Question

试图找出与RabbitMQ的连接不断下降的原因。我正在使用阻塞连接和生成器来持续处理消息。

连接看起来像：

connection = pika.BlockingConnection(pika.ConnectionParameters(host=HOST, heartbeat_interval=0))

发电机是：

for method, properties, body in channel.consume(QUEUE_NAME)

使用heartbeat_interval=0将心跳设置为关闭。我只创建一个连接，当我想要发回消息时创建一个新的频道。鼠兔的失败似乎来自承认：

Traceback (most recent call last):
  File "everlast_generator.py", line 101, in <module>
    channel.basic_ack(delivery_tag = method.delivery_tag)
  File "/usr/local/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line 1909, in basic_ack
    self._impl.basic_ack(delivery_tag=delivery_tag, multiple=multiple)
  File "/usr/local/lib/python2.7/dist-packages/pika/channel.py", line 159, in basic_ack
    raise exceptions.ChannelClosed()
ChannelClosed

代码如下：

connection = pika.BlockingConnection(pika.ConnectionParameters(host=HOST, heartbeat_interval=0))
channel = connection.channel()
for method, properties, body in channel.consume(QUEUE_NAME):
    ### do some work ###
    ### do some more work on inbound message ###
    result = some_function()

    if result is not None:  
        try:    
            channel.basic_ack(delivery_tag = method.delivery_tag)
            response_channel(result, connection) # send back a response on a different queue!
        except Exception as e:
            LOGGING.info('Failed', e)
            print 'Failed'
            print traceback.print_exception(exc_type, exc_value, exc_traceback, limit=6)
            LOGGING.exception("Failed...")

我附上了RabbitMQ日志：
