Object Storage Service:Block Public Access global com o OSS SDK for PHP 2.0

Última atualização: Jul 03, 2026

Este tópico descreve como ativar o Block Public Access global do OSS, obter e excluir suas informações de configuração com o OSS SDK for PHP 2.0.

Observações de uso

  • O código de exemplo deste tópico usa o ID da região cn-hangzhou, correspondente à região China (Hangzhou). Por padrão, um endpoint público acessa os recursos de um bucket. Para acessar os recursos do bucket a partir de outros serviços da Alibaba Cloud na mesma região, use um endpoint interno. Para mais informações sobre as regiões e endpoints compatíveis com o OSS, consulte Regiões e endpoints.

Código de exemplo

Ative o Block Public Access global do OSS

O código de exemplo a seguir mostra como ativar o Block Public Access global.

<?php

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

use AlibabaCloud\Oss\V2 as Oss;

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

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

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

// Check whether required arguments 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 argument is missing.
        exit(1);
    }
}

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

// 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);

// Build a PutPublicAccessBlock request to set the Block Public Access configuration.
$request = new Oss\Models\PutPublicAccessBlockRequest(
    publicAccessBlockConfiguration: new Oss\Models\PublicAccessBlockConfiguration(blockPublicAccess: true) // Configure to block public access.
);

// Call the putPublicAccessBlock method to set the Block Public Access configuration and accept the returned result.
$result = $client->putPublicAccessBlock($request);

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