摘  要
HTML5是下一代互联网的Web标准，和以前的版本不同，HTML5并非仅仅用来表示Web 内容，它将使Web 进入一个成熟的应用平台，在这个平台上，视频、音频、图像和动画，以及同电脑的交互都被标准化。随着Adobe宣布停止Flash移动版开发，不少人预言HTML5的发展将给移动互联网产业带来革命性的深刻变化。作为新一代的网页语言，HTML5跨平台的支持得到不断增强，智能手机的迅速普及加上资费和网络速度的逐渐松绑，也为HTML5技术提供了良好的发展环境。
这其中有“Web 的 TCP”之称的 WebSocket 格外吸引开发人员的注意。WebSocket 的出现使得浏览器提供对 Socket 的支持成为可能，从而在浏览器和服务器之间提供了一个基于 TCP 连接的双向通道。Web 开发人员可以非常方便地使用 WebSocket 构建实时 Web 应用，开发人员的手中从此又多了一柄神兵利器。
本文首先分析国内外研究现状，然后介绍本文用到的关键技术的介绍以及本文实例开发中的环境配置的方法，接下来会详细说明如何利用WebSocket技术实现一个简单的室，并对当中遇到的问题进行分析与解决。
本文的创新点是利用最热门的HTML5技术WebSocket结合C#的后台实现做一个简单的聊天室，从而更加清晰地阐述HTML5的优缺点，并且提出一些应该注意的问题和解决方法，以给后来者一些经验和教训。

ABSTRACT
HTML5 is the next generation of Internet Web standards, and com in contrast with the previous version, HTML5 is not only used to represent Web content, it will enable the Web into a full-fledged application platform, in this platform, video, audio, images and animations, as well as interaction with the computer are standardized. As Adobe announced the end to support the Flash mobile version of the development, many people predicted the development of HTML5 mobile Internet industry will bring profound changes in the revolutionary. As a new generation of web language, HTML5 cross-platform support has been growing, the rapid adoption of smart phone plus tariff and network speed gradually relaxed, and also provides a good environment for the development of HTML5 te
chnology.
The WebSocket步数在哪里打开 which said of the Web's TCP is especially attractive to the attention of developers. The WebSocket appear the browser support for Socket possible, thus a two-way channel based on the TCP connection between the browser and the server. Web developers can very easily use the WebSocket to build real-time Web applications, in the hands of developers from the addition of a two-edged magic weapon.
First of all, I describes the configuration of the environment in the introduction of key technologies used in this article, as well as examples of the development of this article, the next will explain in detail how to use the WebSocket technologya simple online chat rooms, and among the problems encountered in the analysis and solution.
The innovation of this paper is the use of the most popular HTML5 technology behind the scenes to make a simple chat room WebSocket combination of C #, in order to more clearly set forth the advantages and disadvantages of HTML5, and raise some issues that need attention and solutions to give newcomersexperiences and lessons learned.
