我的用例:
我的情况是,我正在制作用于收听播客的机器人用户将拨打twilio号码,机器人会询问你想听什么类型的播客,然后录制10秒
录制结束时,它会说用户在我们找到播客时请等待
我希望在我的webhook中进行录制,这样我就能找出来电者的心情并从我的数据库中找到合适的播客mp3文件并播放给来电者
我面临的问题:
我的所有webhooks中都是空洞的
我的代码:
var express = require("express");
var bodyParser = require("body-parser");
var VoiceResponse = require('twilio').twiml.VoiceResponse;
var app = express();
var port = (process.env.PORT || 4000);
app.use(bodyParser.json())
// helper to append a new "Say" verb with alice voice
function say(text, twimlRef) {
twimlRef.say({ voice: 'alice' }, text);
}
// respond with the current TwiML content
function respond(responseRef, twimlRef) {
responseRef.type('text/xml');
responseRef.send(twimlRef.toString());
}
app.post("/voice", function (request, response, next) {
console.log("request: ", request.body); //body is comming as empty object
var phone = request.body.From;
var input = request.body.RecordingUrl;
var twiml = new VoiceResponse();
console.log("phone, input: ", phone, input);
say('What type of podcast would you like to listen. Press any key to finish.', twiml);
twiml.record({
method: 'POST',
action: '/voice/transcribe',
transcribeCallback: '/voice/transcribe',
maxLength: 10
});
respond(response, twiml);
});
app.post("/voice/transcribe", function (request, response, next) {
console.log("request: ", request.body); //body is comming as empty object
var phone = request.body.From;
var input = request.body.RecordingUrl;
var twiml = new VoiceResponse();
var transcript = request.body.TranscriptionText;
console.log("transcribe text: ", transcript);
//here i will do some magic(Ai) to detect user mood and find an
//appropriate mp3 file from my database and send to twilio
var mp3Url = 'https://api.twilio.com/cowbell.mp3'
say('start playing.', twiml);
twiml.play(mp3Url);
respond(response, twiml);
});
app.listen(port, function () {
console.log('app is running on port', port);
});

Twilio开发者传道者在这里。
您使用的是body-parser
,这很好。但是,您正在使用JSON解析器。 Twilio以application/www-x-form-urlencoded
的格式发出请求,因此您应该更改:
app.use(bodyParser.json())
到
app.use(bodyParser.urlencoded({ extended: false }))
然后,您应该将已解析的主体视为request.body
对象的一部分。
作为额外注释,transcribeCallback
将异步发送到呼叫。因此,响应该请求返回TwiML将不会影响该调用。当你得到转录结果时,你需要modify the call in flight, by redirecting it to some new TwiML。 updating a call with Node.js is below的一个例子:
const accountSid = 'your_account_sid';
const authToken = 'your_auth_token';
const client = require('twilio')(accountSid, authToken);
client.calls('CAe1644a7eed5088b159577c5802d8be38')
.update({
url: 'http://demo.twilio.com/docs/voice.xml',
method: 'POST',
})
.then((call) => console.log(call.to));
