问题描述：
获取访问IP的地址数据并写入数据库
解决方案：
使用http://ip.taobao.com/service/getIpInfo.php?ip= 接口
返回结果样例：
{
"code":0,
"data":{
"ip":"117.147.169.51",
"country":"中国","area":"",
"region":"浙江","city":"绍兴",
"county":"XX",
"isp":"移动",
"country_id":"CN",
"area_id":"",
"region_id":"330000",
"city_id":"330600",
"county_id":"xx",
"isp_id":"100025"
}
}
