我已经获得了两项服务，其中 ist 服务用于登录目的，它将返回一个 xml 节点令牌，我将在所有其他服务调用中将其添加为标头，

在附加的示例代码中，函数CreateObject()中有两个函数，我正在点击登录服务并且能够成功获取响应，并且从响应中我获取了令牌并使用令牌搜索（字符串令牌）调用其他函数并将令牌传入标题，但它给出了一个例外[System.Net.WebException] = {"The remote server returned an error: (403) Forbidden."}

但是当我在 chrome Advanced Rest Client 中看到它给出了预期的响应

任何朝着正确方向的建议或解决方案都将受到高度评价

请参阅下面的代码

 private  void CreateObject()
    {        
        try
        {
            string abc = "";
            Stream datastream;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("www.example.com/abc/login");
            request.CookieContainer = new CookieContainer();
            request.AllowAutoRedirect = true;
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
            request.ContentType = "application/x-www-form-urlencoded";
            request.Accept = "application/xml";
            request.KeepAlive = true;
            String postData = "";
            request.Method = "POST";
            postData = String.Format("username={0}&password={1}", "sample", "sample");
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            request.ContentLength = byteArray.Length;
            datastream = request.GetRequestStream();
            datastream.Write(byteArray, 0, byteArray.Length);


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

            {
                sourceCode = reader.ReadToEnd();
            }
            int pos = sourceCode.IndexOf("<?");
            string xmlpart = sourceCode.Substring(pos);
            //XmlReader reader1 = XmlReader.Create(sourceCode);
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xmlpart);
            XmlNodeList objNodeList = doc.GetElementsByTagName("token");
           string tokens = objNodeList[0].ChildNodes.Item(0).InnerText.Trim();
          search(tokens);

        }
        catch (Exception e)
        {

        }
    }

     public void search(string token)
        {

最后我弄清楚了问题所在

我正在为这两个请求创建新的 cookie 容器

request.CookieContainer = new CookieContainer();

因此服务器无法进行身份验证

使用此代码解决了错误

CookieContainer cookieJar = new CookieContainer();
    private  void CreateObject()
        {        
            try
            {
                string abc = "";
                Stream datastream;
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create("www.example.com/abc/login");
                request.CookieContainer = cookieJar;
                request.AllowAutoRedirect = true;
                request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
                request.ContentType = "application/x-www-form-urlencoded";
                request.Accept = "application/xml";
                request.KeepAlive = true;
                String postData = "";
                request.Method = "POST";
                postData = String.Format("username={0}&password={1}", "sample", "sample");
                byte[] byteArray = Encoding.UTF8.GetBytes(postData);
                request.ContentLength = byteArray.Length;
                datastream = request.GetRequestStream();
                datastream.Write(byteArray, 0, byteArray.Length);


                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                datastream = response.GetResponseStream();
                String sourceCode = "";
                using (StreamReader reader = new StreamReader(datastream))
                {
                    sourceCode = reader.ReadToEnd();
                }
                int pos = sourceCode.IndexOf("<?");
                string xmlpart = sourceCode.Substring(pos);
                //XmlReader reader1 = XmlReader.Create(sourceCode);
                XmlDocument doc = new XmlDocument();
                doc.LoadXml(xmlpart);
                XmlNodeList objNodeList = doc.GetElementsByTagName("token");
               string tokens = objNodeList[0].ChildNodes.Item(0).InnerText.Trim();
              search(tokens);

            }
            catch (Exception e)
            {

            }
        }

         public void search(string token)

            }
