Question

我正在使用以下内容在Cloud9上启动Node应用程序而不会遇到可怕的错误端口或IP警告，除非我将IP地址指定为process.env.IP，否则我会得到：

app.listen(PORT, process.env.IP || 'localhost', function () {
  console.info(`Server listening on ${this.address().address}:${this.address().port}`);
}).on("error", err => {
  console.error(err);
});

但是，我想知道何时将其部署到Heroku并且process.env.IP未定义，是O.K.在Heroku上IP将默认为localhost

当我尝试在Heroku上运行时，我从console.info获取此信息：

Server listening on 127.0.0.1:23128

但是我在Heroku日志中遇到以下错误：

2018-05-31T04:36:26.982797+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
