我正在尝试获取Object存储桶中特定文件夹下的列表。
I know that to get a list of all of my objects I do:
我知道要获取我所做的所有对象的列表：
$objects = $client->getIterator('ListObjects', array(
'Bucket' => $bucket
));
I want to get only the objects under the folder my/folder/test. I have tried adding
我只想获取文件夹下的对象my/folder/test。我试过添加
'key' => "my/folder/test",
And
和

But it simply returns all of the objects in my bucket.
但它只是返回我存储桶中的所有对象。

You need to use Prefixto restrict the search to a specific directory (a common prefix).
您需要使用Prefix将搜索限制在特定目录（公共前缀）。
$objects = $client->getIterator('ListObjects', array(
"Bucket" => $bucket,
"Prefix" => "your-folder/"
));

The answer is above however i figured i would supply a complete working example that can be copied and pasted directly into a php file and ran
答案在上面，但是我想我会提供一个完整的工作示例，可以将其直接复制并粘贴到 php 文件中并运行
use Aws\S3\S3Client;
require_once('PATH_TO_API/aws-autoloader.php');
$s3 = S3Client::factory(array(
'key' => 'YOUR_KEY',
'secret' => 'YOUR_SECRET',
'region' => 'us-west-2'
));
$bucket = 'YOUR_BUCKET_NAME';
$objects = $s3->getIterator('ListObjects', array(
"Bucket" => $bucket,
"Prefix" => 'some_folder/' //must have the trailing forward slash "/"
));
foreach ($objects as $object) {
echo $object['Key'] . "<br>";
}

"S3Client::factory is deprecated in SDK 3.x, otherwise the solution is valid" said by RADU
“S3Client::factory 在 SDK 3.x 中被弃用，否则解决方案是有效的” RADU 说
Here is the updated solution to help others who come across this answer:
这是更新的解决方案，以帮助遇到此答案的其他人：
# composer dependencies
require '/vendor/aws-autoloader.php';
//AWS access info DEFINE command makes your Key and Secret more secure
if (!defined('awsAccessKey')) define('awsAccessKey', 'ACCESS_KEY_HERE');/// <- put in your key instead of ACCESS_KEY_HERE
if (!defined('awsSecretKey')) define('awsSecretKey', 'SECRET_KEY_HERE');/// <- put in your secret instead of SECRET_KEY_HERE
use Aws\S3\S3Client;
$config = [
's3-access' => [
'key' => awsAccessKey,
'secret' => awsSecretKey,
'bucket' => 'bucket',
'region' => 'us-east-1', // 'US East (N. Virginia)' is 'us-east-1', research this because if you use the wrong one it won't work!
'version' => 'latest',
'acl' => 'public-read',
'private-acl' => 'private'
]
];
# initializing s3
$s3 = Aws\S3\S3Client::factory([
'credentials' => [
'key' => $config['s3-access']['key'],
'secret' => $config['s3-access']['secret']
],
'version' => $config['s3-access']['version'],
'region' => $config['s3-access']['region']
]);
$bucket = 'bucket';
$objects = $s3->getIterator('ListObjects', array(
"Bucket" => $bucket,
"Prefix" => 'filename' //must have the trailing forward slash for folders "folder/" or just type the beginning of a filename "pict" to list all of them like pict1, pict2, etc.
));
foreach ($objects as $object) {
echo $object['Key'] . "<br>";
}
