我正在尝试从套接字访问会话，但似乎无法建立连接。没有失败，授权失败，我收到带有以下消息的失败回调：

failed connection to socket.io: No session found

我会将所有代码放在这里，以便更容易发现我做错了什么。

var express  = require('express');
var app      = express();
var http     = require('http');
var socketio = require('socket.io')
var passportSocketIo = require('passport.socketio');
var port     = process.env.PORT || 3000;
var mongoose = require('mongoose');
var passport = require('passport');
var flash    = require('connect-flash');

var morgan       = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser   = require('body-parser');
var session      = require('express-session');
var MongoStore   = require('connect-mongo')(session);

var server   = http.createServer(app);
var io       = socketio.listen(server);

var dbConfig = require('./config/database.js');
mongoose.connect(dbConfig.url);
var sessionStore = new MongoStore({ db: mongoose.connection.db });

require('./config/passport')(passport);

app.use(morgan('dev'));
app.use(cookieParser());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.set('view engine', 'ejs');

app.use(session({
    key: 'connect.sid',
    secret: 'secret',
    store: sessionStore,
    resave: true,
    saveUninitialized: true
}));

app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
app.use(express.static(__dirname + '/public'));

require('./app/routes.js')(app, passport);

server.listen(3000, function() {
    console.log('App running on port: ' + port);
});

io.use(passportSocketIo.authorize({
    passport:     passport,
    cookieParser: cookieParser,
    key:          'connect.sid',
    secret:       'secret',
    store:        sessionStore,
    success:      onAuthorizeSuccess,
    fail:         onAuthorizeFail
}));

function onAuthorizeSuccess(data, accept){
  console.log('successful connection to socket.io');
  accept(null, true);
}

function onAuthorizeFail(data, message, error, accept){
  if(error)
    throw new Error(message);
  console.log('failed connection to socket.io:', message);
  accept(null, false);
}

io.sockets.on('connection', function(socket) {
    var date = new Date();
    var time = date.getHours() + ":" + date.getMinutes();
    socket.emit('message', {username: 'Server', message: 'welcome to the chat'});
    socket.on('send', function(data) {
        io.sockets.emit('message', data);
    });
});

我应该如何使用 socket.io 建立与会话的连接？

另外，我看到用户数据是通过socket.handshake.user. 在这种情况下是否正确？

为了清楚起见，版本如下：

express: 4.8.5
passport: 0.2.0
socket.io: 1.0.6
passport.socketio: 3.2.0

编辑

看来问题的一部分是已经存在的localhostvs错误。127.0.0.1但是，现在我没有得到任何握手数据。

首先，正如我在问题编辑中所指出的，请务必直接输入 IP，而不是使用localhost: 127.0.0.1。这是一个已知错误，当​​您指向localhost.

最后， passport-socketio Github 页面更新了以下内容，用于 socket.io 1.x 的授权回调。

function onAuthorizeSuccess(data, accept){
  console.log('successful connection to socket.io');
  accept();
}

function onAuthorizeFail(data, message, error, accept){
  console.log('failed connection to socket.io:', data, message);
  if(error)
    accept(new Error(message));
}

此外，握手数据不再存储在同一位置。替换socket.handshake.user为socket.request.user。

我有同样的问题。对我来说，解决方案不在 Web 服务器中，而是由于在浏览器中调用 localhost。更改为 127.0.0.1 或我的实际 IP 让生活更快乐。

passport.socketio不适用于新版本的 socket.io。

您应该能够删除passport.socketio并用这个替换您的当前io.use：

var cookieParser = require('cookie-parser')('secret'); // <- your secret here
io.use(function(socket, next){
    cookieParser(socket.handshake, {}, function(err){
        if (err) {
            console.log("error in parsing cookie");
            return next(err);
        }
        if (!socket.handshake.signedCookies) {
            console.log("no secureCookies|signedCookies found");
            return next(new Error("no secureCookies found"));
        }
        sessionStore.get(socket.handshake.signedCookies["connect.sid"], function(err, session){
            socket.session = session;
            if (!err && !session) err = new Error('session not found');
            if (err) {
                 console.log('failed connection to socket.io:', err);
            } else {
                 console.log('successful connection to socket.io');
            }
            next(err);
        });
    });
});

passport.socketio 包适用于以前版本的 socket.io。至少此代码适用于 socket.io v0.9.17 - https://github.com/vodolaz095/hunt/blob/v_0_2_x/lib/http/socket.io.js
