Tutorial on querying geographic location information based on IP address in python development

Because my website needs to query the source IP address to query its geographical location information. Therefore, I used some things to query geographical location information based on IP addresses, and now I have shared some accumulated things in this area.
First of all, when I first learned Python a few years ago, I have already written a similar blog (but it is not comprehensive enough). For details, see Python to get local IP addresses and locations.

Some APIs for querying the location and operator information based on the IP address are as follows (based on my limited experience ):
1. Taobao API (recommended): http://ip.taobao.com/service/getIpInfo.php? Ip = 110.84.0.129
2. freegeoip.net (recommended): http://freegeoip.net/json/110.84.0.129, which also provides latitude and longitude information (but not necessarily accurate)
3. Sina API: http://int.dpool.sina.com.cn/iplookup/iplookup.php? Format = json & ip = 110.84.0.129
4. Tencent web page query: http://ip.qq.com/cgi-bin/searchip? Searchip1 = 110.84.0.129
5. ip.cn webpage: http://www.ip.cn/index.php? Ip = 110.84.0.129
6. Ip-api.com: http://ip-api.com/json/110.84.0.129 (looks pretty good, it looks like a direct return of Chinese city information, documentation in ip-api.com/docs/api:json)
7. Http://www.locatorhq.com/ip-to-location-api/documentation.php (this need to register to use, haven't used it)

(2nd freegeoip.net website and IP data generation, code in: https://github.com/fiorix/freegeoip)

Why are two of them recommended for Web queries? The two reasons are as follows: first, they provide relatively accurate information, and second, they use automatic page information capture (may use PhantomJS I have previously written) it is also easy to write it into the program as an API.

Based on the IP address to query the geographic location information, I wrote it into a more common Python library (provides the APIs for the preceding four query methods: 1, 2, 4, and 5 ), you can query the region and ISP information based on the IP address. For the specific code, see:
Https://github.com/smilejay/python/blob/master/py2013/iplocation.py
Note that webdriver and PhantomJS are used for parsing ip.cn web pages.

The code is as follows:
