2. Programming ideas

  Copy the IP address you want to query to variable a. By observing the changes of the URL of the website before and after the query, a URL link that can be queried after submitting the IP address is constructed based on the rules. After the content is obtained, the fragment output can query the IP address Attribution.

3. Complete code

import requests

def getHTMLText(url):
    try:
        kv={
    
    'user-agent':'Mozilla/5.0'}
        r=requests.get(url,headers=kv)
        r.raise_for_status()
        r.encoding=r.apparent_encoding
        print(r.text[2000:3000])#分片查看相应字节
    except:
        print("爬取失败")

def main():
    a=input("请输入要查询的IP地址：")
    url='https://ipchaxun.com/'+a
    getHTMLText(url)

main()
