Asp Net Web API 2.1获取客户端IP地址

Question

您好我需要获取请求web api中的某些方法的客户端IP,我试图从这里使用此代码但它总是返回服务器本地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;
        }
    }

以下链接可能对您有帮助.以下是来自以下链接的代码.

参考: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;
                }
           }
     }
}

另一种方法是在下面.

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

对于Web托管版本

string clientAddress = HttpContext.Current.Request.UserHostAddress;

为自我托管

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

使用Web API 2.2: Request.GetOwinContext().Request.RemoteIpAddress

Answer 3

尝试使用Ip

ip = HttpContext.Current != null ? HttpContext.Current.Request.UserHostAddress : "";

Answer 4

我认为这是最清晰的解决方案，使用扩展方法：

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;
    }
}

所以只需像这样使用它：

var ipAddress = request.GetClientIpAddress();

我们在我们的项目中使用它。

如果您使用OWIN Self-host NuGet包进行Asp.Net 2.1自托管,则可以使用以下代码:

 private string getClientIp(HttpRequestMessage request = null)
    {
        if (request == null)
        {
            return null;
        }

        if (request.Properties.ContainsKey("MS_OwinContext"))
        {
            return ((OwinContext) request.Properties["MS_OwinContext"]).Request.RemoteIpAddress;
        }
        return null;
    }

回复这个已有4年历史的帖子，因为对我来说，这似乎过于复杂，至少如果您在IIS上托管，并且此帖子在DuckDuckGo（可能还有NSAoogle）上针对“ Web api控制器获取IP地址”的建议很高。

这是我解决的方法：

using System;
using System.Net;
using System.Web;
using System.Web.Http;
...
[HttpPost]
[Route("ContactForm")]
public IHttpActionResult PostContactForm([FromBody] ContactForm contactForm)
    {
        var hostname = HttpContext.Current.Request.UserHostAddress;
        IPAddress ipAddress = IPAddress.Parse(hostname);
        IPHostEntry ipHostEntry = Dns.GetHostEntry(ipAddress);
        ...

与OP不同，这为我提供了客户端IP和客户端主机名，而不是服务器。也许从那以后他们已经修复了该错误？

最好将它投射到HttpContextBase这种方式,这样你就可以更容易地模拟和测试它

public string GetUserIp(HttpRequestMessage request)
{
    if (request.Properties.ContainsKey("MS_HttpContext"))
    {
        var ctx = request.Properties["MS_HttpContext"] as HttpContextBase;
        if (ctx != null)
        {
            return ctx.Request.UserHostAddress;
        }
    }

    return null;
}
