Ubuntu VM上的Python腳本無法連接到Twitter API

Question

我在Windows XP PC上使用帶有VitualBox的Ubuntu 12。我正在使用代理訪問互聯網。 我可以用Firefox瀏覽這些網站，以及下面的腳本：

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 

一切順利碼以上，但對於如下類似的代碼無法正常工作。

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) 

錯誤日誌如下。

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> 

請幫幫我。謝謝。

嘗試創建一個https處理程序，看看是否解決了這個問題。

改變這一行：

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

到

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

，並看看是否能工程，因爲你試圖訪問Twitter的API是通過HTTPS。
