Environment: VS7 C# .NET
I wrote this application to see what the HttpWebRequest and HttpWebResponse classes did. I am not a Web programmer and I’m not that familiar with HTTP or HTML, so I wanted to see what these function do. I’m sure someone else who has a more intimate knowledge of these protocols could do a lot more. I was unsure of what I was seeing, which is why I wrote WebPageGet.
private void GetButtonClick(object sender, System.EventArgs e)
{
HttpWebRequest httpReq;
HttpWebResponse httpResp;
Stream httpStream;
m_results.Text = "";
MessageBeep(100);
try
{
ASCIIEncoding ASCII = new ASCIIEncoding();
byte[] buf = new byte[ 128000 ];
m_header_list.Items.Clear();
httpReq = (HttpWebRequest)WebRequest.Create(m_url.Text);
httpResp = (HttpWebResponse)httpReq.GetResponse();
httpStream = httpResp.GetResponseStream();
int count = httpStream.Read(buf, 0, buf.Length);
httpStream.Close();
string tempstr = ASCII.GetString(buf, 0, count);
ChangeLfToCrLf(ref tempstr);
m_results.Text = tempstr;
for(int i=0; i < httpResp.Headers.Count; ++i)
m_header_list.Items.Add( httpResp.Headers.Keys[i] + " = "
+ httpResp.Headers[i]);
for(int i=0; i< httpResp.Cookies.Count; i++)
m_cookie_list.Items.Add( httpResp.Cookies[i]);
}
catch (Exception except)
{
m_results.Text = "Generic Exception: {0}"
+ except.Message.ToString();
}
MessageBeep(10000);
}
