概述
workerman/rabbitmq 是一个异步RabbitMQ客户端，使用AMQP协议。
RabbitMQ是一个基于AMQP（高级消息队列协议）实现的开源消息组件，它主要用于在分布式系统中存储和转发消息。RabbitMQ由高性能、高可用以及高扩展性出名的Erlang语言写成，具有高度的可靠性和可扩展性。它支持多种消息协议，包括AMQP、STOMP、MQTT等，并广泛应用于消息队列、消息中间件等领域。
RabbitMQ允许应用程序通过消息传递进行通信，这使得不同的应用程序可以在不同的语言和操作系统之间进行通信。
RabbitMQ的消息工作机制涉及消息从发送端到接收端的流转过程。在这个过程中，消息首先被发送到交换机（Exchange），然后交换机根据路由规则将消息路由到一个或多个队列（Queue）中。消费者（Consumer）从队列中获取消息并进行处理。
