WebAPI OAuth UseOAuthBearerAuthentication daje "sekwencja zawiera więcej niż jeden element" błędzie

Question

skonfigurowałem moje WebAPI OAuth 2.0 w tych wierszach:

app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions 
    { 
     Provider = new OAuthBearerAuthenticationProvider(), 
    }); 

    app.UseOAuthBearerTokens(OAuthOptions); 

Ale to daje mi następujący błąd na każde żądanie:

Message : An error has occurred. 
ExceptionMessage : Sequence contains more than one element 
ExceptionType : System.InvalidOperationException 
StackTrace : at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source)

    at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() 
    at System.Web.Http.Dispatcher.HttpControllerDispatcher.d__1.MoveNext() 

My OAuthOptions jest:

OAuthOptions = new OAuthAuthorizationServerOptions 
    { 
     TokenEndpointPath = new PathString("/Token"), 
     Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory), 
     AuthorizeEndpointPath = new PathString("/Account/ExternalLogin"), 
     AccessTokenExpireTimeSpan = TimeSpan.FromDays(14), 
     AllowInsecureHttp = true, 
    }; 
} 

Jeśli komentarz UseOAuthBearerAuthentication wszystko jest ok! Nie dostosowałem jeszcze OAuthBearerAuthenticationProvider i używam go bezpośrednio, ale dlaczego powoduje błąd?

Answer 1

To powinien być błąd! Użyj

app.UseOAuthAuthorizationServer(OAuthOptions);

zamiast

app.UseOAuthBearerTokens(OAuthOptions);
