OAuth Consumer request for token from ServiceProvider returns InternalServerError
- by chridam
I'm playing around with DevDefined.OAuth - an OAuth consumer and provider implementation for .Net http://code.google.com/p/devdefined-tools/wiki/OAuth and on launching the ExampleConsumerSite project after configuring the service endpoints on my IIS 7 web server, I'm receiving the following error:
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%3A8080/RequestToken.aspx?oauth%5Fcallback=oob&oauth%5Fnonce=94efde0b-dd45-4cee-8253-7496cef0b877&oauth%5Fconsumer%5Fkey=key&oauth%5Fsignature%5Fmethod=PLAINTEXT&oauth%5Ftimestamp=1252512419&oauth%5Fversion=1.0&oauth%5Ftoken=&oauth%5Fsignature=secret%2526 failed.

I've noticed the oauth_token GET parameter is empty. On tracing this, the error source is from the line 12 of Default.aspx.cs page:
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);
}
While I'm not sure if this has to do with configuring the service endpoints but I'm running the consumer project from VS2008 and hosting the service on IIS. Please advice.
