OAuth La richiesta del token da parte di ServiceProvider da parte del consumatore restituisce InternalServerError

Question

Sto giocando con DevDefined.OAuth - un'implementazione di consumer e provider OAuth per .Net http://code.google.com/p/devdefined-tools/wiki/OAuth e all'avvio del progetto ExampleConsumerSite dopo aver configurato gli endpoint di servizio sul mio server Web IIS 7, sto ricevendo il errore seguente:

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.
status code: InternalServerError

Ho notato che il parametro GET oauth_token è vuoto. Nel tracciare questo, l'origine dell'errore proviene dalla riga 12 della pagina 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);
}

Anche se non sono sicuro che ciò abbia a che fare con la configurazione degli endpoint del servizio, ma sto eseguendo il progetto consumer da VS2008 e ospitando il servizio su IIS. Per favore, consigli.

Ora funziona. L'errore era dovuto alla pagina RequestToken.aspx in OAuthChannel che non ereditava la classe corretta dietro, quindi quando il sito del consumatore stava facendo una richiesta per un token che ha provocato un errore interno del server sul lato ServiceProvider.
