// We demonstrated how to get an access token for your Azure Key Vault
// in this example: Azure Key Vault Get OAuth2 Access Token using Client Credentials

// However.. starting in Chilkat v9.5.0.96, instead of directly providing Chilkat with the OAuth2 access token,
// you can instead provide the means for Chilkat to automatically get the OAuth2 access token,
// and in addition, Chilkat will automatically re-fetch a new OAuth2 access token as needed, such as shortly 
// prior to or after expiration.

// You do this by setting the AuthToken property to a JSON string that contains the required information.

$json = new CkJsonObject();
$json->UpdateString('client_id','APP_ID');

// The APP_PASSWORD is the "password" returned by the Azure CLI command: az ad sp create-for-rbac --name http://example.com --role Contributor
// See Azure Key Vault Get OAuth2 Access Token using Client Credentials
$json->UpdateString('client_secret','APP_PASSWORD');

// The access token will be for Azure Key Vault operations.
$json->UpdateString('resource','https://vault.azure.net');

// Specify the token endpoint which includes your tenant ID.
$json->UpdateString('token_endpoint','https://login.microsoftonline.com/TENANT_ID/oauth2/token');

$http = new CkHttp();

// Instead of providing an actual access token, we give Chilkat the information that allows it to 
// automatically fetch the access token using the OAuth2 client credentials flow.
$http->put_AuthToken($json->emit());

// Replace key_vault_name with the name of your Azure Key Vault.
$sbResponse = new CkStringBuilder();
$success = $http->QuickGetSb('https://key_vault_name.vault.azure.net/certificates?api-version=7.4',$sbResponse);
if ($success == false) {

    $statusCode = $http->get_LastStatus();
    if ($statusCode == 0) {
        // We did not get a response from the server..
        print $http->lastErrorText() . "\n";
    }
    else {
        // We received a response, but it was an error.
        print 'Error response status code: ' . $statusCode . "\n";
        print 'Error response:' . "\n";
        print $sbResponse->getAsString() . "\n";
    }

    exit;
}

$jsonResp = new CkJsonObject();
