'NoneType' 对象在使用 beautifulsoup 进行网络爬行时没有属性'text'

Question

我在尝试抓取网络数据时出错，错误消息显示

标签信息：“NoneType”对象没有“文本”属性

网站在这里 https://www.target.com/p/nong-shim-noodle-bowl-soup-spicy-kimchi-flavor-3-03oz/-/A-15137591#lnk=sametab

        try:
            label_info = soup.find('div', {'class': 'h-bg-white h-margin-a-default'})
            if debug: print('Label info:',label_info.text)
            if debug: print('')
        except Exception as e:
            label_info = ''
            if debug: print("Label info:", e)
            pass

谁能指导我为什么这不起作用？

Answer 1

您可以将 CSS 类指定为字符串列表，而不是一个字符串：

import requests
from bs4 import BeautifulSoup

url = 'https://www.target.com/p/nong-shim-noodle-bowl-soup-spicy-kimchi-flavor-3-03oz/-/A-15137591#lnk=sametab'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

print(soup.find('div', {'class': ['h-bg-white', 'h-margin-a-default']}).get_text(strip=True, separator='\n'))

打印：
