图文直播系统中的AJAX引擎设计

Design on AJAX Engine in Text & Photos Broadcast System

采用了以XML为通信交换的数据格式,并运用TEA加密算法进行数据加密,构建了一个数据异步传输的AJAX引擎。并以四川广播电视大学三十周年校庆图文直播系统为背景,将AJAX引擎应用于直播开发的异步通信中,很好解决了浏览器阻塞问题。实践表明,采用AJAX引擎方式与传统B/S同步方式相比,具有图片刷新快、无页面闪烁的特点。

This paper make detail discussion on constructing a data transmission of asynchronous AJAX engine which based on XML data exchange,and used the encrypting arithmetic of TEA.Combining with 30th anniversary textphotos broadcast system of Scrtvu,we apply AJAX engine method to realize the browser and live Servers with asynchronous communication,and well solved the obstruction bwtween them.Compared with traditional B/S synchronous mode,adopting AJAX method has picture refurbishing quickly and non-page twinkle characteristic in practice.
