Question

是否可以直接从命令行查看RabbitMQ消息内容？

sudo rabbitmqctl list_queues 列出队列.

有没有命令命令sudo rabbitmqctl list_queue_messages queue_name？

Answer 1

您应该启用管理插件.

rabbitmq-plugins enable rabbitmq_management

看这里:

http://www.rabbitmq.com/plugins.html

这里是管理的具体细节.

http://www.rabbitmq.com/management.html

最后设置完成后,您需要按照以下说明安装和使用rabbitmqadmin工具.这可以用来与系统完全交互. http://www.rabbitmq.com/management-cli.html

例如:

rabbitmqadmin get queue=<QueueName> requeue=false

将为您提供队列中的第一条消息.

Answer 2

以下是我用来获取队列内容的命令:

使用https://www.rabbitmq.com/management-cli.html在Fedora linux上运行RabbitMQ 3.1.5版

这是我的交流:

eric@dev ~ $ sudo python rabbitmqadmin list exchanges
+-------+--------------------+---------+-------------+---------+----------+
| vhost |        name        |  type   | auto_delete | durable | internal |
+-------+--------------------+---------+-------------+---------+----------+
| /     |                    | direct  | False       | True    | False    |
| /     | kowalski           | topic   | False       | True    | False    |
+-------+--------------------+---------+-------------+---------+----------+

这是我的队列:

eric@dev ~ $ sudo python rabbitmqadmin list queues
+-------+----------+-------------+-----------+---------+------------------------+---------------------+--------+----------+----------------+-------------------------+---------------------+--------+---------+
| vhost |   name   | auto_delete | consumers | durable | exclusive_consumer_tag |     idle_since      | memory | messages | messages_ready | messages_unacknowledged |        node         | policy | status  |
+-------+----------+-------------+-----------+---------+------------------------+---------------------+--------+----------+----------------+-------------------------+---------------------+--------+---------+
| /     | myqueue  | False       | 0         | True    |                        | 2014-09-10 13:32:18 | 13760  | 0        | 0              | 0                       |rabbit@ip-11-1-52-125|        | running |
+-------+----------+-------------+-----------+---------+------------------------+---------------------+--------+----------+----------------+-------------------------+---------------------+--------+---------+

将一些物品塞进myqueue:

curl -i -u guest:guest http://localhost:15672/api/exchanges/%2f/kowalski/publish -d '{"properties":{},"routing_key":"abcxyz","payload":"foobar","payload_encoding":"string"}'
HTTP/1.1 200 OK
Server: MochiWeb/1.1 WebMachine/1.10.0 (never breaks eye contact)
Date: Wed, 10 Sep 2014 17:46:59 GMT
content-type: application/json
Content-Length: 15
Cache-Control: no-cache

{"routed":true}

RabbitMQ查看队列中的消息:

eric@dev ~ $ sudo python rabbitmqadmin get queue=myqueue requeue=true count=10
+-------------+----------+---------------+---------------------------------------+---------------+------------------+------------+-------------+
| routing_key | exchange | message_count |                        payload        | payload_bytes | payload_encoding | properties | redelivered |
+-------------+----------+---------------+---------------------------------------+---------------+------------------+------------+-------------+
| abcxyz      | kowalski | 10            | foobar                                | 6             | string           |            | True        |
| abcxyz      | kowalski | 9             | {'testdata':'test'}                   | 19            | string           |            | True        |
| abcxyz      | kowalski | 8             | {'mykey':'myvalue'}                   | 19            | string           |            | True        |
| abcxyz      | kowalski | 7             | {'mykey':'myvalue'}                   | 19            | string           |            | True        |
+-------------+----------+---------------+---------------------------------------+---------------+------------------+------------+-------------+

Answer 3

我编写了rabbitmq-dump-queue,它允许将来自RabbitMQ队列的消息转储到本地文件,并按原始顺序重新排列消息.

示例用法(转储队列的前50条消息incoming_1):

rabbitmq-dump-queue -url="amqp://user:password@rabbitmq.example.com:5672/" -queue=incoming_1 -max-messages=50 -output-dir=/tmp

Answer 4

您可以使用RabbitMQ API来获取计数或消息:

/api/queues/vhost/name/get

从队列中获取消息.(这不是HTTP GET,因为它会改变队列的状态.)你应该发布一个看起来像的身体:

{"count":5,"requeue":true,"encoding":"auto","truncate":50000}

count控制要获取的最大消息数.如果队列无法立即提供,则可能会收到比此更少的消息.

requeue确定是否将从队列中删除消息.如果requeue为true,它们将被重新排队 - 但是它们的redelivered标志将被设置.encoding必须是"auto"(在这种情况下,如果有效负载将是有效的UTF-8,则返回为字符串,否则为base64编码)或"base64"(在这种情况下,有效负载将始终为base64编码).如果存在truncate,它将截断消息有效负载,如果它大于给定的大小(以字节为单位).truncate是可选的; 所有其他密钥是强制性的.

请注意,HTTP API中的发布/获取路径用于注入测试消息,诊断等 - 它们不实现可靠的传递,因此应被视为sysadmin的工具,而不是用于消息传递的通用API.

Answer 5

如果你想要一个队列中的多条消息，比如说 10 条消息，使用的命令是：

rabbitmqadmin get queue=<QueueName> ackmode=ack_requeue_true count=10

如果您不希望消息重新排队，只需更改ackmode为ack_requeue_false.

Answer 6

有点晚了，但是rabbitmq有一个内置的跟踪器，允许您在日志中查看传入的消息。启用后，您可以tail -f /var/tmp/rabbitmq-tracing/.log（在 mac 上）观看消息。
