你也许曾经建立过可供他人使用的网站,但是,你能否创建可供机器使用的网站?万维网(World Wide Web)不仅仅只是一个巨大的分布式应用——应该把它视为一个分布式计算平台。Web services、聚合(mashup)和Ajax应用都以Web作为平台。而今天的Web services技术早已失去了Web赖以成功的简洁性,它们并不像Web那样工作,并且正日益丧失其原有的优势。
本书让“Web”回归Web services。它阐述了如何以你日常所使用的技术访问可编程的Web。其关键就在于REST,它是驱动Web的架构样式。本书包括以下内容:
·强调Web基础技术的力量 —— HTTP应用协议、URI命名标准与XML标记语言
·介绍面向资源的架构(ROA),设计RESTful Web Services的常识规则集合
·揭示RESTful的设计如何比远程过程调用(RPC)更为简单、具有更多功能以及扩展性
·包含RESTful Web services的真实案例,如Amazon的简单存储服务与Atom发布协议等
·探讨各种流行编程语言的Web services客户端
