Azure Storage: Upload Contents of String Variable to Block Blob

See more Azure Cloud Storage Examples

Sample code to upload the contents of a string variable 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..

PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

# Azure Blob Service Example: Upload the contents of a string variable 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.

$rest = New-Object Chilkat.Rest

# Connect to the Azure Storage Blob Service
$bTls = $true
$port = 443
$bAutoReconnect = $true
# In this example, the storage account name is "chilkat".
$success = $rest.Connect("chilkat.blob.core.windows.net",$port,$bTls,$bAutoReconnect)
if ($success -ne $true) {
    $($rest.LastErrorText)
    exit
}

# Provide Azure Cloud credentials for the REST call.
$azAuth = New-Object 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")

# After uploading, the block blob named helloWorld.txt (in the container named "mycontainer")
# will contain the following string:
$blobContents = "Hello World!"

# 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..
$responseStr = $rest.FullRequestString("PUT","/mycontainer/helloWorld.txt",$blobContents)
if ($rest.LastMethodSuccess -ne $true) {
    $($rest.LastErrorText)
    exit
}

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

if ($rest.ResponseStatusCode -ne 201) {
    # Examine the request/response to see what happened.
    $("response status code = " + $rest.ResponseStatusCode)
    $("response status text = " + $rest.ResponseStatusText)
    $("response header: " + $rest.ResponseHeader)
    $("response body (if any): " + $responseStr)
    $("---")
    $("LastRequestStartLine: " + $rest.LastRequestStartLine)
    $("LastRequestHeader: " + $rest.LastRequestHeader)
    exit
}

$("Success.")
