显示由微调器上传到 Amazon S3 的图像

我已经按照本教程 http://blog.fineuploader.com/2013/08/16/fine-uploader-s3-upload-directly-to-amazon-s3-from-your-browser/使用fineuploader将图像上传到Amazon S3，并且上传工作正常。问题是当我想查看已上传到 S3 的图片时。

我收到错误

[06-Jan-2015 12:30:19 Europe/Berlin] PHP Fatal error:  Uncaught Aws'S3'Exception'AccessDeniedException: AWS Error Code: AccessDenied, Status Code: 403, AWS Request ID: 6F9935EA1BE9F4F5, AWS Error Type: client, AWS Error Message: Access Denied, User-Agent: aws-sdk-php2/2.7.12 Guzzle/3.9.2 curl/7.24.0 PHP/5.3.28 ITR
  thrown in /home/connecti/public_html/aws/Aws/Common/Exception/NamespaceExceptionFactory.php on line 91

当我运行此测试考试时

<?php
require 'aws/aws-autoloader.php';
use Aws'S3'S3Client;
// Instantiate the S3 client with your AWS credentials
$s3 = S3Client::factory(array(
'key' => 'MY_KEY',
'secret' => 'MY_SECRET_KEY',
));

$bucket = 'MY_BUCKET';
// Use the high-level iterators (returns ALL of your objects).
$objects = $s3->getIterator('ListObjects', array('Bucket' => $bucket));
echo "Keys retrieved!'n";
foreach ($objects as $object) {
    echo $object['Key'] . "'n";
}
// Use the plain API (returns ONLY up to 1000 of your objects).
$result = $s3->listObjects(array('Bucket' => $bucket));
echo "Keys retrieved!'n";
foreach ($result['Contents'] as $object) {
    echo $object['Key'] . "'n";
}
?>

我的密钥、密钥和存储桶是正确的！

与其他示例相同。

我需要做什么？谁能给我一个例子，我如何显示由fineuploader上传的图像，以及我是否必须在亚马逊上进行任何设置（除了我从fineuploader博客所做的工作）？
