Deleting Objects

Deleting a Single Object

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

try {
    $resp = $obsClient->deleteObject([
        'Bucket' => 'bucketname',
        'Key' => 'objectname'
    ]);
    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();
}

Batch Deleting Objects

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

A maximum of 1,000 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:

<?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',
    'signature' => 'obs'
]);

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", $deleted ['DeleteMarkerVersionId']);
}
// Obtain the objects failed to be deleted.
printf( "Errors:\n" );
foreach ($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.
