1. 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

2. 工具类

3. 测试方法
 

下面采用单元测试
 

 

@Testpublic 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);}



4. 打印结果
 

下面是eclipse控制台的打印结果
