我们在开发的过程中可能会遇到获取用户 ip 的要求，这样同时也可以用于大家判断是否为正常用户注册账户…

1. 通过用户请求获取网络 ip

/*** 获取IP地址** 使用Nginx等反向代理软件， 则不能通过request.getRemoteAddr()获取IP地址* 如果使用了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP地址，X-Forwarded-For中第一个非unknown的有效IP字符串，则为真实IP地址*/public static String getIpAddr(HttpServletRequest request) {String ip = null;try {ip = request.getHeader("x-forwarded-for");if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {// 多次反向代理后会有多个ip值，第一个ip才是真实ipif( ip.indexOf(",")!=-1 ){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();}} catch (Exception e) {logger.error("IPUtils ERROR ", e);}return ip;}

2. 通过网络 ip 获取真实的物理地址

这儿我们可以调用淘宝的接口（省事 + 1；

查看淘宝接口的链接地址

/*** description ali地域查询** @param ip ip地址* @return java.lang.String* @version 1.0*/public static String getAddrByIp(String ip) {Map map = new HashMap();map.put("ip", ip);map.put("accessKey", "alibaba-inc");String result = HttpUtil.post("http://ip.taobao.com/outGetIpInfo", map);Map valueMap = JSONObject.parseObject(result, Map.class);// 请求成功，解析响应数据if ("query success".equals(valueMap.get("msg"))) {Map<String, String> dataMap = (Map<String, String>) valueMap.get("data");String city = dataMap.get("city");return city;}return null;}
