照着56讲敲代码，为啥报错
哪位大神帮我看看import urllib.request
import os
def url_open(url):
req = urllib.requests.Request(url)
req.add_header('User-Agent','Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36')
response = urllib.request.urlopen
html = response.read()
return html
def get_page(url):
html = url_open(url).decode(utf-8)
a = html.find('current-comment-page')+23
b = html.find(']',a)
return html
def find_img(url):
html = url_open(url).decode(utf-8)
img_addrs = []
a = html.find('img src = ')
while a != -1:
b = html.find('.jpg',a,a+255)
if b != -1:
img_addrs.append('https:'+html)
else:
b = a + 9
a = html.find('img src = ',b)
return img_addrs
def save_imgs(folder,img_addrs):
for each in img_addrs:
filename = each.split('/')[-1]
with open(filename,'wb')as f:
img = url_open(each)
f.write(img)
def download_mm(folder='ooxx',pages=10):
os.mkdir(folder)
os.chdir(folder)
url = 'http://jandan.net/ooxx/'
page_num = int(get_page)
for i in range(pages):
page_num -= i
page_url = url + 'page-' + str(page_num) + '#comments'
find_addrs = find_imgs(page_url)
save_imgs(img_addrs)
if __name__ == "__main__":
download_mm()
有人在吗
