Magento 2 logout using curl

Question

As per my requirement i want to logout the customer using PHP curl.

for that I used the following code in my custom controller action(execute)

$lastCustomerId = $this->_customerSession->getId();
$this->_customerSession->logout()->setBeforeAuthUrl($this->_redirect->getRefererUrl())
            ->setLastCustomerId($lastCustomerId);
$value = $this->getCookieManager()->getCookie('mage-cache-sessid');

if ($this->getCookieManager()->getCookie('mage-cache-sessid')) {
   $metadata = $this->getCookieMetadataFactory()->createCookieMetadata();
   $metadata->setPath('/');
   $this->getCookieManager()->deleteCookie('mage-cache-sessid', $metadata);
}

Then in my localhost i created curl.php with the following code

$logoutUrl = 'http://127.0.0.1/Magento2/frontendname/controllername/actionname';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $logoutUrl);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);
$curl_errno = curl_errno($ch);
if($curl_errno){
    echo $curl_errno.'--in error'; exit;
}
print_r($result);
curl_close($ch);

When i run the curl file, it has hit the above logout page but the customer is not logout, but if i run the url directly on the browser the customer has logout.

Also tried this in controller

$pin = 'hitesh_12345678';
$customerData = $this->_customer->getCollection()->addAttributeToFilter('pin', array('eq' => $pin))->getFirstItem();
$customerId = $customerData->getData('entity_id');
if($this->_customerSession->getId() == $customerId)
{
    $this->_customerSession->logout();
    echo 'Customer logout successfully!'; exit;
} else {
    echo "Customer is not login"; exit;
}

But none of the logout functionality is not working.

share your thoughts and ideas for logout using CURL functionality.

Thanks in advance for your better idea and support

If you want to perform some action before logout then Create an observer before customer logout:

event:  customer_logout

In your custom module create

app/code/Vendorname/Modulename/etc/frontend/events.xml

Then create your observer in

VendornameModulename\Observer\Frontend\CustomerLogOutObserver.php

namespace Vendorname\Modulename\Observer\Frontend;
use Magento\Framework\Event\Observer as EventObserver;
use Magento\Framework\Event\ObserverInterface;

class CustomerLogOutObserver implements ObserverInterface
{

    public function execute(EventObserver $observer)
    {
        //do stuff here
    }
}

check:

app/code/Magento/Customer/Controller/Account/Logout.php

/**
 * Customer logout action
 *
 * @return \Magento\Framework\Controller\Result\Redirect
 */
public function execute()
{
    $lastCustomerId = $this->session->getId();
    $this->session->logout()->setBeforeAuthUrl($this->_redirect->getRefererUrl())
        ->setLastCustomerId($lastCustomerId);
 ....

Then app/code/Magento/Customer/Model/Session.php

/**
 * Logout customer
 *
 * @api
 * @return $this
 */
public function logout()
{
    if ($this->isLoggedIn()) {
        $this->_eventManager->dispatch('customer_logout', ['customer' => $this->getCustomer()]);
        $this->_logout();
....
