IP工具类-自己动手做个ip解析器

IP工具类-自己动手做个ip解析器

一、资料准备

导入依赖包：

下载地址：http://yunpan.cn/cLHfYZQMn65Qq  访问密码 6090

如果不用阿里巴巴的请求。则不用导入阿里巴巴的jar包。只需导入解析纯真数据库需要的jar即可。

JSon包可导可不导。

二、实现代码

方法一、通过查询数据库实现

方法二、通过调用alibaba的ip数据库查询得出。

以下是详细的实现代码：

package com.souvc.common.base;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.InetAddress;
import java.net.MalformedURLException;
import java.net.ProtocolException;
import java.net.URL;
import java.net.UnknownHostException;

import javax.servlet.http.HttpServletRequest;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.handsome.ip.IPSeeker;

方法三：通过百度api查询得出。

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Map;

import net.sf.json.JSONObject;

public class TestIP {
    
    
    public static void main(String[] args) {
        String httpUrl = "http://apis.baidu.com/apistore/iplookupservice/iplookup";
        String httpArg = "ip=117.89.35.58";
        String jsonResult = request(httpUrl, httpArg);
        //System.out.println(jsonResult);
        JSONObject jasonObject = JSONObject.fromObject(jsonResult);
        System.out.println(jasonObject);
        System.out.println(jasonObject.get("errNum"));
        System.out.println(jasonObject.get("errMsg"));
        System.out.println(jasonObject.get("retData"));
        Map map=(Map) jasonObject.get("retData");
        System.out.println(map.get("ip"));

        System.out.println(map.get("city"));
        System.out.println(map.get("district"));

    }
    
    /**

     * @return 返回结果
     */
    public static String request(String httpUrl, String httpArg) {
        BufferedReader reader = null;
        String result = null;
        StringBuffer sbf = new StringBuffer();
        httpUrl = httpUrl + "?" + httpArg;
        try {
            URL url = new URL(httpUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            // 填入apikey到HTTP header
            connection.setRequestProperty("apikey",  "xxx");
            connection.connect();
            InputStream is = connection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            String strRead = null;
            while ((strRead = reader.readLine()) != null) {
                sbf.append(strRead);
                sbf.append("
");
            }
            reader.close();
            result = sbf.toString();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }
    
}

注意，替换成自己的百度api的apikey 。
