1.Web网站的授权(oAuth2.0)
- Client 第三方应用(需要做鉴权的业务网站、业务系统)
- UserAgent 用户代理(浏览器)
- Resource Owner 用户授权(用户手动点击【同意】按钮,授权使用第三方登录渠道),第三方渠道授权登录:微信同意登录、或qq授权登录或微博 、GitHub、Gitee,这里使用Gitee做当前网站的第三方授权渠道
- 用户认证,用户输入账号和密码(gitee账号&密码),账号会通过第三方授权服务器检验(gitee服务器、门户服务),如果校验通过会返一个授权码Authorization Code到业务系统(业务网站)
- 网站再次发请求并携带上一步获取的授权码Authorization Code去访问第三方授权服务(gitee、门户服务),第三方授权服务会返回一个访问令牌Access token
- 以后浏览器就可以通过token访问令牌跳过第三方授权直接访问服务器任意请求,token访问令牌可能需要做jwt解密(token校验)或token失效返新token操作
点击gitee按钮,跳转到gitee码云登录页,如果gitee账号登录成功,会redirect重定向到咱们自动的业务网站系统首页
在做这套第三方渠道跳转前需要,需要在Gitee上创建第三方应用,这个应用需要配置如下:
- Client ID :创建应用时自动生成的唯一标识
- Client Secret :创建应用时自动生成的密钥
- 重定向回调地址url:(需要手动配置)第三方登录授权成功后需要重定向到系统的首页
- 授权码Authorization Code
