(PHP ActiveX) Glacier Download Archive

Demonstrates how to download an Amazon Glacier archive. Downloading a Glacier archive is a two step process. First an archive retrieval job is initiated. After it completes, the job output is downloaded (i.e. the archive contents are downloaded.)

Note: This example requires Chilkat v9.5.0.78 or greater.

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rest')
$rest = new COM("Chilkat.Rest");

// Connect to the Amazon AWS REST server in the desired region.
$bTls = 1;
$port = 443;
$bAutoReconnect = 1;
$success = $rest->Connect('glacier.us-west-2.amazonaws.com',$port,$bTls,$bAutoReconnect);

// Provide AWS credentials.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.AuthAws')

// --------------------------------------------------------------------------
// Note: The above REST connection and setup of the AWS credentials
// can be done once.  After connecting, any number of REST calls can be made.
// The "auto reconnect" property passed to rest.Connect indicates that if
// the connection is lost, a REST method call will automatically reconnect
// if needed.

// 1) Send the HTTPS GET request.
// 2) Get the response body.
// 3) If the response status code indicates success, stream the response body (i.e the archive data) to a file.
// 4) If the response status code indicates an error, get the JSON error response.

// Send the GET request.
