如何使用RESTSHARP连接HUAWEI HILINK

Question

我使用以下代码连接huawei hilink，但它总是返回错误。

首先我通过

获取令牌和会话

http://192.168.8.1/api/webserver/SesTokInfo

你能帮我解决一下这个问题吗？

        string resulta = PostAndGetHTML("http://192.168.8.1/api/webserver/SesTokInfo");
        string tok = resulta.Substring(57, 32);
        string ses = resulta.Substring(108, 128);
        Postxml("http://192.168.8.1/api/user/login", tok, ses);

   public string PostAndGetHTML(string targetURL)
    {


        string html = string.Empty;
        string url = targetURL;

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.AutomaticDecompression = DecompressionMethods.GZip;

        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        using (Stream stream = response.GetResponseStream())
        using (StreamReader reader = new StreamReader(stream))
        {
            html = reader.ReadToEnd();
        }
        return html; 
    }


   public  void Postxml(string destinationUrl, string token, string ses)
    {
        var client = new RestClient();
          string rawXml = @"<?xml version=""1.0"" encoding=""utf-8""?><request><Username>admin</Username><Password>" + Base64Encode("admin") + @"</Password></request>";
        client.BaseUrl = new Uri(destinationUrl);
        var request = new RestRequest(Method.POST);
        request.AddHeader("__RequestVerificationToken", token);
        request.AddCookie("cookie",ses);
        request.Timeout = 3000;
        request.ReadWriteTimeout = 3000;


        request.AddParameter("text/html", rawXml, ParameterType.RequestBody);
        IRestResponse response = client.Execute(request);

    }
