我尝试扩展标准 MVC Auth 示例（http://www.asp.net/mvc/overview/security/create-an-aspnet-mvc-5-app-with-facebook-and-google-oauth2-and- openid-sign-on）使用 OpenID Connect 身份验证到 Thinktecture IdentityServer 的实例（https://github.com/IdentityServer/IdentityServer3.Samples/tree/master/source/Simplest%20OAuth2%20Walkthrough）。

我将“openid”范围添加到 IdentityServer 的范围中。我使用https://github.com/IdentityServer/IdentityServer3.Samples/blob/master/source/MVC%20Authentication/EmbeddedMvc ​​/Startup.cs 中的示例代码将额外调用添加到 userinfo 端点。

UseCookieAuthentication根据 MVC Auth 示例，身份验证中间件链中较高的部分是UseExternalSignInCookie.

当我在 中放置断点时OpenIdConnectAuthenticationNotifications.SecurityTokenValidated，我可以看到所有声明都很好地进入了。因此与 IdentityServer 的通信是正确的。

但是当我AccountController.ExternalLoginCallback接到电话时

var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();

总是返回 null。

当我使用 Google OAuth2 登录时，它不为空。

我怀疑UseOpenIdConnectAuthentication设置（或不设置）Cookie 信息的方式与UseCookieAuthentication提取方式之间存在不匹配。但我不知道如何解决这个问题。

事实证明，https://github.com/IdentityServer/IdentityServer3.Samples/blob/master/source/MVC%20Authentication/EmbeddedMvc ​​/Startup.cs 中的示例代码确实用类型覆盖了声明

"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier".

如果未找到此声明，则未找到 loginInfo。

问题代码（Startup.Auth.cs）：

var nid = new ClaimsIdentity(
    n.AuthenticationTicket.Identity.AuthenticationType,
    Constants.ClaimTypes.GivenName, // "given_name"
    Constants.ClaimTypes.Role // "role"
);

解决方案是保留原始声明，如下所示：

var nid = new ClaimsIdentity(
    n.AuthenticationTicket.Identity, 
    n.AuthenticationTicket.Identity.Claims
);

我遇到了类似的问题，虽然我没有想出为什么有时可以进行身份​​验证并带回身份声明的原因，但我确实通过下载和调试 Microsoft 代码设法找出了 ExternalLoginInfo 始终为空的原因。

对我来说，问题在于 OpenIdConnectAuthenticationOptions 中提供的ResponseType - 我将其设置为OpenIdConnectResponseType.Code这是不正确的......将其设置为OpenIdConnectResponseType.CodeIdToken使其始终如一地工作。

这是我的 Startup.Auth.vb 源代码的副本：

Public Sub ConfigureAuth(app As IAppBuilder)

    app.CreatePerOwinContext(Of ApplicationUserManager)(AddressOf ApplicationUserManager.Create)

   app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType)
    app.UseCookieAuthentication(New CookieAuthenticationOptions() With {
        .AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        .Provider = New CookieAuthenticationProvider() With {
            .OnValidateIdentity = SecurityStampValidator.OnValidateIdentity(Of ApplicationUserManager, ApplicationUser)(
                validateInterval:=TimeSpan.FromMinutes(30),
                regenerateIdentity:=Function(manager, user) user.GenerateUserIdentityAsync(manager))},
        .LoginPath = New PathString("/Account/Login")})
    app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie)
