我需要在套接字之间共享会话并表达 js。我试图让这个例子工作:http ://www.danielbaulig.de/socket-ioexpress/没有成功。网页浏览器返回

GET localhost:8000/socket.io/1/?t=1354005884872 500(内部服务器错误)

在会话开始时。我收到服务器端错误:

warn - 握手错误 Error

服务器端脚本:

var express = require('express')
  , util = require('util')
  , connect = require('express/node_modules/connect')
  , parseCookie = connect.utils.parseCookie
  , MemoryStore = connect.middleware.session.MemoryStore
  , store;

  var app = express()
  , http = require('http')
  , server = http.createServer(app)
  , io = require('socket.io').listen(server);

  var connect = require('express/node_modules/connect')
  , util = require('util')
  , cookie = require('cookie')
  , parseCookie = cookie.parse
  , MemoryStore = connect.middleware.session.MemoryStore
  , store;

app.configure(function () {
    app.use(express.cookieParser());
    app.use(express.session({
      secret: 'secret'
    , key: 'express.sid'
    , store: store = new MemoryStore()
    }));
    app.use(function (req, res) {
        res.send('Hello, your session id is ' + req.sessionID);
    });
});

io.set('authorization', function (data, accept) {
  if (!data.headers.cookie) 
    return accept('No cookie transmitted.', false);

  data.cookie = parseCookie(data.headers.cookie);
  data.sessionID = data.cookie['express.sid'];

  store.load(data.sessionID, function (err, session) {
    if (err || !session) return accept('Error', false);

    data.session = session;
    return accept(null, true);
  });
}).sockets.on('connection', function (socket) {
  var sess = socket.handshake.session;
  socket.log.info(
      'a socket with sessionID'
    , socket.handshake.sessionID
    , 'connected'
  );
  socket.on('set value', function (val) {
    sess.reload(function () {
      sess.value = val;
      sess.touch().save();
    });
  });
});

app.use(count);

// custom middleware
function count(req, res) {
  req.session.count = req.session.count || 0;
  var n = req.session.count++;
  res.send('viewed ' + n + ' times\n');
}

server.listen(8000);

客户端脚本:

<%= javascript_include_tag "http://localhost:8000/socket.io/socket.io.js" %>
var socket = io.connect('http://localhost:8000');

socket.io v0.9.11、express.js v3.0.3、connect v2.7.0、cookie v0.0.5

我希望你能帮助我。

刚刚遇到一个可能有助于为您简化一切的项目。Express.io 结合了 express 和 socket.io,并包含了一堆易于使用的示例: https ://github.com/techpines/express.io

我自己只是玩弄了一点,但它看起来很有希望。希望这可以帮助。
