Eu criei um módulo mostrado neste post. Mas meu próprio controlador não funciona. Recebi esta mensagem de erro:
Erro recuperável: o argumento 1 passado para MP \ MyModule \ Controller \ Index \ CheckUserName :: __ construct () deve ser uma instância do Magento \ Framework \ App \ Action \ Context, instância do Magento \ Framework \ ObjectManager \ ObjectManager fornecida, chamada em D : \ xampp \ htdocs \ magento2 \ fornecedor \ magento \ framework \ ObjectManager \ Factory \ AbstractFactory.php na linha 97 e definido em D: \ xampp \ htdocs \ magento2 \ app \ código \ mp \ MyModule \ Controller \ Index \ CheckUserName. php na linha 35
Aqui está o código do meu controlador:
<?php
namespace MP\MyModule\Controller\Index;
class CheckUserName extends \Magento\Framework\App\Action\Action
{
protected $_logger;
protected $_objectManager;
protected $_request;
/*
\Psr\Log\LoggerInterface $logger, //log injection
\Magento\Framework\App\Request\Http $request
$this->_logger = $logger;
$this->_logger->debug('CheckUserName_Constructor_Begin');
$this->_request = $request;
$this->_logger->debug('CheckUserName_Constructor_End');
*/
/**
* @var \Magento\Framework\View\Result\PageFactory
*/
protected $resultPageFactory;
/**
* @param \Magento\Framework\App\Action\Context $context
* @param \Magento\Framework\View\Result\PageFactory resultPageFactory
*/
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\View\Result\PageFactory $resultPageFactory
)
{
parent::__construct($context);
$this->resultPageFactory = $resultPageFactory;
}
public function execute()
{
echo "Hello from Checkusername";
}
}
?>
Aqui estão as mensagens de erro após excluir a pasta var / generation:
