Title: Message

Hello,

I am having HttpWebRequest, HttpWebResponse problems. Here is an example which is similar to what I'm trying to do.

 

 

using System;
using System.IO;
using System.Diagnostics;
using System.Text;
using System.Threading;
using System.Net;

 

namespace ConsoleApplication4
{

 

 public class Connect
 {
  private const int BUFFER_SIZE= 1024;
  private int TIME_OUT;
  private ManualResetEvent m_eventDone;
  private HttpWebRequest m_httpReq;
  private byte[] m_btRead;
  private StringBuilder m_sbResp;
  private string m_sPost;
  private Stream m_stResponse;
  private Decoder m_dec = Encoding.UTF8.GetDecoder();
  private string m_sResp;
  private bool m_bGotResponse = false;

 

  public Connect()
  {
   m_eventDone = new ManualResetEvent(false);
   m_btRead = new byte[BUFFER_SIZE];
   m_sbResp = new StringBuilder(String.Empty);
  }

 

  public int HUBTimeOut
  {
   set { TIME_OUT = value *1000;}
  }
  public string strResponse
  {
   get { return m_sResp;}
  }

 

  public bool GotResponse
  {
   get { return m_bGotResponse;}
  }

 

  public string postToURL(string sURL, string sData, string ProxyAddress,
   string ProxyUsername, string ProxyPassword)
  {
   m_httpReq = (HttpWebRequest)WebRequest.Create(sURL);

 

   /**
      * If you are behind a firewall and you do not have your browser proxy setup
      * you need to use the following proxy creation code. */

 

   if ((ProxyAddress != null) && (ProxyAddress != System.String.Empty))
   {
    // Create a proxy object.
    WebProxy myProxy = new WebProxy();

 

    // Associate a new Uri object to the _wProxy object, using the proxy address
    // selected by the user.
    myProxy.Address = new Uri(ProxyAddress);
    if (((ProxyUsername != null) && (ProxyUsername != System.String.Empty))
     && ((ProxyPassword != null) && (ProxyPassword != System.String.Empty)))
     myProxy.Credentials=new NetworkCredential(ProxyUsername, ProxyPassword);
      
    // Finally, initialize the Web request object proxy property with the _wProxy
    // object.
    m_httpReq.Proxy=myProxy;
   }

 

   m_httpReq.Method = "POST";
   m_httpReq.ContentType = "application/x-www-form-urlencoded";
   m_httpReq.ContentLength = sData.Length;

 

   Stream st = m_httpReq.GetRequestStream();

 

   StreamWriter stw = new StreamWriter(st);
   stw.Write(sData);

 

   stw.Flush();
   stw.Close();

 

   IAsyncResult ar = (IAsyncResult) m_httpReq.BeginGetResponse(
    new AsyncCallback(callback), this);

 

   //hold until we are done reading
   //put a timeout here too
   if ((TIME_OUT == 0))
    TIME_OUT = 50000;
   m_bGotResponse = m_eventDone.WaitOne(TIME_OUT,false);
   m_sPost = sData;
   return m_sResp;
  }

 

  public string getPostData()
  {
   return m_sPost;
  }

 

  private void callback(IAsyncResult ar)
  {

 

   HttpWebResponse httpResp = (HttpWebResponse)m_httpReq.EndGetResponse(ar);        

 

   //  Start reading data from the response stream.
   m_stResponse = httpResp.GetResponseStream();

 

   //  Pass rs.BufferRead to BeginRead. Read data into rs.BufferRead
   IAsyncResult iarRead = m_stResponse .BeginRead(m_btRead, 0,
    BUFFER_SIZE, new AsyncCallback(readCallback), this);
  }

 

         
  private void readCallback(IAsyncResult asyncResult)
  {

 

   // Read rs.BufferRead to verify that it contains data.
   int iRead = m_stResponse.EndRead( asyncResult );
   if (iRead > 0)
   {
    // Prepare a Char array buffer for converting to Unicode.
    Char[] charBuffer = new Char[BUFFER_SIZE];
        
    // Convert byte stream to Char array and then to String.
    // len contains the number of characters converted to Unicode.
    int iLen = m_dec.GetChars(m_btRead, 0, BUFFER_SIZE, charBuffer, 0);
    String s = new String(charBuffer, 0, iLen);

 

    // Append the recently read data to the stringbuilder
    m_sbResp.Append(Encoding.ASCII.GetString(m_btRead, 0, iRead));        

 

    // Continue reading data untilm_stResponse.EndRead returns -1.
    IAsyncResult ar = m_stResponse.BeginRead( m_btRead, 0, BUFFER_SIZE,
     new AsyncCallback(readCallback), this);
   }
   else
   {
    if(m_btRead.Length>0)
    {
     //set our response string                 
     m_sResp = m_sbResp.ToString();
    }
    // Close down the response stream.
    m_stResponse.Close();        
    // Set the ManualResetEvent so the main thread can exit.
    m_eventDone.Set();                          
   }
   return;
  }   

 

 }
