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。
