                如果（request.Properties.ContainsKey（MS_HttpContext））
                {
                      回报（（HttpContextWrapper）request.Properties [MS_HttpContext]）Request.UserHostAddress。
                }
                否则，如果（request.Properties.ContainsKey（RemoteEndpointMessageProperty.Name））
                {
                     RemoteEndpointMessageProperty道具=（RemoteEndpointMessageProperty）request.Properties [RemoteEndpointMessageProperty.Name]
                     返回prop.Address;
                }
                否则，如果（HttpContext.Current！= NULL）
                {
                    返回HttpContext.Current.Request.UserHostAddress;
                }
                其他
                {
                      返回null;
                }
           }
     }
}
 

这样做的另一种方法是下面

引用：how-to-access-the-client-s-ip-address

对于Web托管版

 字符串clientAddress = HttpContext.Current.Request.UserHostAddress;
 

对于自托管

 对象属性;
        Request.Properties.TryGetValue（typeof运算（RemoteEndpointMessageProperty）.FullName，出属性）;
        RemoteEndpointMessageProperty remoteProperty =财产RemoteEndpointMessageProperty;
 

Hello I need get client IP that request some method in web api,I have tried to use this code from here but it always returns server local IP, how to get in correct way ?

HttpContext.Current.Request.UserHostAddress;

from other questions:

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;
        }
    }

解决方案

Following link might help you. Here's code from the following link.

reference : getting-the-client-ip-via-asp-net-web-api

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;
                }
           }
     }
}

Another way of doing this is below.

reference: how-to-access-the-client-s-ip-address

For web hosted version

string clientAddress = HttpContext.Current.Request.UserHostAddress;

For self hosted

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