前端Ajax获取当前外网IP地址并通过腾讯接口解析地理位置

目录

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:

使用说明:

韩小韩接口站API大全:韩小韩API接口站 - 免费API数据接口调用服务平台

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

附3、失败的太平洋接口
var whois = {
    root: 'http://whois.pconline.com.cn',
    version: 2.0,
    jsonIp: function () {
        var s = document.getElementsByTagName('head')[0].appendChild(document.createElement("script"));
        /*s.src = this.root + "/jsAlert.jsp?ip=" + ip;*/
        s.type = "application/javascript";
        s.src = this.root + "/ipJson.jsp?callback=callbackRepos";
        console.log(s.src);
    },
    lableIp: function (id, ip) {
        var s = document.getElementsByTagName('head')[0].appendChild(document.createElement("script"));
        s.src = this.root + "/jsLabel.jsp?ip=" + ip + "&id=" + id;
    }
}
function getCurIP() {
    whois.jsonIp();
}
function callbackRepos(res) {
    console.log(res);
    //var data = JSON.stringify(res); //json对象转成字符串
    //console.log(data);
    ipData = res;
}

接口地址:

http://whois.pconline.com.cn

http://whois.pconline.com.cn/ipJson.jsp

只能以如上所示方式调用,在本地可用,一旦部署到外网环境下就是会失败403错误。还会存在跨域问题。所以此法不可用,却浪费了我许多时间。

三、腾讯位置服务-IP位置查询接口

在后台通过腾讯接口将IP地址转换为县区市级别的位置信息,以上的接口只能查询到地级市。

API文档地址:WebService API | 腾讯位置服务

注册腾讯位置服务,创建App,获取app key之后即可在后台调用,

如下所示,返回 省-市-县-县代码

String s = sendGet(ip, KEY);
//        System.out.println("IP地址查询结果s=" + s);
        JSONObject map =new JSONObject(s);
        String message = (String) map.get("message");
        if("Success".equals(message)){
            Map result = (Map) map.get("result");
            Map addressInfo = (Map) result.get("ad_info");
            String nation = (String) addressInfo.get("nation");
            String province = (String) addressInfo.get("province");
            String district = (String) addressInfo.get("district");
            String city = (String) addressInfo.get("city");
            Integer XZQDM = (Integer) addressInfo.get("adcode");
            String address = province + "-" + city + "-" + district + "-"  + XZQDM;
            return address;
        }else{
            System.out.println("message="+message);
            return message;
        }
 //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<String, List<String>> 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;
    }
