用百度搜索获取 IP 地址的归属地（已经失效）

思路：把 IP 地址当关键词拼上百度的搜索链接，然后用正则匹配想要的信息。

代码：

import re
import requests

requests.packages.urllib3.disable_warnings()


def get_ipv4(ip):
    """
    获取 IPv4
    :param ip:
    :return:
    """
    # IP patterns
    ipv4_re = r'(?:25[0-5]|2[0-4]\d|[0-1]?\d?\d)(?:\.(?:25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}'
    # ipv6_re = r'\[[0-9a-f:\.]+\]'  # (simple regex, validated later)
    ipv4 = re.search(ipv4_re, ip)
    if ipv4:
        return ipv4.group()
    return ip


def ip_location_baidu(ip):
    """
    从 百度搜索 获取 IP 的 归属地
    :param ip:
    :return:
    """
    headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) \

    }
    ipv4 = get_ipv4(ip)
    url = r'https://www.baidu.com/s?wd=%s' % ipv4
    result = requests.get(url=url, headers=headers, verify=False).text
    re_compile = re.compile("IP地址:&nbsp;%s</span>(.*?)</td></tr></table>" % ipv4, re.S)
    ip_location = re.findall(re_compile, result)
    if ip_location:
        ip_location = ip_location[0].replace("\t", "").replace("\n", "").replace(" ", "")
        ip_location = ip_location.replace("省", "·").replace("市", "").replace("电信", "").replace("联通", "").replace(
            "移动", "")
        return ip_location
    else:
        return None


if __name__ == "__main__":
    print(ip_location_baidu("106.11.153.104"))
