Ref*_*eft 9 .net c# oauth-2.0 asp.net-identity asp.net-core
我使用自己的JWT令牌身份验证,而不使用默认模板附带的asp.net身份。我到处都到处寻找有关如何在没有asp.net身份的情况下实现外部身份验证的文档/指南,但是所有文章都涉及asp.net身份验证。
我已经设法将用户重定向到google登录页面(使用ChallengeResult),但是当提供程序重定向回该应用程序时,我失败了。
我删除了:app.UseAuthentication(); 在Startup.cs中,(禁用身份验证),然后可以使用回调函数,但是我不知道如何在不使用登录管理器的情况下从响应中检索数据。

解决:
没有将IAuthenticationSignInHandler配置为处理方案的登录:Bearer
我必须添加一个cookie处理程序,该处理程序将临时存储外部身份验证的结果,例如,外部提供程序发送的声明。这是必要的,因为在完成外部身份验证过程之前,通常涉及几个重定向。

这里的重要部分是CookieAuthenticationDefaults.AuthenticationScheme。这是一个字符串常量,用于存储“ Cookies”。虽然我们可以在代码中直接使用字符串“ Cookies”,但使用预设常量会更安全。这是AddCookies默认情况下赋予该功能的身份验证方案名称。它可以帮助您参考cookie身份验证。
现在是时候从回调操作中外部认证提供的声明中检索用户信息了。

瞧!现在,我们可以使用一些用户信息!
