(JavaScript) S3 Find Bucket Region

Demonstrates how to find out the region of 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 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 using the correct region (in this example, "us-west-2")
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();
authAws.AccessKey = "AWS_ACCESS_KEY";
authAws.SecretKey = "AWS_SECRET_KEY";
authAws.ServiceName = "s3";
success = rest.SetAuthAws(authAws);

// The bucket name we want to know about is set in the HOST header.
// In this example, we want to find the region for the "chilkat.qa" bucket.
rest.Host = "chilkat.qa.s3.amazonaws.com";

// Send the GET request to query the bucket location.
var strResult = rest.FullRequestNoBody("GET","/?location");
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

var responseStatusCode = rest.ResponseStatusCode;
console.log("Response status code = " + responseStatusCode);
if (responseStatusCode !== 200) {
    console.log(rest.ResponseHeader);
    console.log(strResult);
    console.log("Failed.");
    return;
}

console.log(strResult);

// The result contains XML like this:
// <?xml version="1.0" encoding="UTF-8"?>
// <LocationConstraint xmlns="http://s3.amazonaws.com/doc/2006-03-01/">us-west-2</LocationConstraint>

// Get the "us-west-2" from the XML
var xml = new CkXml();
success = xml.LoadXml(strResult);
console.log("region = " + xml.Content);
