S3 Download Specific Version of File

See more Amazon S3 Examples

Demonstrates how to download a file from the Amazon S3 service using the versionId query parameter.

Note: This example requires Chilkat v9.5.0.89 or later. (A problem regarding AwsSubResources w/ downloads was fixed shortly after the v9.5.0.88 release.)

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();

  http.awsAccessKey = 'AWS_ACCESS_KEY';
  http.awsSecretKey = 'AWS_SECRET_KEY';
  http.awsRegion = 'us-east-1';
  http.awsEndpoint = 's3.amazonaws.com';
  http.awsSubResources = 'versionId=x8UPzRsgskmbe55lEQvhLi25PQl2lcFH';

  const bucketName = 'chilkat100';
  const objectName = 'frenchUtf8.txt';
  const localFilePath = 'qa_output/frenchUtf8.txt';

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