(AutoIt) 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.

$oRest = ObjCreate("Chilkat.Rest")

; Connect to the Amazon AWS REST server in the desired region.
Local $bTls = True
Local $iPort = 443
Local $bAutoReconnect = True
Local $bSuccess = $oRest.Connect("glacier.us-west-2.amazonaws.com",$iPort,$bTls,$bAutoReconnect)

; Provide AWS credentials.
$oAuthAws = ObjCreate("Chilkat.AuthAws")
$oAuthAws.AccessKey = "AWS_ACCESS_KEY"
$oAuthAws.SecretKey = "AWS_SECRET_KEY"

$bSuccess = $oRest.SetAuthAws($oAuthAws)

; --------------------------------------------------------------------------
; 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.

; To download an archive, we'll make several method calls:
; 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.
