since openhab 3.0 you can create a token to access the rest api. You can create it in the web interface of openhab

config file (default=openhab.php) instead of the controller parameters -H, -P, -s, -T (you can specify any file with path)
example:

<?php
$host='192.168.2.216'; # IP or Hostname Openhab Server
$port='8080'; # Openhab Port
$prot='http'; # Value http or https
$token='' # Token
$user='' # User
$password='' # Password
?>
