FR: File Downloads w Dynamically Generated Expiring Links

[Patrick]

Hi,

We’re trying to use Cloudfront to deliver our large file downloads to our members. File sizes run 2GB – 9GB.

S3Bubble *almost* offers what we need and seems just a step away.

Rather than defining a link to share, I’d like to tag an object as ‘shareable’. Then, when I paste the shortcode into WordPress, S3Bubble generates a unique link for every pageview. When someone clicks on the link, it starts the expiry countdown (and is valid for only the period of time we set when tagging an object as ‘sharable’).

Basically – I’d love to replace the plug-in I use for this S3FlowShield (which doesn’t support Cloudfront distributions) with S3Bubble.

Make sense?

Hi Patrick,

I would love that too from S3Bubble, but I currently use S3 Media Vault from DAP/WCP

http://wickedcoolplugins.com/dap/a/?a=11804&p=www.wickedcoolplugins.com/doc/s3mediavault-pro-installation/

That may be an option until it becomes part of S3Bubble someday.

Good luck!

Hi Both,

Actually delivering timed downloads with S3 is an easy call that can be done with the AWS sdk like this.

// Create a presigned url
$request = $s3Client->createPresignedRequest($s3Client->getCommand('GetObject', [
	'Bucket' => 'bucket',
	'Key'    => 'key'
	]), '+5 minutes');
$presignedUrl = (string) $request->getUri();

CloudFront is actually a bit of a pain the called required is like below.

// Create a signed URL for the resource using the canned policy
$signedUrlCannedPolicy = $cloudFront->getSignedUrl([
    'url'         => $streamHostUrl . '/' . $resourceKey,
    'expires'     => $expires,
    'private_key' => '/path/to/your/cloudfront-private-key.pem',
    'key_pair_id' => ''
]);

The difference being you need to add a private_key and key_pair_id then the pem need to be stored somewhere it just creates extra complexities so that’s probably why they don’t offer it the call above just needs two keys from an IAM user.

Some docs: https://docs.aws.amazon.com/aws-sdk-php/v3/guide/service/cloudfront-signed-url.html
