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

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。

我刚刚测试了这个，它是有效的:

aws s3 --recursive mv s3://<bucketname>/<folder_name_from> s3://<bucket>/<folder_name_to>

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
