use Envoyr\NginxConfigurator\Node\Directive;
use Envoyr\NginxConfigurator\Node\Literal;
use Envoyr\NginxConfigurator\Node\Param;

require __DIR__ . '/../vendor/autoload.php';

$factory = new Factory()
$builder = new Builder();

$server = $builder->append($factory->createServer(80));
$server->append(new Directive('error_log', [
    new Param('/var/log/nginx/error.log'), 
    new Param('debug'),
]));
$server->append(new Location(new Param('/test'), null, [
    new Directive('error_page', [new Param('401'), new Param('@unauthorized')]),
    new Directive('set', [new Param('$auth_user'), new Literal('none')]),
    new Directive('auth_request', [new Param('/auth')]),
    new Directive('proxy_pass', [new Param('http://test-service')]),
]));
$server->append(new Location(new Param('/auth'), null, [
    new Directive('proxy_pass', [new Param('http://auth-service:9999')]),
    new Directive('proxy_bind', [new Param('$server_addr')]),
    new Directive('proxy_redirect', [new Param('http://$host'), new Param('https://$host')]),
    new Directive('proxy_set_header', [new Param('Content-Length'), new Literal("")]),
    new Directive('proxy_pass_request_body', [new Param('off')]),
