Comment renommer un fichier dans Amazon S3 Bucket?

Question

J'essaie de renommer un fichier dans S3 Bucket. Voici un extrait de code

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; 
} 

Donc, je reçois cette erreur,

DEBUG [principal] request.handleErrorResponse (748) | Réponse d'erreur reçue: com.amazonaws.services.s3.model.AmazonS3Exception: code d'état: 403, service AWS: nul, ID de requête AWS: AD2F31F1133A650E, code d'erreur AWS: AccessDenied.

Je n'arrive pas à obtenir l'objet s3object lui-même. Toutes les suggestions ou idées comment je vais obtenir l'objet S3 et le renommer. Merci d'avance pour votre aide.

Answer 1

renommage direct des objets S3 is not possible

Renommer des objets en les copiant et en supprimant celles d'origine

Vous pouvez copier et supprimer à l'aide par exemple

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

Answer 2

Comme répondu par High6 renommage direct de s3 n'est pas possible, mais son code ne sera pas copier tout le contenu

Je joins un extrait de code qui permet de copier tout le contenu

Code

est ajoutez votre travail justes aws clé d'accès et clé secrète

est ici ce que je l'ai fait dans le code

-> copier le contenu du dossier source (enfant imbriqué et les dossiers) et collés dans le dossier de destination

-> lorsque la copie est terminée, supprimez le dossier source
