Laravel s3 upload file with metadata using pre-signed url - php

Question

I am implementing S3 file uploads and downloads using pre-signed urls. I have one s3 bucket (versioning enabled) and one AWS user but I want to track the history of each file in terms of which of my application users modified the file.
I have a versioned S3 bucket and my thought is that I can append metadata to every file to identify my application user and possibly other data too.
Here is my code:
public function presignedUpload(Request $request)
{
$this->validate($request, [
'name' => 'string|required'
]);
$s3 = Storage::disk('s3');
$client = $s3->getDriver()->getAdapter()->getClient();
$expiry = "+10 minutes";
$options = ['user-data' => 'user-meta-value'];
$cmd = $client->getCommand('PutObject', [
'Bucket' => \Config::get('filesystems.disks.s3.bucket'),
'Key' => 'path/to/file/' . $request->name,
'ACL' => 'public-read',
], $options);
$request = $client->createPresignedRequest($cmd, $expiry);
$presignedUrl = (string)$request->getUri();
return response()->json(['url' => $presignedUrl], 201);
}
I deduced that I can pass an $options array from the FilesystemAdapter::class. This code does upload the file, but the metadata in AWS looks empty.
Is my $options array in the wrong format?
Appreciate any help on this.

The selected answer doesn't work anymore after Laravel 9. Flysystem recommends you to use S3 SDK instead of Storage driver.

Use the S3 SDK instead to create a resigned upload URL.
$uploadDisk = 's3';
$s3Client = new S3Client([
'credentials' => [
'key' => config('filesystems.disks.' . $uploadDisk . '.key'),
'secret' => config('filesystems.disks.' . $uploadDisk . '.secret'),
],
'region' => config('filesystems.disks.' . $uploadDisk . '.region'),
'version' => 'latest',
]);
$s3Bucket = config('filesystems.disks.' . $uploadDisk . '.bucket');
$s3Key = \Illuminate\Support\Str::uuid(); // your file name
$s3Options = [];
$command = $s3Client->getCommand('PutObject', [
'Bucket' => $s3Bucket,
'Key' => $s3Key,
'MetaData' => $s3Options,
]);
$request = $s3Client->createPresignedRequest($command, '+20 minutes');
$url = (string) $request->getUri();

Metadata can be uploaded like this:
public function presignedUpload(Request $request)
{
$this->validate($request, [
'name' => 'string|required'
]);
$s3 = Storage::disk('s3');
$client = $s3->getDriver()->getAdapter()->getClient();
$expiry = "+10 minutes";
$options = ['user-data' => 'user-meta-value'];
$cmd = $client->getCommand('PutObject', [
'Bucket' => \Config::get('filesystems.disks.s3.bucket'),
'Key' => 'path/to/file/' . $request->name,
'ACL' => 'public-read',
'Metadata' => $options,
]);
$request = $client->createPresignedRequest($cmd, $expiry);
$presignedUrl = (string)$request->getUri();
return response()->json(['url' => $presignedUrl], 201);
}
