S3 Find Bucket Region

See more Amazon S3 (new) Examples

Demonstrates how to find out the region of an S3 bucket. React Native

import { AuthAws, Rest, Xml } from '@chilkat/react-native'

async function chilkatExample() {
  // This requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const rest = new Rest();

  // Connect to the Amazon AWS REST server using the correct region (in this example, "us-west-2")
  const bTls = true;
  const port = 443;
  const bAutoReconnect = true;
  await rest.connectAsync('s3.amazonaws.com', port, bTls, bAutoReconnect);

  // Provide AWS credentials for the REST call.
  const authAws = new AuthAws();
  authAws.accessKey = 'AWS_ACCESS_KEY';
  authAws.secretKey = 'AWS_SECRET_KEY';
  authAws.serviceName = 's3';
  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.
  let strResult: string;
  try {
    strResult = await rest.fullRequestNoBodyAsync('GET', '/?location');
  } catch {
    console.log(rest.lastErrorText);
    return;
  }

  const 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
  const xml = new Xml();
  xml.loadXml(strResult);
  console.log(`region = ${xml.content}`);
