I have created custom extension with some library classes. I have placed the libraries in lib/internal/SSOSdk folder. I need to include one of the library class in my controller. I have used the below code but it gives Class not found error.

Here is my code

namespace Company\Sso\Controller\Login;


    class Login extends \Magento\Framework\App\Action\Action
        private $resultPageFactory;

        private $scopeConfig;

        public $storeManager;    

        public function __construct(
            \Magento\Framework\App\Action\Context $context,
            \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
            \Magento\Store\Model\StoreManagerInterface $storeManager,
            \Magento\Framework\View\Result\PageFactory $resultPageFactory
        ) {
            $this->resultPageFactory = $resultPageFactory;
            $this->scopeConfig = $scopeConfig;
            $this->storeManager = $storeManager;

         public function execute()
            $apiUrl = 'test.com';
            $clientId = '123';
            $clientSecret = '456';

            $params = $_GET;

            $sso = new SSO($apiUrl, $clientId, $clientSecret);
            try {
                    $sso->notifyJs(false, $params);
                    $sso->notifyJs(true, $params);                
            } catch (Exception $e) {
                $sso->notifyJs(false, $e);



class SSO {

    private $_clientId, $_clientSecret, $_hostUrl;

    public function __construct($hostUrl, $clientId, $clientSecret){
        $this->_hostUrl = $hostUrl;
        $this->_clientId = $clientId;
        $this->_clientSecret =$clientSecret;

    public function setHostUrl($hostUrl){
        $this->_hostUrl = $hostUrl;


How can I do this?

  • is SSO.php has any class name space? – Amit Bera Jun 7 '19 at 8:37
  • @AmitBera No, I have added the SSO.php code – Jancy Abraham Jun 7 '19 at 8:45
  • A single file right Or your have multi-files on this API – Amit Bera Jun 7 '19 at 8:46
  • @AmitBera Yes, I have multi-files – Jancy Abraham Jun 7 '19 at 8:49
  • You have to convert your class to psr-2 format php-fig.org/psr/psr-2 – Amit Bera Jun 7 '19 at 8:51

try this

require_once(__DIR__ . '../../../../lib/internal/SSOSdk/SSO.php');

instead of



new \SSO

instead of

new SSO

But I suggest converting your classes to psr-2 format php-fig.org/psr/psr-2 right solution.

  • I have only changed the object creation section,ie, use new \SSO instead of new SSO – Jancy Abraham Jun 7 '19 at 10:59
