从 AWS Java SDK 2.0 中的 GetObjectResponse 获取 S3Object

Question

In AWS Java SDK 1.x, I could get an S3Object from an S3Client like this.

S3Object obj = mS3Client.getObject(pBucket, pKey);

I'm trying to replicate that functionality using AWS Java SDK 2.0 (and end up with an S3Object ), but the closest I can get is a GetObjectResponse , and I can't find any simple method calls to turn the response into an S3Object .

GetObjectResponse response = mS3Client.getObject(
        GetObjectRequest.builder()
                .bucket(pBucket)
                .key(pKey)
                .build())
        .response();

How can I get an S3Object from the 2.0 S3Client , or build one from the GetObjectResponse ?

use ResponseInputStream. Hope the below code solves your problem.

GetObjectRequest request = GetObjectRequest.builder()
    .bucket("BucketName")
    .key("key")
    .build();
ResponseInputStream<GetObjectResponse> s3objectResponse = s3Client
    .getObject(request);
BufferedReader reader = new BufferedReader(new InputStreamReader(s3objectResponse));

String line;            
while ((line = reader.readLine()) != null) {            
    System.out.println(line);
}
