有一种软件可以使用s3桶执行不同类型的操作。

软件名称:S3浏览器

S3浏览器是Amazon S3和Amazon CloudFront的免费Windows客户端。Amazon S3提供了一个简单的web服务接口，可用于在任何时间、从web上的任何地方存储和检索任意数量的数据。Amazon CloudFront是一个内容分发网络(CDN)。它可用于使用边缘位置的全球网络交付您的文件。

如果只有一次，那么你可以使用命令行执行这些操作:

(1)重命名同一桶内的文件夹:

s3cmd --access_key={access_key} --secret_key={secret_key} mv s3://bucket/folder1/* s3://bucket/folder2/

(2)重命名Bucket:

s3cmd --access_key={access_key} --secret_key={secret_key} mv s3://bucket1/folder/* s3://bucket2/folder/

在那里,

{access_key} = s3客户端的有效访问密钥

{secret_key} = s3客户端的有效密匙

它工作得很好，没有任何问题。

谢谢

文件和文件夹实际上是S3中的对象。你应该使用PUT OBJECT COPY来重命名它们。参见http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html

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

下面是重命名s3上文件的代码示例。由于spark o/p文件，我的文件是part-000*，然后我将其复制到相同位置的另一个文件名，并删除part-000*:

import boto3
client = boto3.client('s3')
response = client.list_objects(
Bucket='lsph',
MaxKeys=10,
Prefix='03curated/DIM_DEMOGRAPHIC/',
Delimiter='/'
)
name = response["Contents"][0]["Key"]
copy_source = {'Bucket': 'lsph', 'Key': name}
client.copy_object(Bucket='lsph', CopySource=copy_source, 
Key='03curated/DIM_DEMOGRAPHIC/'+'DIM_DEMOGRAPHIC.json')
client.delete_object(Bucket='lsph', Key=name)

S3DirectoryInfo有一个MoveTo方法，它将把一个目录移动到另一个目录，这样移动的目录将成为另一个目录的子目录，其名称与原来的目录相同。

下面的扩展方法将一个目录移动到另一个目录，即移动的目录将成为另一个目录。它实际上所做的是创建新目录，将旧目录中的所有内容移到该目录中，然后删除旧目录。

public static class S3DirectoryInfoExtensions
{
    public static S3DirectoryInfo Move(this S3DirectoryInfo fromDir, S3DirectoryInfo toDir)
    {
        if (toDir.Exists)
            throw new ArgumentException("Destination for Rename operation already exists", "toDir");
        toDir.Create();
        foreach (var d in fromDir.EnumerateDirectories())
            d.MoveTo(toDir);
        foreach (var f in fromDir.EnumerateFiles())
            f.MoveTo(toDir);
        fromDir.Delete();
        return toDir;
    }
}

我们有两种方法可以重命名AWS S3存储上的文件-

1 .使用CLI工具-

Aws s3——递归mv s3://bucket-name/dirname/oldfile s3://bucket-name/dirname/newfile

2.使用SDK

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