使用 Beautifulsoup 4 进行网页抓取 - 提取联系信息

第二个样式标签包含 css 代码，其中icon-xx 属性的顺序定义了该属性与哪个数字匹配。这用于在网页上加载具有此编号的图像，因此没有要抓取的数字。解决方案是 1) 根据它们在 css 字符串中的顺序将 icon-xx 属性映射到数字；2）在html正文中找到电话号码范围并检索匹配的号码：

import requests
from bs4 import BeautifulSoup

url = 'https://www.justdial.com/Pune/Sunrise-Enterprises-Budhwar-Peth/020PXX20-XX20-130817131104-Z3I2_BZDET?xid=UHVuZSBFbGVjdHJvbmljIENvbXBvbmVudCBEZWFsZXJz'
r = requests.get(url, headers={'User-Agent' : "Mozilla/5.0 (Windows NT 6.1; Win64; x64)"})
soup = BeautifulSoup(r.text, "html.parser")

text = soup.find_all('style', {"type": "text/css"}, text=True)[1]
data = text.contents[0].split('smoothing:grayscale}', 1)[1].split('\n')[0]
icon_items = [i.split(':')[0] for i in data.split('.') if len(i)>0]
items = ['0','1','2','3','4','5','6','7','8','9','+','-',')','(']
full_list = dict(zip(icon_items, items))

phone_numbers = soup.find_all('span',{'class':'telnowpr'})
for i in phone_numbers:
    numbers = i.find_all('span')
    number = [full_list[y.attrs['class'][1]] for y in numbers]
    print("phone number: " + ''.join([str(elem) for elem in number]) )

结果：

phone number: 07947197693
phone number: 07947197693
phone number: 07947197693
