根據ip地址查詢地址資訊

用的是http://ip.taobao.com/service/getIpInfo.php介面。
這個也是網上找的，但是我已經修改測試過了，是可用的，在這裡先感謝原作者。

今天看了之後發現上面的程式碼似乎有些多餘，對於一些情況不用寫的那麼複雜，下面這個相當於簡化版（即沒有編碼處理），僅做參考：
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; import java.util.Map; /** * Created by czy on 2018/11/23. * 地址相關 */ public class AddressUtil { /** * @param ipAddr ip地址 * @return 位置資訊 */ public static Map<String, Object> getAddressByIP(String ipAddr) { String requestURL = "http://ip.taobao.com/service/getIpInfo.php?ip=" + ipAddr; //從 http://whois.pconline.com.cn 取得IP所在的省市區資訊 URL url = null; HttpURLConnection connection = null; BufferedReader reader = null; try { url = new URL(requestURL); connection = (HttpURLConnection) url.openConnection(); connection.setConnectTimeout(2000); connection.setReadTimeout(2000); connection.connect(); reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); String lines; StringBuilder sb = new StringBuilder(); while ((lines = reader.readLine()) != null) { sb.append(lines); } reader.close(); Map<String, Object> result = FormatUtil.parseJSON2Map(sb.toString()); return result; } catch (MalformedURLException ex) { ex.printStackTrace(); return null; } catch (IOException ex) { ex.printStackTrace(); return null; } finally { connection.disconnect(); } } public static void main(String[] args) { Map<String, Object> addressByIP = getAddressByIP("43.224.80.0"); if (addressByIP == null) { System.out.println("根據IP獲取地址出錯"); return; } System.out.println(addressByIP.toString()); Map<String, Object> data = (Map<String, Object>) addressByIP.get("data"); System.out.println(data.toString()); String area = String.valueOf(data.get("area"));//區域-華南華北等 String area_id = String.valueOf(data.get("area_id")); String city = String.valueOf(data.get("city"));//城市 String city_id = String.valueOf(data.get("city_id")); String country = String.valueOf(data.get("country"));//國家 String country_id = String.valueOf(data.get("country_id")); String county = String.valueOf(data.get("county"));//縣 String county_id = String.valueOf(data.get("county_id")); String isp = String.valueOf(data.get("isp"));//運營商 String isp_id = String.valueOf(data.get("isp_id")); String region = String.valueOf(data.get("region"));//省份 String region_id = String.valueOf(data.get("region_id")); System.out.println(area + "--" + country + "--" + region + "--" + city + "--" + county + "--" + isp); } }
下面是簡化版對應的返回結果：
