How to access S3 object using S3 object ARN using java

Question

Client will send a S3 object URL(ARN) using my API. The object is a JSON file. How to access the object using ARN using java

Answer 1

You can retrieve the bucket name and the object name from the JSON and use these values to get the object. For example, assume you want to read the byte[] of the object. Using the Amazon S3 Java API V2, you can perform this use case:

public static void getObjectBytes (S3Client s3, String bucketName, String keyName, String path ) {
    
           GetObjectRequest objectRequest = GetObjectRequest
                    .builder()
                    .key(keyName)
                    .bucket(bucketName)
                    .build();
    
          ResponseBytes<GetObjectResponse> objectBytes = s3.getObjectAsBytes(objectRequest);
          byte[] data = objectBytes.asByteArray();
    
// more logic
}
