DTF DBS API Client

Requirements

• PHP 7.4 or 8.x
• HTTP client(this readme describes Guzzle example, but you can use any other PSR18 complaint package). Check these packages https://packagist.org/providers/psr/http-client-implementation if you need Guzzle alternative.

Installation via Composer

Run in command line:

composer require ybelenko/dtf-dbs-client

Setup

Via PHP-DI container

API services

File List Service

// $client initialization omitted

    }
} catch (\Throwable $e) {
    // echo or log exception for following investigation
}

File Upload Service

// $client initialization omitted
try {
    $factory = new \GuzzleHttp\Psr7\HttpFactory();
    $testFile = $factory->createStreamFromFile(__DIR__ . '/tests/samplecommonfile.txt', 'r');
    /** @var bool */
