Presign URLs

You may "presign" all requests with the $client->presign() function. It will return a URL that is safe to share to anyone. The URL contains encrypted authentication parameters.

This feature can be used if you want to give a user access to a file on S3 but only for a limited time.

use AsyncAws\S3\Input\GetObjectRequest; use AsyncAws\S3\S3Client; $s3 = new S3Client(); $input = new GetObjectRequest([ 'Bucket' => 'my-bucket', 'Key' => 'test', ]); $url = $s3->presign($input, new \DateTimeImmutable('+60 min')); echo $url;

Note: AWS has limitations on the expiration length. Read more in the docs.
