How to use requests library without system-configured proxies

问题

If I supply None or an empty dict to the proxies parameter, requests will automatically fall back to the proxies configured for the operating system as obtained through urllib.request.getproxies() (Python 3) / urllib.getproxies().

import requests
r = requests.get('http://google.com', proxies = {}) # or = None...
print(r.text)

Specifying proxies = { 'http': False } will even cause requests to hang completely for whatever weird reason.

So how do I direct requests to perform HTTP requests directly, without any proxy ?

回答1:

Turns out you have to use an empty string for the protocol you want to use a direct connection:

r = requests.get('http://google.com', proxies = { 'http': '', ... })

Weird, but that's life.
