Amazon S3中是否有重命名文件和文件夹的功能?欢迎提出相关建议。


当前回答

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

其他回答

如果您想重命名s3文件夹中的许多文件,可以运行以下脚本。

    FILES=$(aws s3api list-objects --bucket your_bucket --prefix 'your_path' --delimiter '/'  | jq -r '.Contents[] | select(.Size > 0) | .Key' | sed '<your_rename_here>')
     for i in $FILES
     do
      aws s3 mv s3://<your_bucket>/${i}.gz s3://<your_bucket>/${i}
     done   

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}",));

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。

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

package com.bighalf.doc.amazon;

    boolean result = false;
    try {

            //updating child folder location with the newlocation

            if(key.charAt(key.length()-1)=='/'){
                //if name ends with suffix (/) means its a folders
                PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, destinationKeyName, emptyContent, metadata);

                s3client.copyObject(copyObjRequest);
            }
        }
        boolean isFodlerDeleted = deleteFolderFromAws(bucketName, keyName);
        return isFodlerDeleted;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return result;
}

public static boolean deleteFolderFromAws(String bucketName, String keyName) {
    boolean result = false;
    try {
        AmazonS3 s3client = getAmazonS3ClientObject();
        //deleting folder children
        List<S3ObjectSummary> fileList = s3client.listObjects(bucketName, keyName).getObjectSummaries();

            s3client.deleteObject(bucketName, file.getKey());
        }
        //deleting actual passed folder
        s3client.deleteObject(bucketName, keyName);
        result = true;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return result;
}

public static void main(String[] args) {
    intializeAmazonObjects();
    boolean result = renameAwsFolder(bucketName, keyName, newName);
    System.out.println(result);
}

private static AWSCredentials credentials = null;
private static AmazonS3 amazonS3Client = null;
private static final String ACCESS_KEY = "";
private static final String SECRET_ACCESS_KEY = "";
private static final String bucketName = "";
private static final String keyName = "";
//renaming folder c to x from key name
private static final String newName = "";

public static void intializeAmazonObjects() {
    credentials = new BasicAWSCredentials(ACCESS_KEY, SECRET_ACCESS_KEY);
    amazonS3Client = new AmazonS3Client(credentials);
}

public static AmazonS3 getAmazonS3ClientObject() {
    return amazonS3Client;
}

}

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>
