S3 List Buckets (using Chilkat REST)

Demonstrates how to fetch a list of S3 buckets.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var rest = new CkRest();

// Connect to the Amazon AWS REST server.
var bTls = true;
var port = 443;
var bAutoReconnect = true;

// Important: For buckets created in regions outside us-east-1,
// there are three important changes that need to be made.
// See Working with S3 Buckets in Non-us-east-1 Regions for the details.

// Provide AWS credentials for the REST call.
