(PHP Extension) Azure ServiceBus - Request a Token from ACS

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

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// 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
// 

$http = new CkHttp();
$req = new CkHttpRequest();

// Build the HTTP request...
$req->put_HttpVerb('POST');
$req->put_Path('/WRAPv0.9/');
$req->put_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.
$useTls = true;
// resp is a CkHttpResponse
$resp = $http->SynchronousRequest('your-namespace-sb.accesscontrol.windows.net',443,$useTls,$req);
if ($http->get_LastMethodSuccess() != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

// A successful response will have a status code = 200.
if ($resp->get_StatusCode() != 200) {
    print 'Response Status Code = ' . $resp->get_StatusCode() . "\n";
    print $resp->bodyStr() . "\n";
    print 'Failed.' . "\n";

    exit;
}

// 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:
$accessToken = $resp->urlEncParamValue($resp->bodyStr(),'wrap_access_token');

print 'Your access token is the following param string:' . "\n";
print $accessToken . "\n";
