NullPointer para la solicitud de yahoo openid, pero no de google (dotnetopenid)

Question

Estoy programación haciendo un apretón de manos openid con Yahoo y Google. Google está muy bien, pero Yahoo lanza un puntero nulo:

seguimiento de la pila:

   System.NullReferenceException: Object reference not set to an instance of an object.

código de invocación:

        var openid = new OpenIdRelyingParty();
        IAuthenticationRequest request = openid.CreateRequest(
            Identifier.Parse(
                GetEndpoint()),
                new Realm(realm),
                new Uri(returnUri));

        // Require some additional data
        request.AddExtension(new ClaimsRequest
        {
            Email = DemandLevel.Require,
            FullName = DemandLevel.Request,
            PostalCode = DemandLevel.Request
        });

        try
        {
            request.RedirectToProvider();
        } catch (ThreadAbortException)
        {
        }

código recibir (y la fuente de la excepción)

        var openId = new OpenIdRelyingParty();
        var response = openId.GetResponse(); <-- exception happens here

¿qué pasa? Lo extraño es que la pieza yahoo estaba trabajando recientemente, y no he cambiado la versión de biblioteca ...

Answer 1

Parece que es un problema en el extremo de yahoo:

3.3.1 maneja.

Answer 2

Creo que quiere mirar su createRequest. También no se puede coger ThreadAbortException, que se auto-propaga. Por lo tanto usted necesita coger dos veces.
