I would like to get a request parameter in the observer file.

Below is the observer code.

etc/frontend/di.xml

<event name="review_save_before">
 <observer name="set_customer_data" instance="NamespaceModulenameObserverReviewSaveBeforeObserver"/>
</event>

Observer/ReviewSaveBeforeObserver

<?php
namespace NamespaceModulenameObserver;

use MagentoFrameworkEventObserver;
use MagentoFrameworkEventObserverInterface;
use MagentoReviewModelReview;
use PsrLogLoggerInterface;
use MagentoSalesApiDataOrderInterface;
use MagentoFrameworkAppRequestHttp;

class ReviewSaveBeforeObserver implements ObserverInterface


 /**
 * @var Http
 */
 private $request;

 /**
 * @var OrderInterface
 */
 private $orderInterface;

 /** @var MagentoFrameworkLoggerMonolog */
 protected $logger;

 public function __construct(
 LoggerInterface $loggerInterface,
 OrderInterface $orderInterface,
 Http $request
 ) 
 $this->logger = $loggerInterface;
 $this->orderInterface = $orderInterface;
 $this->request = $request;
 

 /**
 * This is the method that fires when the event runs.
 *
 * @param Observer $observer
 */
 public function execute(Observer $observer)
 
 $this->logger->addDebug('Executed Review Save After Observer');

 /** @var Review $review */
 $review = $observer->getDataByKey('object');
 echo '<pre>';print_r($this->request->getParams());die;
 //$review->setStatusId(Review::STATUS_APPROVED); 
 $review->setCustomerId(1); 
 

But it is throwing below error.

Fatal error: Uncaught Exception: User Error: Some transactions have not been committed or rolled back in /var/www/html/CE/2.3.0/vendor/magento/framework/DB/Adapter/Pdo/Mysql.php on line 3955 in /var/www/html/CE/2.3.0/vendor/magento/framework/App/ErrorHandler.php:61 Stack trace: #0 [internal function]: MagentoFrameworkAppErrorHandler->handler(256, 'Some transactio...', '/var/www/html/C...', 3955, Array) #1 /var/www/html/CE/2.3.0/vendor/magento/framework/DB/Adapter/Pdo/Mysql.php(3955): trigger_error('Some transactio...', 256) #2 [internal function]: MagentoFrameworkDBAdapterPdoMysql->__destruct() #3 main thrown in /var/www/html/CE/2.3.0/vendor/magento/framework/App/ErrorHandler.php on line 61

Any help would be appreciated! Thanks.

Try using

MagentoFrameworkAppRequestInterface::getParams() 

In replacement for:

MagentoFrameworkAppRequestHttp::getParams()
