; 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 Azure Storage Blob Service
Local $bTls = True
Local $iPort = 443
Local $bAutoReconnect = True
; In this example, the storage account name is "chilkat".
Local $bSuccess = $oRest.Connect("chilkat.blob.core.windows.net",$iPort,$bTls,$bAutoReconnect)
If ($bSuccess <> True) Then
    ConsoleWrite($oRest.LastErrorText & @CRLF)
    Exit
EndIf

; Provide Azure Cloud credentials for the REST call.
$oAzAuth = ObjCreate("Chilkat.AuthAzureStorage")
$oAzAuth.AccessKey = "AZURE_ACCESS_KEY"
; The account name used here should match the 1st part of the domain passed in the call to Connect (above).
$oAzAuth.Account = "chilkat"
$oAzAuth.Scheme = "SharedKey"
$oAzAuth.Service = "Blob"
; This causes the "x-ms-version: 2021-08-06" header to be automatically added.
$oAzAuth.XMsVersion = "2021-08-06"
$bSuccess = $oRest.SetAuthAzureStorage($oAzAuth)

; Note: The application does not need to explicitly set the following
; headers: Content-Length, x-ms-date, Authorization.  These headers
; are automatically set by Chilkat.

; Add the x-ms-range header.
; See x-ms-range Header Format
; The file we're downloading contains "Hello World!", so we'll download just the "World!" part..
$oRest.AddHeader("x-ms-range","bytes=6-")

; The Azure blob container is "test", the file is "helloWorld.txt"
$oSb = ObjCreate("Chilkat.StringBuilder")
$bSuccess = $oRest.FullRequestNoBodySb("GET","/test/helloWorld.txt",$oSb)
If ($bSuccess = False) Then
    ; Examine the request/response to see what happened.
    ConsoleWrite("response status code = " & $oRest.ResponseStatusCode & @CRLF)
    ConsoleWrite("response status text = " & $oRest.ResponseStatusText & @CRLF)
