I integrated the cookie-parser module into my express app. When a user requests the root page, I use res.cookie(name, value) to set a random number on the cookie, which is working correctly (I verified this in my browser console). However, when I attempt to log req.cookie, it always returns undefined.
Below is the code snippet:
routes.js
var express = require('express')
var router = express.Router()
var movieTrailer = require('movie-trailer');
var Promise = require('bluebird');
var logs = require('log-switch');
var fs = require('fs');
//var cookieParser = require('cookie-parser');
//Setting up x-ray for scraping
var Xray = require('x-ray');
var x = Xray();
var debug = false;
router.get('/', (req, res) => {
console.log('Page requested!');
console.log('Cookies: ', req.headers.cookies); // This line returns undefined for some reason
var scrapeMovies = function(){
return new Promise((resolve, reject) =>{
fs.readFile('moviesRT.json', (err,data) =>{
var movies = JSON.parse(data);
resolve(movies);
});
});
};
scrapeMovies().then(
movies => {
var randomInt = Math.floor(Math.random() * movies.length);
res.cookie('randomInt', randomInt);
var randomMovie = movies[randomInt];
movieTrailer(randomMovie.title, (err, url) =>{
console.log('Requesting trailer: ', randomMovie.title);
if(err) throw err;
var embedUrl = url.replace('watch?v=','embed/');
console.log('Video ID: ', url.slice(32,url.length));
randomMovie.trailerURL = embedUrl;
res.render('main',randomMovie,
(err, html) =>
{
if(err) throw err;
console.log('Rendering...');
res.send(html);
console.log("Done!");
});
});
});
});
module.exports = router;
app.js
const express = require('express');
//Define app and settings
const app = express();
const exphbs = require('express-handlebars');
var cookieParser = require('cookie-parser');
const port = 3000;
var routes = require('./routes');
var debug = true;
app.use('/', routes);
app.use(express.static('public'));
app.use(cookieParser());
//app.use(cookieParser());
//View engine
app.engine('handlebars', exphbs({defaultLayout: 'main'}));
app.set('view engine', 'handlebars');
app.listen(port, function () {
console.log(`Server Starts on ${port}`);
if(!debug) logs.disable();
});
