我正在玩 DevDefined.OAuth - .Net http://code.google.com/p/devdefined-tools/wiki/OAuth的 OAuth 消费者和提供者实现，并在配置服务端点后启动 ExampleConsumerSite 项目我的 IIS 7 Web 服务器，我收到以下错误：

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

我注意到 oauth_token GET 参数为空。在跟踪这一点时，错误源来自 Default.aspx.cs 页面的第 12 行：

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);
}

虽然我不确定这是否与配置服务端点有关，但我正在从 VS2008 运行消费者项目并在 IIS 上托管服务。请指教。

现在工作。错误是由于 OAuthChannel 中的页面 RequestToken.aspx 没有继承正确的类，因此当消费者站点请求令牌时，导致 ServiceProvider 端出现内部服务器错误。
