预先感谢您提供的任何帮助。
我在安装了 python 2.7 的 ubuntu 12.10 上。我根据其他帖子编写了一个简单的脚本来测试 http 和 https 连接:
import urllib2, urllib
def set_proxy():
proxy = urllib2.ProxyHandler({'http': 'http://<proxyhost>:<proxyport>'})
opener = urllib2.build_opener(proxy, urllib2.HTTPHandler)
urllib2.install_opener(opener)
def http_call():
conn = urllib2.urlopen('http://www.whatismyip.com/')
return conn.read()
def https_call():
conn = urllib2.urlopen('https://chase.com/')
return conn.read()
set_proxy()
webpage = open('webpage.html', 'w')
return_str = https_call()
webpage.write(return_str)
webpage.close()
print ("check for output in webpage.html")
使用 http 的测试工作正常,但使用 https 会产生以下输出:
Traceback (most recent call last):
File "test.py", line 18, in <module>
return_str = https_call()
File "test.py", line 13, in https_call
conn = urllib2.urlopen('https://chase.com/')
File "/usr/lib/python2.7/urllib2.py", line 127, in urlopen
return _opener.open(url, data, timeout)
File "/usr/lib/python2.7/urllib2.py", line 401, in open
response = self._open(req, data)
File "/usr/lib/python2.7/urllib2.py", line 419, in _open
'_open', req)
File "/usr/lib/python2.7/urllib2.py", line 379, in _call_chain
result = func(*args)
File "/usr/lib/python2.7/urllib2.py", line 1219, in https_open
return self.do_open(httplib.HTTPSConnection, req)
File "/usr/lib/python2.7/urllib2.py", line 1181, in do_open
raise URLError(err)
urllib2.URLError: <urlopen error [Errno 110] Connection timed out>
这是我的设置:
root@sc11137376:/usr/local/pythonbrew# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.10
Release: 12.10
Codename: quantal
root@sc11137376:/usr/local/pythonbrew# python --version
Python 2.7.3
root@sc11137376:/usr/local/pythonbrew# openssl version
OpenSSL 1.0.1c 10 May 2012
我在类似的较早的帖子中看到了从安装了 openssl 的源代码重建 python 的建议。我希望有一个不同的解决方案来解决我的问题,因为这是更新的 ubuntu/python 版本,并且 openssl 已经在系统上。
任何指针表示赞赏。
注意:在环境中设置 HTTPS_PROXY 会将错误消息更改为以下内容(从错误号 110 到 113):
urllib2.URLError: <urlopen error [Errno 113] No route to host>
顺便说一句,以下也失败了:
root@sc11137376:/usr/local/pythonbrew# openssl s_client -connect encrypted.google.com:443
connect: No route to host
connect:errno=113
不确定我是否可以做任何事情来解决这个问题。
