node.js - 使用 Heroku 无法在 Node js 中获取/错误

Question

我正在开发 Node js 后端，它使用 telerivet webhook API 从 Android 应用程序接收用户短信。每次我运行应用程序 atheroku 时，它都会给我无法 GET/错误，我的 index.js 代码是

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

var WEBHOOK_SECRET = "62DZWMCCFFHTTQ44CG3WUQ94CTT7GAAN";

app.post('/telerivet/webhook', 
bodyParser.urlencoded({ extended: true }),
function(req, res) {
  var secret = req.body.secret;
  if (secret !== WEBHOOK_SECRET) {
      res.status(403).end();
      return;
  }

  if (req.body.event == 'incoming_message') {

    var content = req.body.content;
    var from_number = req.body.from_number;
    var phone_id = req.body.phone_id;

    // do something with the message, e.g. send an autoreply
    res.json({
      messages: [
        { content: "Thanks for your message!,Our Backend Is Still in Alpha Stage,Hang Tight" }
      ]
    });

  }  

  res.status(200).end();
 }
 );

app.listen(process.env.PORT || 5000);

请帮忙，我哪里做错了当我在浏览器上运行应用程序时，它给了我无法获取/错误，并且在使用应用程序测试时也不回复短信

我找到了出路，这是我的新代码:

  var express = require('express');
  var app = express();

 app.set('port', (process.env.PORT || 5000));
 app.use(express.static(__dirname + '/public'));

 app.get('/', function(request, response) {
 response.send('Hello World!');
 });

 var bodyParser = require('body-parser');

 var WEBHOOK_SECRET = "62DZWMCCFFHTTQ44CG3WUQ94CTT7GAAN";

 app.post('/telerivet/webhook', bodyParser.urlencoded({ extended:    true     }),function(req, res) {
    var secret = req.body.secret;
    if (secret !== WEBHOOK_SECRET) {
      res.status(403).end();
      return;
    }

    if (req.body.event == 'incoming_message') {

      var content = req.body.content;
      var from_number = req.body.from_number;
      var phone_id = req.body.phone_id;

    // do something with the message, e.g. send an autoreply
       res.json({
        messages: [
        { content: "Thanks for your message!,Stay Tuned for Awesome " }
      ]
    });

     }  

     res.status(200).end();
     }
      );

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