node.js - Passport.socketio 在查找 session 时出现问题

Question

我正在尝试从套接字访问 session ，但似乎无法建立连接。如果没有失败，授权就会失败，并且我会收到带有以下消息的失败回调:

failed connection to socket.io: No session found

我将把所有代码放在这里，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);
    });
});

我应该如何与 socket.io 建立与 session 的连接？

此外，我还发现用户数据是通过 socket.handshake.user 访问的。在这种情况下这是正确的吗？

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

问题的一部分似乎是 localhost 与已经存在的 127.0.0.1 错误有关。但是，现在我没有收到任何握手数据。

Answer 1

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 时，该错误将不允许您正确发送 cookie。

Passport socket Github page最后，针对 socket.io 1.x 的授权回调更新了以下内容。

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。将 socket.handshake.user 替换为 socket.request.user。
