java_获取指定ip的定位

Posted 2021-12-02 lavender-pansy

因为自己网站后台做了一个进站ip统计，之前只是获取了ip，这次优化了下，把ip的大致区域弄出来了

废话不多说，进正题

首先要用到几个网络大头的api

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

接下来用json解析返回的数据就好
下面直接上解析源码（不是网站的源码，是之前java测试的源码，原理一样）

package exe;

import net.sf.json.JSONObject;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Scanner;

public class get_analyse_ip {
    /**

    public static void main(String[] args) {
        HttpURLConnection connection ;
        String api = "http://ip.taobao.com/service/getIpInfo.php";
        String connect_symbol = "?";
        String front_name = "ip=";
        Scanner sc = new Scanner(System.in);
        String real_ip = sc.next();
        URL url ;
        BufferedReader bf ;
        StringBuffer sb = new StringBuffer();
        try {
            url = new URL(api+connect_symbol+front_name+real_ip);
            connection = (HttpURLConnection)url.openConnection();
            bf = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8"));
            String line = "";
            while(null!=(line = bf.readLine())){
                sb.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
//        System.out.println(sb);
        JSONObject dataObject = JSONObject.fromObject(sb.toString());
        JSONObject jsonObject= dataObject.getJSONObject("data");
        System.out.println(jsonObject.toString());
        System.out.println("ip:"+jsonObject.get("ip"));
        System.out.println("country:"+jsonObject.get("country"));
        System.out.println("area:"+jsonObject.get("area"));
        System.out.println("region:"+jsonObject.get("region"));
        System.out.println("county:"+jsonObject.get("county"));
        System.out.println("isp:"+jsonObject.get("isp"));
　　　　 System.out.println("city:"+jsonObject.get("city"));
        System.out.println("country_id:"+jsonObject.get("country_id"));
        System.out.println("area_id:"+jsonObject.get("area_id"));
        System.out.println("region_id:"+jsonObject.get("region_id"));
        System.out.println("city_id:"+jsonObject.get("city_id"));
        System.out.println("county_id:"+jsonObject.get("county_id"));
        System.out.println("isp_id:"+jsonObject.get("isp_id"));

    }
}

要导入json第三方jar包，方法自行百度，在此不赘述

 

希望对大家有所帮助
