Python mqtt客户端，当没有互联网时试图连接到代理

Question

我家里的网络有点不稳定。我在raspberry pi上运行了pyhon代码，试图连接到＆＃34; test.mosquitto.com＆＃34;代理。

下面是我编写的python代码

import time
import paho.mqtt.client as mqtt
bConnected = False

def on_disconnect(client, userdata, msg):
    print "Disonnected from broker"
    global bConnected
    bConnected = False

def on_connect(client, userdata, msg):
    print "Connected to broker"
    global bConnected
    bConnected = True

def worker_thread():
    """Creates mqtt client which check connection between pi and mqtt broker"""
    client = mqtt.Client()
    client.on_disconnect = on_disconnect
    client.on_connect = on_connect
    global bConnected
    while not bConnected:
        try:
            print "Trying to connect broker"
            client.connect("test.mosquitto.org", 1883, 5)
            client.loop_forever()
            time.sleep(5)

        except:
            bConnected = False

对我来说很好。 请让我知道是否有另一种有效的方法。（我想应该有另一种方式）。 提前谢谢。
