無法在S3中將文件從一個文件夾移動到另一個文件夾

Question

我想將S3文件夾內的文件移動到同一s3存儲桶中的另一個文件夾。 我嘗試了以下代碼

CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName,
                                              srcFolder+"/"+Filename, bucketName, 
                                              targetFolder+"/"+Filename);
s3Client.copyObject(copyObjRequest);
DeleteObjectRequest deleteObjRequest = new DeleteObjectRequest(bucketName, 
                                                        srcFolder+"/"+Filename);
s3Client.deleteObject(deleteObjRequest);

該文件夾可能包含多個文件，我只想移動選定的文件。 上面的代碼沒有顯示任何錯誤，但是什么也沒有發生。 誰能為我建議正確的解決方案。

只需運行以下代碼並檢查輸出是什么（不帶和刪除），這將是一個很好的初始選擇。

同樣值得檢查對象的ACL和存儲桶策略。

這是預期的格式

CopyObjectRequest(java.lang.String sourceBucketName, java.lang.String sourceKey, java.lang.String destinationBucketName, java.lang.String destinationKey)

如果要在同一存儲桶中復制對象

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myBucket", "myNewObject.txt");
s3Client.copyObject(copyObjRequest);

如果要在另一個存儲桶中復制對象

CopyObjectRequest copyObjRequest = new CopyObjectRequest("myBucket", "myObject.txt", "myOtherBucket", "myNewObject.txt");
s3Client.copyObject(copyObjRequest);

測試樣本代碼

import java.io.IOException;

import com.amazonaws.AmazonServiceException;
import com.amazonaws.SdkClientException;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.CopyObjectRequest;

public class CopyObjectSingleOperation {

    public static void main(String[] args) throws IOException {
        String clientRegion = "*** Client region ***";
        String bucketName = "*** Bucket name ***";
        String sourceKey = "*** Source object key *** ";
        String destinationKey = "*** Destination object key ***";

        try {
            AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                    .withCredentials(new ProfileCredentialsProvider())
                    .withRegion(clientRegion)
                    .build();

            // Copy the object into a new object in the same bucket.
            CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName, sourceKey, bucketName, destinationKey);
            s3Client.copyObject(copyObjRequest);
        }
        catch(AmazonServiceException e) {
            // The call was transmitted successfully, but Amazon S3 couldn't process 
            // it, so it returned an error response.
            e.printStackTrace();
        }
        catch(SdkClientException e) {
            // Amazon S3 couldn't be contacted for a response, or the client  
            // couldn't parse the response from Amazon S3.
            e.printStackTrace();
        }
    }
}
