求教关于豆瓣接口saying 要求使用的http header传参，求示例。

先声明~ 获取的accesstoken 是对的签名方法也是对的，因为我使用该accesstoken 和签名方法可以获取到用户信息当然是用get请求，那么根据官网文档说明
“如果你发现豆瓣提示你没有传递OAuth参数（no auth错误），那么请检查一下你是否在POST、PUT、DELETE请求中使用了url或post form传递OAuth参数。 ”
本人测试返回 403 容错后获取提示no auth access error，
呈上代码，求批评求教育



public string getHeader(string accesstoken)

        {

            Uri uri = new Uri(saying);

            string nonce = GenerateNonce();

            string timeStamp = GenerateTimeStamp();

            string normalizeUrl, normalizedRequestParameters;

            string sig = GenerateSignature(uri, AppKey, AppKeySecret, accesstoken, AccessTokenSecret, "POST", timeStamp, nonce, out normalizeUrl, out normalizedRequestParameters, true);

            sig = UrlEncode(sig);

            //构造OAuth头部             

            StringBuilder oauthHeader = new StringBuilder();

            oauthHeader.AppendFormat(":OAuth realm=\"http://sp.example.com/\",oauth_consumer_key={0},", AppKey);

            oauthHeader.AppendFormat("oauth_token={0},", accesstoken);

            oauthHeader.AppendFormat("oauth_signature_method={0},", "HMAC-SHA1");

            oauthHeader.AppendFormat("oauth_signature={0},", sig);

            oauthHeader.AppendFormat("oauth_timestamp={0},", timeStamp);

            oauthHeader.AppendFormat("oauth_nonce={0},", nonce);

            oauthHeader.AppendFormat("oauth_version={0}", "1.0");

            return oauthHeader.ToString();

        }



        public string AddSaying(string context,string accesstoken,DataType type)

        {

            string oauthHeader = getHeader(accesstoken);

            //构造请求

            StringBuilder requestBody =  new StringBuilder("<?xml version='1.0' encoding='UTF-8'?>");

            requestBody.Append("<entry xmlns:ns0=\"http://www.w3.org/2005/Atom\" xmlns:db=\"http://www.douban.com/xmlns/\">");           requestBody.Append("<content>C# OAuth</content>");

            requestBody.Append("</entry>");

            Encoding encoding = Encoding.GetEncoding("UTF-8");

            byte[] data = encoding.GetBytes(requestBody.ToString());

            // Http Request的设置

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(saying));

            request.Headers.Set("Authorization", oauthHeader);

            request.ContentType = "application/atom+xml";

            request.Method = "POST";

            request.ContentLength = data.Length;

            Stream requestStream = request.GetRequestStream();

            requestStream.Write(data, 0, data.Length);

            requestStream.Close();

            try

            {

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                StreamReader stream = new StreamReader(response.GetResponseStream(), System.Text.Encoding.UTF8);                             string responseBody = stream.ReadToEnd();

                stream.Close();

                response.Close();

                return("发送广播成功");



            }

            catch (WebException e)

            {

                StreamReader stream = new StreamReader(e.Response.GetResponseStream(), System.Text.Encoding.UTF8);

                string responseBody = stream.ReadToEnd();

                stream.Close();

                return  "发送广播失败，原因: " + responseBody;

            }

        }
