如何在Amazon S3存储桶中重命名文件？ [英] How to rename a file in Amazon S3 Bucket?

问题描述

我正在尝试重命名S3存储桶中的文件。这是一个代码段

I am trying to rename a file in S3 Bucket. Here is a code snippet

    S3Object s3Obj  = getS3Client().getObject(new GetObjectRequest(getBucketName(), fileName));  
//Error in Above Line itself            
    getS3Client().putObject(getBucketName(), newFileName, s3Obj.getObjectContent(), s3Obj.getObjectMetadata());

private AmazonS3 getS3Client(){
        AWSCredentials myCredentials = new BasicAWSCredentials(AccessKey,SecretKey);
        AmazonS3 s3client = new AmazonS3Client(myCredentials);
        return s3client;
}

所以，我收到此错误，

调试[main] request.handleErrorResponse（748）|收到的错误响应：com.amazonaws.services.s3.model.AmazonS3Exception：状态代码：403，AWS服务：空，AWS请求ID：AD2F31F1133A650E，AWS错误代码：AccessDenied。

DEBUG [main] request.handleErrorResponse(748) | Received error response: com.amazonaws.services.s3.model.AmazonS3Exception: Status Code: 403, AWS Service: null, AWS Request ID: AD2F31F1133A650E, AWS Error Code: AccessDenied.

我无法获取s3object本身。我将如何获得S3对象并将其重命名的任何建议或想法。
感谢您的帮助。

I am unable to get the s3object itself. Any suggestions or ideas how I will get S3 Object and rename it. Thanks in Anticipation for you help.

推荐答案

直接重命名S3对象不可能

通过复制并删除原始对象来重命名对象

Rename objects by copying them and deleting the original ones

您可以使用例如

CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName, 
           keyName, bucketName, destinationKeyName);
s3client.copyObject(copyObjRequest);
s3client.deleteObject(new DeleteObjectRequest(bucketName, keyName));
