内容简介

随着互联网的普及，合作共赢成了一个越来越受重视的话题。一些成熟的互联网企业，需 要与众多的第三方企业进行合作，以便为自己的用户提供丰富的个性化应用。在这个过程中， 企业需要将自身的一些能力(API)开放给第三方合作企业，具体的实现形式一般是搭建一个 专门的开放平台系统。无论企业通过何种方式来开放自身的能力，授权都是一个绕不开的话题。本书将通过 8 章 来详细对授权的相关内容进行阐述，主要内容包括 OAuth 2 概述、开放平台整体架构、实战中 的授权模式、OpenID 从理论到实战、授权码授权模式回调地址实战、签名、授权信息、基于 Spring Security 的 OAuth 2 实战。

作者介绍
