Java如是获得客户端Mac地址? 而不是本机的Mac地址

Question

我是用Liunx来开发Java的,现在要开发一个获取客户端Mac的需求,我网上找了一些代码都是能得到本机的MAC地址,而不是客户端的MAC地址,哪位大哥,帮帮忙,看看改改程序,能不能变成客户端执行服务端就能获得客户端MAC地址,谢谢了~package kaga.it.Tools;    import java.io.BufferedReader;

Answer 1

http://rodneytt.iteye.com/blog/544676好像大部分都是通过ip来获取客户端的mac地址的、ip可以通过request获取到

Answer 2

在客户端开发一段代码，可以获取并返回Mac地址，然后服务器发消息让客户端提交过来就是了。
能够从服务器端直接的到客户端Mac地址的方法虽然有，但是基本上只限于相同网段内。

Answer 3

<script language="JScript" event=OnObjectReady(objObject,objAsyncContext) for="someaddr">
            if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
            {
            if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
             MACAddr = objObject.MACAddress;
            if(objObject.IPEnabled && objObject.IPAddress(0) != null && objObject.IPAddress(0) != "undefined")
             IPAddr = objObject.IPAddress(0);
            if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
             sDNSName = objObject.DNSHostName;
            }
        </script>        <script type="text/javascript" event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for="someaddr">
         var hidMacString=unescape(MACAddr);
         var hidMac=hidMacString.replace(/:/g,"-");
            document.getElementById('hidMac').value=hidMac ;
            </script>
里面的hidMac就是mac地址可能需要设置下浏览器的安全级别

Answer 4

是的,WEB开发,目前还没有找到有效的方法

Answer 5

Web开发的话，就需要借助ActiveX来处理了，比如Applet也算是ActiveX。总的来说就是客户端（浏览器）获取到本机Mac，然后提交给服务器端。

Answer 6

有没有具体的实现代码呢,,我是在liunx环境下开发的,如是有现成的代码就好了

Answer 7

web开发的话，我刚贴的那一段就行；

Answer 8

<script language="JScript" event=OnObjectReady(objObject,objAsyncContext) for="someaddr">
            if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
            {
                if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
                    MACAddr = objObject.MACAddress;
                if(objObject.IPEnabled && objObject.IPAddress(0) != null && objObject.IPAddress(0) != "undefined")
                    IPAddr = objObject.IPAddress(0);
                if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
                    sDNSName = objObject.DNSHostName;
            }
        </script>        <script type="text/javascript" event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for="someaddr">
            var hidMacString=unescape(MACAddr);
            var hidMac=hidMacString.replace(/:/g,"-");
            document.getElementById('hidMac').value=hidMac ;
            </script>弱弱的问一下,我是新手,js不是很熟悉,html代码如何得到hidMac的值呀,    <form action="UserLogin.action" method="post">
        <div align="center">得到MAC地址
         
          <br>MAC地址是:
          <input type="text" name="hidMac" value="hidMac"/>
          <br>
       
        <input name="submit" type="submit" value="提交">
        <input name="reset" type="reset" value="重置">
        </div>
      </form>这样子行吗,不行的话,帮我改一下代码吧,谢谢了!!!!!

Answer 9

 <form action="UserLogin.action" method="post">
        <div align="center">得到MAC地址
         
          <br>MAC地址是:
          <input type="text" id="hidMac" name="hidMac" />
          <br>
       
        <input name="submit" type="submit" value="提交">
        <input name="reset" type="reset" value="重置">
        </div>
      </form>这样子还是获得不到.....哎...

Answer 10

改成隐藏域  在js 中通过变量 给它赋值  然后 表单提交 也可以拼url 把值传过去

Answer 11

能不能帮我写几行表单读JS的hidMac变量值,谢谢了!!-

Answer 12

<script>
function gosubmit(){
document.getElementById("hidMac").value=hidMac;
document.macForm.action="UserLogin";
document.macForm.submit();
}
</script>
<form name="macForm" method="post">
<input type="hidden" name="hidMac" id="hidMac" />
<input type="button" value="提交" onclick="javascript:gosubmit();" />
</form>
大概 或许 是这样 

Answer 13

String hidMac = req.getParameter("hidMac");//客户端网卡地址

                 System.out.println("客户端网卡地址:"+hidMac);
结果输出是:客户端网卡地址:[object HTMLInputElement]还是没有用.....

Answer 14

ie下面拿js是可以获取到mac地址的。js是在客户端执行的。
火狐下面不可以。jsp、java代码取到的都是服务器的mac。

Answer 15

已经解决,yugao2918的方法可以用,谢谢了 但是FIRFOX死活都获取不到IP
