如何发送参数上的HTTPS POST用C＃

Question

这里

我也问过 的如何使HTTPS后，现在工作正常。现在的问题是如何发送参数，名称查询，是至极JSON字符串：

{ “KEY1”： “VALUE1”， “KEY2”：{ “key21”： “val21”}}

我在做什么和不工作是：

HttpWebRequest q = (HttpWebRequest)WebRequest.Create(Host + ":" + Port);
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
q.Method = "POST";
q.ContentType = "application/json";
q.Headers.Add("JSON-Signature", GetFirma(query));
q.Credentials = new NetworkCredential(user,pass);

byte[] buffer = Encoding.UTF8.GetBytes("query=" + query);

q.ContentLength = buffer.Length;

using (Stream stream = q.GetRequestStream())
{
     stream.Write(buffer, 0, buffer.Length);                    
}

但是服务器总是回答说没有“查询”的参数。任何帮助？

提前感谢！

我会使用WebClient.UploadValues：

        using (WebClient client = new WebClient())
        {
            NameValueCollection fields = new NameValueCollection();
            fields.Add("query", query);
            byte[] respBytes = client.UploadValues(url, fields);
            string resp = client.Encoding.GetString(respBytes);
        }
