Creating a Folder

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.

There is no folder concept in OBS. All elements in buckets are objects. To create a folder in OBS is essentially to create an object whose size is 0 and whose name ends with a slash (/). Such objects have no difference from other objects and can be downloaded and deleted, except that they are displayed as folders in OBS Console.

// 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->putObject([
       'Bucket' => 'bucketname',
       'Key' => 'parent_directory/'
]);

printf("RequestId:%s\n",$resp['RequestId']);
// Create an object in the folder.
$resp = $obsClient->putObject([
       'Bucket' => 'bucketname',
       'Key' => 'parent_directory/objectname',
       'Body' => 'Hello OBS',
]);

printf("RequestId:%s\n",$resp['RequestId']);

• To create a folder in OBS is to create an object whose size is 0 and whose name ends with a slash (/), in essential.
• To create a multi-level folder, you only need to create the folder with the last level. For example, if you want to create a folder named src1/src2/src3/, create it directly, no matter whether the src1/ and src1/src2/ folders exist.
