Create HTTP proxy environment using docker
Project description
This is a python module that starts a Squid proxy running in a docker container, and sets up an environment for using this proxy to handle HTTP(S) requests both from python code and external programs. The purpose is mainly for testing proxy support in code that needs to make HTTP(S) requests. The proxy supports both HTTP and HTTPS, and Basic proxy authorization.
Using an existing HTTP proxy
If a proxy is already set in the http_proxy environment variable, the newly created squid proxy will still work by using the existing proxy as “cache peer”. If you don’t want this, delete http_proxy from the environment before starting the temporary proxy.
Usage
from proxyenv.proxyenv import ProxyFactory
proxyfact=ProxyFactory()
# Example for using urllib
from six.moves.urllib import request
with proxyfact() as proxy:
opener = request.build_opener(proxy.get_handler)
opener.open(url)
# Example for starting external program with proxy-related environment
# variables
from subprocess import check_output
with proxyfact(user="johndoe:secret", port=3077) as proxy:
check_output(["/usr/bin/wget", url])
Please use the main program in proxyenv/proxyenv.py as additional source of documentation.
