Object Storage Service:Manage object ACLs using OSS SDK for PHP 2.0

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 required by getopt. Example: --region:.
$longopts = array_map(function ($key) {
    return "$key:";
}, array_keys($optsdesc));

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

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

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

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

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

// If the endpoint parameter is specified, it will be configured as the custom access URL.
if (isset($options["endpoint"])) {
    $cfg->setEndpoint($options["endpoint"]);
}

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

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

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

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

2. Query the ACL of a bucket.

<?php

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

use AlibabaCloud\Oss\V2 as Oss;

// Specify descriptions for 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 OSS 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 object.
];

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

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

// Check whether the 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"; // Display the required but missing parameters.
        exit(1); 
    }
}

// Obtain the values of the command line 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 object.

// Load 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();

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

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

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

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

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

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

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