java获取用户登录ip、浏览器信息、SessionId

1、获取用户登录ip

//获取用户登录ip;

String loginIp = request.getHeader("X-Forwarded-For");

if (loginIp == null || loginIp.length() == 0 || "http://unknown".equalsIgnoreCase(loginIp)) {

loginIp = request.getHeader("X-Real-IP");

}

if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {

loginIp = request.getHeader("Proxy-Client-IP");

}

if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {

loginIp = request.getHeader("WL-Proxy-Client-IP");

}

if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) {

http://loginIp = request.getHeader("HTTP_CLIENT_IP");

}

if (loginIp == null || loginIp.length() == 0 || "unknowhttp://n".equalsIgnoreCase(loginIp)) {

loginIp = request.getRemoteAddr();

}

2、获取用户所使用的浏览器信息

/**

*获取浏览器信息;

*/

String ua = request.getHeader("User-Agent");

//转成UserAgent对象

UserAgent userAgent = UserAgent.parseUserAgentString(ua);

Browser browser = userAgent.getBrowser();

String browserInfo=browser.toString();//浏览器名

3、获取用户SessionId

request.getSession().getId();

获取用户登录的ip地址（考虑多种请求头的情况）

这段代码网上找的，传一个HttpServletRequest request就行，直接用

public class IpUtil {

/**

* 获取登录用户IP地址

*

* @param request

* @return

*/

public static String getIpAddr(HttpServletRequest request) {

String ip = request.getHeader("x-forwarded-for");

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("Proxy-Client-IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("WL-Proxy-Client-IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getRemoteAddr();

}

if (ip.equals("0:0:0:0:0:0:0:1")) {

ip = "本地";

}

return ip;

}

}
