# Demonstrates how to use older AWS S3 Signature Version 2 for uploading the contents
# of a string variable to an object in a bucket.

# 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.
$bTls = $true
$port = 443
$bAutoReconnect = $true
# The file is uploaded to the bucket named "chilkat100", which becomes part of the domain:
$success = $rest.Connect("chilkat100.s3.amazonaws.com",$port,$bTls,$bAutoReconnect)

# ----------------------------------------------------------------------------
# Important: For buckets created in regions outside us-east-1,
# there are three important changes that need to be made.
# See Working with S3 Buckets in Non-us-east-1 Regions for the details.

# Provide AWS credentials for the REST call.

# For AWS Signature Version 2, the following two properties need to be set:
$authAws.SignatureVersion = 2
# See http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html#ConstructingTheCanonicalizedResourceElement
# The bucket is "chilkat100", and the uriPath is "/hamlet_play.xml", which must match
# the URI path passed to the FullRequestString method below.
$authAws.CanonicalizedResourceV2 = "/chilkat100/hamlet_play.xml"

$success = $rest.SetAuthAws($authAws)

# Load a text file into memory.

# header to "gzip" or "deflate".  (this is optional)

# Indicate the Content-Type of our upload.  (This is optional)
$success = $rest.AddHeader("Content-Type","text/xml")

# We can add an "Expect: 100-continue" header so that if the request is rejected
# by the server immediately after receiving the request header, it can respond
# and the client (Chilkat) can avoid sending the file data.
# (this is optional)
$success = $rest.AddHeader("Expect","100-continue")

# Upload the file to Amazon S3.
