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')])
