Amazon S3 upload file and get URL

Question

Is it possible to upload a txt/pdf/png file to Amazon S3 in a single action, and get the uploaded file URL as the response. If so, is AWS Java SDK the right library that I n

Answer 1

For AWS SDK 2+

String key = "filePath";
String bucketName = "bucketName";
PutObjectResponse response = s3Client
            .putObject(PutObjectRequest.builder().bucket(bucketName ).key(key).build(), RequestBody.fromFile(file));
 GetUrlRequest request = GetUrlRequest.builder().bucket(bucketName ).key(key).build();
 String url = s3Client.utilities().getUrl(request).toExternalForm();

Answer 2

Similarly if you want link through s3Client you can use below.

System.out.println("filelink: " + s3Client.getUrl("your_bucket_name", "your_file_key"));

Answer 3

To make the file public before uploading you can use the #withCannedAcl method of PutObjectRequest:

myAmazonS3Client.putObject(new PutObjectRequest('some-grails-bucket',  'somePath/someKey.jpg', new    File('/Users/ben/Desktop/photo.jpg')).withCannedAcl(CannedAccessControlList.PublicRead))
