Question

我想在会话开始时收集用户名，并且我尝试使用某些帖子中建议的“ action_session_start”来实现。我还没有部署。我正在使用“ rasa shell”和“ rasa x”来查看结果我进行了操作，有一个“用户名”插槽，还有“ utter_ask_username”模板。但是Bot不会使用此操作中的任何内容，而是等待用户输入，即使在第一次输入之后，它也不会询问用户名。我究竟做错了什么。您能否分享一些Bot提出一些问题来填补空缺的示例。谢谢

class ActionSessionStart(Action):
    def name(self) -> Text:
        return "action_session_start"

    @staticmethod
    def fetch_slots(tracker: Tracker) -> List[EventType]:
        """Collect slots that contain the user's name and phone number."""

        slots = []
        logger.info("keeping only name/phone_number slots")
        for key in ("username"):
            value = tracker.get_slot(key)
            if value is not None:
                slots.append(SlotSet(key=key, value=value))
        return slots

    async def run(
      self, dispatcher, tracker: Tracker, domain: Dict[Text, Any]
    ) -> List[Dict[Text, Any]]:
        # the session should begin with a `session_started` event
       
        events = [SessionStarted()]

        # any slots that should be carried over should come after the
        # `session_started` event
        events.extend(self.fetch_slots(tracker))

        # an `action_listen` should be added at the end as a user message follows
        events.append(ActionExecuted("action_listen"))

        return events
