MQTT Web Socket in python

Question

So, I'm trying to connect with this code but this paho library does not work for it.

 import sys
 import paho.mqtt.client as mqtt

 def on_connect(mqttc, obj, flags, rc):
     print("rc: "+str(rc))

 def on_message(mqttc, obj, msg):
     print(msg.topic+" "+str(msg.qos)+" "+str(msg.payload))

 def on_publish(mqttc, obj, mid):
     print("mid: "+str(mid))

 def on_subscribe(mqttc, obj, mid, granted_qos):
     print("Subscribed: "+str(mid)+" "+str(granted_qos))

 def on_log(mqttc, obj, level, string):
     print(string)

 mqttc = mqtt.Client()   
 mqttc.on_message = on_message
 mqttc.on_connect = on_connect
 mqttc.on_publish = on_publish
 mqttc.on_subscribe = on_subscribe
 mqttc.connect("test.mosquitto.org", 8080, 60)
 mqttc.subscribe("test/iot", 0)

 mqttc.loop_forever()

Is there support in python to subscribe to the MQTT broker with port 8080?

Answer 1

You can simply create a configuration file for example in

/etc/mosquitto/mosquitto.conf

with the following contents:

listener 1883
protocol mqtt

listener 9001
protocol websockets

then run mosquito with the following

mosquitto -c /etc/mosquitto/mosquitto.conf

You should get this output:

1469015320: mosquitto version 1.4.8 (build date 2016-05-3112:07:40+0200) starting
1469015320: Config loaded from /etc/mosquitto/mosquitto1.conf.
1469015320: Opening ipv4 listen socket on port 1883.
1469015320: Opening ipv6 listen socket on port 1883.
1469015320: Opening websockets listen socket on port 9001.

Your python client then connects to port 1883 and the browser client to 9001
