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

Question

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...

Answer 1

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"

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 3

After lot 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 4

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), []);

Here is a full code to upload image to S3 and create signed URL;

First, get a file object and create object name

$filename = $_FILES["image"]["name"];
$array = explode('.', $filename);
$fileExt = $array[1]; // to get file extension
$objectName = 'images/' . time() .$fileExt; // create object name
$document = fopen($_FILES["image"]["tmp_name"],'r');

// Code to upload document on s3
$s3 = \Storage::disk('s3');
$s3->put($objectName,$document,'public');

// If you want to get uploaded document Url you can use below code:
$image_name = \Storage::disk('s3')->url($name); // it will return stored document url

Code to create/get signed URL, you can put it as a saperate function also:

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

$command = $client->getCommand('GetObject', [
  'Bucket' => config('params.YOUR_AWS_BUCKET_NAME'), // bucket name
  'Key'    => $objectName
]);

$request = $client->createPresignedRequest($command, $expiry);
$url =  (string) $request->getUri(); // it will return signed URL
