JAVA联网查询IP地址归属，java联网ip归属,原理是根据淘宝提供的se

原理是根据淘宝提供的service查询IP的归属地并且解析http请求返回的json串。我之前也是伸手党，现在也给伸手党提供下方便。淘宝返回的数据为：{"code":0,"data":{"country":"\u4e2d\u56fd","country_id":"CN","area":"\u534e\u4e1c","area_id":"300000","region":"\u5c71\u4e1c\u7701","region_id":"370000","city":"\u4e1c\u8425\u5e02","city_id":"370500","county":"","county_id":"-1","isp":"\u8054\u901a","isp_id":"100026","ip":"60.214.183.158"}}用法：Stringarr1=GetAddressByIp.GetAddressByIp("120.192.182.1");System.out.println(arr1);详细请看代码```java
