如何从该意图本身的后续跟踪中递归地触发 DialogFlow 中的意图？

Question

I'm currently working on a dialogflow chat bot and I'm in a situation where I need to recursively trigger an intent. The scenario is like this:

I created a bot for creating flight request from the conversation of user. For a multicity flight request, I need to add multiple flight sectors. After adding each sectors, the user will be prompted whether to add another sector or not. If user says yes, then the bot need to trigger the multicity flight request intent again. How can I achieve this?

Intents are "triggered" by a user phrase or event. Trying to trigger them "recursively" probably isn't exactly what you want. Remember - Intents represent what the user says and not how you handle or reply to what they say.

What it sounds like you're trying to do is:

• Once a user has given a response, prompt them if they would like to add another sector.
• If they reply yes, prompt them for that information. (If they reply no, go handle that.)
• Keep repeating this until they reply no.

Keep in mind that this loop is driven by what the user says .

Based on this, the best approach is:

• The Intent that handles the user giving information should have an Input Context, so it will only be triggered when that Context has a lifespan greater than 0.
• When the user responds that they have more information, set that Context to a lifespan greater than 0 with your webhook and prompt them to give you the information.
• If the user responds they are done, set the Context lifespan to 0 so the Intent won't be triggered.
