这就是我所拥有的：
将消息注入AWS SQS队列的CI控制器(感谢[url = http://codeigniter.com/forums/member/196201/]coccodrillo[/url]提供有关如何将AWS SDK集成到CI中的优秀说明.请参见此处：Integrating AWS SDK as a library in Codeigniter).

一个CI控制器,它接收队列中的消息并将其写入日志文件,然后删除队列中的消息.

我想有一个CI守护进程,它将监听这个队列,当它们在那里时接收消息并对该消息做一些有用的事情,然后删除该消息.所以我从System_Daemon文档中的示例开始,并在接收程序的CI代码中添加.见下面的代码

这是正确的做法吗？你能指导我做“正确的方式”吗？我已经把各种知识渊博的论坛搞得一团糟了……请帮帮我吧！
