Get Query Params

[RahulT1008]

Can anyone help me to get query params from the requested URL in the delegate function ?

like this is my URL : http://localhost:8182/iiif/2/video-3.png/info.json?config_id=12345

I have enabled Delegate Script

here is my filesystemsource_pathname method (delegates.rb) where i want to get query params

def filesystemsource_pathname(options = {})
    logger = Java::edu.illinois.library.cantaloupe.delegate.Logger
    identifier = context['identifier']
    
    dam = '/home/integrated/images/'    
    
    file_path = File.join(dam, identifier)
    return file_path

end

I simply want to get config_id from the URL, is possible to get it ?
