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.)

JavaScript

var success = false;

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var http = new CkHttp();

http.AwsAccessKey = "AWS_ACCESS_KEY";
http.AwsSecretKey = "AWS_SECRET_KEY";
http.AwsRegion = "us-east-1";
http.AwsEndpoint = "s3.amazonaws.com";
http.AwsSubResources = "versionId=x8UPzRsgskmbe55lEQvhLi25PQl2lcFH";

var bucketName = "chilkat100";
var objectName = "frenchUtf8.txt";
var localFilePath = "qa_output/frenchUtf8.txt";
