(JavaScript) S3 List Buckets using an STS Session Token

This is an example showing how to use an STS session token in an Amazon AWS request. This example will list S3 buckets using a previously obtained session token.

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.

// See Get AWS STS Session Token for sample code to get the session token XML.
var xmlToken = new CkXml();
success = xmlToken.LoadXmlFile("qa_data/tokens/aws_session_token.xml");
if (success == false) {
    console.log(xmlToken.LastErrorText);
    return;
}

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);

// Provide AWS credentials for the REST call.
var authAws = new CkAuthAws();

// The purpose of this example is to show how to use the temporary AccessKeyId, SecretAccessKey, and SessionToken.
authAws.AccessKey = xmlToken.GetChildContent("GetSessionTokenResult|Credentials|AccessKeyId");
authAws.SecretKey = xmlToken.GetChildContent("GetSessionTokenResult|Credentials|SecretAccessKey");
authAws.ServiceName = "s3";
success = rest.SetAuthAws(authAws);

rest.AddQueryParam("X-Amz-Security-Token",xmlToken.GetChildContent("GetSessionTokenResult|Credentials|SessionToken"));

var sbResponse = new CkStringBuilder();
success = rest.FullRequestNoBodySb("GET","/",sbResponse);
if (success !== true) {
    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.");
    return;
}
