Backblaze S3 List Buckets

Demonstrates how to list Backblaze buckets.

The Chilkat S3 functions in the HTTP class are compatible with the Backblaze service. However, because of some specific issues, Chilkat v9.5.0.89 or later is needed.

  // See Global Unlock Sample for sample code.

  const http = new Http();

  // keyID = Access Key ID or Access Key
  http.awsAccessKey = 'access-key';

  // applicationKey = Secret Access Key or Secret Key
