How to upload files to Microsoft AZure blobs using SAS token
Purpose: Uploads a file to an Azure Blob Storage container using REST API.


Parameters:
$accountName: The name of the Azure Storage Account.


$containerName: The name of the Blob container within the storage account.


$blobName: The desired name for the blob in the container.


$filePath: The local file path of the file to upload.


$SAS_token: The SAS token copied from AZure portal.



Steps:
Blob URL Construction:


The blob URL is built using the storage account name, container name, and blob name.


Includes a placeholder for the authorization key (SAS_token).


Header Configuration:


A dictionary $headers is set with the "x-ms-blob-type" header set to "BlockBlob", which is the type of blob being uploaded.


File Content Reading:


The content of the file at the given path is read into a byte array using [System.IO.File]::ReadAllBytes($filePath).


Uploading File:


Invoke-RestMethod sends a PUT request to the blob URL with the file content in the body and the appropriate headers.


The content type for the request is set to "application/octet-stream".


Error Handling:


The script is enclosed in a try-catch block to handle potential errors during the upload.


If an error occurs, it logs an error message with the failure details.



Sample Code:-

function Upload_files_to_Azure_blobs
{
param(
blob_accountName,
blob_containerName,
blob_blobName,
blob_filePath,
blob_SAS_Token
)

Write-Host "Uploading $blob_blobName to container $blob_containerName..."
$blobUrl = "https://$blob_accountName.blob.core.windows.net/$blob_containerName/$blob_blobName?blob_$SAS_Token"

$headers = @{
"x-ms-blob-type" = "BlockBlob"
}
try
{
$fileContent = [System.IO.File]::ReadAllBytes($filePath)
Invoke-RestMethod -Uri $blobUrl -Method Put -Headers $headers -Body $fileContent -ContentType "application/octet-stream"
Write-Host "Uploaded $blob_blobName successfully."
}
catch
{
Write-Error "Failed to upload $blob_blobName : $_"
}
}

Note:- Append the "?" to SAS token as shown in $blobUrl
