Alexa Skill python 无法与 NoIntent 一起正常工作

Question

我是 Alexa Skill 和 Python 的基础开发人员，但无法理解问题出在哪里。 此技能询问淋浴的开始和结束时间，以计算费用和能源消耗。

当用户完成淋浴时，我问“Alexa 洗澡”而不是 Alexa 问：

• 你洗完澡了吗？ （“是的”）
• 你用过电吹风吗？

当用户对最后一个问题回答“否”时，Alexa 不理解。 相反，当答复是“是”时，一切都很好。

代码有什么问题？ 谢谢

记录器信息 ("inside YesIntentHandler()") # 类型：(HandlerInput) -> 响应分钟) + 5 ) * 0.07 userId = handler_input.request_envelope.context.system.user.user_id print(userId) item = {
