如今，数据推送技术在网站和Web应用中得到了广泛应用，比如在拍卖网络应用中推送新出价，在售书网站推送新评论，在在线游戏中推送新高分，推送用户感兴趣的新微博，等等。
本书是一本简明的数据推送技术指南，作者通过构建一个真实的例子，手把手地向读者展示如何利用HTML5 SSE（Server-Sent Events，服务端推送事件）这项非凡的技术，无需轮询或者用户交互，就可以将新数据从服务器端推送到客户端。
此外，本书还比较了数据推送和WebSocket的区别，阐释了如何使用不同的向后兼容解决方案，将应用的桌面和移动浏览器支持率从60%增加到99%。只要熟悉HTML、HTTP和基本的JavaScript，就可以开始你的学习之旅。

Content Description

《图灵程序设计丛书：HTML5数据推送应用开发》详细介绍了SSE（Server-Sent Event，服务端推送事件）。SSE是一种允许服务端向客户端推送新数据的HTML5技术。利用这种技术，网页可以迅速加载，并且能及时获得用户感兴趣的全新数据。相比数据拉取，SSE是更优的解决方案，能极大地降低延迟。《图灵程序设计丛书：HTML5数据推送应用开发》通过丰富的示例详细叙述了SSE的优势、它在的日常生活中的应用、目前的浏览器支持情况以及兼容解决方案等内容。
只要你略微了解一点HTML、HTTP和JavaScript，就可以顺利阅读《图灵程序设计丛书：HTML5数据推送应用开发》。

刘帅，百度前端高级研发工程师，毕业于哈尔滨工程大学，获得计算机科学与技术专业学士学位。毕业以来一直从事前端开发工作，先后就职于新浪、阿里巴巴、腾讯、百度，参与开发了基于HTML5技术的腾讯浏览器、QQforWindows8、百度打车WebApp版，现参与开发百度地图。

Comments

“数据推送是Web应用所涉及的一项关键技术，本书会告诉你如何利用全新的HTML5技术予以实现，并展示各种向后兼容方案的选择。不过在使用之前你仍然要回答这个问题：你的Web应用到底是否需要使用数据推送？当然，在你阅读完本书之后，答案便了然于心。”
——百度研发工程师贾铮

“如果你希望一有全新消息发布，你的Web客户端就立即更新，那么就来学习本书吧。本书展示了利用HTML5和数据推送技术，使你的用户在几乎所有现代平台上及时收到全新消息。”
——Peter MacIntyre，Paladin Business Solutions总裁

“HTML5 SSE是响应式动态交互Web前端的未来趋势。本书阐述了如何在客户端和服务器端实现SSE。此外，你还将学到PHP的相关知识，以及如何设计高性能、安全的Web应用。”
——Stuart Woodward，Hanamaru K.K.高级软件架构师

Introduction

人们对现代网络要求甚高：不仅要求页面美观，加载迅速，还必须有最新、有趣而且有价值的好内容。《图灵程序设计丛书：HTML5数据推送应用开发》探讨的是一项有助于满足后两个要求的技术：确保你的网站或网络应用用户获取最新的内容，并且毫不妥协地最大限度降低延迟。
《图灵程序设计丛书：HTML5数据推送应用开发》还关注现实生活中有实用价值的应用。第2 章以一个非常好玩的范例为基础，第6 章和第7 章用的是入门级的例子，其他章节则都是围绕现实生活中无处不在且又无法回避的完整应用。
读者对象
在现实生活中，你必须是一个健壮而谦恭、热情而客观的人，你还必须尊老爱幼并且极度热爱互联网。不过，本书没有现实世界那么苛刻，但你需要了解HTML（超文本标记语言）和HTTP（超文本传送协议），并且也知道HTML、CSS（层叠样式表）和JavaScript之间的区别。你至少应该能够阅读并理解基本的JavaScript，以便能理解客户端的代码。（当用到更为复杂的JavaScript 时，我们会在附注或附录中加以解释。）
本书尽可能保持服务端语言中立，所用到的代码大部分是简单的PHP 代码，因为对这类应用来说，PHP 言简意赅。只要你了解任何类C 语言，应该就不难读懂。如果有不懂的地方，请参阅附录C，那里会介绍一些PHP 相关知识。第2 章也会介绍使用Node.js 的例子。在后面的章节中，如果示例代码是PHP 专用的，我也会介绍如何用其他语言来实现。
最后，你需要有一台装有网络服务器（如Apache）的开发机，以便跟着文中的范例学。许多Linux 系统已经安装了Apache，如果没有，安装起来也不难。举个例子，在Ubuntu 系统中，在命令行终端输入sudo apt-get install lamp-server 1 就能一步安装Apache、PHP和MySQL。在Windows 系统中，有一个类似的集成包——XAMPP，它会给你提供所需要的一切。它还有Mac 版。
注1：如果这个命令不生效，试一下sudo apt-get install lamp-server。——译者注
本书结构：
SSE 的核心要素并不复杂，第2 章仅用了几页的篇幅就介绍了一个完整可运行的范例（包括前端和后端）。在那之前，第1 章会介绍HTML5 的一些背景知识、数据推送、可能会用到SSE 的应用，以及用作替代方案的技术。
从第3 章到第7 章，我们创建了一个完整的应用，尽可能使它贴近现实，同时又不会让你为那些不重要的细节而烦恼。这个应用所涉及的领域是金融数据。第3 章介绍这个应用的核心；第4 章对它做了一些重构和扩展；第5 章处理了数据推送应用中会出现的一些棘手的细节，比如复杂的数据、数据源无响应、套接字终止等；第6 章介绍了一种方案（长轮询），使我们的应用能够兼容那些尚未支持SSE 的台式机浏览器和手机浏览器；第7 章展示了两种更优但并不是所有浏览器都支持的方案。第3 章还用了一些篇幅，介绍如何开发我们的样本应用程序可以推送的真实且可重复使用的数据。虽然这与SSE 不直接相关，但这非常好地演示了数据推送应用中的易测性设计。
第8 章涵盖了SSE 协议的一些要素，我们没有将它们用于在其他章节创建的实用应用程序中。当然，我们介绍了没有使用它们的原因。这就引出了第9 章来介绍之前章节提到过但未详细阐述的安全方面的内容（cookie、权限控制、跨域）。
