Send data using Post method from asp.net to EPOS Device

Hello Experts,
My aim is to send data to the EPOS device from asp.net page when requested. I am having following code

string URLAuth = "http://xyz.com/FarmerUpload.aspx";
  string postString = string.Format("inputEmailHandle={0}&name={1}&inputPassword={2}", FarmerCode, FarmerData);

  const string contentType = "application/x-www-form-urlencoded";
  System.Net.ServicePointManager.Expect100Continue = false;

  CookieContainer cookies = new CookieContainer();
  HttpWebRequest webRequest = WebRequest.Create(URLAuth) as HttpWebRequest;
  webRequest.Method = "POST";
  webRequest.ContentType = contentType;
  webRequest.CookieContainer = cookies;
  webRequest.ContentLength = postString.Length;
  webRequest.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";
 webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
  webRequest.Referer = "http://xyz.com/FarmerUpload.aspx";

Open in new window


But I am unable to send data to the EPOS Device (This device is configured to receive the data in POST method only)
I am able to get the data sent from EPOS device using query string. Based on that I need to send the data.

There are some flaws. First of all your post data string containes three placeholders, but you're only providing two values. Then you don't execute the post.

This could work:

const string POST_DATA = "inputEmailHandle={0}&name={1}&inputPassword={2}";
const string REFERER = "http://xyz.com/FarmerUpload.aspx";
const string URL = "http://xyz.com/FarmerUpload.aspx";

WebRequest request = WebRequest.Create(URL);
request.Method = "POST";            
string postData = string.Format(POST_DATA, FarmerCode, FarmerData);
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
request.Referer = REFERER;
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse response = request.GetResponse();

Console.WriteLine(((HttpWebResponse)response).StatusDescription);

dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
reader.Close();
dataStream.Close();
response.Close();
