#学志#[jsp&&php]获取客户机mac地址

jsp：

1、首先需要获取客户机的ip地址

String sip = request.getHeader("x-forwarded-for"); if (sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) { sip = request.getHeader("Proxy-Client-IP"); } if (sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) { sip = request.getHeader("WL-Proxy-Client-IP"); } if (sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) { sip = request.getRemoteAddr(); } System.out.println(sip);

结果：
```
127.0.0.1
```
2、根据ip地址获得客户机的mac地址
在不同系统下的获取方式不同；
1）获得用户的操作系统：

String os = System.getProperty("os.name");  System.out.println(os);

结果：
```
Linux
```
2）根据所在的系统进行mac地址的获取

     String macAddress = null;     if(os.equals("Windows"))     macAddress = getMacInWindows(ip).trim();     else if(os.equals("Linux"))     macAddress = getMacInLinux(ip).trim();     return macAddress;

其中在windows获取的方法：

public static String getMacInWindows(final String ip){      String result = "";      String[] cmd = {          "cmd",          "/c",          "ping " + ip          };      String[] another = {          "cmd",          "/c",          "arp -a"         };         String cmdResult = callCmd(cmd,another);      result = filterMacAddress(ip,cmdResult,"-");         return result;    } 

在Linux获取的方法：

public static String getMacInLinux(final String ip){      String result = "";      String[] cmd = {          "/bin/sh",          "-c",          "ping " + ip + " -c 2 && arp -a"         };      String cmdResult = callCmd(cmd);      result = filterMacAddress(ip,cmdResult,":");         return result;    } 

关键函数：
对结果进行分割获得mac地址；

/**    *    * @param ip 目标ip,一般在局域网内    * @param sourceString 命令处理的结果字符串    * @param macSeparator mac分隔符号    * @return mac地址，用上面的分隔符号表示    */   public static String filterMacAddress(final String ip, final String sourceString,final String macSeparator) {      String result = "";      String regExp = "((([0-9,A-F,a-f]{1,2}" + macSeparator + "){1,5})[0-9,A-F,a-f]{1,2})";      Pattern pattern = Pattern.compile(regExp);      Matcher matcher = pattern.matcher(sourceString);      while(matcher.find()){        result = matcher.group(1);        if(sourceString.indexOf(ip) <= sourceString.lastIndexOf(matcher.group(1))) {          break; //如果有多个IP,只匹配本IP对应的Mac.        }      }        return result;    }

完整版代码：
java获取类：

package test;import java.io.BufferedReader;import java.io.InputStreamReader;import java.util.regex.Matcher;import java.util.regex.Pattern;  /*** 获取MAC地址* @author* 2011-12*/public class GetMacAddress {   public static String callCmd(String[] cmd) {      String result = "";      String line = "";      try {        Process proc = Runtime.getRuntime().exec(cmd);        InputStreamReader is = new InputStreamReader(proc.getInputStream());        BufferedReader br = new BufferedReader (is);        while ((line = br.readLine ()) != null) {        result += line;        }      }      catch(Exception e) {        e.printStackTrace();      }      return result;    }       /**    *    * @param cmd 第一个命令    * @param another 第二个命令    * @return  第二个命令的执行结果    */   public static String callCmd(String[] cmd,String[] another) {      String result = "";      String line = "";      try {        Runtime rt = Runtime.getRuntime();        Process proc = rt.exec(cmd);        proc.waitFor(); //已经执行完第一个命令，准备执行第二个命令        proc = rt.exec(another);        InputStreamReader is = new InputStreamReader(proc.getInputStream());        BufferedReader br = new BufferedReader (is);        while ((line = br.readLine ()) != null) {          result += line;        }      }      catch(Exception e) {        e.printStackTrace();      }      return result;    }               /**    *    * @param ip 目标ip,一般在局域网内    * @param sourceString 命令处理的结果字符串    * @param macSeparator mac分隔符号    * @return mac地址，用上面的分隔符号表示    */   public static String filterMacAddress(final String ip, final String sourceString,final String macSeparator) {      String result = "";      String regExp = "((([0-9,A-F,a-f]{1,2}" + macSeparator + "){1,5})[0-9,A-F,a-f]{1,2})";      Pattern pattern = Pattern.compile(regExp);      Matcher matcher = pattern.matcher(sourceString);      while(matcher.find()){        result = matcher.group(1);        if(sourceString.indexOf(ip) <= sourceString.lastIndexOf(matcher.group(1))) {          break; //如果有多个IP,只匹配本IP对应的Mac.        }      }        return result;    }               /**    *    * @param ip 目标ip    * @return  Mac Address    *    */   public static String getMacInWindows(final String ip){      String result = "";      String[] cmd = {          "cmd",          "/c",          "ping " + ip          };      String[] another = {          "cmd",          "/c",          "arp -a"         };         String cmdResult = callCmd(cmd,another);      result = filterMacAddress(ip,cmdResult,"-");         return result;    }     /**    * @param ip 目标ip    * @return  Mac Address    *    */   public static String getMacInLinux(final String ip){      String result = "";      String[] cmd = {          "/bin/sh",          "-c",          "ping " + ip + " -c 2 && arp -a"         };      String cmdResult = callCmd(cmd);      result = filterMacAddress(ip,cmdResult,":");         return result;    }        /**   * 获取MAC地址    * @return 返回MAC地址   */   public static String getMacAddress(String ip){ //判断操作系统 String os = System.getProperty("os.name");  // System.out.println(os + " can't gunzip");           String macAddress = null;     if(os.equals("Windows"))     macAddress = getMacInWindows(ip).trim();     else if(os.equals("Linux"))     macAddress = getMacInLinux(ip).trim();     return macAddress;   }    //做个测试   public static void main(String[] args) {           System.out.println("220.181.111.148's mac is "+getMacAddress("220.181.111.148"));     System.out.println("127.0.0.1's mac is "+getMacAddress("127.0.0.1"));   }   }

测试结果：
```
220.181.111.148's mac is 
127.0.0.1's mac is 74:25:8a:3c:6d:2f
```
