node.js - 如何从 Twilio 录音通话中获取录音 ID？

Question

我的 twilio 代码是:

const express = require('express');
const VoiceResponse = require('twilio').twiml.VoiceResponse;

const app = express();
const PORT = process.env.PORT || 3000;
app.get('/health', (req, res) => {
  res.send('ok')
})

// Returns TwiML which prompts the caller to record a message
app.post('/record', (request, response) => {
  // Use the Twilio Node.js SDK to build an XML response
  const twiml = new VoiceResponse();
  twiml.say("Hi!");

  // Use <Record> to record the caller's message
  twiml.record();
  console.log(twiml.toString())

  response.send(twiml.toString());
});

// Create an HTTP server and listen for requests on port 3000
app.listen(PORT);

但我想知道录制 ID，以便我可以通过编程方式访问原始文件。我该怎么做？

Answer 1

要获取录制 ID (RecordingSid)，您需要告诉 Twilio 一个 action URL，如下所示:

twiml.record({
    action: '/finished'
});

您可以在此处阅读更多信息:( https://www.twilio.com/docs/voice/twiml/record#attributes )。另外，请阅读 recordingStatusCallback URL 属性，也许这也是您需要的。

然后，您需要解析 Twilio 将向您的应用程序发出的第二个请求的正文。

您可以在这里阅读更多相关信息:( https://www.twilio.com/blog/2016/07/how-to-receive-a-post-request-in-node-js.html )。

为此，您可以使用 body-parser，您可以通过 npm install body-parser 获得它。

录制 ID 将成为 body.RecordingSid 下参数的一部分。

无论如何，这里是对您的代码的粗略修改，以开始:

// npm install express body-parser
const express = require('express');
const bodyParser = require('body-parser');

const VoiceResponse = require('twilio').twiml.VoiceResponse;

const app = express();

// Tell express to use the body-parser middleware and to not parse extended bodies
app.use(bodyParser.urlencoded({
    extended: false
}))

const PORT = process.env.PORT || 3000;
app.get('/health', (req, res) => {
    res.send('ok')
})

// Returns TwiML which prompts the caller to record a message
app.post('/record', (request, response) => {
    // Use the Twilio Node.js SDK to build an XML response
    const twiml = new VoiceResponse();
    twiml.say("Hi!");

    // Use <Record> to record the caller's message
    twiml.record({
        action: '/finished'
    });
    console.log(twiml.toString())

    response.send(twiml.toString());
});

app.post('/finished', function (req, res) {
    const body = req.body;
    res.set('Content-Type', 'text/plain');
    res.send(``);
    console.log(body);
    console.log(body.RecordingSid);
});

// Create an HTTP server and listen for requests on port 3000
app.listen(3000, function () {
    console.log('Example app listening on port 3000!')
})

我希望这会有所帮助。
