金数据post提交数据，“远程服务器返回错误: (401) 未经授权。”
有没有解决方法呢？
以下是post方法



public static string Post(string postUrl, NameValueCollection postParam)

    {

        try

        {

            ServicePointManager.ServerCertificateValidationCallback = (RemoteCertificateValidationCallback)Delegate.Combine(ServicePointManager.ServerCertificateValidationCallback, new RemoteCertificateValidationCallback(ValidateServerCertificate));

            ServicePointManager.Expect100Continue = false;

            string paramStr = string.Empty;

            foreach (string item in postParam)

            {

                paramStr += string.Format("{0}={1}&", item, postParam[item]);

            }

            byte[] bs = Encoding.UTF8.GetBytes(paramStr.TrimEnd('&'));

            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(postUrl);

            //参照浏览器的请求报文 封装需要的参数 这里参照ie9

            //浏览器可接受的MIME类型

            req.Accept = "text/html, application/xhtml+xml, */*";

            //包含一个URL，用户从该URL代表的页面出发访问当前请求的页面

            req.Referer = "https://jinshuju.net/f/z1usAE";

            //浏览器类型，如果Servlet返回的内容与浏览器类型有关则该值非常有用

            req.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko";

            req.ContentType = "application/x-www-form-urlencoded";

            //请求方式

            req.Method = "POST";

            //是否保持常连接

            req.KeepAlive = false;

            req.Headers.Add("Accept-Encoding", "gzip, deflate");

            //表示请求消息正文的长度

            req.ContentLength = bs.Length;

            //req.Headers.Add("csrf-param", "authenticity_token");

            //req.Headers.Add("csrf-token", "fO6iOKdw4xxUqJ7Ck5y/j7Ae/22VADhSW0vGu1s8SJC+ZFaqKOcdn8hlR7ppE2l83AYuyr9quliHszgEeZbMrA==");



            using (Stream reqStream = req.GetRequestStream())

            {

                reqStream.Write(bs, 0, bs.Length);

            }

            using (WebResponse wr = req.GetResponse())

            {

                Stream responseStream = wr.GetResponseStream();

                StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8);

                string retString = streamReader.ReadToEnd();

                return retString;

            }

        }

        catch (Exception ex)

        {

            return ex.Message;

        }

    }
