Database-Based & Redis-Based Customer-Session Empty Data Issue in Magento 2 Using 2 Web-Servers

Question

I am facing a problem in getting session data in Magento 2, when I deploy my Build on 2 Web-Servers. I am facing no issue on Single Web-Server.

Problem Details I am setting some data in session, in first AJAX request, and then getting that data in the next consecutive AJAX request but the session returns no values.

AJAX-Request Format:

jQuery.ajax({
 url: myUrl,
 type: 'POST',
 dataType: 'json',
 data: myData,
 cache: false,
})

Problem Resolution Approaches

• Printed overall session data and found empty customer data. Only the following data is returned.

  Array([customer_segment_ids] => Array([1] => Array([0] => 3))[wishlist_item_count] => 0)

• Tried to load session data using ObjectManager, while created object of \Magento\Customer\Model\Session and provided the SessionID to get data from the Database-Table using my custom code, but it returned empty array.

• Tried to load session data using MySQL Custom Query by SessionID on that table and got data.

• Changed Session storage to Redis in my app/etc/env.php file, as directed here, but got the same empty session issue.

• Changed Session storage to Files in my app/etc/env.php file and I got the correct data as expected.

Can I have a solution for this problem?

Answer 1

I use the following code to get customer data with the cache enabled which I can achieve by the following code. But you are using the ajax controller request so for you cache will be no problem. kindly share your full code here.

namespace QaisarSatti\Module\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
 protected $objectmanager; 
 public function __construct(
 \Magento\Framework\ObjectManagerInterface $objectmanager
 ) {
 $this->objectmanager = $objectmanager;
 }
 public function getCustomerData()
 {
 $customerSession = $this->objectmanager->create('Magento\Customer\Model\SessionFactory')->create();
 return $customerSession;
 }
}

Reference

• Jehangir Wahid: Thank you for your consideration, There is nothing special about my code, I used the conventional way to get data from the Customer-Session, as follows; namespace MyNamespace\MyModule\Controller\Area; use Magento\Customer\Model\Session; class MyController extends \Magento\Framework\App\Action\Action { protected $_customerCollection; public function __construct(Session $customerSession) { $this->_customerSession = $customerSession; } public function execute() { $myData = $this->_customerSession->getMyCustomData(); } }
• Qaisar Satti: @JehangirWahid if you want to get customer attribute then load through the model. follow blog.qaisarsatti.com/magento_2/magento2-load-customer-by-id
• Jehangir Wahid: No Sir, I am not trying to get Customer Attributes. I am setting some custom data in session the first client request, and then am trying to get that data in the next consecutive request.
• Qaisar Satti: Can you share code where you set the session?
• Jehangir Wahid: Yes, for sure. namespace MyNamespace\MyModule\Controller\Area; use Magento\Customer\Model\Session; class MyController extends \Magento\Framework\App\Action\Action { protected $_customerCollection; public function __construct(Session $customerSession) { $this->_customerSession = $customerSession; } public function execute() { // $myData is an array $this->_customerSession->setMyCustomData($myData); } }
