Nodejs - Socketio 不能与 https 服务器一起使用，可能是什么原因？

Question

我尝试使用 http 服务器进行调试，并且 socket.io 工作，但是当我尝试使用 https 时 socket.io 停止工作

// create server for http and https
//var httpserver = http.createServer(app).listen('3000', '127.0.0.1');
var https_server = https.createServer(options, app).listen('4000', '127.0.0.1');
// let the backend listens to this server
UserServer.listen(https_server);
//UserServer.listen(httpserver);


exports.listen = function(server){

    io = socketio.listen(server);
    io.sockets.on('connection', function(socket){
        console.log("Socket is connected, sweet ");
    });
} 

当

var httpserver = http.createServer(app).listen('3000', '127.0.0.1');
UserServer.listen(httpserver);

打印出来

Socket is connected, sweet "

当

var https_server = https.createServer(options, app).listen('4000', '127.0.0.1');
UserServer.listen(https_server);

没有输出

这是我的 https 设置

var express = require('express'),               
    https = require('https'),
        fs = require('fs'); 



var options = {
  key: fs.readFileSync('./key.pem', 'utf8'),
  cert: fs.readFileSync('./cert.pem', 'utf8')
};

我能够显示 https 页面，所以我猜 https 设置不是问题

任何建议将不胜感激，谢谢

首先，你需要运行Node.js Server with SSL。

Server.js

var fs = require('fs');    
var options = {
    key: fs.readFileSync('ssl/private/domain.com.key'),
    cert: fs.readFileSync('ssl/certs/domain.com.crt'),
    ca: fs.readFileSync('ssl/certs/domain.com.cabundle')
};
// You can do this easily if you are on windows 
// var options = { pfx: fs.readFileSync('/home/mydir/secure.pfx'); };
var app = require('https').createServer(options, handler),
    io = require('socket.io').listen(app);    

//Recommended Production settings
io.enable('browser client minification');  // send minified client
io.enable('browser client etag');          // apply etag caching logic based on version number
io.enable('browser client gzip');          // gzip the file
io.set('log level', 1);                    // reduce logging
io.set('flash policy port', 3300); //==>  override Flash Policy Port  
io.set('transports', [                     // enable all transports (optional if you want flashsocket)
    'websocket'
  , 'flashsocket'
  , 'htmlfile'
  , 'xhr-polling'
  , 'jsonp-polling'
]);
function handler(req, res) {
    res.writeHead(200);
    res.end("welcome sir!");
};    
io.sockets.on('connection', function (socket) {
    socket.on('message', function (data) {
        socket.broadcast.emit('message', data);
    });
});    
app.listen(3300);

Client.js

   //socketAddress is server uri  ex. https://www.domain.com:3300
   var socket = io.connect(socketAddress, {'flash policy port':3300} );
   socket.on('connect', function (data) {
      //.... 
   });
   socket.on('message', function (data) {
      //.... 
   });
