简单的NodeJS部署到Heroku
我试图部署一个痛苦简单的NodeJS应用程序到Heroku。
var http = require('http'); var server = http.createServer(function(req, res) { res.writeHead(200); res.end('Hello World'); }).listen(3000); 我已经在本地进行了testing，并运行以下命令。
heroku login heroku create marktyers git push heroku master heroku ps:scale web=1
该应用程序似乎部署，但是当我查看的URL我得到一个应用程序错误。
https://marktyers.herokuapp.com
这里是英雄日志。
节点server.js

Heroku提供的示例应用程序使用Express包，因此没有什么用处，可以帮助我理解问题。
这是推送时的消息：

问题是使用固定的端口号。 如果我将端口设置为process.env.PORT则应用程序正确部署。
