Object Storage Service:Manage object ACLs (PHP SDK V2)

1. Set the ACL of an object

<?php

require_once __DIR__ . '/../vendor/autoload.php';

use AlibabaCloud\Oss\V2 as Oss;

$optsdesc = [
    "region" => ['help' => 'The region in which the bucket is located.', 'required' => True],
    "endpoint" => ['help' => 'The domain names that other services can use to access OSS.', 'required' => False],
    "bucket" => ['help' => 'The name of the bucket', 'required' => True],
    "key" => ['help' => 'The name of the object', 'required' => True],
];

// Create an array of long options, such as --region:, for getopt to parse.
$longopts = array_map(function ($key) {
    return "$key:";
}, array_keys($optsdesc));

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

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

// Extract the parameter values.
$region = $options["region"];
$bucket = $options["bucket"];
$key = $options["key"];

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

// Load the default configurations and set the credential provider and region.
$cfg = Oss\Config::loadDefault();
$cfg->setCredentialsProvider($credentialsProvider);
$cfg->setRegion($region);

// If an endpoint is specified, set the custom endpoint.
if (isset($options["endpoint"])) {
    $cfg->setEndpoint($options["endpoint"]);
}

// Initialize the OSS client.
$client = new Oss\Client($cfg);

// Create a PutObjectAclRequest object, and set the bucket name, object key, and ACL type.
$request = new Oss\Models\PutObjectAclRequest($bucket, $key, Oss\Models\ObjectACLType::PUBLIC_READ);

// Send the request to set the ACL of the object to public-read.
$result = $client->putObjectAcl($request);

// Print the status code and request ID in the response.
printf(
    'status code:' . $result->statusCode . PHP_EOL .
    'request id:' . $result->requestId
);

2. Query the ACL of an object

<?php

// Import the autoloader file to load dependency libraries.
require_once __DIR__ . '/../vendor/autoload.php';

use AlibabaCloud\Oss\V2 as Oss;

// Define the descriptions for command line parameters.
$optsdesc = [
    "region" => ['help' => 'The region in which the bucket is located', 'required' => True], // The region is a required parameter. It specifies the region where the bucket is located.
    "endpoint" => ['help' => 'The domain names that other services can use to access OSS', 'required' => False], // The endpoint is an optional parameter. It specifies the domain name that other services can use to access OSS.
    "bucket" => ['help' => 'The name of the bucket', 'required' => True], // The bucket name is a required parameter.
    "key" => ['help' => 'The name of the object', 'required' => True], // The object name is a required parameter.
];

// Generate a list of long options to parse command line arguments.
$longopts = \array_map(function ($key) {
    return "$key:"; // Add a colon (:) after each parameter to indicate that a value is required.
}, array_keys($optsdesc));

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

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

// Obtain the values of the command line parameters.
$region = $options["region"]; // The region where the bucket is located.
$bucket = $options["bucket"]; // The name of the bucket.
$key = $options["key"]; // The name of the object.

// Load credentials, including the AccessKey ID and AccessKey secret, from environment variables.
$credentialsProvider = new Oss\Credentials\EnvironmentVariableCredentialsProvider();

// Use the default configurations of the SDK.
$cfg = Oss\Config::loadDefault();

// Set the credential provider.
$cfg->setCredentialsProvider($credentialsProvider);

// Set the region.
$cfg->setRegion($region);

// If an endpoint is provided, set the endpoint.
if (isset($options["endpoint"])) {
    $cfg->setEndpoint($options["endpoint"]);
}

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

// Create a request object to query the ACL of the object.
$request = new Oss\Models\GetObjectAclRequest(bucket: $bucket, key: $key);

// Call the getObjectAcl method to query the ACL of the object.
$result = $client->getObjectAcl($request);

// Print the result.
printf(
    'status code:' . $result->statusCode . PHP_EOL . // The HTTP response status code.
    'request id:' . $result->requestId . PHP_EOL . // The unique ID of the request.
    'acl:' . $result->accessControlList->grant // The ACL of the object.
);
