我想在用户连接到websocket之前读取会话/cookie数据

我的websocket是使用Socket.io和express framework实现的

这就是我所做的

const env = require('./config');
const sess = require('./sessions');
const app = require('express')();
const https = require('https');
const fs = require('fs');
const session = require('express-session');
const RedisStore = require("connect-redis")(session);
const cookieParser = require('cookie-parser')
const connect = require('connect');
const server = https.createServer(
    {
        key: fs.readFileSync('certs/key.pem'),
        cert: fs.readFileSync('certs/cert.pem')
    }, function (req, res){
        res.setHeader('Access-Control-Allow-Origin', '*');
        res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type');
    }
).listen(env.socket.port, env.socket.host, function () {
    console.log('\033[2J');
    console.log('Websocket is running at https://%s:%s', server.address().address, server.address().port);
});

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

const sessionMiddleware = session({
    store: new RedisStore({
        host: env.redis.host,
        port: env.redis.port
    }),
    secret: env.session.secret,
    name: env.session.name,
    rolling: false,
    resave: true,
    saveUninitialized: true,
});

var clients = {};

io.use(function(socket, next) {
    sessionMiddleware(socket.request, socket.request.res, next);
});
var myCookieParser = cookieParser(env.session.secret);

app.use( myCookieParser ) ;
app.use( sessionMiddleware );

io.set('authorization', function (handshakeData, accept) {

    onsole.log(handshakeData.headers.cookie);

    if (handshakeData.headers.cookie) {

        var cookies = myCookieParser(handshakeData.headers.cookie);
        console.log(cookies);
        return ;

        handshakeData.sessionID = connect.utils.parseSignedCookie(cookies['connect.sid'], env.session.secret);

    if (cookies['connect.sid'] == handshakeData.sessionID) {
        return accept('Cookie is invalid.', false);
    }

  } else {
        return accept('No cookie transmitted.', false);
  } 

  accept(null, true);
});


io.on('connection', function (socket) {

    var origin = socket.request.headers.origin || '';
    var myIP = socket.request.socket.remoteAddress || '';
    var socketId = socket.id;
    var session_id = '';
    var authorized = false;
    var req = socket.request;

    //console.log(socket.request);
    console.log('SessionID: ' + socket.request.sessionID)

    if (!originIsAllowed(origin)) {
        // Make sure we only accept requests from an allowed origin
        socket.destroy();
        console.log((new Date()) + ' Connection from origin ' + origin + ' rejected.');
        return false;
    }

    if(req.sessionID){
        session_id = req.sessionID;
    }

    if(req.session.authorized){
        authorized = req.session.authorized;
    }

    socket.on('chat', function(msg){
        //only autherized users can chat
        if( session.authorized ){
            console.log('Chat Message: ' + msg);
            socket.emit('chat', { message: msg });
        }

    });


    socket.on('disconnect', function(msg){
        console.log('Closing sessionID: ' + session_id);
        var userCons = clients[session_id] || [];

        var index = userCons.indexOf(socketId);

        if(index > -1){
            userCons.splice(index, 1);
            console.log('Removed Disconnect Message: ' + msg);
        } else {
            console.log('Disconnect Message: ' + msg);
        }

    }); 

    socket.on('error', function(msg){
        console.log('Error Message: ' + msg);
    }); 

});


function originIsAllowed(origin) {
    // put logic here to detect whether the specified origin is allowed.
        var allowed = env.session.allowedOrigins || []

        if(allowed.indexOf(origin) >= 0){
            return true;
        }

    return false;
}

当我启动服务器时，我得到了所有的错误

如何正确解析cookies

已编辑

把问题改成这样之后

var cookies = myCookieParser(handshakeData);

我得到这个错误

错误引用了完全不同的行

var cookies=req.headers.cookie，我想你需要换一个地方看。@YuriZarubin在注释那行并在它之后返回时，我没有得到那个错误哦，对了，nvm。是的，它抱怨的原因是它期望的是一个请求
对象，而不是实际的cookie。所以它试图解析实际的cookie。@YuriZarubin当我这样做时，mycokieparser（handshakeData.headers）
我得到了一个正确的错误，因为那也不是请求对象。怎么样mycokieparser（握手数据）
