Azure Storage: Upload Binary Data to Block Blob

See more Azure Cloud Storage Examples

Sample code to upload binary bytes to a block blob in Azure Cloud Storage. This creates the 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..

;  Azure Blob Service Example: Upload binary bytes to a block blob.
;  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".
$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.

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

;  For this example, we'll just load a JPG file into memory..
Local $oBinaryData
$oFac = ObjCreate("Chilkat.FileAccess")

;  When successful, the Azure Storage service will respond with a 201 response status code,
;  with no response body.

    ;  Examine the request/response to see what happened.
