Getting Customer Session

[licentia]

 Hi Guys,

I've a helper and in the __construct() something like:

    public function __construct(
        Context $context,
        \Magento\Customer\Model\Session $customerSession
    )
    {
        parent::__construct($context);

        $this->_customerSession = $customerSession;
        
    }

The problem is when I can the $_customerSession object data it's empty, even though I've logged in.

 It seems the session is instantiated at a later point in the process, because if I call the customer\Session object in a page Model or block it works fine. In fact, the whole store works as expected. I can see the logged in welcome message in the top right bar, add products to cart, login.

The code above is dispatched in the event 

catalog_product_get_final_price

How do I make sure the session is loaded or how do I know when it's loaded?

Regards

You can use 

\Magento\Framework\App\Http\Context $httpContext

$this->_httpContext->getValue(\Magento\Customer\Model\Context::CONTEXT_AUTH)

to check if a customer is logged in

Hi,

Thanks for your message, but it only gives you the logged  status, and not the customer ID.

add following variable into your class

protected $_customerSession;

on your class constructor

public function __construct(
    \Magento\Customer\Model\Session $customerSession,
) {
    $this->_customerSession = $customerSession;
}

use following code in your function

$customerId = $this->customerSession->getCustomerId();
