问题描述

我已经在这个网站上发帖了，并得到了非常有用的指导，我带着另一个问题回来了.

I have posted to this site and received really helpful guidance, i return with another question.

我哪里出错了，我很确定这是从各个站点访问信息所必需的.在这种情况下，芝商所集团.

Where have i gone wrong here, I was prettty sure this is what is required to access information from various sites. In this case, the CME Group.

   import urllib2

url = "http://www.cmegroup.com/trading/energy/natural-gas/natural-gas.html"
request= urllib2.Request(url)
handle = urllib2.urlopen(request)
content = handle.read()
splitted_page = content.split("<span class=\"cmeSubHeading\">", 1);
splitted_page = splitted_page[1].split("</span>", 1)
print splitted_page[0]

读取错误，

HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 403: Forbidden

非常感谢您.

推荐答案

实际上问题是他们屏蔽了所有没有用户代理的人

Actually the problem is that they block everyone who doesn't have a user-agent

import urllib2

request = urllib2.Request("http://www.cmegroup.com/trading/energy/natural-gas/natural-gas.html", None, {'User-Agent': 'Mozilla/5.0'})
content = urllib2.urlopen(request).read()
splitted_page = content.split("<span class=\"cmeSubHeading\">", 1);
splitted_page = splitted_page[1].split("</span>", 1)
print splitted_page[0]
