Passport.socketio有发现问题的问题 [英] Passport.socketio has issues finding session

问题描述

我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，我收到失败回调，并显示以下消息：

I am trying to access the session from sockets, but can't seem to make a connection. Without fail, authorization fails and I get the fail callback with the following message:

failed connection to socket.io: No session found

我将把我所有的代码放在这里，以便更容易找出我做错了。

I will place all my code here so that it might be easier to spot what I'm doing wrong.

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);
    });
});

如何使用socket.io建立与会话的连接？

How should I be establishing a connection to the session with socket.io?

此外，我看到用户数据通过 socket.handshake.user 访问。在这种情况下是否正确？

Also, I have seen that the user data is accessed via socket.handshake.user. Would that be correct in this case?

为了清楚起见，版本如下：

And for clarity, the versions are as follows:

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

编辑

问题是已经存在的 localhost 与 127.0.0.1 错误。然而，现在我没有得到任何握手数据。

It appears that part of the issue was the localhost versus 127.0.0.1 bug that already exists. However, now I don't get any handshake data back.

推荐答案

首先，正如我在我的问题编辑中指出的，请确保直接键入IP，而不是使用 localhost ： 127.0.0.1 。这是一个已知的错误，不能允许您在指向 localhost 时正确发送cookie。

First off, as I had noted in my question edit, be sure to type in the IP directly, rather than using localhost: 127.0.0.1. This is a known bug that will not allow you to send the cookie over correctly when pointing to localhost.

护照 - socketio Github页面最后更新了套接字的授权回调。 io 1.x。

The passport-socketio Github page was, at last, updated with the following for the authorization callbacks for socket.io 1.x.

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 。

Also, the handshake data is no longer stored in the same place. Replace socket.handshake.user with socket.request.user.
