Python: use httplib with proxy authentication

httplib_proxy.py

import urlparse
import httplib
import base64

proxy_uri = "http://user:password@proxy_host:proxy_port"
host = 'www.google.com'
port = 443

url = urlparse.urlparse(proxy_uri)
conn = httplib.HTTPSConnection(url.hostname, url.port)
headers = {}
if url.username and url.password:
    auth = '%s:%s' % (url.username, url.password)
    headers['Proxy-Authorization'] = 'Basic ' + base64.b64encode(auth)

conn.set_tunnel(host, port, headers)
conn.request("GET", "/")
response = conn.getresponse()
print response.status, response.reason
output = response.read()

This worked for me for Python 3:
headers['Proxy-Authorization'] = 'Basic ' + str(base64.b64encode(auth.encode()))

This worked for me for Python 3:
headers['Proxy-Authorization'] = 'Basic ' + str(base64.b64encode(auth.encode())).replace("b'", "").replace("'", "")

Hello. Im trying to do this.what is want to understand is where exactly do we specify the actual password to use for authentication. I understand that this connection is done via SSL and that we use base64 encryption but where in the code is the username and password going ro be inserted. Sorry for the ignorance. Thank you.

@victoos22 You need to edit the first line, proxy_uri = "http://user:password@proxy_host:proxy_port", and replace the user:password with your user/password for your proxy.

how do you authenticate the host if a basic authentication is required - i.e if it requires a username and password to have access to the API service

Apparently, when I run the conn.request(), it times out. This shouldn't be happening. Anyone ever encountered this?

It's still working when I pass the wrong URL password. Shouldn't it give an Authentication exception?
