letsencrypt-express与Socket.IO

我不明白，我如何configurationLEXO与socket.io。 这里我现在有什么：

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 

看看在api.js注释掉了一切：当我使用这个而不是：

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

与LEX我收到此错误尝试运行服务器：

 [LEX] testing mode turned on [LEX] default server: https://acme-staging.api.letsencrypt.org/directory ################################################### # # # Open up a browser and visit this server # # at its domain name. # # # # ENJOY! # # # ################################################### Note: testing certs will be installed because .testing() was called. remove .testing() to get live certs.

我想，我的代码中有一个非常简单的错误，因为我之前没有使用SSLconfigurationSocket.io。

谢谢

试试这个代码。 它只能使用最新版本的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: '[e-mail]' , 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); }); }); 

的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>
