基于web的推送技术在风险预警系统中的应用

Web-based push service applications in risk early warning system

为解决风险预警系统因传统web系统请求/响应模式而造成信息延迟的问题,本文提出了一种基于web服务器主动推送技术的风险预警系统的的方案,并阐述了此方案的关键技术以及具体实现。本风险预警方案通过使用基于HTTP长链接的Comet技术,具备了在web页面不重新刷新的情况下预警风险风险的能力。该系统一旦检测到风险,能够及时预警,因此,该系统满足设计需求,该方案是可行的。

In order to solve the risk early warning system for the request/response mode of traditional web system caused by the information delay problem, this paper proposes a risk warning system based on active web server push technology, and expounds the key technology of the scheme and implementation. The risk early warning scheme is based on the HTTP long link Comet technology, with the ability of risking early warning without refreshing the web page. Once the system detected the risk,can timely warning, so the system satisfies the design need, this plan is feasible.
