This controller handles operations for upload to AWS S3.
Reference
S3.getUploadCredentials
Use this function to retrieve upload credentials for a specific media id. Use it for example if you have a batch upload and your credentials are timing out.
NOTE: This only works until S3.success is called.
If you want to start a fresh upload, please use createUploadDocument function. See Uploading to AdmiralCloud for more information.
S3.success
Make this call every time a media item has been completely uploaded to the given location.
This call also creates event for “createDownloadlink” if the upload originates from a dropsite and the dropsite is set to automatically create downloadlinks.
S3.uploadComplete
Make this call once after all media items from this batch are uploaded. Please note: If this is an upload from a Dropsite, the session will be invalidated after this call!
