[FIXED] when BinaryFileResponse is used file checksum changes

Issue

I used BinaryFileResponse class to create download file response. file is a zip file. file checksum is different after file being downloaded. why this happens and can we send the original file as response.

$response = new BinaryFileResponse($filePath);

$response->headers->set('Content-Type', 'application/octet-stream');
$response->setContentDisposition(
    ResponseHeaderBag::DISPOSITION_ATTACHMENT,
    $fileName
);

return $response->send();

Solution

If you are in a controller, ->send() is not needed ...

Your code should be ...

<?php

class MyController 
{
    public function action()
    {
        $response = new BinaryFileResponse($filePath);

        $response->headers->set('Content-Type', 'application/octet-stream');
        $response->setContentDisposition(
            ResponseHeaderBag::DISPOSITION_ATTACHMENT,
            $fileName
        );

        return $response;
    }
}
