HttpWebRequest For Atom URL返回HTML內容

Question

我正在嘗試將Atom提要加載到字符串中，並且正在使用以下方法：

private string GetXml(string urlString)
        {
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;
            StringBuilder sb = new StringBuilder();
            // Create a new HttpWebRequest object.Make sure that 
            // a default proxy is set if you are behind a firewall.
            HttpWebRequest myHttpWebRequest1 =
              (HttpWebRequest)WebRequest.Create(urlString);

            myHttpWebRequest1.KeepAlive = false;
            myHttpWebRequest1.ContentType = "text/xml";
            // Assign the response object of HttpWebRequest to a HttpWebResponse variable.
            HttpWebResponse myHttpWebResponse1 =
              (HttpWebResponse)myHttpWebRequest1.GetResponse();

            Debug.WriteLine("\nThe HTTP request Headers for the first request are: \n{0}", myHttpWebRequest1.Headers);

            Stream streamResponse = myHttpWebResponse1.GetResponseStream();
            StreamReader streamRead = new StreamReader(streamResponse);
            Char[] readBuff = new Char[256];
            int count = streamRead.Read(readBuff, 0, 256);
            Debug.WriteLine("The contents of the response are.......\n");
            while (count > 0)
            {
                String outputData = new String(readBuff, 0, count);
                sb.Append(outputData);
                count = streamRead.Read(readBuff, 0, 256);
            }
            // Close the Stream object.
            streamResponse.Close();
            streamRead.Close();
            return sb.ToString();
        }

這適用於大多數提要，但是http://tipsforbbq.com/RSS在我的瀏覽器中顯示為原子提要，它返回HTML頁面（可在http://tipsforbbq.com/找到）。 有誰知道為什么會這樣？

Answer 1

我在HttpWebRequest上也遇到了類似的問題，並使用了著名的用戶代理解決了該問題。

myHttpWebRequest1.UserAgent= @"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.1";

希望對您有所幫助。
