HTTP and HTTPS same time (Express.Io) - node.js

Question

I'm successfully listenin port 443 and can access server over https, but I can't access it with http.
var fs = require('fs')
options = {
ca : fs.readFileSync('./ssl/site.com.pem'),
key: fs.readFileSync('./ssl/site.com.key'),
cert: fs.readFileSync('./ssl/site_com.crt')
}
var app = require('express.io')
app.https(options).io()
....
app.listen(443);
I've tried using http and https modules:
app.http().io();
http.createServer(app).listen(80);
https.createServer(options, app).listen(443);
But this time socket.io is giving 404 in browser. How can I solve this? I need to use Express.Io's socket connection because application is based on it.

Answer 1

You should redirect http to https
var express = require('express'),
app = express(),
httpapp = express();
//........................
var credentials = {key: privateKey, cert: certificate, ca: ca};
var httpsServer = https.createServer(credentials, app);
var httpServer = http.createServer(httpapp);
httpsServer.listen(443);
httpServer.listen(80);
httpapp.route('*').get(function(req,res){
res.redirect('https://yourdomain.com'+req.url)
});

Had the same problem a few days ago, and this GitHub issue helped:

Your code is on the right way, it just need some changes. The code below is a slightly modified version of the snippet you provided.
var fs = require('fs'),
express = require('express.io');
options = {
ca : fs.readFileSync('./ssl/site.com.pem'),
key: fs.readFileSync('./ssl/site.com.key'),
cert: fs.readFileSync('./ssl/site_com.crt')
};
var app = express();
app.https(options).io();
var httpServer = require('http').createServer(app);
// ...
app.listen(443);
express.io.listen(httpServer);
httpServer.listen(80, function() { }, function() { });
