【www.bbyears.com--python】
因本人的网站需要查询源IP拿来查询其地理位置信息。所以，我就用到了根据IP查询地理位置信息的一些东西，现在将这方面积累的一点东西共享出来。
首先要说的是，几年前刚学Python那会儿，已经写过类似的一篇博客（只是写的不够全面），见：Python获取本地的IP和所在地
根据IP查询所在地、运营商等信息的一些API如下（根据我有限的一点经验）：
1. 淘宝的API（推荐）：http://ip.taobao.com/service/getIpInfo.php?ip=110.84.0.129
2. 国外freegeoip.net（推荐）：http://freegeoip.net/json/110.84.0.129 这个还提供了经纬度信息（但不一定准）
3. 新浪的API：http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=110.84.0.129
4. 腾讯的网页查询：http://ip.qq.com/cgi-bin/searchip?searchip1=110.84.0.129
5. ip.cn的网页：http://www.ip.cn/index.php?ip=110.84.0.129
6. ip-api.com： http://ip-api.com/json/110.84.0.129 （看起来挺不错的，貌似直接返回中文城市信息，文档在 ip-api.com/docs/api:json）
7. http://www.locatorhq.com/ip-to-location-api/documentation.php （这个要注册才能使用，还没用过呢）
（第2个freegeoip.net的网站和IP数据的生成，代码在：https://github.com/fiorix/freegeoip）
为什么其中第4、5两个是网页查询也推荐了呢？是因为两方面原因，一是它们提供的信息比较准，二是使用了页面信息自动抓取（可能会用到我曾经写过的PhantomJS）也容易将其写到程序中成为API。
根据IP查询地理位置信息，我将其写成了一个较为通用的Python库（提供了前面提到的1、2、4、5等4种查询方式的API），可以根据IP查询到地域信息和ISP信息，具体代码见：
https://github.com/smilejay/python/blob/master/py2013/iplocation.py
注意其中对ip.cn网页的解析用到了webdriver和PhantomJS.
