我找到了关于社交登录的非常有用的科尔多瓦示例https://github.com/aspnet-contrib/AspNet.Security.OpenIdConnect.Samples/ 我已经在此示例之上构建了自己的应用程序，我非常坚持奇怪的问题。第一个输出来自示例，第二个来自我的应用程序。我不知道为什么在我的应用程序中使用“Identity.External”身份验证方案而不是“ServerCookie”。这导致身份验证失败。
示例的输出：
Microsoft.AspNetCore.Hosting.Internal.WebHost: Information: Request starting HTTP/1.1 GET http://localhost:54540/signin-facebook?code=***
Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationMiddleware: Information: AuthenticationScheme: ServerCookie signed in.
并从我的应用程序中输出：
Microsoft.AspNetCore.Hosting.Internal.WebHost: Information: Request starting HTTP/1.1 GET http://localhost:62892/signin-facebook?code=***
Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationMiddleware: Information: AuthenticationScheme: Identity.External signed in.
