示例1: test_subscribe_and_publish

# 需要导入模块: from Adafruit_IO import MQTTClient [as 别名]
# 或者: from Adafruit_IO.MQTTClient import subscribe [as 别名]
 def test_subscribe_and_publish(self):
     # Create MQTT test client.
     client = MQTTClient(self.get_test_username(), self.get_test_key())
     # Save all on_message handler responses.
     messages = []
     def on_message(mqtt_client, feed, payload):
         self.assertEqual(mqtt_client, client)
         messages.append((feed, payload))
     client.on_message = on_message
     # Connect and wait until on_connect event is fired.
     client.connect()
     self.wait_until_connected(client)
     # Subscribe to changes on a feed.
     client.subscribe('testfeed')
     # Publish a message on the feed.
     client.publish('testfeed', 42)
     # Wait for message to be received or timeout.
     start = time.time()
     while len(messages) == 0 and (time.time() - start) < TIMEOUT_SEC:
         client.loop()
         time.sleep(0)
     # Verify one update message with payload is received.
     self.assertListEqual(messages, [('testfeed', '42')])
