示例1: print

# 需要导入模块: from Adafruit_IO import MQTTClient [as 别名]
# 或者: from Adafruit_IO.MQTTClient import loop_blocking [as 别名]
    print('Subscribing to Feed {0}'.format(FEED_ID))
    client.subscribe(FEED_ID)
    print('Waiting for feed data...')

def disconnected(client):
    """Disconnected function will be called when the client disconnects."""
    sys.exit(1)

def message(client, feed_id, payload):
    """Message function will be called when a subscribed feed has a new value.
    The feed_id parameter identifies the feed, and the payload parameter has
    the new value.
    """
    print('Feed {0} received new value: {1}'.format(feed_id, payload))


# Create an MQTT client instance.
client = MQTTClient(ADAFRUIT_IO_USERNAME, ADAFRUIT_IO_KEY)

# Setup the callback functions defined above.
client.on_connect = connected
client.on_disconnect = disconnected
client.on_message = message

# Connect to the Adafruit IO server.
client.connect()

# The first option is to run a thread in the background so you can continue
# doing things in your program.
client.loop_blocking()
