Deleting Objects

Deleting a Single Object

You can call ObsClient->deleteObject to delete a single object. Sample 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',
      'signature' => 'obs'
] );

$resp = $obsClient->deleteObject ( [
       'Bucket' => 'bucketname',
       'Key' => 'objectname'
] );
printf("RequestId:%s\n", $resp['RequestId']);

Batch Deleting Objects

You can call ObsClient->deleteObjects to delete objects in a batch.

A maximum of 1000 objects can be deleted each time. Two response modes are supported: verbose (detailed) and quiet (brief).

• In verbose mode (default mode), the returned response includes the deletion result of each requested object.
• In quiet mode, the returned response includes only results of objects failed to be deleted.

Sample code:

// 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',
      'signature' => 'obs'
] );

$resp = $obsClient->deleteObjects ( [ 
              'Bucket' => 'bucketname',
              // Set the response mode to verbose.
              'Quiet' => false,
              'Objects' => [ 
                           [ 
                                         'Key' => 'objectname1',
                                         'VersionId' => null 
                           ],
                           [ 
                                         'Key' => 'objectname2',
                                         'VersionId' => null 
                           ] 
              ] 
] );
printf ( "RequestId:%s\n", $resp ['RequestId'] );
// Obtain the successfully deleted objects.
printf ( "Deleteds:\n" );
foreach ( $resp ['Deleteds'] as $index => $deleted ) {
       printf ( "Deleteds[%d]", $index + 1 );
       printf ( "Key:%s\n", $deleted ['Key'] );
       printf ( "VersionId:%s\n", $deleted ['VersionId'] );
       printf ( "DeleteMarker:%s\n", $deleted ['DeleteMarker'] );
       printf ( "DeleteMarkerVersionId:%s\n", $deleted ['DeleteMarkerVersionId'] );
}
// Obtain the objects failed to be deleted.
printf ( "Errors:\n" );
foreach ( $resp ['Errors'] as $index => $error ) {
       printf ( "Errors[%d]", $index + 1 );
       printf ( "Key:%s\n", $error ['Key'] );
       printf ( "VersionId:%s\n", $$error ['VersionId'] );
       printf ( "Code:%s\n", $error ['Code'] );
       printf ( "Message:%s\n", $error ['Message'] );
}

Use the Quiet parameter to specify the response mode and the Objects parameter to specify the to-be-deleted objects.
