Setting Lifecycle Rules

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.

You can call ObsClient->setBucketLifecycle to set lifecycle rules for a bucket.

Setting an Object Transition Policy

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'

] );

$resp = $obsClient->setBucketLifecycle ( [ 
       'Bucket' => 'bucketname',
       'Rules' => [ 
                     [ 
                           'ID' => 'rule1',
                           'Prefix' => 'prefix1',
                           'Status' => 'Enabled',
                           // Specify that objects whose names contain the specified prefix will be transitioned to OBS Infrequent Access 30 days after creation.
                           'Transitions' => [ 
                                 [
                                     'StorageClass' => ObsClient::StorageClassWarm,
                                     'Days' => 30
                                 ] 
                           ],
                           // Specify that objects whose names contain the specified prefix will be transitioned to OBS Archive after being noncurrent for 30 days.
                           'NoncurrentVersionTransitions' => [ 
                                 [
                                     'StorageClass' => ObsClient::StorageClassCold,
                                     'NoncurrentDays' => 30
                                 ]                                        
                           ] 
                     ],
                     [ 
                           'ID' => 'rule2',
                           'Prefix' => 'prefix2',
                           'Status' => 'Enabled',
                           // Specify the date when objects whose names contain the specified prefix will be transitioned to OBS Infrequent Access.
                           'Transitions' => [ 
                                    [
                                        'StorageClass' => ObsClient::StorageClassWarm,
                                        'Date' => '2018-12-31T00:00:00Z'
                                    ]                                       
                           ] 
                     ] 
       ] 
] );
printf ( "RequestId:%s\n", $resp ['RequestId'] );

Setting an Object Expiration Time

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',
] );

$resp = $obsClient->setBucketLifecycle ( [ 
       'Bucket' => 'bucketname',
       'Rules' => [ 
                     [ 
                           'ID' => 'rule1',
                           'Prefix' => 'prefix1',
                           'Status' => 'Enabled',
                           // Specify that objects whose names contain the prefix will expire after being created for 60 days.
                           'Expiration' => [ 
                                         'Days' => 60
                           ],
                           // Specify that objects whose names contain the prefix will expire after becoming noncurrent versions for 60 days.
                           'NoncurrentVersionExpiration' => [ 
                                         'NoncurrentDays' => 60 
                           ] 
                     ],
                     [ 
                           'ID' => 'rule2',
                           'Prefix' => 'prefix2',
                           'Status' => 'Enabled',
                           // Specify a date when the objects whose name contain the prefix will expire. The value must conform to the ISO8601 standards and must be at 00:00 (UTC time).
                           'Expiration' => [ 
                                         'Date' => '2018-12-31T00:00:00Z' 
                           ] 
                     ] 
       ] 
] );
printf ( "RequestId:%s\n", $resp ['RequestId'] );

Use the Rules parameter to specify the lifecycle rules for a bucket.
