获取客户端IP和设备型号

获取ip地址

 @GetMapping(value = "/ip")public  String getIpaddr(HttpServletRequest request) {String ipAddress = request.getHeader("x-forwarded-for");if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getHeader("Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getHeader("WL-Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getRemoteAddr();if (ipAddress.equals("127.0.0.1") || ipAddress.equals("0:0:0:0:0:0:0:1")) {//根据网卡取本机配置的IPInetAddress inet = null;try {inet = InetAddress.getLocalHost();} catch (UnknownHostException e) {e.printStackTrace();}ipAddress = inet.getHostAddress();}}//对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割if (ipAddress != null && ipAddress.length() > 15) { //"***.***.***.***".length() = 15if (ipAddress.indexOf(",") > 0) {ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));}}//  String header = request.getHeader("user-agent"); 获取用户版本号// System.out.println(header);// String remoteAddr = request.getRemoteAddr();//获取ip//System.out.println(remoteAddr);return ipAddress;}

/*** 获取客户端IP** @param request request* @return 客户端IP*/public static String getIpAddr(HttpServletRequest request) {String ip = request.getHeader("x-forwarded-for");if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {if (ip.contains(",")) {ip = ip.split(",")[0];}}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.getHeader("HTTP_CLIENT_IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_X_FORWARDED_FOR");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("X-Real-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}if (StringUtils.isBlank(ip)) {return LOCAL_IPV4;}return ip;}

获取设备信息

 private static String pattern = "^Mozilla/\\d\\.\\d\\s+\\(+.+?\\)";private static String pattern2 = "\\(+.+?\\)";private static Pattern r = Pattern.compile(pattern);private static Pattern r2 = Pattern.compile(pattern2);public static String getDeviceInfo(HttpServletRequest request) {String userAgent = request.getHeader("User-Agent");return getDeviceInfo(userAgent);}private static String getDeviceInfo(String userAgent) {Matcher m = r.matcher(userAgent);String result = null;if (m.find()) {result = m.group(0);}Matcher m2 = r2.matcher(result);if (m2.find()) {result = m2.group(0);}result = result.replace("(", "");result = result.replace(")", "");return filterDeviceInfo(result);}public static String filterDeviceInfo(String result) {if (StringUtils.isBlank(result)) {return null;}result = result.replace(" U;", "");result = result.replace(" zh-cn;", "");return result;}
