node.js - Express.js REST API 无法在 Heroku 上运行

Question

我已经编写了一个基本的node.js应用程序，它在本地使用以下命令运行:node app.js，但不在heroku中，这是我的package.json

{
  "name": "express-rest-youness",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "express": "^4.16.2",
    "express-rest": "^1.0.4"
  }
}

和我的 app.js

 var express = require('express'),
    expressRest = require('express-rest');

 var app = express();
var rest = expressRest(app);

var records = [
    {value: 'Apple'},
    {value: 'Banana'}
];

rest.get('/api/food', function(req, rest) {
    rest.ok(records);
});

rest.get('/api/food/:id', function(req, rest) {
    var record = records[req.params.id];
    if (record) rest.ok(record);
    else rest.notFound();
});

rest.put('/api/food/:id', function(req, rest) {
    records[req.params.id] = req.body;
    return rest.accepted('/api/food/' + encodeURI(req.params.id));
});

rest.post('/api/food', function(req, rest) {
    records.push(req.body);
    rest.created('/api/food/' + (records.length - 1));
});

rest.delete('/api/food/:id', function(req, rest) {
    delete records[req.params.id];
    rest.gone();
})


app.listen(8080);

当尝试访问heroku应用程序时，我得到:

应用程序错误 应用程序发生错误，无法提供您的页面。如果您是应用程序所有者，请检查您的日志以了解详细信息。

谢谢:)
