How to get the object url with alias name from aws s3 using CloudFront - ruby-on-rails

Question

I am uploading files with unique id like 'd9127dfd01182afe7d34a37' as object name to amazon s3 and storing the file information with my local database including original name of the file. And I am using CloudFront url to download the file.
If I download the file using CloudFront url file name is d9127dfd01182afe7d34a37. But I need to change file name again to it's original name wich I have in my database. I don't want to download it. I want to give the url with original name to the client(WebUI) and client can download it through url.
serverside code
document_url = initialize_cloud_service(document.provider['primary']).get_object_url(document_id, expires_at, 'CloudFront' )
if document_url
item = {}
item['id'] = document['_id'].to_s
item['name'] = document['name']
item['mime_type'] = document['mime_type']
item['url'] = document_url
return {success: true, message: MESSAGES['get_url_succuss'],data: item}.to_json
end
client side code
download: function(response){
file = response.data
link = document.createElement('a');
link.download = file.name;
link.href = file.url;
link.click();
},
Is there any way to achieve this? Please help me out. I am using ruby on rails and mongodb as local database.
Thanks

Answer 1

I have achieved by doing the following changes
Server Side code
begin
expires_at = Time.now.to_i + 30.seconds.to_i
options = nil
selected_provider = provider || document.provider['primary']
case selected_provider
when "s3"
options = {"response-content-disposition" => "attachment; filename=#{document['name']}"}
downloadable_url = initialize_cloud_service(selected_provider).get_downloadable_url(document_id, expires_at, options)
when "google_cloud"
downloadable_url = initialize_cloud_service(selected_provider).get_downloadable_url(document_id, expires_at, options)
downloadable_url += "&response-content-disposition=attachment%3B%20filename%3D#{document['name']}"
end
item = {}
item['id'] = document['_id'].to_s
item['name'] = document['name']
item['mime_type'] = document['mime_type']
item['url'] = downloadable_url
return {success: true, message: MESSAGES['get_url_succuss'],data: item}.to_json
rescue Exception => e
puts 'Exception in download, message: ' + e.message
return {success: false, message: MESSAGES['default']}.to_json
end
client side code
download: function(response){
var hiddenIFrameID = 'hiddenDownloader',
iframe = document.getElementById(hiddenIFrameID);
if (iframe === null) {
iframe = document.createElement('iframe');
iframe.id = hiddenIFrameID;
iframe.style.display = 'none';
document.body.appendChild(iframe);
}
iframe.src = response.data.url;
},
