Enabling CORS on an S3 Bucket in AWS (The Hands-on Demo) | Amazon Web Services Tutorial

In a previous video (   • CORS and S3 Simply Explained (The The...  ) we saw the theory behind cross-origin resource sharing (CORS) and how it works with Amazon S3 buckets. In this video, we put that theory into action in the AWS Console. In a hands-on demo, we’ll create two S3 buckets (enabling static website hosting and opening up public access). Then we upload two HTML files to the origin bucket, showing that it works. Next, we split the HTML files across the two buckets (one in the origin bucket and one in the cross-domain bucket) and see that we get a CORS error. “Fetch blocked by CORS policy.” “No Access-Control-Allow-Origin header is present.” Doh! To fix the error, we enable CORS on the cross-origin bucket, allowing GET method requests from the origin bucket.
