which i didn't understand.I have go through the official docs but what am i missing? I have also added actions_intent_OPTION in his Event

以下是我的代码

const functions = require('firebase-functions');
const {actionssdk} = require('actions-on-google');
const app = actionssdk({debug: true});
var admin = require("firebase-admin");
admin.initializeApp(functions.config().firebase);
var firestore = admin.firestore();

exports.webhook = functions.https.onRequest((request, response) => {
    switch (request.body.result.action) {
           case 'countitem':

            firestore.collection('orders').get()
                .then((querySnapshot) => {

                    var orders = [];
                    querySnapshot.forEach((doc) => { orders.push(doc.data()) });
                    // now orders have something like this [ {...}, {...}, {...} ]

                    response.send({
                        speech: `you have ${orders.length} orders11, would you like to see them? (yes/no)`
                    });
                })
                .catch((err) => {
                    console.log('Error getting documents', err);

                    response.send({
                        speech: "something went wrong when reading from database"
                    })
                })
            conv.ask(new Suggestions('Suggestion Chips'));
            conv.ask(new Suggestions(['suggestion 1', 'suggestion 2']));         

            break;

        default:
            response.send({
                speech: "no action matched in webhook"
            })
    }
});

推荐答案

问题是 conv 未定义。通常，如果您使用的是 Google行动库，转换传递给您的履行功能，其中包含可用于设置答复等的方法。

The issue is that conv isn't defined. Typically, if you're using the actions-on-google library, conv is passed to your fulfillment function and contains methods you can use to set replies and so forth.

看起来您要自己处理一切并手动生成JSON响应。如果是这样，您应该将使用JSON 指南作为Webhook的一部分，并 JSON示例存储库。

It looks like you're handling everything yourself and generating the JSON response manually. If so, you should consult the guide for using JSON as part of your webhook and the repository of JSON examples.
