s3中的文件夹结构有很多“问题”，似乎存储是扁平的。

我有一个Django项目，我需要重命名文件夹，但仍然保持目录结构不变，这意味着空文件夹也需要复制并存储在重命名的目录中。

aws cli很棒，但cp或sync或mv都没有将空文件夹(即以'/'结尾的文件)复制到新的文件夹位置，所以我使用boto3和aws cli的混合来完成任务。

或多或少我找到重命名目录中的所有文件夹，然后使用boto3将它们放在新位置，然后我用aws cli对数据进行cp，最后将其删除。

    current_property = request.session.get('property')
    if request.POST:
        # name the change
        new_name = request.POST['name']
        # old full path with www.[].com?
        old_path = request.POST['old_path']
        # remove the query string
        old_path = ''.join(old_path.split('?')[0])
        # remove the .com prefix item so we have the path in the storage
        old_path = ''.join(old_path.split('.com/')[-1])
        # remove empty values, this will happen at end due to these being folders
        old_path_list = [x for x in old_path.split('/') if x != '']

        # remove the last folder element with split()
        base_path = '/'.join(old_path_list[:-1])
        # # now build the new path
        new_path = base_path + f'/{new_name}/'
        # remove empty variables

        directory_content = default_storage.listdir(path_viewing)

        # loop over folders and add them by default, aws cli does not copy empty ones
        # so this is used to accommodate
        folders, files = directory_content
        for folder in folders:
            new_key = new_path+folder+'/'
            # we must remove bucket name for this to work
            new_key = new_key.split(f"{bucket}/")[-1]
            # push this to new thread
            threading.Thread(target=put_object, args=(client, bucket, new_key,)).start()

        messages.success(request, f'Folder Renamed to: {new_name}')

    return redirect(request.META.get('HTTP_REFERER', f"{reverse('home', args=[client_url])}"))

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}",
));

您可以使用AWS CLI命令来mv文件

我所做的是创建一个新文件夹，并将旧的files对象移动到新文件夹。

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;
    }
}

要重命名文件夹(从技术上讲，文件夹是一组对象，以公共前缀作为键)，您可以使用aws CLI move命令带——recursive选项。

aws s3 mv s3://bucket/old_folder s3://bucket/new_folder --recursive
