对话框流从列表中选择 [英] Dialogflow selecting from list

问题描述

我正在创建一个聊天机器人，模仿通话中的ivr。因此，例如，当用户打个招呼（欢迎意图）时，我发送一条消息，例如，请从下面选择一个选项。

I am creating a chat bot which mimic the ivr in call. So for example when user say hi (welcome intent) I send a message like please select an option from below.

 1, 2, 3, 4, 5 (every option gives user a unique information)

然后我创建欢迎意图的后续意图，如默认欢迎意图select.number

then I create a follow up intent of welcome intent as Default welcome intent select.number

在这种情况下，当用户键入2时，我会给他另一组选项。
从下面选择选项

in this situation when user type 2 I give him another set of options. choose the option from below

a, b, c, d, e, f

现在，例如用户类型 a 我需要在dialogflow上创建什么意图进一步处理。

Now for e.g user type a what intent I need to create on dialogflow to process further.

我正在使用我的python脚本拦截用户答复

I am intercepting the user reply using my python script

并从python脚本调用dialogflow。

and calling dialogflow from python script.

 reply, intent, parameter = fetch_reply(x, session_id)

 def fetch_reply(query, session_id):
    response = detect_intent_from_text(query, session_id)

    inetnt = response.intent.display_name

    # print(inetnt)

    # print('-----')
    value = 0.0
    try:
        if response.parameters['number']:
            value = response.parameters['number'][0]

    except ValueError:
        print('no value found')

    return response.fulfillment_text, inetnt, value

在这里，如果用户选择<$ c，我可以简单地使用 if $ c> a ，然后向他发送答复，但是dialogflow是否提供了我可以用来为用户输入提供答​​案的任何内容。

From here I can simply use if else if user select a and then send him reply but is there anything that dialogflow provide which can I use to give answers to user inputs.

还有一个供用户选择的选项，例如按0返回主菜单。
如何处理？

Also there is a option for user like press 0 to go back to main menu. How can I handle it?

如果您希望我提供任何其他信息，请告诉我。

If you want me to provide any other info please let me know.

推荐答案

一种可能的方法是为每个可能的选项{1、2、3 ..a，b，c}创建Intent，并在每次回复后将它们作为建议包括在内。例如，当用户说嗨时，您可以选择1，2，3 ...作为 Hello来回答。当用户选择1时，a，b，c ...会显示为建议。以下代码可以提供帮助：

One possible way is to create Intent for each possible options {1, 2, 3 ..a, b, c} and include them in as Suggestion after each reply. For example, when the user says "Hi" you can respond as "Hello" with 1, 2, 3 ... as selectable suggestions. And when user selects 1 then a, b, c... appear as Suggestions. Here's some code that can help:

.
.
.
const {Card, Suggestion} = require('dialogflow-fulfillment');
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
    const agent = new WebhookClient({request, response });
    function welcome(agent){
    agent.add(`Hello!`);
    agent.add(new Suggestion(`1`));
    agent.add(new Suggestion(`2`));
    agent.add(new Suggestion(`3`));
    }
