php – Get file's signed URL from amazon s3 using Filesystem Laravel 5.2

Posted by: admin April 23, 2020 Leave a comment

Questions:

I’m looking for a good solution to get the signed url from amazon s3.

I have a version working with it, but not using laravel:

private function getUrl ()
{
        $distribution = $_SERVER["AWS_CDN_URL"];

        $cf = Amazon::getCFClient();

        $url = $cf->getSignedUrl(array(
            'url'     => $distribution . self::AWS_PATH.rawurlencode($this->fileName),
            'expires' => time() + (session_cache_expire() * 60)));

        return $url;
}

I don’t know if this is the best way to do with laravel, considering it has a entire file system to work…

But if don’t have another way, how do I get the client? Debugging I’ve found an instance of it inside the Filesystem object, but it is protected…

How to&Answers:

In Laravel,

$s3 = \Storage::disk('s3');
$client = $s3->getDriver()->getAdapter()->getClient();
$expiry = "+10 minutes";

$command = $client->getCommand('GetObject', [
    'Bucket' => \Config::get('filesystems.disks.s3.bucket'),
    'Key'    => "file/in/s3/bucket"
]);

$request = $client->createPresignedRequest($command, $expiry);

return (string) $request->getUri();

Make sure you have the AWS for flysystem composer package too (version will vary):

"league/flysystem-aws-s3-v3": "1.0.9"

Answer:

For Laravel 5.5 and up,
you can now use temporary URLs/s3 presigned URL.

use \Storage;

// Make sure you have s3 as your disk driver
$url = Storage::disk('s3')->temporaryUrl(
   'file1.jpg', Carbon::now()->addMinutes(5)
);

This only works for s3 storage driver AFAIK.

Answer:

After lote of bugs, at last, I found the solution of accessing private content of s3 bucket using below code:-

use Storage;
use Config;

$client = Storage::disk('s3')->getDriver()->getAdapter()->getClient();
$bucket = Config::get('filesystems.disks.s3.bucket');

$command = $client->getCommand('GetObject', [
    'Bucket' => $bucket,
    'Key' => '344772707_360.mp4'  // file name in s3 bucket which you want to access
]);

$request = $client->createPresignedRequest($command, '+20 minutes');

// Get the actual presigned-url
echo $presignedUrl = (string)$request->getUri();

Answer:

the above explain answer (@brian_d) is ok, but it takes too much time to generate presigned url. i wasted almost 4-5 days to overcome that. finally following worked for me. Thanks to @Kenth.

use Carbon\Carbon;
use Illuminate\Support\Facades\Storage;

$disk = Storage::disk('s3');
$url = $disk->getAwsTemporaryUrl($disk->getDriver()->getAdapter(), $value, Carbon::now()->addMinutes(5), []);
