In the morning, the project manager said that it is necessary to add a user ip home location query function, and then search the Internet for half a day, and work out a relatively simple method to return address json data through the interface
Baidu interface, Sina interface, Taobao ip interface is used here
Get IP location through Taobao IP address Library
GET: http://ip.taobao.com/service/getIpInfo.php?ip=[ip address string]
Response information: (json format) country, province (autonomous region or municipality directly under the central government), city (county), operator, etc
