Deleting Object Versions

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.

Deleting a Single Object Version

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

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

The sample code is as follows:

<?php

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

try {
    $resp = $obsClient->deleteObject([
        'Bucket' => 'bucketname',
        'Key' => 'objectname',
        'VersionId' => 'versionid'
    ]);
    printf( "RequestId:%s\n", $resp['RequestId']);
} catch (ObsException $e) {
    // If the operation fails, obtain the exception details.
    printf("DeleteObjectFailed: Status:%d, Code:%s, Message:%s\n", $e->getStatusCode(), $e->getExceptionCode(), $e->getExceptionMessage());
} finally {
    $obsClient->close();
}

Deleting Object Versions in a Batch

You can call ObsClient->deleteObjects to batch delete specific versions of an object by passing the VersionId value of each version to delete.

This example deletes objects objectname1 and objectname2 from bucket bucketname in a batch by specifying their version IDs.

The sample code is as follows:

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

try {
    $resp = $obsClient->deleteObjects([
        'Bucket' => 'bucketname',
        // Set the response mode to verbose.
        'Quiet' => false, // false: Detailed mode. Both success and failure results are returned. true: Simple mode. Only failure results are returned.
        'Objects' => [
            [
                'Key' => 'objectname1',
                'VersionId' => null
            ],
            [
                'Key' => 'objectname2',
                'VersionId' => null
            ]
        ]
    ]);
    printf( "RequestId:%s\n", $resp['RequestId']);
    // Obtain the successfully deleted objects.
    printf( "Deleteds:\n" );
} catch (ObsException $e) {
    // If the operation fails, obtain the exception details.
    printf("DeleteObjectsFailed: Status:%d, Code:%s, Message:%s\n", $e->getStatusCode(), $e->getExceptionCode(), $e->getExceptionMessage());
} finally {
    $obsClient->close();
}
foreach ($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", $deleted ['DeleteMarkerVersionId']);
}
// Obtain the objects that failed to be deleted.
printf( "Errors:\n" );
foreach ($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']);
}
