一个难解的问题
代码如下：import urllib
import urllib.request
import re
def download_page(url):
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
data = response.read( )
return data
def get_image(html):
regx = r'http://{\S}*\.jpg'
pattern = re.compile(regx)
get_img = re.findall(pattern,repr(html))
num = 1
for img in get_img:
image = download_page(img)
with open('%s.jpg'%num,'wd') as fp:
fp.write(image)
num += 1
print('正在下载第%s张图片'%num)
return
url = 'http://pic.yesky.com/451/106166451.shtml'
html = download_page(url)
get_image(html)
报错如下：
Traceback (most recent call last):

html = download_page(url)

请大神回答一下怎么回事。还有，谁能看出来我这些代码是干嘛的吗？{奸笑} 此页面不存在，谢谢。
上面写着404，别管下面的妹子图。 我奉劝你使用第三方库requests，既简单又实用。
