Let user specify HTTP proxy port about python-slack-sdk

[simisimis]

would be nice if that would be added as I am not able to use slackclient from hosts behind proxy

[aaronhackney]

This was solved in https://github.com/slackapi/python-slackclient version 1.06.
I have posted a small write up of using the proxy feature here with a short explanation of how it works.

I have slackclient working from behind a proxy by setting the HTTP_PROXY and HTTP_PROXY environment variables.

If someone needs it quick and dirty, here my solution. (Setting the HTTP_PROXY and HTTP_PROXY don't work for me.)

import requests
import websocket
import copy


#patch requests and websockets to have a fixed proxy
old_post = copy.deepcopy(requests.post)
def new_post(url, data=None, json=None, proxies = {"http": "http://proxy:1234", "https": "https://proxy:1234"}, **kwargs):
    kwargs["proxies"] = proxies
    return old_post(url, data, json, **kwargs)

requests.post = new_post

old_create_connection = copy.deepcopy(websocket.create_connection)
def new_create_connection(url, timeout=None, class_=websocket.WebSocket, http_proxy_host="proxy", http_proxy_port=1234, **options):
    options["http_proxy_host"] = http_proxy_host
    options["http_proxy_port"] = http_proxy_port
    return old_create_connection(url, timeout, class_, **options)

websocket.create_connection = new_create_connection

from slackclient import SlackClient
