page_info = request.urlopen(page).read().decode('utf-8')

soup = BeautifulSoup(page_info, 'html.parser')

# Beautiful Soup和正则表达式结合，提取出所有图片的链接（img标签中，class=**，以.jpg结尾的链接）

links = soup.find_all('img', "origin_image

for link in links:

print(link.attrs['src'])

# 保存链接并命名，time防止命名冲突

request.urlretrieve(link.attrs['src'], local_path+r'%s.jpg' % time.time())
