ASP.NET获取客户端IP及MAC地址

原创 Linux操作系统 作者:taogchan 时间:2013-07-18 11:09:20 0 删除 编辑

朋友最近问如何获取客户端IP及MAC地址,一直想把这段给整理一下,契机来了;下边分为了C#后台获取的方法和前台Javascript(调用ActiveX)获取的方法,大家如果有好的方法一起讨论撒O(∩_∩)O


C#代码获取:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Runtime.InteropServices;

namespace MyTest
{
    public partial class mac : System.Web.UI.Page
    {
        [DllImport("Iphlpapi.dll")]
        private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);
        [DllImport("Ws2_32.dll")]
        private static extern Int32 inet_addr(string ip);


        protected void Page_Load(object sender, EventArgs e)
        {
            GetMac(); 
        }

        //获取客户端IP
        private string GetClientIP()
        {
            string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
            if (null == result || result == String.Empty)
            {
                result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
            }

            if (null == result || result == String.Empty)
            {
                result = HttpContext.Current.Request.UserHostAddress;
            }
            return result;
        }

 

        //获取MAC地址
        private void GetMac()
        {
            // 在此处放置用户代码以初始化页面
            try
            {
                string userip = Request.UserHostAddress;
                string strClientIP = Request.UserHostAddress.ToString().Trim();
                Int32 ldest = inet_addr(strClientIP); //目的地的ip
                Int32 lhost = inet_addr("");   //本地服务器的ip
                Int64 macinfo = new Int64();
                Int32 len = 6;
                int res = SendARP(ldest, 0, ref macinfo, ref len);
                string mac_src = macinfo.ToString("X");
                if (mac_src == "0")
                {
                    if (userip == "127.0.0.1")
                        Response.Write("正在访问Localhost!");
                    else
                        Response.Write("欢迎来自IP为" + userip + "的朋友!" + "
");
                    return;
                }

                while (mac_src.Length < 12)
                {
                    mac_src = mac_src.Insert(0, "0");
                }

                string mac_dest = "";

                for (int i = 0; i < 11; i++)
                {
                    if (0 == (i % 2))
                    {
                        if (i == 10)
                        {
                            mac_dest = mac_dest.Insert(0, mac_src.Substring(i, 2));
                        }
                        else
                        {
                            mac_dest = "-" + mac_dest.Insert(0, mac_src.Substring(i, 2));
                        }
                    }
                }

                Response.Write("欢迎来自IP为" + userip + "
" + ",MAC地址为" + mac_dest + "的朋友!"

                 + "
");
            }
            catch (Exception err)
            {
                Response.Write(err.Message);
            }


        }
    }
}

Javascript获取:
