如何使用 AWS PHP 开发工具包在 JSON 中检索 Amazon S3 存储桶的内容

使用适用于 PHP v2 的官方 AWS 开发工具包，您可以执行以下操作：

<?php
require 'vendor/autoload.php';
use Aws'Common'Aws;
// Instantiate an S3 client
$s3 = Aws::factory('/path/to/config.php')->get('s3');
$objects = $s3->getIterator('ListObjects', array(
    'Bucket' => $bucket
));
foreach ($objects as $object) {
    echo $bucket['Name'] . '/' . $object['Key'] . PHP_EOL;
}

1. 它对我来说工作正常，除了MaxKeys被忽略了。

2. 使用上述方法和以下方法有区别吗？虽然我无法在$result内找到数组元素.

   use Aws'Common'Aws;
   use Aws'S3'S3Client;
   // Prepare S3 Client to speak with AWS
   $s3client;
   $s3client = S3Client::factory(array(
       'key' => '',
       'secret' => '',
       'region' => Region::US_EAST_1
   ));
   // List objects from a bucket
   $result = $s3client->listObjects(array(
       'Bucket' => $aws_bucket,
       'MaxKeys' => 25,
       'Marker' => 'docs/'
   ));
   $objects = $result->getIterator();
   foreach ($objects as $wo)
   {
       // Prints junk
       echo $wo['Key'] . ' - ' . $wo['Size'] . PHP_EOL;
   }
