基于WebSocket的实时通信机制的设计与实现

Design and Implementation of Real-time Communication Mechanism Based on WebSocket

随着信息的高度发达,人类对于信息时效性的要求越来越高,Web通信作为获取信息的重要方式,通过HTTP协议已经难以满足Web应用日益复杂的需求了。近年来,随着HTML5的诞生,WebSocket协议被提出,它实现了浏览器与服务器的全双工通信,扩展了浏览器与服务端的通信功能,使服务端也能主动向客户端发送数据。论文介绍了基于WebSocket协议的实时通信机制以及相对于传统方案的优势,并结合安全加密机制实现一种安全实时Web应用。

With the highly developed information,the demand for information timeliness is getting higher and higher,Web communication is as an important way to obtain information,through the HTTP protocol has been difficult to meet the increasingly complex needs of Web app.In recent years,with the birth of HTML5,WebSocket protocol is proposed,it implements the browser and server full-duplex communication,the communication function of browser and server-side is extended,so that the server can also take the initiative to send data to the client.This paper introduces the real-time communication mechanism based on WebSocket protocol and the advantages compared with the traditional scheme,and combines security encryption mechanism to realize a secure real-time Web application.
