- OfStack
There are many interfaces on the Internet that can query the specific location through ip, as follows:
Get the IP location through Taobao IP address library
Request interface (GET) : http: / / ip taobao. com/service/getIpInfo php & # 63; ip=[ip address string]
Response information :(json format) country, province (autonomous region or municipality), city (county), operator
Return data format:
{ " code " :0, " data " :{ " ip " : " 210.75.225.254 " , " country " : " \u4e2d\u56fd " , " area " : " \u534e\u5317 " ,
" region " : " \u5317\u4eac\u5e02 " , " city " : " \u5317\u4eac\u5e02 " , " county " : "" , " isp " : " \u7535\u4fe1 " ,
" country_id " : " 86 " , " area_id " : " 100000 " , " region_id " : " 110000 " , " city_id " : " 110000 " ,
" county_id " : " -1 " , " isp_id " : " 100017 " }}
Where the value of code means 0: success, 1: failure.
Sina interface: http: / / int dpool. sina. com. cn/iplookup/iplookup php & # 63; format = json
&
ip=218.192.3.42
The return value
var remote_ip_info = { " ret " :1, " start " : " 218.192.0.0 " , " end " : " 218.192.7.255 " , " country " : " \u4e2d\u56fd " , " province " : " \u5e7f\u4e1c " , " city " : " \u5e7f\u5dde " , " district " : "" , " isp " : " \u6559\u80b2\u7f51 " , " type " : " \u5b66\u6821 " , " desc " : " \u5e7f\u5dde\u5927\u5b66\u7eba\u7ec7\u670d\u88c5\u5b66\u9662 " };
