- 阮一峰 – 理解 OAuth 2.0 (opens new window)
- OAuth2 CSRF攻击
OAuth2是一种授权框架，提供了一套详细的授权机制（指导）。用户或应用可以通过公开的或私有的设置，授权第三方应用访问特定资源。
应用场景：OAuth2用在使用第三方账号登录的情况(比如使用weibo, qq, github登录某个app)
- OAuth2是一个相对复杂的协议, 有4种授权模式：
- 授权码模式（authorization code）
- 密码模式（resource owner password credentials）
- 客户端模式（client credentials）
- 简化模式（implicit）
