S3 Upload String using AWS Signature Version 2

See more Amazon S3 (new) Examples

Example to upload the contents of a string to the Amazon S3 service, using the older AWS Signature Version 2. AutoIt

Local $bSuccess = False

; 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.

$oRest = ObjCreate("Chilkat.Rest")

; Connect to the Amazon AWS REST server.
Local $bTls = True
Local $iPort = 443
Local $bAutoReconnect = True
; The file is uploaded to the bucket named "chilkat100", which becomes part of the domain:
$bSuccess = $oRest.Connect("chilkat100.s3.amazonaws.com",$iPort,$bTls,$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.
$oAuthAws = ObjCreate("Chilkat.AuthAws")
$oAuthAws.AccessKey = "AWS_ACCESS_KEY"
$oAuthAws.SecretKey = "AWS_SECRET_KEY"
$oAuthAws.ServiceName = "s3"

; For AWS Signature Version 2, the following two properties need to be set:
$oAuthAws.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.
$oAuthAws.CanonicalizedResourceV2 = "/chilkat100/hamlet_play.xml"

$bSuccess = $oRest.SetAuthAws($oAuthAws)

; Load a text file into memory.

; To send the file in gzip or deflate compressed format, set the Content-Encoding request
; header to "gzip" or "deflate".  (this is optional)
$bSuccess = $oRest.AddHeader("Content-Encoding","gzip")

; Indicate the Content-Type of our upload.  (This is optional)
$bSuccess = $oRest.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)
$bSuccess = $oRest.AddHeader("Expect","100-continue")

; Upload the file to Amazon S3.
Local $sResponseBodyStr = $oRest.FullRequestString("PUT","/hamlet_play.xml",$sFileContents)
