How to Use Pre-Signed URL in Node.js with Stook

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

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

---

Prerequisites

• Node.js installed on your system

• AWS SDK for Node.js installed (npm install aws-sdk)

• Medianova Stook credentials:

  • Access Key

  • Secret Key

  • Endpoint

---

Example: Generate a Pre-Signed URL

var AWS = require('aws-sdk');

var config = {
    s3ForcePathStyle: true,
};

var credentials = new AWS.SharedIniFileCredentials({
    profile: 'medianova'
});

AWS.config.credentials = credentials;
AWS.config.update(config);

var ep = new AWS.Endpoint('customername.mncdn.com');
var s3 = new AWS.S3({endpoint: ep});

var myBucket = 'bucket';
var myKey = 'mykey';
var signedUrlExpireSeconds = 60 * 5;

var url = s3.getSignedUrl('getObject', {
    Bucket: myBucket,
    Key: myKey,
    Expires: signedUrlExpireSeconds
});

console.log(url);

How It Works

1. Configure the AWS SDK with s3ForcePathStyle.

2. Use your Medianova credentials (via profile or direct configuration).

3. Define bucket, object key, and expiration time.

4. Call getSignedUrl('getObject', {...}) to generate a URL.

5. Use or share the generated URL within its expiration time.

Troubleshooting / FAQ

• Expired URL: Adjust Expires value (e.g., 60*10 for 10 minutes).

• Access denied: Verify bucket policy and Stook credentials.

• Invalid endpoint: Ensure endpoint matches your Stook account.
