Magento 2: Redirect Url with query string parameters

If you want to redirect link with query string parameters using Magento ResultFactory, then you can use below script.

You can make a link with a query string using Magento\Framework\UrlInterface;

Here I have used that in the controller file.

<?php
namespace Vendername\Modulename\Controller\Index;
use Magento\Framework\Controller\ResultFactory;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\App\Request\DataPersistorInterface;
use Magento\Framework\View\Element\Messages;
use Magento\Framework\DataObject;
use Magento\Framework\UrlInterface;

class Post extends Action
{


protected $_inlineTranslation;
protected $_transportBuilder;
protected $_scopeConfig;
protected $_logLoggerInterface;
protected $urlBuilder;
protected $_attributeRepository;

public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\Translate\Inline\StateInterface $inlineTranslation,
\Magento\Framework\Mail\Template\TransportBuilder $transportBuilder,
\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
\Psr\Log\LoggerInterface $loggerInterface,
UrlInterface $urlBuilder,
\Magento\Catalog\Model\Product\Attribute\Repository $AttributeRepository,
array $data = []

)
{
$this->_inlineTranslation = $inlineTranslation;
$this->_transportBuilder = $transportBuilder;
$this->_scopeConfig = $scopeConfig;
$this->_logLoggerInterface = $loggerInterface;
$this->messageManager = $context->getMessageManager();
$this->urlBuilder = $urlBuilder;
$this->_attributeRepository = $AttributeRepository;


parent::__construct($context);


}

public function execute()
{
$argument = array('q' => 'test');
$redirecturl = $this->urlBuilder->getUrl('set-your-redirect-path', ['_current' => true,'_use_rewrite' => true, '_query' => $argument]);
return $this->resultRedirectFactory->create()->setUrl($redirecturl);
}


}

<?php

namespace Vendername\Modulename\Controller\Index;

use Magento\Framework\Controller\ResultFactory;

use Magento\Framework\App\Action\Action;

use Magento\Framework\App\Action\Context;

use Magento\Framework\App\Request\DataPersistorInterface;

use Magento\Framework\View\Element\Messages;

use Magento\Framework\DataObject;

use Magento\Framework\UrlInterface;

class Post extends Action

{

protected $_inlineTranslation;

protected $_transportBuilder;

protected $_scopeConfig;

protected $_logLoggerInterface;

protected $urlBuilder;

protected $_attributeRepository;

public function __construct(

\Magento\Framework\App\Action\Context $context,

\Magento\Framework\Translate\Inline\StateInterface $inlineTranslation,

\Magento\Framework\Mail\Template\TransportBuilder $transportBuilder,

\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,

\Psr\Log\LoggerInterface $loggerInterface,

UrlInterface $urlBuilder,

\Magento\Catalog\Model\Product\Attribute\Repository $AttributeRepository,

array $data = []

)

{

$this->_inlineTranslation = $inlineTranslation;

$this->_transportBuilder = $transportBuilder;

$this->_scopeConfig = $scopeConfig;

$this->_logLoggerInterface = $loggerInterface;

$this->messageManager = $context->getMessageManager();

$this->urlBuilder = $urlBuilder;

$this->_attributeRepository = $AttributeRepository;

parent::__construct($context);

}

public function execute()

{

$argument = array('q' => 'test');

$redirecturl = $this->urlBuilder->getUrl('set-your-redirect-path', ['_current' => true,'_use_rewrite' => true, '_query' => $argument]);

return $this->resultRedirectFactory->create()->setUrl($redirecturl);

}

Note: I have tried this code with Magento 2.3.5 version.
