letsencrypt-express con Socket.IO

Question

Non capisco, come configurare LEX con socket.io. Ecco quello che ho adesso:

server.js

var express = require('express'); 
var app = express(); 
var bodyParser = require('body-parser'); 

app.use(bodyParser.urlencoded({limit: '50mb', extended: true })); 
app.use(bodyParser.json({limit: '50mb'})); 

var port = 80; 
if(process.argv[2] == 'dev') port = 3001; 

var router = express.Router(); 

app.use(function (req, res, next) { 
    res.setHeader('Access-Control-Allow-Origin', '*'); 
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE'); 
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type, userId'); 
    next(); 
}); 

var api = require('./api'); 
api(app, port) 

app.use(express.static(__dirname + "/../dist")); 
app.get('/', function(req, res) { 
    res.render('index.html'); 
}); 
console.log('Magic happens on port ' + port); 

api.js

var API = function(app, port){ 
    var pg = require('pg'); 
    var lex = require('letsencrypt-express').testing(); 

    var connectedUsers = {}; 

    var config ={ 
    user: "postgres", 
    password: "password", 
    database: "production", 
    port: 5432, 
    host: "serverIpAddress", 
    ssl: false 
    }; 

    pg.connect(config, function(err, client, done) { 

    if (err) { 
     return console.error('error fetching client from pool', err); 
    } 
    // var server = require('http').Server(app); 
    var server = lex.create({ 
     configDir: './letsencrypt.config', 
     onRequest: app, 
     letsencrypt: null, 
    }); 


    var io = require('socket.io')(server); 

    server.listen(port); 

    io.on('connection', function (socket) { 
     console.log('new connection') 

    }); 
    }); 

} 

module.exports = API 

dare un'occhiata alla linea commentata in api.js: tutto funziona bene quando uso questo, invece di:

var server = lex.create({ 
     configDir: './letsencrypt.config', 
     onRequest: app, 
     letsencrypt: null, 
    }); 

Con LEX sto ricevendo questo errore cercando di eseguire il server:

012.351.

Immagino, ho un errore molto semplice nel mio codice, perché non stavo configurando Socket.io con SSL prima.

Grazie

Prova questo codice. Funzionerà solo con la versione più recente di letsencrypt-express.

app.js

var express = require('express'); 
var app = express(); 
var socketIO = require('socket.io'); 
var LEX = require('letsencrypt-express').testing(); 
var https = require('http2'); 

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

var lex = LEX.create({ 
    configDir: '/etc/letsencrypt' 
, letsencrypt: null 
, approveRegistration: function (hostname, cb) { 
    cb(null, { 
     domains: ['example.com'] 
    , email: 'info@example.com' 
    , agreeTos: true 
    }); 
    } 
}); 

var server = https.createServer(lex.httpsOptions, LEX.createAcmeResponder(lex, app)); 
server.listen(443); 

var io = socketIO.listen(server); 
io.on('connection', function (socket) { 
    socket.emit('news', { hello: 'world' }); 
    socket.on('my other event', function (data) { 
    console.log(data); 
    }); 
}); 

index.html

<script src="https://cdn.socket.io/socket.io-1.4.5.js"></script> 
<script> 
    var socket = io.connect('https://example.com'); 
    socket.on('news', function (data) { 
    console.log(data); 
    socket.emit('my other event', { my: 'data' }); 
    }); 
</script>
