Question

我想获取队列中所有待处理的任务以保存在数据库中。并从队列中删除这些任务。

我知道channel.purgeQueue，但只会删除它们。

我需要知道队列中的待处理任务。

如何获取它们

Answer 1

这是RabbitMQ的基本功能，请阅读：

https://www.rabbitmq.com/tutorials/tutorial-two-python.html

您要查找的代码是：

Array
(
[0] => Array
    (
        [user_id] => 10
        [directors_count] => 6
    )

[1] => Array
    (
        [user_id] => 12
        [directors_count] => 5
    )

[2] => Array
    (
        [user_id] => 15
        [directors_count] => 2
    )

[3] => Array
    (
        [user_id] => 16
        [directors_count] => 1
    )

[4] => Array
    (
        [user_id] => 17


        [directors_count] => 0
        )

)

执行def callback(ch, method, properties, body): print " [x] Received %r" % (body,) ### PUT_YOUR_CODE_HERE print " [x] Done" ch.basic_ack(delivery_tag = method.delivery_tag) channel.basic_consume(callback, queue='hello')时，消息将从队列中删除
