如何通过 Digg API 提取 Digg 数据

Question

我正在尝试使用以下 URL 为用户提取 Digg 数据：

“http://services.digg.com/user/vamsivanka/diggs?count=25&appkey=34asd56asdf789as87df65s4fas6”，

并且 Web 响应抛出错误“远程服务器返回错误：(403) 禁止。 ”

请告诉我。

public static XmlTextReader CreateWebRequest(string url)
        {
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
            webRequest.UserAgent = ".NET Framework digg Test Client";
            webRequest.Credentials = System.Net.CredentialCache.DefaultCredentials;
            webRequest.Accept = "text/xml";
            HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
            System.IO.Stream responseStream = webResponse.GetResponseStream();
            XmlTextReader reader = new XmlTextReader(responseStream);
            return reader;
        }
