如果想在on_message函数外部打印msg.payload,可以将msg.payload保存到一个变量中,然后在on_message函数外部打印该变量。具体代码如下: 代码语言:txt 复制 import paho.mqtt.client as mqtt # 定义回调函数 def on_message(client, userdata, msg): # 在回调函数内部处理消息 payload = msg.payload # 其他操...
defon_connect(client, userdata, flags, rc): # Subcribing to topic and recoonect for client.subscribe("data/gpsdata/server/#") print'subscribed to data/gpsdata/server/#' # Receive message defon_message(client, userdata, msg): # from kctsmarttransport.celery import bus_position_insert_task ...

(client, userdata, msg): print(f"Received...msg.payload.decode()}` from `{msg.topic}` topic") client.subscribe(topic) client.on_message = on_message...与 C ++ 或 Java 之类的高级语言不同,Python 比较适合设备侧的业务逻辑实现,使用 Python 您可以减少代码上的逻辑复杂度,降低与设备的交互成本...
