我試圖不斷聽取隊列後斷開了我，但經過一分鐘左右（假設我的隊列爲空）我斷開了與此錯誤：RabbitMQ的一段時間

這是我的代碼：

self._connect()
def _connect(self):
logger.info('Trying to connect to RabbitMQ')
while True:
try:
conn_broker = pika.BlockingConnection(
pika.ConnectionParameters(
host=conf.rabbit_server,
port=conf.rabbit_port,
virtual_host=conf.rabbit_vhost,
ssl=conf.rabbit_ssl, # do not set it to True if there is no ssl!
heartbeat_interval=conf.rabbit_heartbeat_interval,
credentials=pika.PlainCredentials(
conf.rabbit_user,
conf.rabbit_pass)))
logger.info('Successfully connected to Rabbit at %s:%s' % (conf.rabbit_server, conf.rabbit_port))
self.channel = conn_broker.channel()
# Don't dispatch a new message to a worker until it has processed and acknowledged the previous one
self.channel.basic_qos(prefetch_count=conf.rabbit_prefetch_count)
status = self.channel.queue_declare(queue=conf.rabbit_queue_name,
durable=conf.rabbit_queue_durable,

if status.method.message_count == 0:
logger.info("Queue empty")
else:
logger.info('Queue status: %s' % status)
self.channel.queue_bind(

exchange=conf.rabbit_exchange_name,
routing_key=conf.rabbit_exchange_routing_key)
except (pika.exceptions.AMQPConnectionError, pika.exceptions.AMQPChannelError), e:
time.sleep(3)
logger.error('Exception while connecting to Rabbit %s' %e)
else:
break
def get_channel(self):
return self.channel
我也有這個錯誤，這不是我想要的或期望的。我將嘗試輪詢隊列的同步版本，而不是basic_consume＆start_consuming成語。 – user2759991
