在heroku中部署後，我無法使用node.js獲取我的網頁。我收到下面的錯誤。無法在Heroku上運行node.js應用程序
Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.
我在下面解釋我的日誌文件內容。

我將代碼部署到Heroku中，並在開始運行生成的URL時出現上述錯誤。我在下面解釋我的代碼。
的package.json：
{
"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",
"body-parser": "~1.15.2",
"method-override": "~2.3.7",
"mongojs": "~2.4.0",
"crypto-js": "~3.1.8",
"express-session": "~1.14.2",
"multer":"~1.3.0",
"dotenv" : "~4.0.0"
}
}
server.js：
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);
我已經設置使用dotenv港口和下面的文件中給出。
.ENV：
PORT=8989;
在這裏，我需要運行的應用程序。
你能幫我怎麼設置它嗎？ – satya
