Answer 1

You can not call this function from __construct function

Please try:

Note: delete var/generation folder after follow below code

<?php 
namespace Test\Module1\Controller\Index; 

class Index extends \Magento\Framework\App\Action\Action {

    protected $resultPageFactory;
    protected $request;

  public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Framework\App\Request\Http $request,
   \Magento\Framework\View\Result\PageFactory $resultPageFactory)     
    {

        $this->resultPageFactory = $resultPageFactory;
        $this->request = $request;

        parent::__construct($context);
    }

    public function execute()
    {
        $fullActionName= $this->request->getFullActionName(); 
        $resultPage = $this->resultPageFactory->create();
        $resultPage->getConfig()->getTitle()->prepend(__($fullActionName.'test example'));
        return $resultPage;
    }
}
 ?>

Answer 2

public function process(\Magento\Framework\App\RequestInterface $request) {
    if($request->getControllerName() == 'product' && $request->getModuleName() == 'catalog'){
        $request->setModuleName('cms')->setControllerName('page')->setActionName('view')->setParam('page_id', 8);
    }else if($request->getControllerName() == 'category' && $request->getModuleName() == 'catalog'){
        $request->setModuleName('cms')->setControllerName('page')->setActionName('view')->setParam('page_id', 7);
    }else{
        $request->setModuleName('cms')->setControllerName('index')->setActionName('index'); 
    }
}

You just add Request interface \Magento\Framework\App\RequestInterface $request

Answer 3

Just try with this code:

put parent::__construct($context);

above ur code

$request->getFullActionName();

You will get,ur result
