Backblaze S3 Download File

See more Backblaze S3 Examples

Demonstrates how to download a file from a Backblaze bucket.

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.

React Native

import { Http } 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 http = new Http();

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

  // applicationKey = Secret Access Key or Secret Key
  http.awsSecretKey = 'secret-key';

  // Region is the 2nd part of your S3 Endpoint
  http.awsEndpoint = 's3.us-west-002.backblazeb2.com';

  const bucketName = 'chilkat-test';
  const objectName = 'seahorse.jpg';
  const localFilePath = 'qa_output/seahorse.jpg';

  try {
    await http.s3DownloadFileAsync(bucketName, objectName, localFilePath);
    console.log('File downloaded.');
  } catch {
    console.log(http.lastErrorText);
  }
