需要有关此 Kombu 错误的帮助

Question

请原谅 python 解释器的复制和粘贴，但我正在尝试使用 Kombu，但我似乎无法创建消费者。请帮忙，我在这里完全陷入黑暗。

>>> 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。如果您使用的是rabbitmq，您可以使用 rabbitmqctl 命令来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')

这意味着队列已经被声明，但带有其他参数而不是您所指定的参数
现在就宣布这一点。
