It is recommended that you use rasa as an HTTP service, so that you can use the interface of rasa flexibly.

First, preprocess message, then, use [http://localhost:5005/model/parse] to parse message, use [http://localhost:5005/conversations/{conversation_id}/messages] to change the tracker. use [http://localhost:5005/conversations/{conversation_id}/predict] to predict next action.

Create a custom nlu component at the very beginning of your pipeline.
