Question

我在Windows XP PC上使用带有VitualBox的Ubuntu 12。我正在使用代理来访问互联网。我可以使用Firefox浏览这些网站，以及下面的脚本：

import urllib2
import json

proxy = urllib2.ProxyHandler({'http': 'http://my-proxy-server:80'})
auth = urllib2.HTTPBasicAuthHandler()
opener = urllib2.build_opener(proxy, auth, urllib2.HTTPHandler)
urllib2.install_opener(opener)

#conn = urllib2.urlopen('http://python.org')
return_str = conn.read()
print return_str

上面的代码一切顺利，但是对于类似的代码，下面的代码不起作用。

import urllib2
import json

proxy = urllib2.ProxyHandler({'http': 'http://my-proxy-server:80'})
auth = urllib2.HTTPBasicAuthHandler()
opener = urllib2.build_opener(proxy, auth, urllib2.HTTPHandler)
urllib2.install_opener(opener)


response = urllib.urlopen('https://api.twitter.com/1.1/search/tweets.json?q=microsoft')
print json.load(response)

错误日志如下。

Traceback (most recent call last):
  File "print.py", line 12, in <module>
    conn = urllib2.urlopen('https://api.twitter.com/1.1/search/tweets.json?q=microsoft')
  File "/usr/lib/python2.7/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.7/urllib2.py", line 400, in open
    response = self._open(req, data)
  File "/usr/lib/python2.7/urllib2.py", line 418, in _open
    '_open', req)
  File "/usr/lib/python2.7/urllib2.py", line 378, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.7/urllib2.py", line 1215, in https_open
    return self.do_open(httplib.HTTPSConnection, req)
  File "/usr/lib/python2.7/urllib2.py", line 1177, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 113] No route to host>

请帮帮我。感谢。

尝试创建https处理程序，看看是否能解决问题。

更改此行：

proxy = urllib2.ProxyHandler({'http': 'http://my-proxy-server:80'})

到

proxy = urllib2.ProxyHandler({'https': 'http://my-proxy-server:80'})

并查看是否有效，因为您尝试访问的Twitter API是通过HTTPS进行的。

Ubuntu VM上的Python脚本无法连接到twitter API
