Object Storage Service:Hotlink protection using OSS SDK for PHP 2.0

This code shows how to configure hotlink protection:

<?php

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

use AlibabaCloud\Oss\V2 as Oss;

// Define the command-line argument descriptions.
$optsdesc = [
    "region" => ['help' => 'The region in which the bucket is located', 'required' => True], // The region is required. This is 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 optional. This is the domain name that other services can use to access OSS.
    "bucket" => ['help' => 'The name of the bucket', 'required' => True], // The bucket name is required.
];

// 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 for missing required parameters.
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 argument values.
$region = $options["region"]; // The region where the bucket is located.
$bucket = $options["bucket"]; // The bucket name.

// Use environment variables to load credential information, including AccessKeyId and AccessKeySecret.
$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 set the hotlink protection configuration for the bucket. Configure allowEmptyReferer to false and set the Referer list.
$request = new Oss\Models\PutBucketRefererRequest(bucket: $bucket,
    refererConfiguration: new Oss\Models\RefererConfiguration(
        allowEmptyReferer: false,
        refererList: new Oss\Models\RefererList([""]),
    )
);

// Call the putBucketReferer method to set the hotlink protection configuration for the bucket.
$result = $client->putBucketReferer($request);

// Print the result.
printf(
    'status code:' . $result->statusCode . PHP_EOL . // The HTTP response status code.
    'request id:' . $result->requestId // The unique identifier of the request.
);

This code shows how to retrieve the hotlink protection configuration:
