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，我得到失败回调，并带有以下消息：
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，我已经看到用户数据是通过socket.handshake.user访问的。在这种情况下，这是否正确？
为清楚起见，版本如下：
express: 4.8.5
passport: 0.2.0
socket.io: 1.0.6
passport.socketio: 3.2.0
修改
问题的一部分似乎是已存在的localhost与127.0.0.1错误。但是，现在我没有得到任何握手数据。
答案 0 :(得分：3)
首先，正如我在编辑问题中所述，请务必直接输入IP，而不是使用localhost：127.0.0.1。这是一个已知的错误，当您指向localhost时，它不允许您正确发送cookie。
最后，使用以下内容更新了passport-socketio Github page，以获取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个地方。将socket.handshake.user替换为socket.request.user。
答案 1 :(得分：1)
我遇到了完全相同的问题。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或我的实际知识产权让生活变得更加快乐。
答案 2 :(得分：0)
passport.socketio 不适用于新版本的socket.io。
您应该可以删除 passport.socketio 并将当前io.use替换为此<：p>
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包与先前版本的socket.io一起使用。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
