ReferenceError：在Google动作中未定义转化

Question

我想在我的Dialog流程中实现“建议”芯片（将在Google助手中使用）。但是我收到此错误

  

“ ReferenceError：未定义conv”

我不了解。我已经查阅了官方文档，但是我想念的是什么？我还在他的活动

中添加了actions_intent_OPTION

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"
            })
    }
});

问题是conv未定义。通常，如果您使用的是actions-on-google library，则conv会传递给您的履行功能，其中包含可用于设置回复等的方法。

您似乎要自己处理一切并手动生成JSON响应。如果是这样，则应将guide for using JSON作为Webhook的一部分，并将repository of JSON examples作为Webhook的一部分。
