README

A Laravel package that provides Azure Blob Storage URL generation with SAS (Shared Access Signature) tokens for Spatie Laravel Media Library.

This package extends Spatie's default URL generator to produce Azure Blob Storage URLs with SAS token authentication, enabling secure access to media files stored in Azure Blob Storage.

Requirements

• PHP 8.2 or higher
• Laravel (with Illuminate Support)
• spatie/laravel-medialibrary ^11.17
• azure-oss/storage-blob-laravel ^1.4

Installation

Install the package via Composer:

composer require bornmt/azure-blob-url-generator

Register the Service Provider

If you're using Laravel 11+, the service provider may be auto-discovered. Otherwise, add it to the providers array in config/app.php:

'providers' => [
    // ...
    BornMT\AzureBlobUrlGenerator\UrlGeneratorServiceProvider::class,
],

Configuration

1. Environment Variables

Add the following variables to your .env file:

AZURE_STORAGE_ENDPOINT=https://yourstorageaccount.blob.core.windows.net
AZURE_STORAGE_CONTAINER=your-container-name
AZURE_STORAGE_SAS_TOKEN=sv=2021-06-08&ss=b&srt=sco&sp=rl&se=...

Note: Ensure your SAS token has appropriate permissions (e.g., r for read access) and is configured with a suitable expiration for your use case.

2. Configure Spatie Media Library

Update your Spatie Media Library configuration to use this package's URL generator. Publish the media library config if you haven't already:

php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="medialibrary-config"

Then, in config/media-library.php, set the custom URL generator:

'url_generator' => \BornMT\AzureBlobUrlGenerator\Services\UrlGeneratorService::class,

3. Configure Your Filesystem

Add the Azure disk to config/filesystems.php:

'disks' => [
    'azure' => [
        'driver' => 'azure-storage-blob',
        'sasToken' => env('AZURE_STORAGE_SAS_TOKEN'),
        'container' => env('AZURE_STORAGE_CONTAINER'),
        'endpoint' => env('AZURE_STORAGE_ENDPOINT'),
        'connection_string' => sprintf(
            'BlobEndpoint=%s;SharedAccessSignature=%s',
            env('AZURE_STORAGE_ENDPOINT'),
            env('AZURE_STORAGE_SAS_TOKEN')
        ),
    ],
],

Set your default media disk in config/media-library.php or via the MEDIA_DISK environment variable:

MEDIA_DISK=azure

Usage

Once configured, media URLs are generated automatically when you call getUrl() or getTemporaryUrl() on your media items.

Basic Usage with Spatie Media Library

// Add media to a model
$yourModel->addMedia($pathToFile)
    ->toMediaCollection('documents', 'azure');

// Get the Azure Blob SAS URL
$media = $yourModel->getFirstMedia('documents');
$url = $media->getUrl();  // Returns full URL with SAS token

// Get a temporary URL (uses same SAS token - ensure your SAS has appropriate expiration)
$temporaryUrl = $media->getTemporaryUrl(now()->addHours(1));

Generated URL Format

URLs are generated in the following format:

{endpoint}/{container}/{path-to-file}?{sas_token}

Example:

https://mystorageaccount.blob.core.windows.net/my-container/media/1/image.jpg?sv=2021-06-08&ss=b&srt=sco&sp=rl&se=...
