我正在嘗試讓機器人回答從 API 收到的信息，但無法正常工作。在 firebase 控制臺日志中，我可以看到 api 確實響應(yīng)了我需要的信息。下面的所有代碼：'use strict';const axios = require('axios');const functions = require('firebase-functions');const {WebhookClient} = require('dialogflow-fulfillment');const {Card, Suggestion} = require('dialogflow-fulfillment');process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statementsexports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {  const agent = new WebhookClient({ request, response });  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));  function welcome(agent) {    agent.add(`Welcome to my agent!`);  }  function fallback(agent) {    agent.add(`I didn't understand`);    agent.add(`I'm sorry, can you try again?`);  }  function callAPI(agent){    const food = agent.parameters.Food;    const subject = agent.parameters.Subject;    const number = agent.parameters.number;    const question = subject + " "+number +" "+food;    const questionReady = question.replace(/ /g, '+');    const apiKey = "key";    const baseUrl = "https://api.spoonacular.com/recipes/quickAnswer?q=";    const apiUrl =  baseUrl + questionReady + "&apiKey=" + apiKey;    axios.get(apiUrl).then((result) => {        console.log(result);           console.log(result.data);           console.log(result.data.answer);        agent.add(result);        agent.add(result.data);        agent.add(result.data.answer);    });  }  let intentMap = new Map();  intentMap.set('Default Welcome Intent', welcome);  intentMap.set('Default Fallback Intent', fallback);  intentMap.set('food', callAPI);  agent.handleRequest(intentMap);});
