python使用在線API查詢IP對應的地理位置信息實例

更新時間：2014年06月01日 22:29:05 作者：

這篇文章主要介紹了python使用在線API查詢IP對應的地理位置信息實例,需要的朋友可以參考下

這篇文章中的內(nèi)容是來源于去年我用美國的VPS搭建博客的初始階段，那是有很多惡意訪問，我就根據(jù)access log中的源IP來進行了很多統(tǒng)計，同時我也將訪問量最高的惡意訪問的源IP拿來查詢其地理位置信息。所以，我就用到了根據(jù)IP查詢地理位置信息的一些東西，現(xiàn)在將這方面積累的一點東西共享出來。

根據(jù)IP查詢所在地、運營商等信息的一些API如下（根據(jù)我有限的一點經(jīng)驗）：
1. 淘寶的API（推薦）：http://ip.taobao.com/service/getIpInfo.php?ip=110.84.0.129
2. 國外freegeoip.net（推薦）：http://freegeoip.net/json/110.84.0.129 這個還提供了經(jīng)緯度信息（但不一定準）
3. 新浪的API：http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=110.84.0.129
4. 騰訊的網(wǎng)頁查詢：http://ip.qq.com/cgi-bin/searchip?searchip1=110.84.0.129
5. ip.cn的網(wǎng)頁：http://www.ip.cn/index.php?ip=110.84.0.129
6. ip-api.com： http://ip-api.com/json/110.84.0.129 （看起來挺不錯的，貌似直接返回中文城市信息，文檔在 ip-api.com/docs/api:json）
7. http://www.locatorhq.com/ip-to-location-api/documentation.php （這個要注冊才能使用，還沒用過呢）

（第2個freegeoip.net的網(wǎng)站和IP數(shù)據(jù)的生成，代碼在：https://github.com/fiorix/freegeoip）

為什么其中第4、5兩個是網(wǎng)頁查詢也推薦了呢？是因為兩方面原因，一是它們提供的信息比較準，二是使用了頁面信息自動抓取（可能會用到我曾經(jīng)寫過的PhantomJS）也容易將其寫到程序中成為API。

根據(jù)IP查詢地理位置信息，我將其寫成了一個較為通用的Python庫（提供了前面提到的1、2、4、5等4種查詢方式的API），可以根據(jù)IP查詢到地域信息和ISP信息，具體代碼見：
https://github.com/smilejay/python/blob/master/py2013/iplocation.py
注意其中對ip.cn網(wǎng)頁的解析用到了webdriver和PhantomJS.

復制代碼代碼如下:
