问题
在python中使用paho.mqtt时on_message中的msg.payload返回参数为16进制混合ascii码的格式,想输出纯16进制的报文,麻烦帮忙看一下
import time
import paho.mqtt.client as mqtt
# The callback for when the client receives a CONNACK response from the server.
def on_connect(client, userdata, flags, rc):
if rc == 0:
print("连接成功")
print("Connected with result code " + str(rc))
def on_message(client, userdata, msg):
mm = str(msg.payload).split("'")
missige = mm[1]
nowTime = time.strftime("%Y-%m-%d %H:%M:%S")
print(msg.topic + " " + str(msg.payload))
print(nowTime + missige)
# print(f"Received `{msg.payload.decode()}` from `{msg.topic}` topic")
client = mqtt.Client(protocol=3)
client.username_pw_set("admin", "password")
client.on_connect = on_connect
client.on_message = on_message
client.connect(host="192.168.1.101", port = 1883, keepalive=60) # 订阅频道
time.sleep(1)
# client.subscribe("public")
client.subscribe([("#", 0), ("test", 2)])
client.loop_forever()
