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; /** * 根据IP地址获取详细的地域信息 * 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 * @File AddressUtils.java * @Package org.gditc.weicommunity.util * @Description TODO * @Copyright Copyright © 2014 * @Site https://github.com/Cryhelyxx * @Blog http://blog.csdn.net/Cryhelyxx * @Email [email protected] * @Company GDITC * @Date 2014年11月6日下午1:46:37 * @author Cryhelyxx * @version 1.0 */ public class AddressUtils { /** * * @param content * 请求的参数格式为：name=xxx&pwd=xxx * @param encoding * 服务器端请求编码。如GBK,UTF-8等 * @return * @throws UnsupportedEncodingException */ public static String getAddresses(String content, String encodingString) throws UnsupportedEncodingException { // 这里调用淘宝API String urlStr = "http://ip.taobao.com/service/getIpInfo.php"; // 从http://whois.pconline.com.cn取得IP所在的省市区信息 String returnStr = getResult(urlStr, content, encodingString); if (returnStr != null) { // 处理返回的省市区信息 System.out.println("(1) unicode转换成中文前的returnStr : " + returnStr); returnStr = decodeUnicode(returnStr); System.out.println("(2) unicode转换成中文后的returnStr : " + returnStr); String[] temp = returnStr.split(","); if(temp.length URL url = null; HttpURLConnection connection = null; try { url = new URL(urlStr); connection = (HttpURLConnection) url.openConnection();// 新建连接实例 connection.setConnectTimeout(2000);// 设置连接超时时间，单位毫秒 connection.setReadTimeout(2000);// 设置读取数据超时时间，单位毫秒 connection.setDoOutput(true);// 是否打开输出流 true|false connection.setDoInput(true);// 是否打开输入流true|false connection.setRequestMethod("POST");// 提交方法POST|GET connection.setUseCaches(false);// 是否缓存true|false connection.connect();// 打开连接端口 DataOutputStream out = new DataOutputStream(connection .getOutputStream());// 打开输出流往对端服务器写数据 out.writeBytes(content);// 写数据,也就是提交你的表单 name=xxx&pwd=xxx out.flush();// 刷新 out.close();// 关闭输出流 BufferedReader reader = new BufferedReader(new InputStreamReader( connection.getInputStream(), encoding));// 往对端写完数据对端服务器返回数据 // ,以BufferedReader流来读取 StringBuffer buffer = new StringBuffer(); String line = ""; while ((line = reader.readLine()) != null) { buffer.append(line); } reader.close(); return buffer.toString(); } catch (IOException e) { e.printStackTrace(); } finally { if (connection != null) { connection.disconnect();// 关闭连接 } } return null; } /** * unicode 转换成中文 * * @author fanhui 2007-3-15 * @param theString * @return */ public static String decodeUnicode(String theString) { char aChar; int len = theString.length(); StringBuffer outBuffer = new StringBuffer(len); for (int x = 0; x aChar = theString.charAt(x++); if (aChar == 'u') { int value = 0; for (int i = 0; i case '0': case '1': case '2': case '3': case '4': case '5': case '6': case '7': case '8': case '9': value = (value aChar = '\t'; } else if (aChar == 'r') { aChar = '\r'; } else if (aChar == 'n') { aChar = '\n'; } else if (aChar == 'f') { aChar = '\f'; } outBuffer.append(aChar); } } else { outBuffer.append(aChar); } } return outBuffer.toString(); } // 测试 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":"\u4e2d\u56fd","country_id":"CN","area":"\u534e\u5357","area_id":"800000","region":"\u5e7f\u4e1c\u7701","region_id":"440000","city":"\u5e7f\u5dde\u5e02","city_id":"440100","county":"\u8d8a\u79c0\u533a","county_id":"440104","isp":"\u7535\u4fe1","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
