Los objetos Archive, Cold Archive y Deep Cold Archive deben restaurarse antes de poder leerlos. En este tema se describe cómo restaurar objetos Archive y Cold Archive.
Notas
Solo los objetos Archive, Cold Archive y Deep Cold Archive admiten la operación RestoreObject.
En este tema se utiliza el endpoint público de la región China (Hangzhou). Para acceder a OSS desde otros servicios de Alibaba Cloud en la misma región, use un endpoint interno. Para obtener más información sobre las regiones y los endpoints compatibles, consulte Regions and endpoints.
Este tema muestra cómo crear una instancia de OSSClient con un endpoint de OSS. Para conocer configuraciones alternativas, como usar un dominio personalizado o autenticarse con credenciales de Security Token Service (STS), consulte Create an OssClient.
Para restaurar un archivo, debe contar con el permiso
oss:RestoreObject. Para obtener más información, consulte Grant custom permissions to a RAM user.
Restaurar un objeto Archive
A continuación se muestra el código para restaurar un objeto Archive:
<?php
if (is_file(__DIR__ . '/../autoload.php')) {
require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
require_once __DIR__ . '/../vendor/autoload.php';
}
use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;
// Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set.
$provider = new EnvironmentVariableCredentialsProvider();
// The Endpoint is set to the China (Hangzhou) region. Replace it with the actual Endpoint.
$endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// Specify the bucket name. Example: examplebucket.
$bucket= "examplebucket";
// Specify the full path of the Archive object. Do not include the bucket name. Example: srcexampleobject.txt.
$object = "srcexampleobject.txt";
try {
$config = array(
"provider" => $provider,
"endpoint" => $endpoint,
"signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
"region"=> "cn-hangzhou"
);
$ossClient = new OssClient($config);
// Restore the file.
$ossClient->restoreObject($bucket, $object);
} catch (OssException $e) {
printf(__FUNCTION__ . ": FAILED\n");
printf($e->getMessage() . "\n");
return;
}
print(__FUNCTION__ . ": OK" . "\n"); Restaurar un objeto Cold Archive
A continuación se muestra el código para restaurar un objeto Cold Archive:
<?php
if (is_file(__DIR__ . '/../autoload.php')) {
require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
require_once __DIR__ . '/../vendor/autoload.php';
}
use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;
use OSS\Model\RestoreConfig;
// Obtain access credentials from environment variables. Before you run this sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are set.
$provider = new EnvironmentVariableCredentialsProvider();
// The Endpoint is set to the China (Hangzhou) region. Replace it with the actual Endpoint.
$endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// Specify the bucket name. Example: examplebucket.
$bucket= "examplebucket";
// Specify the full path of the Cold Archive object. Do not include the bucket name. Example: srcexampleobject.txt.
$object = "srcexampleobject.txt";
try {
$config = array(
"provider" => $provider,
"endpoint" => $endpoint,
"signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
"region"=> "cn-hangzhou"
);
$ossClient = new OssClient($config);
// The number of days for which the object remains in the restored state. Valid values: 1 to 7.
$day = 3;
// The restoration priority. This is set to Bulk, which means the object is restored within 5 to 12 hours.
// To restore the object within 2 to 5 hours, set this parameter to Standard. To restore the object within 1 hour, set this parameter to Expedited.
$tier = "Bulk";
$config = new RestoreConfig($day,$tier);
$options = array(
OssClient::OSS_RESTORE_CONFIG => $config
);
$result = $ossClient->restoreObject($bucket, $object,$options);
} catch (OssException $e) {
printf($e->getMessage() . "\n");
return;
