摘要
目前基于HTTP的实时信息传输技术主要包括客户端定时器的同步刷新、基于AJAX的异步传输和服务器端Push这3种方法。提出了一种新型实时信息传输方法,该方法把基于AJAX的异步传输和服务器端Push两种技术结合起来,实现了利用HTTP长连接进行实时信息异步传输。最后给出了该方案在高校OA系统中的应用实例。
There are three transfer methods for real time information based on HTTP, which are synchronous refresh with client timer, asynchronous transmission based on AJAX and Server Push. A new transfer method for real time information is presented. This method combines asynchronous transmission based on AJAX and Server Push technology, to actualize real time information asynchronous transfer with HTTP persistent connection. An application of OA system in a university is presented with this new technology.
