S3 List Bucket Objects (Bucket-in-Path)

See more Amazon S3 (new) Examples

Demonstrates how to fetch a list of objects in an S3 bucket, but using the bucket-in-path request format instead of putting the bucket name in the HOST header. Go

    // there are three important changes that need to be made.
