几个通过IP查询地理信息的网站

1.  这是个已经shutdown的网站，曾经提供JSON IP and GeoIP REST API
2.  这个网站很不错，提供xml/json/csv的输出

root@kali:/usr/local/src/py/network# curl freegeoip.net/csv/123.161.***.***
123.161.***.***,CN,China,41,Henan,Zhengzhou,,Asia/Shanghai,34.68,113.53,0
root@kali:/usr/local/src/py/network# curl freegeoip.net/xml/123.161.***.***
<Response>
    <IP>123.161.***.***</IP>
    <CountryCode>CN</CountryCode>
    <CountryName>China</CountryName>
    <RegionCode>41</RegionCode>
    <RegionName>Henan</RegionName>
    <City>Zhengzhou</City>
    <ZipCode></ZipCode>
    <TimeZone>Asia/Shanghai</TimeZone>
    <Latitude>34.6836</Latitude>
    <Longitude>113.5325</Longitude>
    <MetroCode>0</MetroCode>
</Response>
root@kali:/usr/local/src/py/network# curl -s freegeoip.net/json/123.161.***.*** |python3 -m json.tool
{
    "ip": "123.161.***.***",
    "country_code": "CN",
    "country_name": "China",
    "region_code": "41",
    "region_name": "Henan",
    "city": "Zhengzhou",
    "zip_code": "",
    "time_zone": "Asia/Shanghai",
    "latitude": 34.6836,
    "longitude": 113.5325,
    "metro_code": 0
}

3. 这个网站给我的感觉是速度比较快的,也是提供返回格式最多的


如果仔细比较这上两个网站，你会发现ip-api.com 的输出内容会多一些，多输出3个column, 其中一个as, 这个应该是BGP路由协议的自治域。

root@kali:/usr/local/src/py/network/scraper# curl -s  http://ip-api.com/xml/123.161.***.***

    "zip": ""
}

4.  这个网站比较一般，没什么特色而且很不规范。我写了个代码来parse这些信息，才发现其坑人的地方，

里面的span用法统一，输出的text除了第一个以外都放在span标签内，而一个是把text放在下面。

import requests
from bs4 import BeautifulSoup
from lxml.etree import HTML
url="en/?ip="
ipaddr="123.161.***.***"

response=requests.get(url+ipaddr)
#print(response.content)
soup=BeautifulSoup(response.content,'lxml')
#print(soup.prettify())

contents=soup.find_all('div',class_='data-item')
d={}
key=contents[0].span.text.strip()
value=contents[0].td.text.strip()
d[key]=value
for i in contents[1:]:
    key=i.span.text.strip()
    value=i.span.find_next().get_text().strip()
    d[key]=value

for key in d:
    print(key,d[key])
