python MAC地址查询

 使用公网的查询网页抓爬方式

from bs4 import BeautifulSoup
import requests

mac="88-46-04-46-75-34"
url="https://mac.bmcx.com/%s__mac/" % mac
html=requests.get(url,verify=False).content
html=html.decode('utf-8')
html=BeautifulSoup(html,features="html.parser")
tr=html.select("#main_content table td table tr")
for row in tr:
    if "组织名称" in row.text:
        td=row.select("td")
        print(td[1].text)

使用MAC字典

import re
mac={}
f=open("../mac.txt",mode='r',encoding='utf-8')
stream=f.read()
pattern="(S+)s+(hex)s+([^n]+)"
pattern=re.compile(pattern)
search=pattern.findall(stream)
for s in search:
    mac[s[0]]=s[1]

def get(m):
    m=m[:8]
    if m in mac.keys():
        return mac[m]
    else:
        return "未知"
