来自PHP的同步AMQP [英] Synchronous AMQP from PHP
问题描述
PHP是否可以将AMQP视为RPC服务，并发送消息并阻塞直到返回答复?有没有很好的例子，是否有任何库都以易于使用的方式包装了这些功能?
Can PHP treat AMQP like an RPC service, and send a message and block until a reply is returned? Are there any good examples of this, and do any libraries wrap such functionality up in an easy-to-use way?
我希望具有代理消息传递系统的灵活性，但可以保护Web层免于需要了解其异步特性.
I'd like to have the flexibility of a brokered messaging system, but shield the web tier from needing to know about its asynchronous nature.
推荐答案
当然可以.查看RPC样式的请求如何在系统中流动:
Sure, absolutely. Look at how an RPC-style request flows around a system:
- 发出请求
- 请求者现在阻止等待对该请求的答复
这完全可以通过AMQP之类的异步消息系统实现.您只需要自己进行RPC关联:
That's completely implementable with an asynchronous message system like AMQP. You just need to do the RPC correlation yourself:
- 在其中具有唯一ID的异步消息中发送您的请求(这不会阻止)
- 从消息传递系统接收消息并阻止，直到您收到具有相同唯一ID的消息(这意味着您刚刚收到了回复)
RabbitMQ 是AMQP经纪人，提供
RabbitMQ, an AMQP broker, offers documentation online on how to do exactly this.
