Identifying Whether a Bucket Exists

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->headBucket to identify whether a bucket exists.

This example checks whether bucket bucketname exists.

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 {
     // Check whether a bucket exists.
     $resp = $obsClient->headBucket([
        'Bucket' => 'bucketname'
     ]);
     printf("RequestId:%s\n", $resp['RequestId']);
} catch (ObsException $e) {
      // If the operation fails, obtain the exception details.
      printf("headBucketFailed: Status:%d, Code:%s, Message:%s\n",
         $e->getStatusCode(), $e->getExceptionCode(), $e->getExceptionMessage());
} finally {
      // Close ObsClient to release resources.
      $obsClient->close();
}

If an exception is thrown and the returned HTTP status code is 404, the bucket does not exist.
