String agent = request.getHeader(“user-agent”);  
System.out.println(agent);  
StringTokenizer st = new StringTokenizer(agent,”;”);  
st.nextToken();  
String userbrowser = st.nextToken();  
System.out.println(userbrowser);  
String useros = st.nextToken();

//获得客户端的ip地址 
    String ip = req.getRemoteAddr();
    //根据ip获取mac地址
    String mac;
    try {
        mac = HostUtils.getLocalMac(ip);
    } catch (Exception e) {
        throw new BusinessException("获取mac地址异常" + e.getMessage());
    
    }

System.out.println(useros);  
System.out.println(System.getProperty(“os.name”)); //win2003竟然是win xp？  
System.out.println(System.getProperty(“os.version”));  
System.out.println(System.getProperty(“os.arch”));  
System.out.println(request.getHeader(“user-agent”)); //返回客户端浏览器的版本号、类型  
System.out.println(request.getMethod()); //：获得客户端向服务器端传送数据的方法有get、post、put等类型  
System.out.println(request.getRequestURI()); //：获得发出请求字符串的客户端地址  
System.out.println(request.getServletPath()); //：获得客户端所请求的脚本文件的文件路径  
System.out.println(request.getServerName()); //：获得服务器的名字  
System.out.println(request.getServerPort()); //：获得服务器的端口号  
System.out.println(request.getRemoteAddr()); //：获得客户端的ip地址  
System.out.println(request.getRemoteHost()); //：获得客户端电脑的名字，若失败，则返回客户端电脑的ip地址  
System.out.println(request.getProtocol()); //：  
System.out.println(request.getHeaderNames()); //：返回所有request header的名字，结果集是一个enumeration（枚举）类的实例  
System.out.println(“Protocol: ” + request.getProtocol());  
System.out.println(“Scheme: ” + request.getScheme());  
System.out.println(“Server Name: ” + request.getServerName() );  
System.out.println(“Server Port: ” + request.getServerPort());  
System.out.println(“Protocol: ” + request.getProtocol());  
System.out.println(“Server Info: ” + getServletConfig().getServletContext().getServerInfo());  
System.out.println(“Remote Addr: ” + request.getRemoteAddr());  
System.out.println(“Remote Host: ” + request.getRemoteHost());  
System.out.println(“Character Encoding: ” + request.getCharacterEncoding());  
System.out.println(“Content Length: ” + request.getContentLength());  
System.out.println(“Content Type: “+ request.getContentType());  
System.out.println(“Auth Type: ” + request.getAuthType());  
System.out.println(“HTTP Method: ” + request.getMethod());  
System.out.println(“Path Info: ” + request.getPathInfo());  
System.out.println(“Path Trans: ” + request.getPathTranslated());  
System.out.println(“Query String: ” + request.getQueryString());  
System.out.println(“Remote User: ” + request.getRemoteUser());  
System.out.println(“Session Id: ” + request.getRequestedSessionId());  
System.out.println(“Request URI: ” + request.getRequestURI());  
System.out.println(“Servlet Path: ” + request.getServletPath());  
System.out.println(“Accept: ” + request.getHeader(“Accept”));  
System.out.println(“Host: ” + request.getHeader(“Host”));  
System.out.println(“Referer : ” + request.getHeader(“Referer”));  
System.out.println(“Accept-Language : ” + request.getHeader(“Accept-Language”));  
System.out.println(“Accept-Encoding : ” + request.getHeader(“Accept-Encoding”));  
System.out.println(“User-Agent : ” + request.getHeader(“User-Agent”));  
System.out.println(“Connection : ” + request.getHeader(“Connection”));  
System.out.println(“Cookie : ” + request.getHeader(“Cookie”));

获得user-agent的值

在 ASP.NET 中使用 Request.Header\[“User-Agent”\] 得到浏览器的 User Agent，也可以使用 Request.UserAgent 来获取；  
Java 中使用 request.getHeader(”User-Agent”) 来获得；  
PHP 中相应使用：$\_SERVER\[HTTP\_USER\_AGENT\]；

JS中则使用navigator.userAgent来获得（客户端经常使用它来做浏览器兼容）。
