Obtaining Object Properties

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.
      '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));
