这篇文章主要讲解了“java怎么通过IP解析地理位置”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“java怎么通过IP解析地理位置”吧!
在项目开发中,需要在登录日志或者操作日志中记录客户端ip所在的地理位置。
目前根据ip定位地理位置的第三方api有好几个,淘宝、新浪、百度等,这三种其实也有些缺点的:
淘宝,开始几次可以成功根据ip获取对应地理位置,但后面就莫名其妙开始不行,直接通过浏览器获取又可以;
新浪,之前一直可以,但最近不知道为什么不行了,访问直接报错(可能api修改了或者取消了吧);
百度,需要申请百度地图开发者平台的开发者账号,请求时接口中需要加上百度提供的秘钥等信息,好像不能定位国外的ip,但是针对国内的可以使用。
java IP地址工具类,java IP地址获取,java获取客户端IP地址

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.UnsupportedEncodingException; import java.net.MalformedURLException; import java.net.URL; import java.net.URLConnection; import org.json.JSONException; import org.json.JSONObject; public class Ip2LocationViaBaidu { /** * 根据IP查询地理位置 * @param ip * 查询的地址 * @return status * 0:正常 * 1:API查询失败 * 2:API返回数据不完整 * @throws IOException * @throws JSONException */ public static Object[] getLocation(String ip) throws IOException, JSONException { String lng = null;// 经度 String lat = null;// 纬度 String province=null;//省 String city = null;// 城市名 String status = "0";// 成功 String ipString = null; String jsonData = ""; // 请求服务器返回的json字符串数据 try { ipString = java.net.URLEncoder.encode(ip, "UTF-8"); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } /* * 请求URL http://api.map.baidu.com/location/ip?ak=您的AK&ip=您的IP&coor=bd09ll //HTTP协议 https://api.map.baidu.com/location/ip?ak=您的AK&ip=您的IP&coor=bd09ll //HTTPS协议 */ String key = "*************";// 百度密钥(AK),此处换成自己的AK String url = String.format("https://api.map.baidu.com/location/ip?ak=%s&ip=%s&coor=bd09ll", key, ipString);// 百度普通IP定位API URL myURL = null; URLConnection httpsConn = null; try { myURL = new URL(url); } catch (MalformedURLException e) { e.printStackTrace(); } InputStreamReader insr = null; BufferedReader br = null; try { httpsConn = (URLConnection) myURL.openConnection();// 不使用代理 if (httpsConn != null) { insr = new InputStreamReader(httpsConn.getInputStream(), "UTF-8"); br = new BufferedReader(insr); String data = null; int count = 1; while ((data = br.readLine()) != null) { jsonData += data; } JSONObject jsonObj = new JSONObject(jsonData); if ("0".equals(jsonObj.getString("status"))) { province = jsonObj.getJSONObject("content").getJSONObject("address_detail").getString("province"); city = jsonObj.getJSONObject("content").getJSONObject("address_detail").getString("city"); lng = jsonObj.getJSONObject("content").getJSONObject("point").getString("x"); lat = jsonObj.getJSONObject("content").getJSONObject("point").getString("y"); if (city.isEmpty() || lng.isEmpty() || lat.isEmpty()) { status = "2";// API返回数据不完整 } } else { status = "1";// API查询失败 } } } catch (IOException e) { e.printStackTrace(); } finally { if (insr != null) { insr.close(); } if (br != null) { br.close(); } } return new Object[] { status, province, city, lng, lat }; } }
把上边的百度密钥换成你自己的,下边是API返回的json数据格式。
{ address: "CN|北京|北京|None|CHINANET|1|None", #地址 content: #详细内容 { address: "北京市", #简要地址 address_detail: #详细地址信息 { city: "北京市", #城市 city_code: 131, #百度城市代码 district: "", #区县 province: "北京市", #省份 street: "", #街道 street_number: "" #门址 }, point: #当前城市中心点 { x: "116.39564504", y: "39.92998578" } }, status: 0 #返回状态码 }
1、添加依赖
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.3</version> </dependency>
2、工具类代码
package com.shucha.deveiface.biz.test; /** * @author tqf * @Description 根据ip获取归属地 * @Version 1.0 * @since 2022-05-27 10:11 */ import cn.hutool.core.util.StrUtil; import cn.hutool.http.HttpUtil; import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; import com.itextpdf.text.log.Logger; import com.itextpdf.text.log.LoggerFactory; import lombok.Data; import org.apache.commons.lang3.StringUtils; import javax.servlet.http.HttpServletRequest; public class iptes { private static Logger logger = LoggerFactory.getLogger(iptes.class); /** * 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 (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("Proxy-Client-IP"); } if (StringUtils.isEmpty(ip) || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("WL-Proxy-Client-IP"); } if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_CLIENT_IP"); } if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_X_FORWARDED_FOR"); } if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } } catch (Exception e) { logger.error("IPUtils ERROR ", e); } //使用代理,则获取第一个IP地址 if(StringUtils.isEmpty(ip) ) { if(ip.indexOf(",") > 0) { ip = ip.substring(0, ip.indexOf(",")); } } return ip; } /** * 根据ip获取归属地 * @param ip * @return */ public static IpAddress getAddress(String ip) { String url = "http://ip.ws.126.net/ipquery?ip=" + ip; String str = HttpUtil.get(url); if(!StrUtil.hasBlank(str)){ String substring = str.substring(str.indexOf("{"), str.indexOf("}")+1); JSONObject jsonObject = JSON.parseObject(substring); String province = jsonObject.getString("province"); String city = jsonObject.getString("city"); IpAddress ipAddress = new IpAddress(); ipAddress.setProvince(province); ipAddress.setCity(city); System.out.println("ip:"+ ip + ",省份:" + province + ",城市:" + city); return ipAddress; } return null; } @Data public static class IpAddress{ private String province; private String city; } public static void main(String[] args) { System.out.println(getAddress("36.25.225.250")); } }
3、测试结果
测试ip:36.25.225.250
返回数据:
ip:36.25.225.250,省份:浙江省,城市:湖州市
iptes.IpAddress(province=浙江省, city=湖州市)
