我的Kombu创建了一个奇怪的问题队列。过了一段时间,他们就停止收到消息。没有错误,但不再收到消息。当我取消绑定队列(从rabbitmq web界面)并将其重新绑定到相同的交换和路由键时,一切都在重新运行一段时间......然后再次。
我在这里错过了什么?我很乐意为此提供帮助。 我想也许我应该添加心跳?别的什么?
这是侦听器用来创建队列并监听它的类:
class UpdaterMixin(object):
# binding management commands to event names
# override in subclass
event_handlers = {}
app_name = '' #override in subclass
def __init__(self):
if not self.app_name or len(self.event_handlers) == 0:
print('app_name or event_handlers arent implemented')
raise NotImplementedError()
else:
self.connection_url = settings.BROKER_URL
self.exchange_name = settings.BUS_SETTINGS['exchange_name']
self.exchange_type = settings.BUS_SETTINGS['exchange_type']
self.routing_key = settings.ROUTING_KEYS[self.app_name]
def start_listener(self):
logger.info('started %s updater listener' % self.app_name)\\
with Connection(self.connection_url) as connection:
exchange = Exchange(self.exchange_name, self.exchange_type, durable=True)
queue = Queue('%s_updater' % self.app_name, exchange=exchange, routing_key=self.routing_key)
with connection.Consumer(queue, callbacks=[self.process_message]) as consumer:
while True:
logger.info('Consuming events')
connection.drain_events()
def process_message(self, body, message):
logger.info('data received: %s' % body)
handler = self.event_handlers[body['event']]
logger.info('Executing management command: %s' % str(handler))
handler(body)
message.ack()
