回执消息-队列模式

简介

当您使用隐私号码服务绑定一组AXB(或者AXN、以下统一以AXB为代表说明)隐私关系后，可以通过使用MNS的Queue模型来接收话单回执消息，话单回执消息时记录了AXB三元组发生的所有的通话记录行为。

消息的订阅

云通信的所有业务消息都用过MNS消息服务向外发送。用户每订阅一个类别的消息(比如隐私号码话单回执消息(SecretReport)，系统都会为用户分配一个独立的消息队列。用户可以通过阿里云账号拿到一个临时的token用于获取队列中的消息。用户可以下载demo，编写简单的消息处理类即可完成消息处理的任务。在页面上订阅消息，订阅完消息后，能拿到消息队列名称(queueName)。比如：Alicom-Queue-xxxxxx-SecretReport 。队列名字每个用户都不同。

下载消息SDK

下载对应语音的消息DEMO工程,工程所需要的所有依赖jar包都放在DEMO工程的lib目录下，将对于的jar包引入到您的工程当中既可按照DEMO样例编写接收消息的程序。
