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

* When usig the REST class to access an S3 bucket that has been created in a particular region,
* there are three important things to remember:
* 
* 1) Connect to the domain that includes the region.  For example, instead of connecting to
*    "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
*    See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
* 
* 2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
* 
* 3) Include the region in request's Host header.
* 

* This example will upload to a bucket in the eu-central-1 region.
* 
loRest = CreateObject('Chilkat_9_5_0.Rest')

* Connect to the Amazon AWS REST server.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("s3.eu-central-1.amazonaws.com",lnPort,lnBTls,lnBAutoReconnect)

* Provide AWS credentials for the REST call.
loAuthAws = CreateObject('Chilkat_9_5_0.AuthAws')
loAuthAws.AccessKey = "AWS_ACCESS_KEY"
loAuthAws.SecretKey = "AWS_SECRET_KEY"
loAuthAws.ServiceName = "s3"
loAuthAws.Region = "eu-central-1"
lnSuccess = loRest.SetAuthAws(loAuthAws)

* Set the bucket name via the HOST header.
* In this case, the bucket name is "chilkateufrankfurt" (which was created in the eu-central-1 region)
loRest.Host = "chilkateufrankfurt.s3.eu-central-1.amazonaws.com"

loFileData = CreateObject('Chilkat_9_5_0.BinData')
lnSuccess = loFileData.LoadFile("qa_data/jpg/penguins.jpg")

* Upload the file to Amazon S3.
loResponseBody = CreateObject('Chilkat_9_5_0.StringBuilder')
lnSuccess = loRest.FullRequestBd("PUT","/penguins.jpg",loFileData,loResponseBody)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAuthAws
    RELEASE loFileData
    RELEASE loResponseBody
    CANCEL
ENDIF

* Did we get a 200 response indicating success?
lnStatusCode = loRest.ResponseStatusCode
IF (lnStatusCode <> 200) THEN
    ? "Error response: " + loResponseBody.GetAsString()
    ? "Status code: " + STR(lnStatusCode) + ", Status text: " + loRest.ResponseStatusText
    RELEASE loRest
    RELEASE loAuthAws
    RELEASE loFileData
    RELEASE loResponseBody
    CANCEL
ENDIF

? "File successfully uploaded."

RELEASE loRest
RELEASE loAuthAws
RELEASE loFileData
RELEASE loResponseBody
