Obtaining a Versioning Object

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.

You can call ObsClient->getObject to obtain an object version by specifying the version ID (VersionId).

This example downloads object objectname from bucket bucketname by specifying VersionId.

The example code is as follows:

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during source code installation.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an instance of ObsClient.
$obsClient = new ObsClient ( [ 
      //Obtain an AK/SK pair using environment variables or import the 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'
] );

$resp = $obsClient->getObject([
       'Bucket' => 'bucketname',
       'Key' => 'objectname',
       'VersionId' => 'versionid'
]);

printf ("RequestId:%s\n", $resp ['RequestId']);
printf("Object Content:\n");
// Obtain the object content.
echo $resp ['Body'];

• If VersionId is not specified, the object of the latest version will be downloaded.
