Question

我以前曾研究过类似的问题，但没有一个解决方案为我解决，这就是为什么我要问这个问题。我只是试图将我的node.js应用程序部署到heroku，但我不断收到应用程序错误。

以下是我的日志的一部分：

以下是我的package.json文件：

{
  "name": "pg_backend",
  "version": "1.0.0",
  "description": "back end application for the project gorilla site",
  "main": "index.js",
  "scripts": {
    "start": "node server.js"
  },
  "engines": {
    "node": "8.10.0",
    "npm": "5.6.0"
    },
  "author": "Christopher Salay",
  "license": "ISC",
  "dependencies": {
    "express": "^4.16.3",
    "nodemailer": "^4.6.8",
    "socket.io": "^2.1.1",
    "vimeo": "^2.1.0"
  }
}

这是我的Procfile：

web: node server.js

以下是我的server.js

let express = require('express'), app = express(), path = require('path'),
socket = require('socket.io'), emailModule = require('./email.js'), 
formValidationModule = require('./formValidation.js'), vimeoModule = require('./vimeo.js'),
port = process.env.PORT || 5000;

app.get('/', function(req, res) {
    res.sendFile(path.join(__dirname + '/index.html'));
});

let server = app.listen(port,'0.0.0.0',function(){
    console.log('listening to requests...');
    vimeoModule.search()
});

let io = socket(server);


io.on('connection', (socket)=>{
    console.log('made a connection!');

    socket.on('email', (data)=>{
        if(formValidationModule.checkEmptyContact(data.client, data.email, data.name, 
            data.title, data.message)){
                socket.emit('invalidData');
            }
            else {
            /**
                 * * Here you need to set your email options which includes the clients email, destination email,
                 * subject and the text (the email content).
                 */
                emailModule.setMailOptions(data.email,/*'Info@project-gorilla.co.uk'*/'salay777@hotmail.co.uk'
                , data.client + ' ' + '(' +
                data.name + ')' + ' ' + data.title, data.message).then((mailOpts)=>{
                    emailModule.send(mailOpts)

                });
                console.log('email has been sent!');
            }
    });
});

链接到heroku应用程序：

https://pg-gorilla-backend.herokuapp.com/

并且我使用以下命令部署到heroku：

git push heroku master

您需要在heroku上配置端口，因为在部署到heroku时无法将静态端口传递给应用程序，Heroku内置了将指定端口绑定到部署在其环境中的应用程序的方法。您需要使用env var来为应用程序分配端口。在heroku应用程序中，您可以通过“设置”>“显示配置变量”>“在其中添加端口3000”来执行此操作，然后内置的heroku方法将为应用程序分配指定的端口号。
