在 twilio 中处理呼叫结束 [英] Handle call end in twilio

问题描述

我正在使用 Twilio 和 Node.js 构建一个对话式语音机器人.每当通话结束时，我都需要将收集到的数据(在 Twilio autopilot Memory 对象中收集)发送到数据库.如果用户使用机器人完成整个问答会话，我就可以将数据发送到数据库.但是如果用户在中间挂断电话，函数的执行就会完全停止.为了处理这个问题，我在 Twilio 控制台中使用CALL STATUS CHANGES"在调用端触发一个函数(称为 callEnd.js)执行.但是 callEnd 参数中提供的事件对象不包含 Memory 对象.我该如何处理?

I am building a conversational voice bot with Twilio and Node.js. Whenever a call ends, I need to send collected data(collected in Twilio autopilot Memory object) to a database. If the user completes the entire question-answer session with the bot, I am able to send the data to a DB. But if the user hangs up the call in between, the execution of functions stops completely. To handle this, I am triggering a function(called callEnd.js) execution on call-end using 'CALL STATUS CHANGES' in the Twilio console. But the event object provided in callEnd parameter does not contain the Memory object. How do I handle this?

我的目标是将部分收集/全部收集的数据推送到数据库.

My objective is to push partially collected/full collected data to DB.

如果您的问题分布在多个函数中，并且无论用户通过对话进行多远，您都希望永久存储收集到的数据，那么我建议您在每次收到来自 Autopilot 更新数据库的 webhook 时存储答案以及当时 event.Memory 中的所有内容.

If your questions are distributed over several functions and you want to permanently store the collected data no matter how far through the conversation the user gets, then I recommend that you store the answers each time you receive a webhook from Autopilot updating your database with everything that is in event.Memory at that point.

这样您的数据库就会收集数据，并且无论呼叫到达多远，它都将始终包含用户提供的所有答案.

That way your DB will collect the data and it doesn't matter how far the call gets, it will always have all the answers that the user provided.
