Magento 2 Plugin After Execute Controller

Question

Existing controller that returns a JSON.

public function execute()
{   

    $customer = $this->_customerModel->getById(175);
    $resultJson = $this->resultFactory->create(\Magento\Framework\Controller\ResultFactory::TYPE_JSON);
    $resultJson->setData(
        [
            'status' => 'ok',
            'message' => 'Success.',
            'data' => $customer->__toArray()
        ]
        );

    return $resultJson;
    
}

I have an afterExecute plugin where I try to get the data of the result

public function afterExecute(TestEndpoint $subject, $result)
{
    $result2 = json_decode($result);
    return $result;
}

There is an error saying thet $result is an Object not a JSON string. I want to get the customer data that was returned in the controller. How do I do that?

Answer 1

In afterExecute $result is a json object if you want to get the data as an array you need to call getData() on $result to retrieve the data setted with setData() in the original function.

Since the value of $result->getData() will be an array you cannot use json_decode but can use json_encode to get the value as a json string.
