Thinktecture Identity Server v3如何保持外部提供商的聲明?

[英]Thinktecture Identity Server v3 How to keep Claims from external providers?

我正在嘗試遵循簡單的指南mvcGettingStarted 現在,我已經實現了GoogleAuthenticationFacebookAuthentication提供程序,一切都按預期工作,我實際上可以登錄,如果我使用我的身份服務器登錄,我還獲得了每個用戶的角色聲明。 我想知道,如果我想保留外部提供商提供的所有索賠怎么辦? 簡單的例子。 這就是我的Facebook提供商設置的樣子:

var facebookOptions = new FacebookAuthenticationOptions() {
            AuthenticationType = "Facebook",
            Caption = "Sign in with Facebook",
            AppId = "*****",
            AppSecret = "****",
            SignInAsAuthenticationType = signInAsType,
            Provider = new FacebookAuthenticationProvider() {
                OnAuthenticated = (context) => {

                    foreach (var x in context.User) {
                        context.Identity.AddClaim(new Claim(x.Key, x.Value.ToString()));
                    }

                    return Task.FromResult(context);
                }
            },
        };

        facebookOptions.Scope.Add("email");
        facebookOptions.Scope.Add("public_profile");
        facebookOptions.Scope.Add("user_friends");

        app.UseFacebookAuthentication(facebookOptions);

在每個循環中我試圖將所有Facebook聲明存儲在Identity中,但是當我回到SecurityTokenValidated回調時,我的身份沒有它們。

app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions() {
            Authority = "https://localhost:44302/identity/",
            ClientId = "my_client",
            Scope = "openid profile roles email",
            RedirectUri = "https://localhost:44302/",
            ResponseType = "id_token token",
            SignInAsAuthenticationType = "Cookies",
            UseTokenLifetime = false,
            Notifications = new OpenIdConnectAuthenticationNotifications() {

                SecurityTokenValidated = async context => {
                    //let's clean up this identity

                    //context.AuthenticationTicket.Identity doesn't have the claims added in the facebook callback
                    var nid = new ClaimsIdentity(
                        context.AuthenticationTicket.Identity.AuthenticationType,
                        Constants.ClaimTypes.GivenName,
                        Constants.ClaimTypes.Role);
                    ........

是因為我在操縱兩個不同的身份嗎? 有沒有正確的方法來實現我想要做的事情? 謝謝。

正如@ brock-allen所說,用戶服務是正確的道路。 所以我繼續實現了一個簡單的UserService

public class UserService {
    private static InMemoryUserService _service = null;
    public static InMemoryUserService Get() {
        if(_service == null)
            _service = new InMemoryUserService(Users.Get());

        return _service;
    }
}

在我的工廠注冊了我的用戶服務

public void Configuration(IAppBuilder app) {
        AntiForgeryConfig.UniqueClaimTypeIdentifier = Constants.ClaimTypes.Subject;
        JwtSecurityTokenHandler.InboundClaimTypeMap = new Dictionary<string, string>();

        var factory = InMemoryFactory.Create(
            users: Users.Get(),
            clients: Clients.Get(),
            scopes: Scopes.Get());
        factory.UserService = new Registration<IUserService>(resolver => UserService.Get());

.....

(當然那是我的Startup類中的Configuration方法)

所以現在我可以在外部提供程序(在本例中是facebook)的身份驗證回調中驗證外部用戶,指定我需要的所有聲明:

var facebookOptions = new FacebookAuthenticationOptions() {
            AuthenticationType = "Facebook",
            Caption = "Sign in with Facebook",
            AppId = "******",
            AppSecret = "*******",
            SignInAsAuthenticationType = signInAsType,
            Provider = new FacebookAuthenticationProvider() {
                OnAuthenticated = (context) => {

                    foreach (var x in context.User) {
                        context.Identity.AddClaim(new Claim(x.Key, x.Value.ToString()));
                    }

                    ExternalIdentity identity = new ExternalIdentity() {
                        Claims = context.Identity.Claims,
                        Provider = "Facebook",
                        ProviderId = "Facebook"
                    };
                    SignInMessage signInMessage = new SignInMessage();

                    UserService.Get().AuthenticateExternalAsync(identity, signInMessage);


                    return Task.FromResult(context);
                }
            },
        }

現在,我可以做到

List<Claim> claims = await UserService.Get().GetProfileDataAsync(User as ClaimsPrincipal) as List<Claim>;

並且看到我的用戶在認證期間提供了facebook提供的所有聲明。 當然這段代碼僅用於測試目的,它可以進行很多改進。

您可以在自定義用戶服務實現中執行此操作。 默認設置使外部提供商的聲明可用。 自定義用戶服務的文檔: https//identityserver.github.io/Documentation/docsv2/advanced/userService.html
