淘宝返回的数据为：

{"code":0,"data":{"country":"u4e2du56fd","country_id":"CN","area":"u534eu4e1c","area_id":"300000","region":"u5c71u4e1cu7701","region_id":"370000","city":"u4e1cu8425u5e02","city_id":"370500","county":"","county_id":"-1","isp":"u8054u901a","isp_id":"100026","ip":"60.214.183.158"}}

用法：

复制代码 代码如下:

String arr1 = GetAddressByIp.GetAddressByIp("120.192.182.1");

System.out.println(arr1);

详细请看代码
