在 Dialogflow 对话中积累响应参数，然后通过组合所有参数进行 web-hook 请求

Question

我正在使用 Dialogflow 制作一个基本的旅行聊天机器人。假设我在第一个响应中获得登机地点，在第二个响应中获得着陆位置，在第三个响应中获得旅行日期。现在我想累积所有三个参数并对某个航班 API 进行自定义 webhook 响应。执行此操作的正确方法是什么？目前我所做的是将每个上下文的生命周期增加到 15（假设最大对话长度），然后从 json 的 outputContexts 参数中提取参数。 json 回复已附在下方。

另一个用例可以是在 2 个后续对话中获取城市和日期，然后进行组合网络挂钩响应以获取天气预报。

由于我是 dialogflow 的新手，所以我想不出更好的解决方案。有人可以告诉 correct/easier 方法吗？

Answer 1

由于您是 Dialogflow 的新手，我想向您推荐 Understand fulfillment by integrating Dialogflow with Calendar codelab，您将能够在其中看到设置 fulfillment 的正确过程。

你的解决方案似乎是正确的，另外你可以检查这个tutorial这与你的情况相似。
