Obtaining Customized Metadata

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.

After an object is successfully downloaded, its customized data is returned.

This example downloads object objectname from bucketname and returns the custom metadata of the object.

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

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

• If Metadata is left blank, the object has no custom metadata configured.
• For details about the meanings, causes, and handling methods of error codes that may be returned during the operation, see SDK Error Codes.
