Laravel 5.1 - how to download pdf file from S3 bucket - php

Question

I am using Laravel's Storage facade and I am able to upload the pdf to S3 and I am also able to get() its contents but I cannot display or download it to the end user as an actual pdf file. It just looks like raw data. Here is the code:
$file = Storage::disk($storageLocation)->get($urlToPDF);
header("Content-type: application/pdf");
header("Content-Disposition: attachment; filename='file.pdf'");
echo $file;
How can this be done? I have checked several articles (and SO) and none of them have worked for me.

Answer 1

I think something like this will do the job in L5.2:
public function download($path)
{
$fs = Storage::getDriver();
$stream = $fs->readStream($path);
return \Response::stream(function() use($stream) {
fpassthru($stream);
}, 200, [
"Content-Type" => $fs->getMimetype($path),
"Content-Length" => $fs->getSize($path),
"Content-disposition" => "attachment; filename=\"" .basename($path) . "\"",
]);
}

Answer 2

you can create a download url, using the getObjectUrl method
somthing like this:
$downloadUrl = $s3->getObjectUrl($bucketname, $file, '+5 minutes', array(
'ResponseContentDisposition' => 'attachment; filename=$file,'Content-Type' => 'application/octet-stream',
));
and pass that url to the user. that will direct the user to an amzon page which will start the file download (the link will be valid for 5 minutes - but you can change that)
another option, is first saving that file to your server, and then let the user download the file from your server

Answer 3

You can do with this code (replace with your directory and your file name) ....
Storage::disk('s3')->download('bucket-directory/filename');

Answer 4

If your bucket is private, this is the way to obtain a url to download the file.
$disk = \Storage::disk('s3');
if ($disk->exists($file)) {
$command = $disk->getDriver()->getAdapter()->getClient()->getCommand('GetObject', [
'Bucket' => \Config::get('filesystems.disks.s3.bucket'),
'Key' => $file,
'ResponseContentDisposition' => 'attachment;'
]);
$request = $disk->getDriver()->getAdapter()->getClient()->createPresignedRequest($command, '+5 minutes');
$url = (string)$request->getUri();
return response()->json([
'status' => 'success',
'url' => $url
]);
}

Answer 5

In Laravel 5.7 it can be done with streamDownload:
return response()->streamDownload(function() use ($attachment) {
echo Storage::get($attachment->path);
}, $attachment->name);

Answer 6

$filename = 'test.pdf';
$filePath = storage_path($filename);
$header = [
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'inline; filename="'.$filename.'"'
];
return Response::make(file_get_contents($filePath), 200, $header);

Answer 7

$d = file_full_path_here...
$d = str_replace(' ', '%20', $d); //remove the white space in url
ob_end_clean();
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=" . $d);
header("Content-Type: application/pdf");
return readfile($d);

Answer 8

I figured it out. Silly mistake. I had to remove the single quotes from filename.
Fix:
$file = Storage::disk($storageLocation)->get($urlToPDF);
header("Content-type: application/pdf");
header("Content-Disposition: attachment; filename=file.pdf");
echo $file;
