我想certification validation在使用内部企业链接向服务器发出请求时忽略它.

使用python requests库我会这样做:

r = requests.get(link, allow_redirects=False,verify=False)

如何使用urllib2库进行相同的操作？

这项工作很好:

import urllib2

opener = urllib2.build_opener(
                urllib2.HTTPHandler(),
                urllib2.HTTPSHandler(),
                urllib2.ProxyHandler({'http': 'http://user:pass@proxy:3128'}))
urllib2.install_opener(opener)
print urllib2.urlopen('http://www.google.com').read()

但是,如果http更改为https:

...
print urllib2.urlopen('https://www.google.com').read()

有错误:

Traceback (most recent call last):
  File "D:\Temp\6\tmp.py", line 13, in <module>
    print urllib2.urlopen('https://www.google.com').read()
  File "C:\Python26\lib\urllib2.py", line 124, in urlopen
    return _opener.open(url, data, timeout)
  File "C:\Python26\lib\urllib2.py", line 389, in open
    response = self._open(req, data)
  File "C:\Python26\lib\urllib2.py", line 407, in _open
    '_open', req)
  File "C:\Python26\lib\urllib2.py", line 367, in _call_chain
    result = func(*args)
  File "C:\Python26\lib\urllib2.py", line 1154, in https_open
    return self.do_open(httplib.HTTPSConnection, …

我使用代理集作为环境变量(export http_proxy = example.com).对于使用urllib2的一个调用,我需要暂时禁用它,即.取消设置http_proxy.我已经尝试了文档和互联网中建议的各种方法,但到目前为止一直无法取消代理.到目前为止,我尝试过:

# doesn't work
req = urllib2.Request('http://www.google.com')
req.set_proxy(None,None)
urllib2.urlopen(req)

# also doesn't work
urllib.getproxies = lambda x = None: {}
