Multiple s3 buckets in Filepicker.io - filepicker.io

Question

I need to upload to multiple s3 buckets with filepicker.io. I found a tweet that indicated that there was a hacky, but possible, way to do this. Support hasn't gotten back to me yet, so I'm hoping that someone here already knows the answer!

Answer 1

Have you tried generating a second application/API key? It looks like they lock your S3/AWS credentials to an application/API key rather than directly to the account.

Answer 2

Support just got back to me. There's no way to do this besides creating multiple applications, which is okay if you are just switching between prod/staging/dev, but not a good solution if you have to upload to arbitrary buckets.
My solution is to execute a PUT request with the x-amz-copy-source header after the file has been uploaded, which copies it to the correct bucket.
This is pretty hacky as it request two extra requests per file -- one filepicker.stat and one more call to s3 (or your server).

#Ben
I am developing code with same issue of files needing to go into many buckets. I'm working in ASP.net.
What I have done is have one Filepicker 'application' with it's own S3 bucket.
I already had a callback to the server in the javascript onSuccess() function (which is passed as a parameter to filepicker.store()). This callback needed to be there to do some book-keeping anyway.
So I have just added in an extra bit to the server-side callback code which uses the AWS SDK to copy the object from the bucket filepicker uploades it to, to it's final destination bucket.
This is my C# code for moving, or rather copying, an object between buckets:
public bool MoveObject(string bucket1, string key1, string bucket2, string key2 = null)
{
bool success = false;
if (key2 == null) key2 = key1;
Logger logger = new Logger(); // my logging system
try
{
RegionEndpoint region = RegionEndpoint.EUWest1; // use your region here
using (AmazonS3Client s3Client = new AmazonS3Client(region))
{
// TODO: CheckForBucketFunction
CopyObjectRequest request = new CopyObjectRequest();
request.SourceBucket = bucket1;
request.SourceKey = key1;
request.DestinationBucket = bucket2;
request.DestinationKey = key2;
S3Response response = s3Client.CopyObject(request);
logger.Info2Log("response xml = \n{0}\n", response.ResponseXml);
response.Dispose();
success = true;
}
}
catch (AmazonS3Exception ex)
{
logger.Info2Log("Error copying file between buckets: {0} - {1}",
ex.ErrorCode, ex.Message);
success = false;
}
return success;
}
There are AWS SDKs for other server languages and the good news is Amazon doesn't charge for copying objects between buckets in the same region.
Now I just have to decide how to delete the object from the filepicker application bucket. I could do it on the server using more AWS SDK code but that will be messy as it leaves links to the object in the filepicker console. Or I could do it from the browser using filepicker code.
