Logging¶

The logger can be injected from the ServerContainer:

<?php
namespace OCA\MyApp\AppInfo;

use \OCP\AppFramework\App;

use \OCA\MyApp\Service\AuthorService;


class Application extends App {

    public function __construct(array $urlParams=array()){
        parent::__construct('myapp', $urlParams);

        $container = $this->getContainer();

        /**
         * Controllers
         */
        $container->registerService('AuthorService', function($c) {
            return new AuthorService(
                $c->query('Logger'),
                $c->query('AppName')
            );
        });

        $container->registerService('Logger', function($c) {
            return $c->query('ServerContainer')->getLogger();
        });
    }
}

and then be used in the following way:

<?php
namespace OCA\MyApp\Service;

use \OCP\ILogger;


class AuthorService {

    private $logger;
    private $appName;

    public function __construct(ILogger $logger, $appName){
        $this->logger = $logger;
        $this->appName = $appName;
    }

    public function log($message) {
        $this->logger->error($message, array('app' => $this->appName));
    }

}
