一、获取访问端IP地址

原计划使用后端HttpServletRequest 获取访问端的IP地址，但在nginx和堡垒机等阻碍下始终只能获得网关的地址，方法如下：

    public String buildLicense_2(@RequestBody Map map, HttpServletRequest request){       //只能获取到网关的ip，获取不到真实IP        String ipAddress = IpUtil.getIpAddr(request);        System.err.println("IP地址："+ipAddress);    }

/**     * 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) {        if (request == null) {            return "unknown";        }        String ip = request.getHeader("x-forwarded-for");        System.out.println("x-forwarded-for IP地址："+ip);        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("Proxy-Client-IP");            System.out.println("Proxy-Client-IP IP地址："+ip);        }        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("X-Forwarded-For");            System.out.println("X-Forwarded-For IP地址："+ip);        }        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("WL-Proxy-Client-IP");            System.out.println("WL-Proxy-Client-IP IP地址："+ip);        }        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("X-Real-IP");            System.out.println("X-Real-IP IP地址："+ip);        }        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getRemoteAddr();        }        try{            System.out.println("getRemoteAddr() IP地址："+request.getRemoteAddr());        }        catch (Exception ex){        }        return "0:0:0:0:0:0:0:1".equals(ip) ? LOCAL_IP : ip;    }

故在前端通过第三方接口，获取当前ip地址后再传到后端

具体如下：

function getIpInfo() {    $.ajax({        url: "https://api.vvhan.com/api/visitor.info",// "https://api.ipify.org?format=json",        type: "GET",         //data: { val1: "1", val2: "2" },        dataType: "json",         success: function (result) {            console.log("IP地址：");            console.log(result);            ipData = result;        },        error: function () {            console.log('获取ip失败');        }    });}

二、可用的IP获取接口

如上所示，使用的是第三方

1、韩小韩IP获取接口：

API地址：https://api.vvhan.com/api/visitor.info

API文档地址：https://api.vvhan.com/fangke.html

返回示例：

 2、ipify API

API地址：https://api.ipify.org?format=json

官网地址：https://www.ipify.org/

 可再各个环境下调用

 //根据在腾讯位置服务上申请的key进行请求操作    private static String sendGet(String ip, String key) {        String result = "";        BufferedReader in = null;        try {            String urlNameString = "https://apis.map.qq.com/ws/location/v1/ip?ip="+ip+"&key="+key;            URL realUrl = new URL(urlNameString);            // 打开和URL之间的连接            URLConnection connection = realUrl.openConnection();            // 设置通用的请求属性            connection.setRequestProperty("accept", "*/*");            connection.setRequestProperty("connection", "Keep-Alive");            connection.setRequestProperty("user-agent",                    "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");            // 建立实际的连接            connection.connect();            // 获取所有响应头字段            Map map = connection.getHeaderFields();            // 遍历所有的响应头字段//            for (Map.Entry entry : map.entrySet()) {//                System.out.println(key + "--->" + entry);//            }            // 定义 BufferedReader输入流来读取URL的响应            in = new BufferedReader(new InputStreamReader(                    connection.getInputStream()));            String line;            while ((line = in.readLine()) != null) {                result += line;            }        } catch (Exception e) {            System.out.println("发送GET请求出现异常！" + e);            e.printStackTrace();        }        // 使用finally块来关闭输入流        finally {            try {                if (in != null) {                    in.close();                }            } catch (Exception e2) {                e2.printStackTrace();            }        }        return result;    }
