十分钟搞定单点登录
单点登录(SSO)简化了用户体验,使用户能够在访问多个应用时只需一次登录。这提高了用户满意度,减少了密码遗忘的风险,同时增强了安全性。但是,实现单点登录并不容易,需要应用程序实现和认证服务器的交互逻辑,增加了应用程序的开发工作量。例子中的安全策略中提供了 OpenID Connect (OIDC) 的能力,无需对应用做过多的修改,在十分钟内即可立刻实现单点登录。
当采用单点登录之后,用户只需要登录一次,就可以访问多个应用系统。SSO 通常由一个独立的身份管理系统来完成,该系统为每个用户分配一个全局唯一的标识,用户在登录时,只需要提供一次身份认证,就可以访问所有的应用系统。我们在使用一些网站时,经常会看到“使用微信登录”、“使用 Google 账户登录”等按钮,这些网站就是通过 SSO 来实现的。
采用单点登录有以下几个好处:
用户只需要登录一次,就可以访问多个应用系统,不需要为每个应用系统都单独登录。
应用系统不需要自己实现用户认证,只需将认证工作交给单点登录系统,可以大大减少应用系统的开发工作量。
使用 OIDC 单点登录, 可以简化客户端编写流程, 专注于功能实现而不用重复撰写登录部分功能代码, 也不用直接接触身份验证数据库, 剥离繁琐的重复劳动部分.

添加Oidc授权配置
新建 OidcProfile.cs 文件

Program.cs 加入授权相关
其中要加入Razor的cshtml支持, 因为登录要依靠管道跳转. 上下有两行都注释在文件内了.
