How to send data using webrequest class method? - windows

Question

In my application I send data to a PHP server. I got code from the msdn website.
void SendPost()
{
var url = "http://www.nuatransmedia.com/ncampaign/mailserver/mail1.php";
// Create the web request object
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
// Start the request
webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
}
void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
// End the stream request operation
Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
// Create the post data
// Demo POST data
string postData = "Hello";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Add the post data to the web request
postStream.Write(byteArray, 0, byteArray.Length);
postStream.Close();
// Start the web request
webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
}
void GetResponseCallback(IAsyncResult asynchronousResult)
{
try
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response;
// End the get response operation
response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamReader = new StreamReader(streamResponse);
var Response = streamReader.ReadToEnd();
streamResponse.Close();
streamReader.Close();
response.Close();
}
catch (WebException e)
{
// Error treatment
// ...
}
}` void SendPost()
{

I got mail. But the body messages not show in my mail. Where did I make a mistake? In my PHP code I use postData variable to get my message.

For simpler HTTP usage the classes at http://mytoolkit.codeplex.com/wikipage?title=Http might help you...
These classes help to HTTP POST files (access via $_FILES["..."]). Also there is a RawData property (byte[]) to set the data directly.
(also GZIP, own timeout, and more is supported)
