Get Region Information from IP Address with Taobao API

　　通过淘宝的API "http://ip.taobao.com/service/getIpInfo.php?ip=*.*.*.*" 来获得你要查询的IP地址的国家,地区,城市,ISP等

地理位置信息.

　　Python代码如下:

#!/usr/bin/python2.7
#File: IP2Region.py
#Author: lxw
#Time: 2014-12-03
#Usage: Get the location information from IP.
#Reference:http://smilejay.com/2014/05/python-get-geoinfo-from-ip/
#The data format that location_taobao.getLocation() returns is as follow:
#{
#    "code":0,
#    "data":{
#            "country":"\u53f0\u6e7e",
#            "country_id":"TW",
#            "area":"",
#            "area_id":"",
#            "region":"\u53f0\u6e7e\u7701",
#            "region_id":"TW_01",
