(PHP Extension) Azure REST API Access Token

Demonstrates how to request an Azure REST API OAUTH2 access token.

Note: In order to access resources a Service Principal needs to be created in your Tenant. It is really convenient to do it via AZ CLI:

az ad sp create-for-rbac --name [APP_NAME] --password [CLIENT_SECRET]

<?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 requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$rest = new CkRest();

// URL: https://login.microsoftonline.com/TENANT_ID/oauth2/token
$bTls = true;

if ($success != true) {
    print 'ConnectFailReason: ' . $rest->get_ConnectFailReason() . "\n";
    print $rest->lastErrorText() . "\n";
    exit;

// Add query params to the request.

}

$json = new CkJsonObject();
$json->Load($strResponseBody);
$json->put_EmitCompact(false);
print $json->emit() . "\n";

// The result is an access token such as the following:

// {
//   "token_type": "Bearer",
//   "expires_in": "3600",
//   "ext_expires_in": "3600",
//   "expires_on": "1557864616",

//   "resource": "https://management.azure.com/",
//   "access_token": "eyJ0eXAiOiJKV1QiL ... 20UFDDOHEyUg"
// }

// We'll save this JSON to a file for other examples to use..
