(AutoIt) Upload In-Memory Binary Data to Google Cloud Storage

Demonstrates how to upload in-memory binary data to Google Cloud Storage.

Note: This example requires Chilkat v9.5.0.69 or later because it uses the http.PBinaryBd method.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

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

; This example uses a previously obtained access token having permission for the 
; scope "https://www.googleapis.com/auth/cloud-platform"

; In this example, Get Google Cloud Storage OAuth2 Access Token, 
; the service account access token was saved to a text file.  This example fetches the access token from the file..
$oSbToken = ObjCreate("Chilkat.StringBuilder")
$oSbToken.LoadFile("qa_data/tokens/googleCloudStorageAccessToken.txt","utf-8")

; Send a POST equivalent to this curl command.
; The content of the file is contained in the request body.

; curl -X POST --data-binary @[OBJECT] \
;     -H "Authorization: Bearer [OAUTH2_TOKEN]" \
;     -H "Content-Type: [OBJECT_CONTENT_TYPE]" \
;     "https://www.googleapis.com/upload/storage/v1/b/[BUCKET_NAME]/o?uploadType=media&name=[OBJECT_NAME]"

; Download a JPG image from the Internet, and then upload this JPG to
; a Google Storage bucket.

$oJpgData = ObjCreate("Chilkat.BinData")
Local $bSuccess = $oHttp.DownloadBd($sJpgUrl,$oJpgData)
If ($bSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)

EndIf

; Construct a URL to upload to an object named "starfish.jpg" in the "chilkat-ocean" bucket.

Local $sUrl = "https://www.googleapis.com/upload/storage/v1/b/{$bucket_name}/o?uploadType=media&name={$object_name}"

; Note: The PBinaryBd method first appears in Chilkat v9.5.0.69

EndIf
