<blockquote>
<p><strong>关于RESTful风格：</strong><br>缩写：REST （不是”rest”这个单词）<br>外文名：Representational State Transfer，简称 REST。中文名：表现层状态转移，即<strong>资源在网络中以某种表现形式进行状态转移。</strong><br>提出时间：2000年。<br>属性：一种软件架构风格。（以Web为平台的。web服务的架构风格，前后端接口时候用到。）<br>**理解：**URL中只使用名词来定位资源，用HTTP协议里的动词（GET、POST、PUT、DELETE）来实现资源的增删改查操作。</p>
</blockquote>
