Object Storage Service:Convert the storage class of an object (PHP SDK V2)

You can use the CopyObject method to convert the storage class of an object from Standard to Archive.

<?php

// Introduce autoload files to load dependency libraries.
require_once __DIR__ . '/../vendor/autoload.php';

use AlibabaCloud\Oss\V2 as Oss;

// Define and describe command-line parameters.
$optsdesc = [
    "region" => ['help' => 'The region in which the bucket is located.', 'required' => True], // (Required) Specify the region in which the bucket is located.
    "endpoint" => ['help' => 'The domain names that other services can use to access OSS.', 'required' => False], // (Optional) Specify the endpoint for accessing OSS.
    "bucket" => ['help' => 'The name of the bucket', 'required' => True], // (Required) Specify the name of the destination bucket.
    "key" => ['help' => 'The name of the object', 'required' => True], // (Required) Specify the name of the destination object.
    "src-bucket" => ['help' => 'The name of the source bucket', 'required' => False], // (Optional) Specify the name of the source bucket.
    "src-key" => ['help' => 'The name of the source object', 'required' => True], // (Required) Specify the name of the source object.
];

// Convert the descriptions to a list of long options required by getopt.
// Add a colon (:) to the end of each parameter to indicate that a value is required.
$longopts = \array_map(function ($key) {
    return "$key:";
}, array_keys($optsdesc));

// Parse the command-line parameters.
$options = getopt("", $longopts);

// Check whether the required parameters are configured.
foreach ($optsdesc as $key => $value) {
    if ($value['required'] === True && empty($options[$key])) {
        $help = $value['help']; // Obtain help information for the parameters.
        echo "Error: the following arguments are required: --$key, $help" . PHP_EOL;
        exit(1); // Exit the program if the required parameters are not configured.
    }
}

// Assign the values parsed from the command-line parameters to the corresponding variables.
$region = $options["region"]; // The region in which the bucket is located.
$bucket = $options["bucket"]; // The name of the destination bucket.
$key = $options["key"]; // The name of destination object.
$srcKey = $options["src-key"]; // The name of the source object.

// Load access credentials from environment variables.
// Use EnvironmentVariableCredentialsProvider to retrieve the AccessKey ID and AccessKey secret from environment variables.    
$credentialsProvider = new Oss\Credentials\EnvironmentVariableCredentialsProvider();

// Use the default configuration of the SDK.
$cfg = Oss\Config::loadDefault();
$cfg->setCredentialsProvider($credentialsProvider); // Specify the credential provider.
$cfg->setRegion($region); // Specify the region in which the bucket is located.
if (isset($options["endpoint"])) {
    $cfg->setEndpoint($options["endpoint"]); // Specify the endpoint if one is provided.
}

// Create an OSS client instance.
$client = new Oss\Client($cfg);

// Create a CopyObjectRequest object to copy the source object.
$request = new Oss\Models\CopyObjectRequest(
            bucket: $bucket,
            key: $key,
            sourceKey: $srcKey,
            sourceBucket: $bucket,
            storageClass: 'Archive' // Set the storage class to Archive.

if (!empty($options["src-bucket"])) {
    $request->sourceBucket = $options["src-bucket"]; // If the source bucket name is provided, specify the sourceBucket parameter.
}
$request->sourceKey = $srcKey; // Specify the name of the source object.

// Perform the object copy operation.
$result = $client->copyObject($request);

// Display the object copy result.
printf(
    'status code:' . $result->statusCode . PHP_EOL . // The HTTP status code. For example, HTTP status code 200 indicates that the request succeeded.
    'request id:' . $result->requestId . PHP_EOL     // The request ID, which can be used to debug or trace the request.
);

We recommend you use the Copier.Copy method in OSS SDK for PHP 2.0 to convert the storage class. This method combines the simple copy and multipart copy operations and intelligently selects the most suitable one according to the provided request parameters.

Below is the sample code for using the Copier.Copy method to convert the storage class of an object from Standard to Archive.

<?php

// Introduce autoload files to load dependency libraries.
require_once __DIR__ . '/../vendor/autoload.php';

use AlibabaCloud\Oss\V2 as Oss;

// Define and describe command-line parameters.
$optsdesc = [
    "region" => ['help' => 'The region in which the bucket is located.', 'required' => True], // (Required) Specify the region in which the bucket is located.
    "endpoint" => ['help' => 'The domain names that other services can use to access OSS.', 'required' => False], // (Optional) Specify the endpoint.
    "bucket" => ['help' => 'The name of the bucket', 'required' => True], // (Required) Specify the name of the bucket.
    "key" => ['help' => 'The name of the object', 'required' => True], // (Required) Specify the name of the destination object.
    "src-key" => ['help' => 'The name of the source object', 'required' => True], // (Required) Specify the name of the source object.
];

// Convert the descriptions to a list of long options required by getopt.
// Add a colon (:) to the end of each parameter to indicate that a value is required.
$longopts = \array_map(function ($key) {
    return "$key:";
}, array_keys($optsdesc));

// Parse the command-line parameters.
$options = getopt("", $longopts);

// Check whether the required parameters are configured.
foreach ($optsdesc as $key => $value) {
    if ($value['required'] === True && empty($options[$key])) {
        $help = $value['help']; // Obtain help information for the parameters.
        echo "Error: the following arguments are required: --$key, $help" . PHP_EOL;
        exit(1); // Exit the program if a required parameter is missing.
    }
}

// Obtain values from the parsed parameters.
$region = $options["region"]; // The region in which the bucket is located.
$bucket = $options["bucket"]; // The name of the bucket.
$key = $options["key"];       // The name of the destination object.
$srcKey = $options["src-key"]; // The name of the source object.

// Load access credentials from environment variables.
// Use EnvironmentVariableCredentialsProvider to retrieve the AccessKey ID and AccessKey secret from environment variables.    
$credentialsProvider = new Oss\Credentials\EnvironmentVariableCredentialsProvider();

// Use the default configuration of the SDK.
$cfg = Oss\Config::loadDefault();
$cfg->setCredentialsProvider($credentialsProvider); // Specify the credential provider.
$cfg->setRegion($region); // Specify the region in which the bucket is located.
if (isset($options["endpoint"])) {
    $cfg->setEndpoint($options["endpoint"]); // Specify the endpoint if one is provided.
}

// Create an OSSClient instance.
$client = new Oss\Client($cfg);

// Create a Copier instance.
$copier = $client->newCopier();

$dstKey = $key; // The name of the destination object.
$copyRequest = new Oss\Models\CopyObjectRequest(
    bucket: $bucket,
    key: $dstKey,
    sourceBucket: $bucket,
    sourceKey: $srcKey,
    storageClass: "Archive");

$result = $copier->copy(
    request: $copyRequest,
);

printf(
    'status code:' . $result->statusCode . PHP_EOL . // The HTTP status code. For example, HTTP status code 200 indicates that the request succeeded.
    'request id:' . $result->requestId . PHP_EOL     // The request ID, which can be used to debug or trace the request.
);
