def open_url(url):
　　req = urllib.request.Request(url)
　　req.add_header('User-Agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36')

　　page = urllib.request.urlopen(req)
　　html = page.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:
　　　　file_name = each.split('/')[-1]
　　　　urllib.request.urlretrieve(each, file_name)
if __name__ == '__main__':
　　url = 'https://tieba.baidu.com/p/5272413637?red_tag=0606091703'
　　get_img(open_url(url))

执行程序结果
