带有 SOCKS 代理的 Python paho.mqtt

Question

My organisation has an enterprise FW and a SOCKS proxy to allow bypassing it. I need to be able to use MQTT with an external server. I am able to use PySocks in a python script (to monkey patch) but when I try using paho.mqtt it breaks.

Is there an MQTT lib that allowes using SOCKS? Is there another way for to go at it?

#!/usr/bin/python
import socket
import socks
import paho.mqtt.client as mqtt
socks.set_default_proxy(socks.SOCKS5,"my-proxy",1080)
socket.socket = socks.socksocket

def on_connect(client, userdata, flags, rc):
    print("Connected with result code "+str(rc))
client.subscribe("$SYS/#")
def on_message(client, userdata, msg):
    print(msg.topic+" "+str(msg.payload))
client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
client.connect("iot.eclipse.org", 1883, 60)
client.loop_forever()

error:

I think paho python has socks support now as mentioned in the Github url:

paho python setup.py extras

Please look at proxy_set method in client.py
