Managing Bucket Policies

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.

Besides bucket ACLs, bucket owners can use bucket policies to centrally control access to buckets and objects in buckets.

For more information, see Bucket Policy.

Setting a Bucket Policy

You can call ObsClient->setBucketPolicy to set a bucket policy. Sample code is as follows:

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an ObsClient instance.
$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'
] );

$bucketName = "bucketname";
$policy = "{\"Statement\":[{\"Principal\":\"*\",\"Effect\":\"Allow\",\"Action\":\"ListBucket\",\"Resource\":\"" .$bucketName. "\"}]}";

$resp = $obsClient->setBucketPolicy([
       'Bucket' => $bucketName,
       'Policy' => $policy
]);

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

For details about the bucket policies in JSON format, see OBS PHP SDK API Reference.

Obtaining a Bucket Policy

You can call ObsClient->getBucketPolicy to obtain a bucket policy. Sample code is as follows:

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an ObsClient instance.
$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->getBucketPolicy([
       'Bucket' => 'bucketname'
]);

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

Deleting a Bucket Policy

You can call ObsClient->deleteBucketPolicy to delete a bucket policy. Sample code is as follows:

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an ObsClient instance.
$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->deleteBucketPolicy([
       'Bucket' => 'bucketname'
]);

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