问题
is it possible to have a catch-all for unrecognized user entries to move the user into a particular story?
For example in a conversation. If there are no matching stories the bot will respond to try and push the user back on track?
[user] Hi how are you
[bot] good, how are you?
[user] great
[bot] that is good
--- user enters an un-matched sentence ---
[bot] I did not understand you. Would you like to order a pizza?
[user] yes
...etc
回答1:
I don't know if it's the best solution but I do the following:
1) Create a story without intent to catch the "no matching stories".
2) The bot answers: "I did not understand you. Would you like to order a pizza?"
3) Yes/No handling https://wit.ai/docs/recipes#handle-yesno-answers
4) If yes, create an action call "jumpToPizzaOrderingStory". On your side, this action "emulates" the fact that the users sent "I want to order a pizza" that will triggered your PizzaOrdering story.
