Mengunduh objek dari ember direktori

Contoh kode berikut menunjukkan cara membaca data dari objek dalam ember direktori dengan menggunakan AWS SDK for Java 2.x.

public static void getObject(S3Client s3Client, String bucketName, String objectKey) {
     try {
         GetObjectRequest objectRequest = GetObjectRequest
            .builder()
            .key(objectKey)
            .bucket(bucketName)
            .build();
            
         ResponseBytes GetObjectResponse objectBytes = s3Client.getObjectAsBytes(objectRequest);
         byte[] data = objectBytes.asByteArray();
         
         //Print object contents to console
         String s = new String(data, StandardCharsets.UTF_8);
         System.out.println(s);
    }
    
    catch (S3Exception e) {
        System.err.println(e.awsErrorDetails().errorMessage());
        System.exit(1);
    }
}

Contoh kode berikut menunjukkan cara membaca data dari objek dalam ember direktori dengan menggunakan AWS SDK untuk Python (Boto3).

    :return: The object data in bytes.

    try:
        response = s3_client.get_object(Bucket=bucket_name, Key=key_name)
        body = response['Body'].read()
