#學志#[jsp&&php]獲取客戶機mac地址

jsp：

1、首先需要獲取客戶機的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);

結果：
```
127.0.0.1
```
2、根據ip地址獲得客戶機的mac地址
在不同系統下的獲取方式不同；
1）獲得用戶的操作系統：

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

結果：
```
Linux
```
2）根據所在的系統進行mac地址的獲取

     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獲取的方法：

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獲取的方法：

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; 
   } 

關鍵函數：
對結果進行分割獲得mac地址；

/** 
   * 
   * @param ip 目標ip,一般在局域網內 
   * @param sourceString 命令處理的結果字符串 
   * @param macSeparator mac分隔符號 
   * @return mac地址，用上面的分隔符號表示 
   */
   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; //如果有多個IP,只匹配本IP對應的Mac. 
       } 
     }
   
     return result; 
   }
