Initializing an Instance of ObsClient

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

Each time you want to send an HTTP/HTTPS request to OBS, you must create an instance of ObsClient. Sample code is as follows:

<?php

// Before initializing an instance of ObsClient, you must import dependencies.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with the source code.
// require 'obs-autoloader.php';

// Declare the namespace.
use Obs\ObsClient;

// Create an ObsClient instance.
$obsClient = new ObsClient([
    // Obtain an AK/SK pair using environment variables (recommended) or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
    'key' => getenv('ACCESS_KEY_ID'),
    'secret' => getenv('SECRET_ACCESS_KEY'),
    'endpoint' => 'https://your-endpoint',
]);

// Use ObsClient to access OBS.

// Close ObsClient.
$obsClient->close();
