How do I have python httplib accept untrusted certs?

How do I have python httplib accept untrusted certs? I created a snake oil/self signed cert on my webserver, and my python client fails to connect as I am using a untrusted cert.

I'd rather problematically fix this in my client code rather than have it trusted on my system.

import httplib


def main():
    conn = httplib.HTTPSConnection("127.0.0.1:443")
    conn.request("HEAD","/")
    res = conn.getresponse()
    print res.status, res.reason
    data = res.read()
    print len(data)


if __name__ == "__main__":
    main()

Some of my scripts stopped working after updating my computer. Turns out, this was the problem: https://docs.python.org/2/library/httplib.html#httplib.HTTPSConnection

Changed in version 2.7.9: context was added.

This class now performs all the necessary certificate and hostname checks by default. To revert to the previous, unverified, behavior ssl._create_unverified_context() can be passed to the context parameter.

So if your version of Python is >= 2.7.9 (2.7.10 in my case), you'll likely run into this. To fix it, I updated my call:

httplib.HTTPSConnection(hostname, timeout=5, context=ssl._create_unverified_context())

This is likely the simplest change to retain the same behavior.
