requests: how to disable / bypass proxy

The only way I’m currently aware of for disabling proxies entirely is the following:

• Create a session
• Set session.trust_env to False
• Create your request using that session

import requests

session = requests.Session()
session.trust_env = False

response = session.get('http://www.stackoverflow.com')

This is based on this comment by Lukasa and the (limited) documentation for requests.Session.trust_env.

Note: Setting trust_env to False also ignores the following:

• Authentication information from .netrc (code)
• CA bundles defined in REQUESTS_CA_BUNDLE or CURL_CA_BUNDLE (code)

If however you only want to disable proxies for a particular domain (like localhost), you can use the NO_PROXY environment variable:

import os
import requests

os.environ['NO_PROXY'] = 'stackoverflow.com'

response = requests.get('http://www.stackoverflow.com')
