[已解决]一个难解的问题

罗世杰

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):
  File "C:\Users\luoshijie\Desktop\文件夹\python计算机语言编程\网络爬虫（罗踢1）.py", line 27, in <module>
    html = download_page(url)

    response = urllib.request.urlopen(request)

    return opener.open(url, data, timeout)

    response = meth(req, response)
  File "C:\Users\luoshijie\AppData\Local\Programs\Python\Python37\lib\urllib\request.py", line 641, in http_response
    'http', request, response, code, msg, hdrs)

    return self._call_chain(*args)

    result = func(*args)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 404: Not Found

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}

我奉劝你使用第三方库requests，既简单又实用。
