README

This PHP package provides functionality to interact with Azure Blob Storage using SAS tokens. It includes authentication, listing files in a folder, and retrieving a file from storage.

📦 Installation

To install this package, run:

composer require acseo/cegid-rfe-connect

This will install all required dependencies, including:

• symfony/http-client
• symfony/cache
• symfony/dotenv (for testing)
• phpunit/phpunit (for testing)

🚀 Usage

Authentication

The Auth\Token class handles authentication and retrieves an access token from the API.

$httpClient = HttpClient::create();
$cache = new FilesystemAdapter();

$tokenService = new Auth\Token($httpClient, $cache, $clientId, $username, $password, $tokenUrl, $cacheDuration);
$token = $auth->getToken();

Fetching a SAS Token

The Auth\SasToken class retrieves a SAS token to access Azure Blob Storage.

$sasTokenService = new Auth\SasToken($httpClient, $cache, $tokenService, $sasTokenUrl, $cacheDuration);
$sasToken = $sasTokenService->getSasToken($tenantId, $storagePath);

Listing Files in a Folder

The RFE\Folder\ListFiles class lists files within a given folder in the blob storage.

$listFiles = new RFE\Folder\ListFiles($httpClient, $sasToken);
$files = $listFiles->listFiles($'some-folder/');

Retrieving a File

The RFE\File\GetFile class fetches the contents of a file stored in Azure Blob Storage.

$getFile = new RFE\File\GetFile($httpClient, $sasToken);
$fileContent = $getFile->getFile('some-folder/myfile.txt');

🧪 Running Tests

Create a .env.test file by copying the .env.test.dist template:

cp .env.test.dist .env.test

Then, update .env.test with the required values:

CLIENT_ID=your_client_id
CLIENT_SECRET=your_client_secret
USERNAME=your_username
PASSWORD=your_password
TOKEN_URL=your_token_url
CACHE_DURATION=3600
SAS_TOKEN_URL=your_sas_token_url
TENANT_ID=your_tenant_id
STORAGE_PATH=your_storage_path
FILE_PATH=your_file_path
FOLDER_PATH=your_folder_path

To execute the PHPUnit test suite, run:

composer test

This will run unit tests for authentication, SAS token retrieval, file listing, and file fetching.

📌 Notes

• Ensure your .env.test file contains valid credentials before running tests.
• Check the Azure Blob Storage permissions when using SAS tokens.
