(JavaScript) S3 List Bucket Objects (using Chilkat REST)

Demonstrates how to fetch a list of objects in an S3 bucket.

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;
success = rest.Connect("s3.amazonaws.com",port,bTls,bAutoReconnect);

// ----------------------------------------------------------------------------
// 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.
var authAws = new CkAuthAws();
authAws.AccessKey = "AWS_ACCESS_KEY";
authAws.SecretKey = "AWS_SECRET_KEY";
authAws.ServiceName = "s3";
success = rest.SetAuthAws(authAws);

//  Set the bucket name via the HOST header.
//  In this case, the bucket name is "chilkat100".
rest.Host = "chilkat100.s3.amazonaws.com";

var sbResponse = new CkStringBuilder();

    console.log(rest.LastErrorText);
    return;
}

var statusCode = rest.ResponseStatusCode;
console.log("Response status code = " + statusCode);

var xml = new CkXml();
xml.LoadSb(sbResponse,true);
console.log(xml.GetXml());

if (statusCode !== 200) {
    console.log("Failed.  See error information in the XML.");
