(PowerShell) 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.

$rest = New-Object Chilkat.Rest

# Connect to the Amazon AWS REST server in the desired region.
$bTls = $true
$port = 443

# --------------------------------------------------------------------------
# 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.
