需要有关此Kombu错误的帮助

Question

对不起，复制和粘贴python解释器，但我正在尝试使用Kombu，但我似乎不能创建消费者。请帮帮忙，我现在一无所知。

>>> from kombu.messaging import Consumer, Producer
>>> from kombu.entity import Exchange, Queue
>>> x = Exchange("stmt",type="topic")
>>> helloQ = Queue("hello", exchange=x, routing_key="stmt.hello")
>>>
>>> from kombu.connection import BrokerConnection
>>> conn = BrokerConnection("scheduledb.lab.compete.com", "clippy", "clippy", "clippy")
>>> channel = conn.channel()
>>> c = Consumer(channel, helloQ)

Answer 1

添加到@asksol的答案中。如果您正在使用rabbitmq，则可以使用rabbitmqctl命令列出队列详细信息，并将这些设置与您自己的代码中的设置进行比较。希望这能为您提供足够的信息来检测冲突。

Answer 2

查看错误

amqplib.client_0_8.exceptions.AMQPConnectionException: (530, u"NOT_ALLOWED - parameters for queue 'hello' in vhost 'clippy' not equivalent", (50, 10), 'Channel.queue_declare')

这意味着已经声明了队列，但是使用了其他参数，而不是现在声明它的参数。
