如何获取客户端MAC地址

方法一:
调用Windows的DOS命令,从输出结果中读取MAC地址:
public static String getMACAddress() {

String address = "";
String os = System.getProperty("os.name");
if ( os != null && os.startsWith("Windows")) {
try {
String command = "cmd.exe /c ipconfig /all";
Process p = Runtime.getRuntime().exec(command);
BufferedReader br =
new BufferedReader(
new InputStreamReader(p.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
if (line.indexOf("Physical Address") > 0) {
int index = line.indexOf(":");
index += 2;
address = line.substring(index);
break;
}
}
br.close();
return address.trim();
}
catch (IOException e) { }
}
return address;
}

We can replace the "ipconfig" to "ping x.x.x.x" and "arp -a"...We can get the mac list...haha!!

缺点:只能取得服务器端MAC地址.如果要取得客户端的MAC地址,需用Applet.只针对MS-WIN系统.
 
方法二:
可以用JS或vbscript来调用WMI接口来获取Client端的MAC地址.
