Object Storage Service (OSS) uses a flat structure instead of a hierarchical structure that is used by traditional file systems to store objects. All data in OSS is stored as objects in buckets. To facilitate object management, the OSS console displays objects whose names end with a forward slash (/) as directories. Directories are similar to folders in file systems. You can use directories to hierarchically organize and group objects and facilitate access control.
Usage notes
In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions, endpoints and open ports.
In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Create an OSSClient instance.
Create a directory
The following sample code provides an example on how to create a directory:
<?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;
$provider = new EnvironmentVariableCredentialsProvider();
$endpoint = "yourEndpoint";
$bucket= "examplebucket";
$object = "exampledir/";
$content = "";
$options = array(
OssClient::OSS_HEADERS => array(
'x-oss-object-acl' => 'private',
'x-oss-meta-info' => 'your info'
),
);
try{
$config = array(
"provider" => $provider,
"endpoint" => $endpoint,
"signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
"region"=> "cn-hangzhou"
);
$ossClient = new OssClient($config);
$ossClient->putObject($bucket, $object, $content, $options);
} catch(OssException $e) {
printf(__FUNCTION__ . ": FAILED\n");
printf($e->getMessage() . "\n");
return;
}
print(__FUNCTION__ . "OK" . "\n");
Delete a directory
Warning
If you delete a directory, the subdirectories and all objects in the directory are synchronously deleted. We recommend that you exercise caution when you delete a directory.
The following sample code provides an example on how to delete a directory named log and all objects in the directory from a bucket named examplebucket:
<?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;
$provider = new EnvironmentVariableCredentialsProvider();
$endpoint = "yourEndpoint";
$bucket = "examplebucket";
try {
$config = array(
"provider" => $provider,
"endpoint" => $endpoint,
"signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
"region"=> "cn-hangzhou"
);
$ossClient = new OssClient($config);
$option = array(
OssClient::OSS_MARKER => null,
OssClient::OSS_PREFIX => "log/",
OssClient::OSS_DELIMITER=>'',
);
$bool = true;
while ($bool){
$result = $ossClient->listObjects($bucket,$option);
$objects = array();
if(count($result->getObjectList()) > 0){
foreach ($result->getObjectList() as $key => $info){
printf("key name:".$info->getKey().PHP_EOL);
$objects[] = $info->getKey();
}
$delObjects = $ossClient->deleteObjects($bucket, $objects);
foreach ($delObjects as $info){
$obj = strval($info);
printf("Delete ".$obj." : Success" . PHP_EOL);
}
}
if($result->getIsTruncated() === 'true'){
$option[OssClient::OSS_MARKER] = $result->getNextMarker();
}else{
$bool = false;
}
}
printf("Delete Objects : OK" . PHP_EOL);
} catch (OssException $e) {
printf("Delete Objects : Failed" . PHP_EOL);
printf($e->getMessage() . PHP_EOL);
return;
}
