Magento Not able to locate response class

Question

I am creating a module to capture response on controller_front_send_response_before event.

In my observer file, I am getting both request and response object but I am not able to locate below class of response object:

Magento\Framework\App\Response\Http\Interceptor

I am searching in /magento root/vendor/magento/framework/App directory.

Also, When I was trying to log response, I got only headers in log file. How can I get final content that will print on browser?

In onbserver file I have written following code:

Ktpl\Logresponse\Observer\Response\Capture.php

namespace Ktpl\Logresponse\Observer\Response;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Event\Observer;

class Capture implements ObserverInterface
{
    private $logger;

    public function __construct(\Psr\Log\LoggerInterface $logger) {
        $this->logger = $logger;
    }

    public function execute(Observer $observer) {
        try {
            $response = $observer->getEvent()->getData('response');
            $this->logger->debug($response);
            $this->logger->debug(get_class($response));
        } catch(\Exception $e) {
            $this->logger->critical($e);
        }
    }
}

Please share if anyone has any idea about this.

Answer 1

the class Magento\Framework\App\Response\Http\Interceptor is generated by the ObjectManager.

You can find the class on your Server under var/generation/Magento/Framework/App/Response/Http/Interceptor.php

This class is responsible for executing all Plugins defined for Magento\Framework\App\Response\Http

So the Actual Response Object is still Magento\Framework\App\Response\Http, but the Interceptor class is injected as a wrapper for this.
