使用皮卡：
import pikapika_conn_params = pika.ConnectionParameters( host='localhost', port=5672, credentials=pika.credentials.PlainCredentials('guest', 'guest'),)connection = pika.BlockingConnection(pika_conn_params)channel = connection.channel()queue = channel.queue_declare( queue="your_queue", durable=True, exclusive=False, auto_delete=False)print(queue.method.message_count)使用PyRabbit：
from pyrabbit.api import Clientcl = Client('localhost:55672', 'guest', 'guest')cl.get_messages('example_vhost', 'example_queue')[0]['message_count']使用HTTP
句法：
curl -i -u user:password http://localhost:15672/api/queues/vhost/queue
例：
curl -i -u guest:guest http://localhost:15672/api/queues/%2f/celery
注意：默认虚拟主机是
/需要转义为
%2f
使用CLI：
$ sudo rabbitmqctl list_queues | grep 'my_queue'
