missing content-length in the Response Headers
Hi, my code is :
$media = MediaPrivate::findOrFail($id);
$path = $media->mediaUrl;
$fullName = $media->mediaName . '.' . $media->mediaExtension;
$fileSize = Storage::disk('local')->size($path);
if (Storage::disk('local')->exists($path)) {
$headers = [
'Content-Disposition' => 'attachment; filename="' . $fullName . '"',
'Content-Length' => $fileSize
];
return response()->download(storage_path("app/$path"), $fullName, $headers);
} else {
abort(404);
}
but missing content-length in the Response Headers and Chrome doesn't show the file size when downloaded. please help me. what is the problem?
response headers:
accept-ranges: bytes
cache-control: public
cache-control: public
content-disposition: attachment; filename="file.rar"
content-encoding: gzip
content-type: application/x-rar

I'm not 100% sure and haven't checked, but surely the download function sets the content length and other headers alone?
Storage also brings a download method: https://laravel.com/docs/10.x/filesystem#downloading-files

@Muetze I added the header to the download similar to the Laravel document. Of course, he did not add content-length in the document. Since it does not be added, I tried to add it myself. But in any case, it is still not added to the output. Is this content-length removed from the header elsewhere?

I have tested it and it works.

@Muetze Thank you for taking the time to solve my problem. I modified my code similarly to yours. This is my code:
public function download($locale, $id)
{
$media = MediaPrivate::findOrFail($id);
$path = $media->mediaUrl;
$fullName = $media->mediaName . '.' . $media->mediaExtension;
if (Storage::disk('local')->exists($path)) {
return Storage::disk('local')->download($path, $fullName);
} else {
abort(404);
}
}
I tested your code and it works fine. But my code still has the same problem. Has Header been affected elsewhere? How can I find this out?
Level 1
@Muetze I found the problem. There is only a problem on the server, the reason for which is the addition of: content-encoding: gzip I looked at the server settings, there is such a rule:
# Don't compress images and other uncompressible content
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png|rar|zip|exe|flv|swf|mov|wma|mp3|mp4|avi|mp?g)$ no-gzip dont-vary
but this rule doesn't affect on laravel download URL. I change my url like this:
https://domain.com/en/download/file.rar?expires=1682540805&id=11&user=1&signature=xxx
And again, g-zip is applied, unfortunately. Only disabling gzip completely solves the problem. Tell me if you have a solution.

Finally, I added php to the no-gzip list and the problem went away. Apparently, Apache does not recognize these as files at all, and PHP recognizes them. And of course, with what I did, gzip is no longer applied to any of the pages that are php, which is bad. I tried to apply this rule only to a specific url that starts with download, But whatever I tried, it didn't work, it was either completely disabled or it worked on all urls.
