How to download a file programmatically in Magento 2?

Today we are going to explain how to download the file programmatically in Magento 2.

Here we have added controller through which we can download image based on the click or call directly.

namespace Magemonkeys\Download\Controller\Index;

use Magento\Framework\App\Filesystem\DirectoryList;

class Image extends \Magento\Framework\App\Action\Action
{
    protected $fileFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\App\Response\Http\FileFactory $fileFactory
    ) {
        $this->fileFactory = $fileFactory;
        parent::__construct($context);
    }

    public function execute()
    {
        $mediafilePath = 'media/download/homeimage.jpg';
        $downloadFilenm = 'homeimage.jpg';
        $imagearr['type'] = 'mediafilePath';
        $imagearr['value'] = $filePath;
        $imagearr['rm'] = 0;
        return $this->fileFactory->create($downloadFilenm, $imagearr, DirectoryList::PUB);
    }
}

namespace Magemonkeys\Download\Controller\Index;

use Magento\Framework\App\Filesystem\DirectoryList;

class Image extends \Magento\Framework\App\Action\Action

{

protected $fileFactory;

public function __construct(

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

\Magento\Framework\App\Response\Http\FileFactory $fileFactory

) {

$this->fileFactory = $fileFactory;

parent::__construct($context);

}

public function execute()

{

$mediafilePath = 'media/download/homeimage.jpg';

$downloadFilenm = 'homeimage.jpg';

$imagearr['type'] = 'mediafilePath';

$imagearr['value'] = $filePath;

$imagearr['rm'] = 0;

return $this->fileFactory->create($downloadFilenm, $imagearr, DirectoryList::PUB);

}

We can add our logic in execute() method which will help us to download homeimage.jpg by calling this action.
