Принудительная загрузка файла, прочитанного Flysystem из AWS S3
Доброе утро всем,
Мой вопрос прост: я использую Flysystem (на Symfony) для восстановления ресурса из S3 (через DigitalOcean). Я хотел бы иметь возможность вернуть его для загрузки пользователю. Вот мой код:
$client = new S3Client([
'credentials' => [
'key' => '',
'secret' => '',
],
'region' => '',
'version' => 'latest',
'endpoint' => 'https://ams3.digitaloceanspaces.com',
]);
$adapter = new AwsS3Adapter($client, '');
$filesystem = new Filesystem($adapter);
$filename = 'file.png';
$stream = $filesystem->readStream('file.png');
$contents = stream_get_contents($stream);
fclose($stream);
$response = new Response($stream);
$disposition = $response->headers->makeDisposition(
ResponseHeaderBag::DISPOSITION_ATTACHMENT,
$filename
);
$response->headers->set('Content-Disposition', $disposition);
return $response;
=> Файл поврежден...
Есть идеи? Большое спасибо за вашу помощь. Гийом
ОБНОВЛЕНИЕ Когда я проверяю текстовый файл, я получаю содержимое моего файла, но с заголовком:
HTTP/1.1 200 OK
Date: Thu, 27 Sep 2018 06:59:35 GMT
Server: Apache/2.4.29 (Ubuntu)
Vary: Authorization,Accept-Encoding
Cache-Control: no-cache, private
Content-Disposition: attachment; filename=toto.png
Link: <http://localhost/api/public/api/docs.jsonld>; rel="http://www.w3.org/ns/hydra/core#apiDocumentation"
Content-Length: 517
Content-Type: text/html; charset=UTF-8
Любые идеи, чтобы загрузить только содержимое файла, и для всех типов файлов? Большое спасибо за все, Гийом

Я знаю, что это несколько лет, но, надеюсь, это кому-то поможет. Я могу форсировать загрузку, но обратите внимание, что я использую Flysystem для прямого доступа к файлу из AWS S3.
$client = new S3Client([
'credentials' => [
'key' => '',
'secret' => '',
],
'region' => '',
'version' => 'latest'
]);
$adapter = new League\Flysystem\AwsS3V3\AwsS3V3Adapter($client, 'bucket-name');
$filesystem = new League\Flysystem\Filesystem($adapter);
try {
$listing = $filesystem->listContents('name-of-folder-in-bucket/', false);
foreach ($listing as $item) {
$path = $item->path();
if ($item instanceof FileAttributes) {
// handle the file
try {
$response = $filesystem->readStream($path);
$fileName = explode("/", $path);
$fileSize = $filesystem->fileSize($path);
$mimeType = $filesystem->mimeType($path);
$fileExtension = mimeToExtension($mimeType);
header("Pragma: public");
header("Expires: -1");
header("Cache-Control: public, must-revalidate, post-check=0, pre-check=0");
header("Content-Transfer-Encoding: binary");
header("Content-Type:application/" . $fileExtension);
header('Content-Disposition: attachment; filename="' . $fileName[1] . '"');
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-Length: ' . $fileSize);
header('Accept-Ranges: bytes');
fpassthru($response);
} catch (FilesystemException | UnableToRetrieveMetadata $exception) {
echo "couldnt retrieve file metadata";
}
} elseif ($item instanceof DirectoryAttributes) {
// handle the directory
}
}
} catch (FilesystemException $exception) {
// handle the error
echo "folder does not exist";
}
А вот код функции mimeToExtension, взятый из этого комментария :
function mimeToExtension($mimeType)
