无法在firebase云函数的助手中获取用户的响应

我需要一个帮助，我在dialogflow firebase函数中没有得到用户的响应。请在index.js中找到编码 在测试内容中，我想获得用户的响应用户的答案，我尝试了app.intent'Test intent'，conv，input，并在ask中使用了${input}。现在我尝试了app.intent'testintent'，conv，params，我没有得到用户的响应。请让我知道，如何获得用户的响应

import * as functions from 'firebase-functions';
import * as gApp from 'actions-on-google';
import { myService } from './services/myService';
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
import admin from 'firebase-admin';
const app = gApp.dialogflow({debug: true});

process.env.DEBUG = 'dialogflow:debug'; 

//exports.dialogflowSample = functions.https.onRequest((request, response) => 
//{


  app.intent('Default Welcome Intent',(conv) => {
    conv.ask(`Welcome to my dialogFlow agent! <say-as >${input}</say-as>.</speak>`);
    //conv.data.question = 'question1';

  });


app.intent('Test Intent',(conv,params) => {
    let qNo:string  =   conv.data.question;
    conv.ask('<speak>Testing the application'
    +`<say-as >`+conv.params.pain+`</say-as>.</speak>`);
    conv.ask('<speak>Testing the application'+`<say-as >`+qNo+`</say-as>.</speak>`);
    });

  exports.dialogflowSample = functions.https.onRequest(app);
//});

如果您想准确返回用户所说的内容，可以执行以下操作：

app.intent('Test Intent',conv => {
    let userRawInput  =   conv.input.raw;
    conv.ask("You said exactly: "+userRawInput);
    });

如果我使用google home进行测试，我会在conv.input.raw中得到相同的值吗，，你有没有参考conv中所有对象引用的指南，谷歌上的操作等等。我所做的是打印conv对象并检查其字段，然后找到我感兴趣的内容并使用它
