java 根据IP地址获取地理位置
java 根据IP地址获取地理位置

一、第三方API

ps:下面参数ip: 218.192.3.42 用于测试

淘宝API:http://ip.taobao.com/service/getIpInfo.php?ip=218.192.3.42

新浪API:http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=218.192.3.42

pconline API:http://whois.pconline.com.cn/

百度API:http://api.map.baidu.com/location/ip?ip=218.192.3.42

二、工具类

AddressUtils.java

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;

    public static void main(String[] args) {
        AddressUtils addressUtils = new AddressUtils();
        // 测试ip 219.136.134.157 中国=华南=广东省=广州市=越秀区=电信
        String ip = \"122.49.20.247\";
        String address = \"\";
        try {
            address = addressUtils.getAddresses(\"ip=\"+ip, \"utf-8\");
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println(address);
        // 输出结果为:广东省,广州市,越秀区
    }
}

三、 测试方法

下面采用单元测试

@Test
public void getAddressByIp() throws Exception {
    // 参数ip
    String ip = \"219.136.134.157\";
    // json_result用于接收返回的json数据
    String json_result = null;
    try {
        json_result = AddressUtils.getAddresses(\"ip=\" + ip, \"utf-8\");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    JSONObject json = JSONObject.fromObject(json_result);
    System.out.println(\"json数据: \" + json);
    String country = JSONObject.fromObject(json.get(\"data\")).get(\"country\").toString();
    String region = JSONObject.fromObject(json.get(\"data\")).get(\"region\").toString();
    String city = JSONObject.fromObject(json.get(\"data\")).get(\"city\").toString();
    String county = JSONObject.fromObject(json.get(\"data\")).get(\"county\").toString();
    String isp = JSONObject.fromObject(json.get(\"data\")).get(\"isp\").toString();
    String area = JSONObject.fromObject(json.get(\"data\")).get(\"area\").toString();
    System.out.println(\"国家: \" + country);
    System.out.println(\"地区: \" + area);
    System.out.println(\"省份: \" + region);
    System.out.println(\"城市: \" + city);
    System.out.println(\"区/县: \" + county);
    System.out.println(\"互联网服务提供商: \" + isp);

    String address = country + \"/\";
    address += region + \"/\";
    address += city + \"/\";
    address += county;
    System.out.println(address);
}

四、 打印结果

下面是eclipse控制台的打印结果
(1) unicode转换成中文前的

returnStr : {\"code\":0,\"data\":{\"country\":\"u4e2du56fd\",\"country_id\":\"CN\",\"area\":\"u534eu5357\",\"area_id\":\"800000\",\"region\":\"u5e7fu4e1cu7701\",\"region_id\":\"440000\",\"city\":\"u5e7fu5ddeu5e02\",\"city_id\":\"440100\",\"county\":\"u8d8au79c0u533a\",\"county_id\":\"440104\",\"isp\":\"u7535u4fe1\",\"isp_id\":\"100017\",\"ip\":\"219.136.134.157\"}}

(2) unicode转换成中文后的

returnStr : {\"code\":0,\"data\":{\"country\":\"中国\",\"country_id\":\"CN\",\"area\":\"华南\",\"area_id\":\"800000\",\"region\":\"广东省\",\"region_id\":\"440000\",\"city\":\"广州市\",\"city_id\":\"440100\",\"county\":\"越秀区\",\"county_id\":\"440104\",\"isp\":\"电信\",\"isp_id\":\"100017\",\"ip\":\"219.136.134.157\"}}
json数据: {\"code\":0,\"data\":{\"country\":\"中国\",\"country_id\":\"CN\",\"area\":\"华南\",\"area_id\":\"800000\",\"region\":\"广东省\",\"region_id\":\"440000\",\"city\":\"广州市\",\"city_id\":\"440100\",\"county\":\"越秀区\",\"county_id\":\"440104\",\"isp\":\"电信\",\"isp_id\":\"100017\",\"ip\":\"219.136.134.157\"}}

国家: 中国
地区: 华南
省份: 广东省
城市: 广州市
区/县: 越秀区
互联网服务提供商: 电信
中国/广东省/广州市/越秀区
