Use o OSS SDK for PHP 2.0 para configurar, consultar e excluir tags de um bucket.
Nota
Os exemplos de código deste tópico usam o endpoint público da região China (Hangzhou). Para acessar o OSS a partir de outros serviços da Alibaba Cloud na mesma região, use um endpoint interno. Para obter mais informações sobre regiões e endpoints, consulte Regiões e endpoints.

Configurar tags para um bucket
O exemplo de código a seguir configura tags para um bucket:
<?php
// Automatically load objects and dependency libraries.
require_once __DIR__ . '/../vendor/autoload.php';
use AlibabaCloud\Oss\V2 as Oss;
// Specify command line parameters.
$optsdesc = [
"region" => ['help' => 'The region in which the bucket is located', 'required' => True], // The region parameter is required.
"endpoint" => ['help' => 'The domain names that other services can use to access OSS', 'required' => False], // The endpoint parameter is optional.
"bucket" => ['help' => 'The name of the bucket', 'required' => True], // The name of the bucket is required.
];
// Generate a list of long options for parsing command line parameters.
$longopts = \array_map(function ($key) {
return "$key:"; // The colon (:) following each parameter indicates that the parameter is required.
}, array_keys($optsdesc));
// Parse command line parameters.
$options = getopt("", $longopts);
// Check whether the required parameters have been configured.
foreach ($optsdesc as $key => $value) {
if ($value['required'] === True && empty($options[$key])) {
$help = $value['help'];
echo "Error: the following arguments are required: --$key, $help"; // Specifies that the required parameters are not configured.
exit(1);
}
}
// Retrieve the values of the command line parameters.
$region = $options["region"]; // Region in which the bucket is located.
$bucket = $options["bucket"]; // Name of the bucket.
// Use environment variables to load the credential information (AccessKey ID and AccessKey secret).

// Use the default configuration of the SDK.
$cfg = Oss\Config::loadDefault();
// Specify the credential provider.
$cfg->setCredentialsProvider($credentialsProvider);
// Specify the region.
$cfg->setRegion($region);
// Specify the endpoint if one is provided.
if (isset($options["endpoint"])) {
$cfg->setEndpoint($options["endpoint"]);
}
// Create an OSSClient instance.
$client = new Oss\Client($cfg);
// Create tags containing multiple key-value pairs for the bucket.
$tagging = new Oss\Models\Tagging(
tagSet: new Oss\Models\TagSet(
tags: [new Oss\Models\Tag(key: 'key1', value: 'value1'), new Oss\Models\Tag(key: 'key2', value: 'value2')]

// Create a request object for configuring tags and include the tagging information.
$request = new Oss\Models\PutBucketTagsRequest(bucket: $bucket, tagging: $tagging);

// Output the result.
printf(
'status code:' . $result->statusCode . PHP_EOL . // HTTP status code.
