In my application I will get the url of s3 file like : https://s3.amazonaws.com/account-update/input.csv I have to download it and then process it. What I already done :
AmazonS3 s3 = new AmazonS3Client(credentials);
S3Object s3object = s3.getObject(new GetObjectRequest(
bucketName, key));
I am able to download the file by providing bucket name and key, but how can I download the file using the url(https://s3.amazonaws.com/account-update/input.csv) only?
Just enter the url on the browser but make sure to replace \u0026 with & if you have downloaded the url via curl else you will get this error
<Error> <Code>AuthorizationQueryParametersError</Code> <Message>X-Amz-Algorithm only supports "AWS4-HMAC-SHA256"</Message> </Error>
You can't, but you can make the file attachment in the upload.
For example:
ObjectMetadata objectMetadata = new ObjectMetadata();
objectMetadata.setContentType("application/csv;charset=utf-8");
objectMetadata.setContentDisposition("attachment");
PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, arquivo, file, objectMetadata).withCannedAcl(CannedAccessControlList.PublicRead);
amazonS3.putObject(putObjectRequest);
I hope it helps.
