我是第一次使用Python和mosquitto库尝试MQTT . 我的客户端程序如下 . 我正在尝试在http://www.mqtt-dashboard.com/subscribe使用公共演示MQTT服务器 . 但是客户端代码失败，请参阅下面的错误 . 关于发生了什么的任何想法？
#!/usr/bin/env python
import mosquitto
client = mosquitto.Mosquitto("fredtest", clean_session=True)
client.connect("broker.mqttdashboard.com", 1883)
client.publish("fred.test", "hello world", 1)
client.loop_forever()
错误信息：
C:\tmp>python mqttclient.py
Traceback (most recent call last):

我目前无法将任何客户端连接到broker.mqttdashboard.com:1883 - 所以这可能不是您的代码的问题 .
要进行健全检查，您是否尝试连接到其他经纪人，例如iot.eclipse.org:1883？
