云环境下实时消息推送服务构建研究

Research on Construction of Real-time Push Service in Cloud Environment

随着移动互联网技术的发展,各类消息纵横交错,人们在获取关联信息时常感到无从选择。传统的消息获取,用户需要主动拉取网络存储的消息,此种方式获取消息的效率极其低下,会产生众多与用户无关的消息。消息推送需要用户不停地拉取刷新,属于被动推送。随着云技术的发展,消息推送技术逐步转变为云推送,告别了单一服务器推送的模式。对现有各类消息推送技术进行研究和分析,针对传统基于主题订阅模式的消息推送服务只能对应单一移动端通信的不足,提出了云实验环境下实现实时消息推送服务的构建方案,设计了消息推送服务(PushWeb)的运行框架,运用H5技术中的WebSocket技术实现了管理平台和移动客户端应用程序,并将其部署在阿里云中,经测试在良好的网络环境下能够将消息实时准确地推送至移动端。

With the development of mobile Internet technology,various kinds of notification are intermingled so that people are often at a loss on how to acquire related notification.As for traditional notification acquisition,users need to actively search notification stored online.This way of notification acquisition is extremely inefficient,and a large number of notifications unrelated to users will emerge.Notification push needs users to constantly pull and refresh notifications,so it belongs to passive push.As cloud technology advances,notification push technology has gradually evolved into cloud push and thus making the model of single server push outdated.On the basis of analysis and research on present notification push technology,the shortcoming that the traditional push service based on topic subscription can only work in single mobile communication terminal is found,targeted at which a solution of realizing real-time notification push service in cloud experimental environment is proposed,and the experiment framework of notification push service(PushWeb)is designed.Besides,management of platform and mobile client applications is realized by means of the WebSocket technology in H5,which is deployed in Alibaba Cloud.After inspection and testing,notifications can be correctly pushed to mobile terminals in real-time in fine network environment.
