How to Use Pre-Signed URL in PHP with Stook

Generate and use pre-signed URLs in PHP for accessing objects in Medianova Stook Object Storage.

You can generate pre-signed URLs with the AWS SDK for PHP to securely access or share objects stored in Medianova Stook Object Storage. Pre-signed URLs allow time-limited access without exposing your credentials.

---

Prerequisites

• PHP installed on your system

• AWS SDK for PHP included in your project

• Medianova Stook credentials (Access Key, Secret Key, Endpoint)

---

Example: Generate a Pre-Signed URL

require 'vendor/autoload.php';

use Aws\S3\S3Client;  
use Aws\S3\Exception\S3Exception;

$bucket = "bucket";  
$key = "mykey";  

// Create a S3Client  
$s3 = new Aws\S3\S3Client([
    'endpoint' => 'https://customername.mncdn.com',
    'profile' => 'medianova',
    'version' => 'latest',
    'region' => 'us-east-1',
    'use_path_style_endpoint' => true
]);

$cmd = $s3->getCommand('GetObject', [
    'Bucket' => $bucket,
    'Key'    => $key,
]);

$request = $s3->createPresignedRequest($cmd, '+20 minutes');  

$presignedUrl = (string) $request->getUri();  
echo $presignedUrl;

How It Works

1. Define your bucket and object key.

2. Create an S3Client with your Stook endpoint and credentials.

3. Use the getCommand method to specify the operation (e.g., GetObject).

4. Generate a pre-signed URL with createPresignedRequest.

5. Share or use the generated URL to access the object for a limited time.

Troubleshooting / FAQ

• Expired URL: Check the validity time (+20 minutes, +1 hour, etc.).

• Access denied: Verify bucket policy and Stook credentials.

• Invalid endpoint: Ensure your Stook endpoint matches your account.
