我是一名相对较不熟悉Python编程的大学生。我一直在尝试构建一个对话式机器人，该机器人使用户可以通过Python中的SMS安排约会。
我一直在网上关注许多Python Twilio SMS教程，例如official Twilio指南。我无法弄清楚如何将Twilio SMS响应路由到相应的路由。例如，假设用户以SCHEDULE，RESCHEDULE，CHECK或DROP的文本形式发送消息，而应用程序则应将它们路由到相应的路由逻辑来处理请求（并用进一步的SMS消息回复）。如果他们没有输入四个指定单词之一，则应用程序应该将用户重新路由到/inbound路由，以要求他们再次说明他们正在选择四个可接受的选项之一。在过去的几天里，我确实一直在努力工作，对routes和是否使用message = client.messages.create或response = MessagingResponse() Twilio API感到困惑。我正在使用Flask处理Web服务器功能。
此外，您是否会偶然知道如何通过redirect路由传递参数，以便我可以在下一条路由中使用该数据并将其保存在数据库中？
非常感谢。我非常感谢我能获得的所有帮助。
