Python：URLError：

Question

操作系统：Windows 7; Python 2.7.6使用Python GUI Shell

我正在尝试使用Python脚本抓取网站，有几位作者使用urllib和urllib2库。为了将URL的HTML内容存储在变量中，我看到了类似的方法：

import urllib2

c=urllib2.urlopen('http://en.wikipedia.org/wiki/Rocket_Internet')

contents=c.read( )

print contents

urlopen在120+秒后生成错误：

Traceback (most recent call last):
  File "H:/Movie_Knowledge_Graph/crawl.py", line 4, in <module>
    c=urllib2.urlopen('http://en.wikipedia.org/wiki/Rocket_Internet')
  File "C:\Python27\lib\urllib2.py", line 127, in urlopen
    return _opener.open(url, data, timeout)
  File "C:\Python27\lib\urllib2.py", line 404, in open
    response = self._open(req, data)
  File "C:\Python27\lib\urllib2.py", line 422, in _open
    '_open', req)
  File "C:\Python27\lib\urllib2.py", line 382, in _call_chain
    result = func(*args)
  File "C:\Python27\lib\urllib2.py", line 1214, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "C:\Python27\lib\urllib2.py", line 1184, in do_open
    raise URLError(err)
URLError: <urlopen error [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond>

我知道在使用代理时我们必须相应地设置环境变量。但是，我正在使用我的家庭WiFi网络，这需要无代理。我也尝试过urllib，但它会产生同样的错误。
