Problem urllib2 with HTTPS

Navigation
3

I'm trying to retrieve a page on Flickr using urllib2 and I get the following error when I execute the command urllib2.urlopen('https://www.flickr.com') 

File "/usr/lib/python2.7/urllib2.py", line 104, in urlopen
    return _opener.open(url, data, timeout)   
File "/usr/lib/python2.7/urllib2.py", line 361, in open
    response = self._open(req, data)   
File "/usr/lib/python2.7/urllib2.py", line 379, in _open
    '_open', req)   
File "/usr/lib/python2.7/urllib2.py", line 339, in _call_chain
    result = func(*args)   
File "/usr/lib/python2.7/urllib2.py", line 1099, in https_open
    return self.do_open(httplib.HTTPSConnection, req)   
File "/usr/lib/python2.7/urllib2.py", line 1066, in do_open
    raise URLError(err) urllib2.URLError: <urlopen error [Errno 111] Connection refused>

Apparently the problem occurs when I connect with HTTPS because with HTTP it works. FLickr uses TLS 1.2. I do not know if it's a version or SSL problem.

Does anyone know? I need to connect through HTTPS. Thanks

Surely you will have to specify the SSL protocol that you want to use. It can be passed as context to urllib2.urlopen : 

import ssl
import urllib2

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
req = urllib2.urlopen('https://www.flickr.com', context=context)

Edited

Also make sure you are using the latest revision of python-2.7 (minimum python-2.7.9). The python2 SSL library has serious security flaws and only the latest patches receive the patches created from python3.

Simply ping link to try not to have problems opening the url, if you are under a proxy server the problem is probably because it prevents you from accessing, or you're offline.

deal with this way: 

import urllib2

req = urllib2.Request('https://www.flickr.com')
response = urllib2.urlopen(req)
contenido = response.read()
print contenido
