how to use require_once in magento 2 - php

Question

I'm trying to include a PHP class in magento 2.
I use a require_once and create a folder lib in the root of my module and there I put the folder that contains the class 'lib / Meli / Meli.php'
Also try in the project folder 'lib / lib_web / Meli / Meli.php'
All without success, any suggestion
This is my controller 'Controller / Adminhtml / Action / publicar.php'
<?php
namespace Uno\MercadoLibre\Controller\Adminhtml\Action;
use \Magento\Backend\App\Action;
class publicar extends Action {
protected $_session;
protected $_filesystem;
protected $_directoryList;
/**
* #param Action\Context $context
*/
public function __construct(
Action\Context $context,
\Magento\Framework\Filesystem\DirectoryList $directoryList,
\Magento\Framework\Filesystem $filesystem,
\Magento\Customer\Model\Session $session
) {
parent::__construct($context);
$this->_directoryList = $directoryList;
$this->_filesystem = $filesystem;
$this->_session = $session;
}
/**
* {#inheritdoc}
*/
protected function _isAllowed() {
return $this->_authorization->isAllowed('Uno_MercadoLibre::action_publicar');
}
/**
* Publicar action
*
* #return \Magento\Framework\Controller\ResultInterface
*/
public function execute() {
$appId = '123';
$secretKey = 'abcdefghijkl';
$redirectURI = 'https://example.mx';
$siteId = 'MLM';
//$path = $this->_directoryList->getPath('lib_web');
//echo "PATH " . $path.'/Meli/Meli.php';
//require_once($path.'/Meli/Meli.php');
//$libPath = $this->_filesystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::LIB)->getAbsolutePath();
$mediapath = $this->_filesystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::APP)->getAbsolutePath();
$modulePath = $mediapath.'code/Uno/MecadoLibre/lib/Meli/Meli.php';
echo $modulePath;
require_once($modulePath);
$meli = new Meli($appId, $secretKey);
$params = array();
$url = '/sites/' . $siteId;
$result = $meli->get($url, $params);
echo '<pre>';
print_r($result);
echo '</pre>';
die();
}
}
?>
the path of the class returns to me, but it does not help me for the require_once
/var/inetpub/example.mx/app/code/Uno/MecadoLibre/lib/Meli/Meli.php

Answer 2

Thank you, your information, I told you how I resolved this.
In my class Meli.php add:
namespace Uno\MercadoLibre\Controller\Adminhtml\Action;
In my controller add:
use \Uno\MercadoLibre\Lib\Meli\Meli;
Object Manager
$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $ml_session = $ objectManager->create('\Uno\MercadoLibre\Lib\Meli\Meli', ['client_id' => $ appId, 'client_secret' => $ secretKey, 'access_token' => $ accessToken]);
