我正在尝试让漫游器回答从API接收到的信息，但无法正常工作。

在firebase控制台日志中，我可以看到api确实以所需的信息进行响应。

下面的所有代码：

'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 statements

exports.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);
});
