如何在所有浏览器中获取客户端mac地址 [英] how to get client mac address in all browser

问题描述

大家好，

如何获取客户端mac地址。在这里我使用下面的脚本，但它的工作原理仅适用于所有浏览器。这个代码我托管在服务器中但是也没有检索任何值，即使也是。





脚本： -

 function callme（）{
  var  macAddress =  ; 
  var  ipAddress =  ; 
  var  computerName =  ; 
  var  wmi = GetObject（  winmgmts： {impersonationLevel =冒充}）; 
e =  new 枚举器（wmi.ExecQuery（  SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True））; 
  for （;！e.atEnd（）; e.moveNext（））{
  var  s = e.item（）; 
 macAddress = s.MACAddress; 
 ipAddress = s.IPAddress（ 0 ）; 
 computerName = s.DNSHostName; 
 alert（macAddress）; 
 document.getElementById（'  ctl00_cplhControlPanel_macAddress'）。 value  = macAddress; 
} 
} 

这里函数调用onclientevent。请在所有浏览器中帮助我

解决方案

您不能 - MAC地址不会超出路由器，因此您必须在客户端上运行代码。我知道的唯一方法是IE特定的。



说实话，它可能无法帮助你：MAC地址不是唯一的（它们只需要在LAN网段中是唯一的）并且它们很容易被欺骗。因此，如果你打算使用MAC进行身份识别/授权，我建议你忘掉它并安装一个cookie。

我在这里使用了它



（使用System.Runtime.InteropServices;）

[DllImport（Iphlpapi.dll）]

private static extern int SendARP（Int32 dest，Int32主机，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）

{

try

{

string userip = Request.UserHostAddress;

string strClientIP = Request.UserHostAddress.ToString（）。Trim（）;

Int32 ldest = inet_addr（strClientIP）;

Int32 lhost = inet_addr（）;

Int64 macinfo = new Int64（）;

Int32 len = 6;

int res = SendARP（ldest，0，ref macinfo，ref len）;

string mac_src = macinfo.ToString（X）;

i f（mac_src ==0）

{

if（userip ==127.0.0.1）

Response.Write（访问过Localhost！）;

else

Response.Write（IP from+ userip ++
）;

返回;

}



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（welcome+ userip +
+，mac地址是+ mac_dest +。



+
）;

}

catch（例外错误）

{

Response.Write（err.Message）;

}

hi to all,
How to get client mac address. here i using this below script but its works only in ie not in all browser. and this code i hosted in server but not retrieve any value even in ie also.


SCRIPTS:-

function callme() {
           var macAddress = "";
           var ipAddress = "";
           var computerName = "";
           var wmi = GetObject("winmgmts:{impersonationLevel=impersonate}");
           e = new Enumerator(wmi.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True"));
           for (; !e.atEnd() ; e.moveNext()) {
               var s = e.item();
               macAddress = s.MACAddress;
               ipAddress = s.IPAddress(0);
               computerName = s.DNSHostName;
               alert(macAddress);
               document.getElementById('ctl00_cplhControlPanel_macAddress').value = macAddress;
           }
       }

here this function call in onclientevent. kindly help me in all browser

解决方案

You can't - MAC addresses do not travel beyond the router, so you have to run code on the client. And the only ways to do that I know of are IE specific.

And to be honest, it probably won't help you: MAC addresses aren't unique (they only have to be unique within a LAN segment) and they are very easy to spoof. So if you are planning on using MAC for identification / authorization, I would recommend you forget it and install a cookie instead.

i got it here i used

(using System.Runtime.InteropServices;)
[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)
{
try
{
string userip = Request.UserHostAddress;
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP);
Int32 lhost = inet_addr("");
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("visited Localhost!");
else
Response.Write("the IP from" + userip + "" + "
");
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("welcome" + userip + "
" + ",the mac address is" + mac_dest + "."

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