(AutoIt) Upload using Azure Storage Account Shared Access Signature (SAS) Authorization

Sample code to upload binary bytes to a block blob in Azure Cloud Storage using an Azure Storage Account Shared Access Signature (SAS) Authorization. This creates a block blob, or replaces an existing block blob.

Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that..

Note: This example requires Chilkat v9.5.0.65 or later.

; Note: This example requires Chilkat v9.5.0.65 or greater.

; Azure Blob Service Example: Upload binary bytes to a block blob.
; This uses a Shared Access Signature (SAS) for Authorization.
; This creates a new block blob or replaces an existing one in its entirety.
; See also: https://msdn.microsoft.com/en-us/library/azure/dd179451.aspx

; 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

; The code above this comment could be placed inside a function/subroutine within the application
; because the connection does not need to be made for every request.  Once the connection is made
; the app may send many requests..
; ----------------------------------------------------------------------------------------------

; 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.

; Let's load a previously computed Azure Storage Account SAS token and use it.
; See How to Create an Azure Storage Account Shared Access Signature
$oSbToken = ObjCreate("Chilkat.StringBuilder")
$bSuccess = $oSbToken.LoadFile("qa_data/tokens/azureStorageAccountSas.txt","utf-8")
If ($bSuccess <> True) Then
    ConsoleWrite("Failed to load SAS token." & @CRLF)
    Exit
EndIf

; Add the Shared Access Signature query params for authorization.
$oRest.AddQueryParams($oSbToken.GetAsString())

; IMPORTANT: Make sure to set the x-ms-blob-type header:
$bSuccess = $oRest.AddHeader("x-ms-blob-type","BlockBlob")

; IMPORTANT: Make sure to add the x-ms-date header.
; When the header name is "x-ms-date", Chilkat will recognize the keyword "NOW" 
; and will substitute the current system date/time formatted as required by Microsoft.
$bSuccess = $oRest.AddHeader("x-ms-date","NOW")

; For this example, we'll just load a JPG file into memory..
$oBinData = ObjCreate("Chilkat.BinData")
$bSuccess = $oBinData.LoadFile("qa_data/jpg/starfish.jpg")
If ($bSuccess <> True) Then
    ConsoleWrite("Failed to load JPG file." & @CRLF)
    Exit
EndIf

; Note: The maximum size of a block blob created by uploading in a single step is 64MB.  
; For larger files, the upload must be broken up into blocks.  There is another Chilkat example for that..
$oSbResponse = ObjCreate("Chilkat.StringBuilder")

If ($bSuccess <> True) Then

; When successful, the Azure Storage service will respond with a 201 response status code,
; with no response body.
If ($oRest.ResponseStatusCode <> 201) Then
    ; Examine the request/response to see what happened.
