Expressjs + socket.io +快递会话 [英] Expressjs+socket.io+express-session

问题描述

  var app = require（'express'）（），
 session = require（'express-session'），
 cookie = require（'cookie'），
 cookieParser = require（'cookie-parser'），
 manager = './sockets/manager'）; 
 
 var sessionStore = new session.MemoryStore（）; 
 
 
 app.use（cookieParser（'secret'））; 
 app.use（session（{
 name：'sid'，
 store：sessionStore，
 secret：'secret'，
 saveUninitialized：true，
 resave：true，
 cookie：{
 path：'/'，
 httpOnly：true，
 secure：false，
 maxAge：null 
} 
}））; 
 
 var server = require（'http'）。Server（app）.listen（8888），
 io = require（'socket.io'）（server）; 
 
 io.use（function（socket，next）{
 var data = socket.request; 
 
 if（data.headers.cookie）{
 data.cookie = cookie.parse（cookieParser.signedCookie（data.headers.cookie，'secret'））; 
 
 console.log（'data.cookies（％s）'，JSON.stringify （data.cookie））; 
 // print'io = id_place'，cookie没有sid，为什么？
 
 if（data.cookie.sid）{
 data.sid = request.cookie.sid; 
 sessionStore.get（request.cookie.sid，function（err，session）{
 request.session = session; 
}）; 
} 
} 
 
 next（）; 
}）; 
 
 manager.use（io）; 
  

控制台日志向我显示此cookie request.cookies（{io：1HKSseNH5UrnJisSAAAA}）。
我刚刚看到很多例子与expressjs 3和socket 0.9，但我有：

socket.io： ^ 1.0.6，
express：〜4.5.1，
express-session：〜1.6.4

，它不起作用。

有任何错误吗？

解决方案

我为您创建了解决方案：在此输入链接说明。正如你可以看到套接字对象具有握手属性，其中包含带有cookie的请求头。

I have this code in my server.js.

var app = require('express')(),
        session = require('express-session'),
        cookie = require('cookie'),
        cookieParser = require('cookie-parser'),
        manager = require('./sockets/manager');

var sessionStore = new session.MemoryStore();


app.use(cookieParser('secret'));
app.use(session({
    name: 'sid',
    store: sessionStore,
    secret: 'secret',
    saveUninitialized: true,
    resave: true,
    cookie: {
        path: '/',
        httpOnly: true,
        secure: false,
        maxAge: null
    }
}));

var server = require('http').Server(app).listen(8888),
    io = require('socket.io')(server);

io.use(function(socket, next) {
    var data= socket.request;

    if (data.headers.cookie) {
        data.cookie = cookie.parse(cookieParser.signedCookie(data.headers.cookie, 'secret'));

        console.log('data.cookies ( %s )', JSON.stringify(data.cookie)); 
        // print 'io=id_place', cookies doesn't have sid, why?

        if (data.cookie.sid) {
            data.sid = request.cookie.sid;
            sessionStore.get(request.cookie.sid, function(err, session) {
                request.session = session;
            });
        }
    }

    next();
});

manager.use(io);

Console log shows me this cookie request.cookies ( {"io":"lHKSseNH5UrnJisSAAAA"} ). I've just seen many examples with expressjs 3 and socket 0.9, but I have:

"socket.io": "^1.0.6", "express": "~4.5.1", "express-session": "~1.6.4"

and it doesn't work.

Have I any mistakes?

解决方案

I've created solution for you: enter link description here. As you can see socket object has handshake property which include request headers with cookie.
