| 简介 |
| 内容简介书籍计算机书籍 Web开发领域的REST运动已经进行了很多年了，在REST的Richardson成熟度模型提出后，第3级——HATEOAS的应用——仍然没有得到广泛应用。事实上，其中一个难点在于客户端如何支持HATEOAS。之前很多REST相关书籍聚焦于如何打造服务端的RESTful API，本书则着重研究RESTful客户端，介绍了如何把一个针对服务端规约硬编码的定制客户端重构为一个支持HATEOAS的通用客户端，并提供了多格式支持、超媒体类型、版本化、微服务等相关问题的全面指导。本书附有所有样例代码的GitHub地址，方便读者快速理解和实践。本书适合Web应用开发者，尤其适合希望Web应用程序的服务端与客户端能够独立演化的Web架构师。 |
