OAuth Demande de client pour le jeton de ServiceProvider renvoie InternalServerError

Question

Je joue avec DevDefined.OAuth - une implémentation de consommateur et de fournisseur OAuth pour .Net http://code.google.com/p/devdefined-tools/wiki/OAuth et sur le lancement du projet ExampleConsumerSite après avoir configuré les points de terminaison de service sur mon serveur Web IIS 7, Je reçois l'erreur suivante:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Exception: Request for uri: http://localhost:8080/RequestToken.aspx?oauth_callback=oob&oauth_nonce=94efde0b-dd45-4cee-8253-7496cef0b877&oauth_consumer_key=key&oauth_signature_method=PLAINTEXT&oauth_timestamp=1252512419&oauth_version=1.0&oauth_token=&oauth_signature=secret%2526 failed.

J'ai remarqué le paramètre oauth_token GET est vide. En traçant cela, la source d'erreur est de la ligne 12 de la page Default.aspx.cs:

IToken requestToken = session.GetRequestToken(); 

protected void oauthRequest_Click(object sender, EventArgs e) 
{ 
    OAuthSession session = CreateSession(); 

    IToken requestToken = session.GetRequestToken(); 

    if (string.IsNullOrEmpty(requestToken.Token)) 
    { 
    throw new Exception("The request token was null or empty"); 
    } 

    Session[requestToken.Token] = requestToken; 

    string callBackUrl = "http://localhost:" + HttpContext.Current.Request.Url.Port + "/Callback.aspx"; 

    string authorizationUrl = session.GetUserAuthorizationUrlForToken(requestToken, callBackUrl); 

    Response.Redirect(authorizationUrl, true); 
} 

Bien que je ne sais pas si cela a à voir avec la configuration des points de terminaison de service mais je suis en cours d'exécution du consommateur projet de VS2008 et l'hébergement du service sur IIS. Veuillez nous conseiller

Travailler maintenant. L'erreur était due à la page RequestToken.aspx dans le OAuthChannel n'héritant pas la classe correcte derrière ainsi quand le site de consommateur faisait une demande pour un jeton qui a entraîné une erreur de serveur interne du côté ServiceProvider.
