Selectel Cloud Storage API

Selectel's Cloud Storage API Client.

Install

Via Composer

$ composer require garantpark/selectel

Basic Usage

<?php
use GarantPark\Selectel\Client;
$client = new Client($username, $password);
$client->createContainer('new-container', 'public');

$localPath = realpath('./image.png');
$remotePath = '/images/image.png';
$client->uploadFile('new-container', $localPath, $remotePath);
// File image.png is now available at http://XXX.selcdn.ru/new-container/images/image.png
// XXX in URL is your Storage ID

Available Methods

Storage info

$storageInfo = $client->getStorageInfo();

Containers list

$containers = $client->getContainers();

Create new container

$containerType = 'public'; // or 'private'
$metaData = []; // Any meta data (will be stored as "X-Container-Meta-{KEY}: {Value}" header)
$result = $client->createContainer('container-name', $containerType, $metaData);

Container info

$containerInfo = $client->getContainerInfo('container-name');

If container does not exists, \GarantPark\Selectel\Exceptions\ContainerNotFoundException will be thrown.

Delete container

$client->deleteContainer('container-name');

If container does not exists, \GarantPark\Selectel\Exceptions\ContainerNotFoundException will be thrown.

Also, if container is not empty, \GarantPark\Selectel\Exceptions\ContainerNotEmptyException will be thrown.

Get container files

$params = [
    'path' => '/images/', // get files from /images/ direcory only
];
// More $params values can be found in Selectel's API docs (see link above).
$files = $client->getContainerFiles('container-name', $params);

If container does not exists, \GarantPark\Selectel\Exceptions\ContainerNotFoundException will be thrown.

Upload file

$localFile = realpath('../../images/logo-big.png');
$remotePath = '/images/logos/logo-big.png';
$file = $client->uploadFile('container-name', $localFile, $remotePath);

If local file is not readable, \GarantPark\Selectel\Exceptions\LocalFileNotAvailableException will be thrown.

If upload fails, GarantPark\Selectel\Exceptions\FileUploadFailedException will be thrown.

Archive upload & unpack

Use same method as for file upload but add third argument $params with extract-archive key.

$localFile = realpath('../../backups/database-backup-latest.tar.gz');
$remotePath = '/backups/database/' . date('Y-m-d') . '.tar.gz';
$params = [
    'extract-archive' => 'tar.gz',
];
$archive = $client->uploadFile('container-name', $localFile, $remotePath, $params);
// $archive will contain additional field 'extract.filesCount'.

If upload fails, GarantPark\Selectel\Exceptions\FileUploadFailedException will be thrown.

If archive extraction fails, GarantPark\Selectel\Exceptions\ArchiveExtractFailedException will be thrown.

Supported archive types:

• tar
• tar.gz
• tar.bz2

Add metadata to a file

$remotePath = '/backups/database/' . date('Y-m-d') . 'tar.gz'; // cloud path
$meta = [
    'Created-By' => 'Backup Manager',
];
$client->setFileMetaData('container-name', $remotePath, $meta);

This will result in adding X-Object-Meta-Created-By header to file with value Backup Manager.

If container does not exists, GarantPark\Selectel\Exceptions\ContainerNotFoundException will be thrown.

Copy file

$srcContainer = 'images-old'; // source container name
$srcPath = '/images/logos/logo-big.png'; // source path (in container)
$dstContainer = 'images-new'; // destination container name
$dstPath = '/images/logos/logo-big-copied.png'; // destination path (in container)
// optional metadata
$meta = [
    'Copied-At' => date('Y-m-d H:i:s'), // add "X-Object-Meta-Copied-At: date" header to copied file
];
$client->copyFile($srcContainer, $srcPath, $dstContainer, $dstPath, $meta);

If source or destination path does not exists, GarantPark\Selectel\Exceptions\ObjectNotFoundException will be thrown.

Delete file

$client->deleteFile('container-name', '/path/to/fille.png');

If file does not exists, GarantPark\Selectel\Exceptions\FileNotFoundException will be thrown.

Create symlink to a file or direcory

$linkPath = '/public/images/structure.png'; // link path (where to store link)
$linkSource = '/private-images/structure.png'; // original file
$params = [
    'type' => 'symlink', // link type, see information below, required
    'deleteAt' => time() + (60 * 60), // link will be deleted in one hour, optional
    'password' => sha1('mySecurePassword' . urlencode($linkSource)), // password, optional
];
$client->createSymlink('container-name', $linkPath, $linkSource, $params);

Available symlink types:

• symlink: basic link,
• onetime-symlink: onetime link (will be deleted after first visit),
• symlink+secure: link with password protection
• onetime-symlink+secure: onetime link with password protection

If you're using password protected link, user must use _sslk query param to get access to this file: http://XXXX.selcdn.ru/container-name/public/images/structure.png?sslk=mySecurePassword

Generate link for a private file download

First of all, you need to set up secret key to an account or a container (one time).

$containerName = 'container-name';
// container-specific secret key
$client->setObjectSecretKey($containerName, 'myContainerSecretKey');
// or account-wide secret key
$client->setObjectSecretKey('/', 'myAccountSecretKey');

If container does not exists, GarantPark\Selectel\Exceptions\ObjectNotFoundException will be thrown.

After doing so, you'll be able to generate signed links.

$remotePath = '/container-name/private-files/account.txt';
$expires = time() + (60 * 60); // expires in 1 hour
$secretKey = 'myAccountSecretKey'; // account or container secret key
$signedUrl = $client->generateSignedLink($remotePath, $expires, $secretKey);
