Suppress InsecureRequestWarning: Unverified HTTPS request is being made in Python2.6

Question

I am writing scripts in Python2.6 with use of pyVmomi and while using one of the connection methods:

service_instance = connect.SmartConnect(host=args.ip,
                                        user=args.user,
                                        pwd=args.password)

I get the following warning:

/usr/lib/python2.6/site-packages/requests/packages/urllib3/connectionpool.py:734: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.org/en/latest/security.html
  InsecureRequestWarning)

What's interesting is that I do not have urllib3 installed with pip (but it's there in /usr/lib/python2.6/site-packages/requests/packages/urllib3/).

I have tried as suggested here

import urllib3
...
urllib3.disable_warnings()

but that didn't change anything.

Answer 1

You can disable any Python warnings via the PYTHONWARNINGS environment variable. In this case, you want:

export PYTHONWARNINGS="ignore:Unverified HTTPS request"

To disable using Python code (requests >= 2.16.0):

import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

For requests < 2.16.0, see original answer below.

Original answer

The reason doing urllib3.disable_warnings() didn't work for you is because it looks like you're using a separate instance of urllib3 vendored inside of requests.

I gather this based on the path here: /usr/lib/python2.6/site-packages/requests/packages/urllib3/connectionpool.py

To disable warnings in requests' vendored urllib3, you'll need to import that specific instance of the module:

import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning

requests.packages.urllib3.disable_warnings(InsecureRequestWarning)

Answer 2

This is the answer in 2017. urllib3 not a part of requests anymore

import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

Answer 3

Per this github comment, one can disable urllib3 request warnings via requests in a 1-liner:

requests.packages.urllib3.disable_warnings()

This will suppress all warnings though, not just InsecureRequest (ie it will also suppress InsecurePlatform etc). In cases where we just want stuff to work, I find the conciseness handy.
