writeUlistfile(uinfo1,'各种油产量初.csv')

报错

Traceback (most recent call last):
  File "D:\Users\Qi520503\Desktop\shiyou\未命名3.py", line 45, in <module>
    fillUnivlist(uinfo1,html1)
  File "D:\Users\Qi520503\Desktop\shiyou\未命名3.py", line 29, in fillUnivlist
    for tr in soup.find('tbody').children:
AttributeError: 'NoneType' object has no attribute 'children'

解决方案：
加入urllib3模块，关闭ssl警告。

代码如下：

import requests
from bs4 import BeautifulSoup
import bs4
import csv
import urllib3
urllib3.disable_warnings()

def getHTMLText(url):#爬取网站数据
    try:
        r = requests.get(url, timeout = 30,verify=False)
        r.raise_for_status()
        r.encoding = r.apparent_encoding
        return r.text
    except:
        return '爬取失败'

运行后无报错，爬取的数据正常保存在csv文件中。
