How to configure tags for an object by using OSS SDK for PHP 2.0 - Object Storage Service: Central de Documentação do Alibaba Cloud

O Object Storage Service (OSS) permite configurar tags em objetos para classificá-los. Este tópico descreve como configurar tags para objetos usando o OSS SDK for PHP 2.0.

Observações de uso

Os códigos de exemplo deste tópico usam o ID da região cn-hangzhou, correspondente à região China (Hangzhou). Por padrão, o acesso aos recursos de um bucket ocorre via endpoint público. Para acessar os recursos do bucket por meio de outros serviços da Alibaba Cloud na mesma região onde ele está localizado, use um endpoint interno. Para mais informações sobre regiões e endpoints do OSS, consulte Regiões e endpoints.
Para configurar tags em um objeto, você precisa da permissão oss:PutObjectTagging. Para mais detalhes, consulte Conceder uma política personalizada.

Configurar tags durante o upload do objeto

Configurar tags durante o upload simples do objeto

O código de exemplo a seguir demonstra como configurar tags em um objeto ao fazer um upload simples:

<?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 endpoint that can be used by other services to access OSS.
    "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.
];

// Convert the parameter descriptions to a long options list required by getopt.
$longopts = \array_map(function ($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 configured.
foreach ($optsdesc as $key => $value) {
    if ($value['required'] === True && empty($options[$key])) {
        $help = $value['help']; // Obtain the help information about the parameters.
        echo "Error: the following arguments are required: --$key, $help" . PHP_EOL;
        exit(1); // If the required parameters are not configured, exit the program.
    }
}

// Obtain values from the parsed 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 object.

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

// Use the default configurations of the SDK.
$cfg = Oss\Config::loadDefault();
$cfg->setCredentialsProvider($credentialsProvider); // Specify the credential provider.
$cfg->setRegion($region); // Specify the region in which the bucket is located.
if (isset($options["endpoint"])) {
    $cfg->setEndpoint($options["endpoint"]); // Specify the endpoint if an endpoint is provided.
}

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

// Specify the content that you want to upload.
$data = 'Hello OSS';

// Create a PutObjectRequest object to upload the object.
$request = new Oss\Models\PutObjectRequest(
            bucket: $bucket,
            key: $key,
            tagging: "key1=value1&key2=value2"); // Specify the tag information.

$request-> body=Oss\Utils::streamFor($data); // Specify that the data in the HTTP request body is a binary stream.

// Perform the simple upload operation.
$result = $client->putObject($request);

// Display the upload result.
printf(
    'status code: %s' . PHP_EOL . // The HTTP status code.
    'request id: %s' . PHP_EOL . // The request ID.
    'etag: %s' . PHP_EOL, // The ETag of the object.
    $result->statusCode,
    $result->requestId,
    $result->etag
);

Configurar tags durante o upload multipart do objeto

O exemplo a seguir ilustra como configurar tags em um objeto durante um upload multipart:

<?php

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

    "endpoint" => ['help' => The domain names that other services can use to access OSS.', 'required' => False], // (Optional) Specify the endpoint that can be used by other services to access OSS.
    "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.
];

// Convert the parameter descriptions to a long options list required by getopt.
// Add a colon (:) to the end of each parameter to indicate that a value is required.

Configurar tags durante o upload por anexação do objeto

Veja abaixo um exemplo de como definir tags em um objeto durante um upload por anexação:

Adicionar ou modificar tags de um objeto existente

Se um objeto existente não tiver tags ou se elas não atenderem às suas necessidades, adicione novas tags ou modifique as atuais.
