在项目开发中，需要在登录日志或者操作日志中记录客户端ip所在的地理位置。
目前根据ip定位地理位置的第三方api有好几个，淘宝、新浪、百度等，这三种其实也有些缺点的：
在此整理一下，便于后期使用。

根据以上使用指南，注册百度账号，成为地图开放平台开发者，获取密钥（AK），根据服务文档使用。

把上边的百度密钥换成你自己的，下边是API返回的json数据格式。

address: "北京市", #简要地址
address_detail: #详细地址信息
{
city: "北京市", #城市
city_code: 131, #百度城市代码
district: "", #区县
province: "北京市", #省份
street: "", #街道

},
point: #当前城市中心点
{
x: "116.39564504",
y: "39.92998578"
}
},
status: 0 #返回状态码

}3、测试结果
测试ip：36.25.225.250
返回数据：
ip：36.25.225.250，省份：浙江省，城市：湖州市
iptes.IpAddress(province=浙江省, city=湖州市)
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
