爬取糗图百科图片求助

import requests
import re
if __name__ == '__main__':
    url='https://www.qiushibaike.com/imgrank/page/2/'
    headers={
      'User-Agent':'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Mobile Safari/537.36'
    }

    response=requests.get(url=url,headers=headers).text
    print(response)
    regex ='div class="author clearfix">.*?<img src="(.*?)\?.*?</div>'
    image_src_list=re.findall(regex,response,re.S)
    print(image_src_list)

为啥image_scr_list是空列表呢

正则不对呗，参考代码：

import requests
import re

if __name__ == '__main__':
    url = 'https://www.qiushibaike.com/imgrank/page/2/'
    headers = {
      'User-Agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Mobile Safari/537.36'}

    response = requests.get(url=url, headers=headers).text
    print(response)
    regex = '<img src="(//pic.qiushibaike.com/system/pictures.+?)"'
    image_src_list = re.findall(regex, response, re.S)
    for i in image_src_list:
      print('https:' + i)
