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);
});

答案 0 :(得分:0)
最可能的原因是您没有使用Promise
或async
函数调用,因此在对API的调用完成之前,处理程序未返回任何内容。
要解决此问题,callAPI()
需要返回axios.get()
返回的Promise。同样,调用callAPI()
的Intent Handler也需要返回该Promise(或then()
块中的另一个Promise)。
Dialogflow库需要这样做,因此它知道在向用户返回任何内容之前要等待API调用完成(从而解决Promise)。
对于您而言,这就像将对axios.get()
的呼叫更改为类似的
return axios.get(apiUrl).then((result) => {
// Rest of this call here
