Simple HTTP Post with Form Parameters

Download: Chilkat .NET Assemblies

This example demonstrates a simple HTTP POST that sends form parameters.

Chilkat.Http http = new Chilkat.Http();
bool unlocked = http.UnlockComponent("Any string begins 30-day trial");
if (!unlocked)
{
    MessageBox.Show("Failed to unlock HTTP component");
    return;
}

// Sends a POST to http://www.chilkatsoft.com/formTarget.asp, which is a URL you can use
// for testing.  The formTarget.asp file contains this:
/*
<html>
<body>
Hi, <%=Request.Form("firstname")%>. 
Your favorite color is <%=Request.Form("color")%>.
</body>
</html>
*/

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.UsePost();
req.Path = "/formTarget.asp";
req.AddParam("firstname","Matthew");
req.AddParam("color","Blue");

bool ssl = false;   // Set this to true to use HTTPS
Chilkat.HttpResponse resp = http.SynchronousRequest("www.chilkatsoft.com",80,false,req);
if (resp == null) 
{
    MessageBox.Show(http.LastErrorText);
    return;
}

// Did we get a successful response?
if (resp.StatusCode == 200)
{
    // Display the HTML source we received.
    MessageBox.Show(resp.BodyStr);		    
}
else
{
    // Show the full response header...
    MessageBox.Show(resp.Header);
}
