How to get confidence of action in conversation?

[AnonymousArthur]

Like the confidence value showing in Wit.ai Log tab, I want to response unknow message when the confidence is too low.

If you use the dev-master version you can get the confidence from the step $step->getConfidence(). This feature was implemented here: https://github.com/tgallice/wit-php/pull/24/files
If you have an older version take care to the BC.

In the abstract class ActionMapping, I have action interface like this:
abstract public function action($sessionId, $actionName, Context $context, array $entities = []);
It doesn't have $step parameter. So weird.

I see why, composer use 0.3.1 version which doesn't have this feature. I'll reinstall the package. Thank you very much!
