Tried to perform REST GET through python requests with the following code and I got error.

Code snip:

import requests
header = {'Authorization': 'Bearer...'}
url = az_base_url + az_subscription_id + '/resourcegroups/Default-Networking/resources?' + az_api_version
r = requests.get(url, headers=header)

Error:

/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/util/ssl_.py:79: 
          InsecurePlatformWarning: A true SSLContext object is not available. 
          This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. 
          For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning

My python version is 2.7.3. I tried to install urllib3 and requests[security] as some other thread suggests, I still got the same error.

Wonder if anyone can provide some tips?

The docs give a fair indicator of what's required., however requests allow us to skip a few steps:

You only need to install the security package extras (thanks @admdrew for pointing it out)

$ pip install requests[security]

or, install them directly:

$ pip install pyopenssl ndg-httpsclient pyasn1

Requests will then automatically inject pyopenssl into urllib3

If you're on ubuntu, you may run into trouble installing pyopenssl, you'll need these dependencies:

$ apt-get install libffi-dev libssl-dev
