Question

我的Node.js应用程序设置为响应以付费Twilio号码收到的短信。我用ngrok测试了它，一切正常。然而，一旦我将应用程序部署到Heroku，我就开始在Twilio控制台中看到11200 HTTP检索失败错误。

Heroku中是否需要设置配置设置？

// Twilio Credentials
const accountSid = 'xxx';
const authToken = 'xxx';
const client = require('twilio')(accountSid, authToken);
const MessagingResponse = require('twilio').twiml.MessagingResponse;

var express = require('express');
var app = express();   
var bodyparser = require('body-parser');

app.use(bodyparser.urlencoded({extended: true}));

app.set('port', (process.env.PORT || 3000));

app.use('/', function(request, response){
response.send();
});

app.post('/sms', function(req, res) {

const twiml = new MessagingResponse();

twiml.message('Hi, this is Culpability. Your incident has been logged. Your 
unique id # XXXX');

res.writeHead(200, {'Content-Type': 'text/xml'});
res.end(twiml.toString());

});

app.listen(app.get('port'), function() {
// console.log('Node app is running on port', app.get('port'));
});

Twilio开发者传道者在这里。

我认为问题主要在于您用于发送响应的方法。目前，/sms路线的最后一行是res.end(twiml.toString()); Response#end is used "to quickly end the response without any data."

我认为你对res.writeHead()的使用现在也可能已经过时了。

我会将您的/sms路线更改为以下内容：

app.post('/sms', function(req, res) {
  const twiml = new MessagingResponse();
  twiml.message('Hi, this is Culpability. Your incident has been logged. Your unique id # XXXX');
  res.set('Content-Type', 'text/xml');
  res.status(200).send(twiml.toString());
});

然后尝试重新部署到Heroku，看看会发生什么。
