This example duplicates the HTTP POST described at Request a Token from ACS.

// This example assumes the Chilkat HTTP API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The goal of this example is to send the following HTTP POST:

// POST https://your-namespace-sb.accesscontrol.windows.net/WRAPv0.9/ HTTP/1.1  
// Content-Type: application/x-www-form-urlencoded  
// Host: your-namespace-sb.accesscontrol.windows.net  
// Content-Length: 136  
// Expect: 100-continue  
// Connection: Keep-Alive  
// 
// wrap_name=owner&wrap_password=r8LuxCKD6DWY8auQcFql4M7euH2UuhcLcV1TaJTqNNE%3d&wrap_scope=http%3a%2f%2fyour-namespace.servicebus.windows.net%2f
// 

Chilkat.Http http = new Chilkat.Http();
Chilkat.HttpRequest req = new Chilkat.HttpRequest();

// Build the HTTP request...
req.HttpVerb = "POST";
req.Path = "/WRAPv0.9/";
req.ContentType = "application/x-www-form-urlencoded";

// Adding the Connection: Keep-Alive is optional.  It only makes sense if the intent is to send
// additional requests to the same domain (your-namespace-sb.accesscontrol.windows.net) within a reasonable time period.
req.AddHeader("Connection","Keep-Alive");

// The Expect: 100-continue really isn't necessary.  This only makes sense when a response is large.  The "100-continue"
// provides a means for the HTTP server to alert the HTTP client that the request failed before sending the full response.
// In this case, the response size is small, so there's no real need to bother with an "Expect: 100-continue".
// If desired, it would be added just like any request header:
req.AddHeader("Expect","100-continue");

// Note: The following headers are automatically added by Chilkat:  Content-Type, Host, Content-Length.
// The application should NOT set these directly.

// Add the query parameters
// When URL decoded and split, the query params look like this:
// 
// 	wrap_name=owner
// 	wrap_password=r8LuxCKD6DWY8auQcFql4M7euH2UuhcLcV1TaJTqNNE=
// 	wrap_scope=http://your-namespace.servicebus.windows.net/

// Pass the URL-decoded values to AddParam.
req.AddParam("wrap_name","owner");
req.AddParam("wrap_password","r8LuxCKD6DWY8auQcFql4M7euH2UuhcLcV1TaJTqNNE=");
req.AddParam("wrap_scope","http://your-namespace.servicebus.windows.net/");

// OK.. our request is properly setup.  Now send to the web server at your-namespace-sb.accesscontrol.windows.net.
// We want https (i.e. SSL/TLS), so the port would be 443.
bool useTls = true;
Chilkat.HttpResponse resp = http.SynchronousRequest("your-namespace-sb.accesscontrol.windows.net",443,useTls,req);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// A successful response will have a status code = 200.
if (resp.StatusCode != 200) {
    Debug.WriteLine("Response Status Code = " + Convert.ToString(resp.StatusCode));
    Debug.WriteLine(resp.BodyStr);
    Debug.WriteLine("Failed.");

    return;
}

// A successful response will contain a URL encoded param string such as the following:

// 	wrap_access_token=net.windows.servicebus.action%3d
// 	Listen%252cManage%252cSend%26
// 	http%253a%252f%252fschemas.microsoft.com%252faccesscontrolservice%252f2010%252f07%252fclaims%252fidentityprovider%3d
// 	https%253a%252f%252fyour-namespace-sb.accesscontrol.windows.net%252f%26
// 	Audience%3dhttp%253a%252f%252fyour-namespace.servicebus.windows.net%252f%26
// 	ExpiresOn%3d1404435127%26
// 	Issuer%3dhttps%253a%252f%252fyour-namespace-sb.accesscontrol.windows.net%252f%26
// 	HMACSHA256%3dF%252bBoXUoifWdT%252fly8Oic9V1oPBbc3KmXKbSJbVhGSopU%253d&
// 	wrap_access_token_expires_in=10799
// 

// The UrlEncParamValue method can be used to extract individual param values by name.
// There are two params in the response: wrap_access_token and wrap_access_token_expires.
// (It's a bit confusing because the value of the wrap_access_token is itself a URL encoded 
// param string.)

// Get the access token from the response:
string accessToken = resp.UrlEncParamValue(resp.BodyStr,"wrap_access_token");

Debug.WriteLine("Your access token is the following param string:");
Debug.WriteLine(accessToken);
