Question

在heroku中部署后，我无法使用node.js获取我的网页。我收到以下错误。

我正在解释下面的日志文件内容。

{
  "name": "FGDP",
  "description": "Our sample Node to Heroku app",
  "main": "server.js",
  "scripts": {
    "start": "node server.js"
  },
  "dependencies": {
    "express": "~4.14.0",
    "morgan": "~1.7.0",

    "multer":"~1.3.0",
    "dotenv" : "~4.0.0"
  }
}

我将代码部署到Heroku中，当开始运行生成的URL时，我收到上述错误。我在下面解释我的代码。

的package.json：

var express=require('express');
var morgan = require('morgan');
var http=require('http');
var bodyParser= require('body-parser');
var methodOverride = require('method-override');
var mongo = require('mongojs');
var session = require('express-session');
var multer  = require('multer')
var app=module.exports=express();
var server=http.Server(app);
const dotenv = require('dotenv');
dotenv.load();
var port=process.env.PORT;
var admin=require('./route/route.js');
app.use(express.static(__dirname + '/public'));     // set the static files location /public/img will be /img for users
app.use(morgan('dev'));                     // log every request to the console
app.use(bodyParser.urlencoded({ extended: false }))    // parse application/x-www-form-urlencoded
app.use(bodyParser.json())    // parse application/json
app.use(methodOverride());                  // simulate DELETE and PUT
app.use(session({secret: 'FGDPlexel',resave: true,saveUninitialized: true}));
app.get('/',function(req,res){
    res.sendFile(__dirname + '/index.html');
})
var storage =multer.diskStorage({
  destination: function (req, file, callback) {
    callback(null, './uploads');
  },
  filename: function (req, file, callback) {
    callback(null, file.fieldname + '-' + Date.now());
  }
});
app.post('/login',admin.userlogin);
app.get('/getSessionValue',admin.getSession);
server.listen(port);
console.log("Server is running on the port"+port);

server.js：

dotenv

我已使用PORT=8989;设置端口，文件如下所示。

.ENV：

{{1}}

我需要运行该应用程序。

Answer 1

不要使用dotenv。您可以从CLI或heroku仪表板中的设置选项卡设置环境变量。在此处阅读更多相关信息：https://devcenter.heroku.com/articles/config-vars#setting-up-config-vars-for-a-deployed-application

Answer 2

根据this issue，dotenv不会在生产环境中使用Heroku。使用Heroku仪表板设置环境变量。

无法在Heroku上运行node.js应用程序
