[已解决]python60讲下载图片地址 出现timeout的错误

况qiqi

代码如下：
import urllib.request
import re

def open_url(url):
    req=urllib.request.Request(url)
    req=req.add_header('User-Agent','Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.221 Safari/537.36 SE 2.X MetaSr 1.0')
    response=urllib.request.urlopen(req)
    html=response.read().decode('utf-8')
    return html

def get_img(html):
    p=r'<img class="BDE_Image" src="[^"]+\.jpg"'
    imglist=re.findall(p,html)

    for each in imglist:
        print(each)
   
if __name__=='__main__':
    url='https://tieba.baidu.com/p/3563409202'
    get_img(open_url(url))


错误：
Traceback (most recent call last):
  File "E:/pythonpro/lesson53.py", line 20, in <module>
    get_img(open_url(url))
  File "E:/pythonpro/lesson53.py", line 7, in open_url
    response=urllib.request.urlopen(req)
  File "D:\Python36_64\lib\urllib\request.py", line 223, in urlopen
    return opener.open(url, data, timeout)
  File "D:\Python36_64\lib\urllib\request.py", line 517, in open
    req.timeout = timeout
AttributeError: 'NoneType' object has no attribute 'timeout'

我看了一下错误是在打开网址的时候，是百度加了什么反爬的机制吗？？搞不懂a
