Odoo集成MQTT

1. 文件结构
   
2. MQTT 客户端

import paho.mqtt.client as mqtt

client_dict = {}
import logging

_logger = logging.getLogger(__name__)


class MQTTClient(object):
    def __init__(self, client_id, protocol, broker, port, username, password):
        self.client_id = client_id
        self.protocol = protocol
        self.broker = broker
        self.port = port
        self.username = username
        self.password = password
        self.client = mqtt.Client(client_id, protocol)
        self.client.username_pw_set(self.username, self.password)

    def connect(self, keepalive=60):
        self.client.connect(self.broker, self.port, keepalive)
        self.client.loop_start()

    def is_connected(self):
        return self.client.is_connected()

    def disconnect(self):
        self.client.disconnect()
        self.client.loop_stop()

    def subscribe(self, topic, qos):
        self.client.subscribe(topic, qos)

    def publish(self, topic, data, qos):
        _logger.debug(f"{topic}>>>>>>>>>>   发送消息      >>>>>>> {data}")
        self.client.publish(topic=topic, payload=data, qos=qos)

    def on_message(self, client, userdata, msg):
        print("收到消息：", msg.topic, msg.payload.decode()
