Magento2 Controllers – How to Get User Information Inside a Controller

controllersmagento2

I create route, and controller for it.
All works fine if i call route like so.

….

return $this->_pageFactory->create();

….

However when I want get user data from Magento\Customer\Model\Session inside controller i get error. I use $om to get data but i don`t know why it crash. I need user session for redirect to login form if user is not logged in.

...
        $om = $context->getObjectManager();
        $this->_customerSession = $om->get('Magento\Customer\Model\Session');
        $this->_resultFactory = $context->getResultFactory();
...

in execute

if ($this->_customerSession->isLoggedIn()) {
    return $this->_pageFactory->create();
}
$redirect = $this->_resultFactory->create(\Magento\Framework\Controller\ResultFactory::TYPE_REDIRECT);
$redirect->setUrl('/customer/account/create/');
return $redirect;

So question is how to redirect customer away from route if its not log in ?

Please use like below in your controller to get customer session.

<?php
/**

 */
namespace Vendor\Module\Controller\Index;

class Custom extends \Magento\Framework\App\Action\Action 
{
    protected $_customerSession;
    
    protected $_customerUrl;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Customer\Model\Session $customerSession,
        \Magento\Customer\Model\Url $customerUrl
    ) {
        $this->_customerSession = $customerSession;
        $this->_customerUrl = $customerUrl;
        parent::__construct($context);
    }

    public function isCustomerLogin()
    {
        return $this->_customerSession->isLoggedIn();
    }

    public function getCustomerLoginUrl() 
    {   
        return $this->_customerUrl->getLoginUrl();
    }
}

Finally, I got another solution. It is adding routes.xml under etc/frontend

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
   <router id="standard">
        <route id="customer" frontName="customer">
            <module name="Namespace_ModuleName" />
        </route>
    </router>
</config>

It will redirect the upgrade abc.com/ccustomer/account/upgrademember to the my custom module's controller UpgradeMember.php

Magento 2.1 – Use urlBuilder->getUrl() in Custom Module Controller

If your controller extend Magento\Framework\App\Action\Action you should follow rules of creation of the controller. So you should implement dependency injection of the parent class constructor (Magento\Framework\App\Action\Action):

/**
 * @param Context $context
 */
public function __construct(Context $context)
{
    parent::__construct($context);
    $this->_objectManager = $context->getObjectManager();
    $this->_eventManager = $context->getEventManager();
    $this->_url = $context->getUrl();
    $this->_actionFlag = $context->getActionFlag();
    $this->_redirect = $context->getRedirect();
    $this->_view = $context->getView();
    $this->messageManager = $context->getMessageManager();
}

Your construct method should look like this after a modifications:

/**
 * @param Context $context
 * @param UrlInterface $urlBuilder
 */
public function __construct(
    Context $context,
    UrlInterface $urlBuilder
) {
    parent::__construct($context);
    $this->urlBuilder = $urlBuilder;
}

NOTE: do not forget to remove old var/generation directory after implementing of modifications, because there are stored the generated files of controllers.
