正如Naaz所回答的，直接重命名s3是不可能的。

我附上了一个代码片段，它将复制所有的内容

代码正在工作，只需添加您的aws访问密钥和秘密密钥

这是我在代码中所做的

->复制源文件夹内容(嵌套子和文件夹)并粘贴到目标文件夹

->拷贝完成后，删除源文件夹

我刚把它弄好了。你可以像这样使用AWS SDK:

use Aws\S3\S3Client;

$sourceBucket = '*** Your Source Bucket Name ***';
$sourceKeyname = '*** Your Source Object Key ***';
$targetBucket = '*** Your Target Bucket Name ***';
$targetKeyname = '*** Your Target Key Name ***';        

// Instantiate the client.
$s3 = S3Client::factory();

// Copy an object.
$s3->copyObject(array(
    'Bucket'     => $targetBucket,
    'Key'        => $targetKeyname,
    'CopySource' => "{$sourceBucket}/{$sourceKeyname}",
));

http://docs.aws.amazon.com/AmazonS3/latest/dev/CopyingObjectUsingPHP.html

下面是你如何在。net中使用S3 .NET SDK:

var client = new Amazon.S3.AmazonS3Client(_credentials, _config);
client.CopyObject(oldBucketName, oldfilepath, newBucketName, newFilePath);
client.DeleteObject(oldBucketName, oldfilepath);

附注:尽可能使用“异步”版本的客户端方法，尽管我没有这样做是为了可读性

这是现在可能的文件，选择文件，然后选择操作>重命名在GUI。

要重命名文件夹，你必须创建一个新文件夹，并选择旧文件夹的内容并复制/粘贴它(再次在“操作”下)

S3中没有重命名文件的直接方法。你所要做的就是复制现有文件的新名称(只要设置目标键)，然后删除旧的。
