Question

https://github.com/xpepermint/socket.io-express-session 这是我尝试过的众多方法之一。我也尝试了所有这些答案： How to share sessions with Socket.IO 1.x and Express 4.x? 还有一些......这一切都给了我相同的结果：

抛出新的TypeError（“参数'url'必须是字符串，而不是”+ typeof URL） ^ TypeError：参数'url'必须是字符串，而不是未定义

我已经尝试过我在互联网上找到的所有解决方案，基本上一切都会让我遇到同样的错误。在某些时候，我只是尝试复制和粘贴找到的例子，他们给我完全相同的结果。我猜其中一个中间件更新后出了问题。怎么解决？是否有另一种可靠的方式与socket.io共享快速会话？

var Session = require('express-session');
var session = Session({ secret: 'pass', resave: true, saveUninitialized: true });
var cookieParser = require('cookie-parser');

var express = require('express');
var app = express();


app.use(cookieParser());
app.use(session); // session support
app.get('/', function (req, res) {
  req.session.uid = 1;
  res.send('Hi user #' + req.session.uid);
});


var http = require('http').createServer(app);
http.listen(3000, function(){
    console.log('listening on *:3000');
});

var ios = require('socket.io-express-session');
var io = require('socket.io')(http);
io.use(ios(session)); // session support
io.on('connection', function(socket){
  console.log(socket.handshake.session);
});

上面是一个返回此错误的示例。

Answer 1

使用io.use（...）

时，会出现错误

问题是会话中间件期望在req.orginalUrl中找到会话。套接字没有orginalUrl。要解决这个问题，只需指定一个......

io.use(function(socket, next){
  socket.request.originalUrl = socket.request.url;
  session(socket.request, socket.request.res, next);
});

下一个问题是会话（...）希望解析cookie。我们可以使用Cookie-parser＆＃39;为此：

var cookieParse = cookieParser();
  io.use(function(socket, next){
  cookieParse(socket.request, socket.request.res, next);
});

之后我们可以简单地桥接护照和socket.io：

var passInit = passport.initialize();
var passSess = passport.session();
io.use(function(socket, next){
  passInit(socket.request, socket.request.res, next);
});
io.use(function(socket, next){
  passSess(socket.request, socket.request.res, next);
});

现在我们的io.on（＆＃39;连接＆＃39;）我们可以看到socket.request.user

io.on('connection', function(socket){
  console.log("socket connection");
  console.log(socket.request.user)
  console.log(socket.request.session.passport.user);
});

使用Bradley Lederholz的答案，这就是我让它自己运作的方式。有关更多解释，请参阅Bradley Lederholz的答案。

var app = express();
var server  = require('http').createServer(app);
var io = require('socket.io');
var cookieParse = require('cookie-parser')();
var passport = require('passport');
var passportInit = passport.initialize();
var passportSession = passport.session();
var session = require('express-session');
var mongoStore = require('connect-mongo')(session);
var mongoose = require('mongoose');
var sessionMiddleware = session({
  secret: 'some secret',
  key: 'express.sid',
  resave: true,
  httpOnly: true,
  secure: true,
  ephemeral: true,
  saveUninitialized: true,
  cookie: {},
  store:new mongoStore({
  mongooseConnection: mongoose.connection,
  db: 'mydb'
  });
});

app.use(sessionMiddleware);
io = io(server);
io.use(function(socket, next){
  socket.client.request.originalUrl = socket.client.request.url;
  cookieParse(socket.client.request, socket.client.request.res, next);
});

io.use(function(socket, next){
  socket.client.request.originalUrl = socket.client.request.url;
  sessionMiddleware(socket.client.request,   socket.client.request.res, next);
});

io.use(function(socket, next){
  passportInit(socket.client.request, socket.client.request.res, next);
});

io.use(function(socket, next){
  passportSession(socket.client.request, socket.client.request.res, next);
});

io.on('connection', function(socket){
  ...
});

... 
server.listen(8000);

将快速会话传递给socket.io
