Question

我正在尝试进一步学习Python，但我遇到了障碍。我无法让urllib2 / urllib正常工作。如果我这样做response = urllib2.urlopen('http://python.org/')我会收到此错误：

    Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    response = urllib2.urlopen('http://python.org/')
  File "C:\Python27\lib\urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "C:\Python27\lib\urllib2.py", line 400, in open
    response = self._open(req, data)
  File "C:\Python27\lib\urllib2.py", line 418, in _open
    '_open', req)
  File "C:\Python27\lib\urllib2.py", line 378, in _call_chain
    result = func(*args)
  File "C:\Python27\lib\urllib2.py", line 1207, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "C:\Python27\lib\urllib2.py", line 1177, 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>

即使像URL = "http://173.194.75.94"后跟f=urllib.urlopen(URL)之类的内容也会出现同样的错误，因此它不是DNS问题。我没有代理或防火墙。除了我的Windows默认防火墙，它一直被禁用。即便如此，我还是将python和pythonw.exe添加到了例外。

有任何线索如何解决这个问题？

使用requests可以让您的生活更轻松;

In [1]: import requests

In [2]: pysite = requests.get('http://python.org/')

In [3]: pysite.status_code
Out[3]: 200

In [4]: pysite.ok
Out[4]: True

In [5]: pysite.text[0:40]
Out[5]: u'<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML'

In [6]: pysite.error

In [7]: pysite.links
Out[7]: {}

In [8]: pysite.reason
Out[8]: 'OK'

当您尝试访问某个网站时，您仍会遇到例外情况。在您的网络上不存在或被阻止：

In [3]: foobar = requests.get('http://foo.bar/')

    632 
    633             except MaxRetryError as e:

ConnectionError: [Errno 8] hostname nor servname provided, or not known

但是ConnectionError异常提供的信息告诉你发生了什么;

In [8]: try:                    
    foobar = requests.get('http://foo.bar/')
except requests.ConnectionError as oops:
    print oops.message
   ...:     
[Errno 8] hostname nor servname provided, or not known
