Obtaining Object Properties

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->getObjectMetadata to obtain properties of an object, including the length, MIME type, customized metadata.

This example obtains the metadata of objectname in bucketname.

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 -> getObjectMetadata([
       'Bucket' => 'bucketname',
       'Key' => 'objectname'
]);

printf("RequestId:%s\n", $resp['RequestId']);
printf("ContentType:%s\n", $resp['ContentType']);
printf("ContentLength:%s\n", $resp['ContentLength']);
printf("Metadata:%s\n", print_r($resp['Metadata'], true));
