Twilio 基于时间 function

Question

I'm trying to create a Twilio function so that during our business hours it continues the flow in studio, but outside of hours I want it to play the closed message then hang up.

does anyone know how to do this?

There's a ready-to-deploy code sample in the Code Exchange that does exactly what you are looking for. The great thing about this is that you can deploy it without writing any line of code - but obviously you can inspect the deployed code at any time to see what happens:

const moment = require('moment');
const url = require('url');

const GREETINGS = {
  _default: {
    text: 'Hi there! You are calling after my work hours. Please leave a message after the beep',
    language: 'en-US',
    voice: 'Polly.Joey',
  },
  DE: {
    text: 'Hallo! Sie rufen außerhalb meiner Arbeitszeiten an. Bitte hinterlassen Sie mir eine Nachricht nach dem Ton.',
    language: 'de-DE',
    voice: 'Polly.Hans',
  },
};

const DEFAULT_UTC_OFFSET = 0;
const DEFAULT_WORK_WEEK_START = 1; // Monday
const DEFAULT_WORK_WEEK_END = 5; // Friday
const DEFAULT_WORK_HOUR_START = 8; // 8:00, 8AM
const DEFAULT_WORK_HOUR_END = 18; // 18:59, 6:59PM

function getInteger(stringValue, defaultValue) {
  const parsedNumber = parseInt(stringValue, 10);
  if (isNaN(parsedNumber)) {
    return defaultValue;
  }
  return parsedNumber;
}

exports.handler = function (context, event, callback) {
  const phoneNumberToForwardTo = context.MY_PHONE_NUMBER;
  const timezone = getInteger(context.TIMEZONE_OFFSET, DEFAULT_UTC_OFFSET);
  const workWeek = {
    start: getInteger(context.WORK_WEEK_START, DEFAULT_WORK_WEEK_START),
    end: getInteger(context.WORK_WEEK_END, DEFAULT_WORK_WEEK_END),
  };
  const workHour = {
    start: getInteger(context.WORK_HOUR_START, DEFAULT_WORK_HOUR_START),
    end: getInteger(context.WORK_HOUR_END, DEFAULT_WORK_HOUR_END),
  };

  const currentTime = moment().utcOffset(timezone);
  const hour = currentTime.hour();
  const day = currentTime.day();
  const translatedGreeting = GREETINGS[event.FromCountry];
  const hasTranslatedGreeting = typeof translatedGreeting !== 'undefined';
  // between monday and friday
  const isWorkingDay = day <= workWeek.end && day >= workWeek.start;
  // between 8am and 7pm
  const isWorkingHour = hour <= workHour.end && hour >= workHour.start;

  const twiml = new Twilio.twiml.VoiceResponse();

  if (isWorkingDay && isWorkingHour) {
    twiml.dial(phoneNumberToForwardTo);
  } else {
    if (hasTranslatedGreeting) {
      twiml.say(
        {
          language: translatedGreeting.language,
          voice: translatedGreeting.voice,
        },
        translatedGreeting.text
      );
    } else {
      twiml.say(
        {
          language: GREETINGS._default.language,
          voice: GREETINGS._default.voice,
        },
        GREETINGS._default.text
      );
    }
    twiml.record({
      action: url.resolve(context.PATH, 'recording'),
    });
  }
  callback(null, twiml);
}
