Upload file to S3 using filepicker.io and replace whitespace - filepicker.io

Question

I've been uploading files to the amazon s3 using the javascript library filepicker.io and the implementation works ok, the problem I'm facing now is that when users upload files with white spaces or fancy characters those files are not accessible through http, i was wondering if there is any way to apply some kind of renaming to the file prior the uploading face.
I'm using the pickAndStore method from the filepicker.io api
filepicker.pickAndStore({
mimetype: ['video/*'],
services:['COMPUTER', 'DROPBOX', 'GOOGLE_DRIVE', 'BOX', 'URL', 'VIDEO', 'FTP'],
},{location: 's3'},function(fpfiles){
fpfile = fpfiles[0];
$('#temp_file_url').val('/' + fpfile.key);
});
Thanks.

Answer 1

You can specify a "path" parameter in both the filepicker.store() call and filepicker.pickAndStore(), so if you want to specifically strip the whitespace from the filenames but keep the rest the same, the structure would be:
filepicker.pick({...options...}, function(fpfile){
var new_name = process(fpfile.filename);
filepicker.store(new_name,
{path: new_name, filename: new_name}, function(){});
});

Answer 2

You can also use path on pickAndStore but you won't be able to preprocess the inkblob.
