使用 axios 从 twilio 运行时获取实时 json 数据 [英] get real-time json data from twilio runtime with axios

问题描述

我正在尝试从 twilio 无服务器功能中获取实时数据.我正在使用稍微编辑的样板函数.我想要的是服务器中的 json 数据和呼叫中的语音响应连续.但以下代码没有将 json 数据发送到服务器.

I am trying to achieve real-time data from twilio server-less function. I am using a boilerplate function edited a little bit.What I want is json data in server and voice response in call consecutively .but the following code is not sending json data to server.

const axios = require('axios');

exports.handler = function (context, event, callback) {
let twiml = new Twilio.twiml.VoiceResponse();
twiml.say('you are welcome ');


 const instance = axios.create({
  baseURL: 'http://fafc4eac4162.ngrok.io/',
  timeout: 3000,

  });

 instance
   .post('/test', {
    id: 1,
    title: 'Twilio'
  })
  .then((response) => {
    console.log(JSON.stringify(response.data));
 
  })
   .catch((error) => {
    console.log(error);
    return callback(error);
   });

  return callback(null, twiml);

  };

它显示以下错误，但如果我不使用语音响应回调 return callback(null, twiml) 而是使用简单的 return callback(null, response.data)，它会成功发送数据；

It shows below error,but it sends data successfully if I do not use the voice response callback return callback(null, twiml) and rather use simple return callback(null, response.data);

推荐答案

return callback(null, twiml); 应该在 .then 块中.>

The return callback(null, twiml); should be in the .then block.

  .then((response) => {
    console.log(JSON.stringify(response.data));
    return callback(null, twiml);
  })

此外，该错误表明已达到 3000 毫秒超时，您的应用程序是否返回 200-OK?

Also, the error indicates the 3000ms timeout is hit, is your application returning a 200-OK?
