(Classic ASP) Azure Storage: Upload Binary Data to Block Blob using BinData

Sample code to upload binary bytes (contained in a Chilkat BinData object) 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.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Rest")
set rest = Server.CreateObject("Chilkat.Rest")

' Connect to the Azure Storage Blob Service
bTls = 1
port = 443
bAutoReconnect = 1
' In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( rest.LastErrorText) & "</pre>"
    Response.End
End If

' Provide Azure Cloud credentials for the REST call.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.AuthAzureStorage")
set azAuth = Server.CreateObject("Chilkat.AuthAzureStorage")
azAuth.AccessKey = "AZURE_ACCESS_KEY"
' The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = "chilkat"
azAuth.Scheme = "SharedKey"
azAuth.Service = "Blob"
' This causes the "x-ms-version: 2021-08-06" header to be automatically added.
azAuth.XMsVersion = "2021-08-06"
success = rest.SetAuthAzureStorage(azAuth)

' 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:
success = rest.AddHeader("x-ms-blob-type","BlockBlob")

' For this example, we'll just load a JPG file into memory..
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.BinData")
set bd = Server.CreateObject("Chilkat.BinData")
success = bd.LoadFile("qa_data/jpg/starfish.jpg")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( "Failed to load the file to be uploaded.") & "</pre>"
    Response.End
End If

' 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..
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")

If (success = 0) Then

    Response.End
End If

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