Code example on how to use a presigned URL

[Erikvv]

Background: when making a website with a PHP backend you may not want to pass all traffic to Storj through the PHP backend for cost/performance reasons.

In that case you can use an S3 pre-signed URL to upload or download from the browser to Gateway-MT.

We should have full code examples which demonstrate upload and download like this in https://github.com/storj-thirdparty/uplink-php/tree/main/examples

Roughly it would be

1. Get (expiring) S3 credentials with

   uplink-php/src/Edge/Edge.php

   Line 38 in d2eab1b

   public function registerAccess(

2. Use credentials to create presigned url like https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/s3-presigned-url.html
3. Upload or download via html, redirect or javascript https://stackoverflow.com/questions/39536487/s3-upload-image-with-pre-signed-url-from-browser
