这是我的 app.js 文件的骨架。
我不明白的是它不读取和打印“日志授权”的方式。我跟着这个https://github.com/LearnBoost/socket.io/wiki/Authorizing

var express = require('express');
mongoose = require('mongoose');
var MongoStore = require('connect-mongo')(express);
app = express();

// costants
var SITE_SECRET = 'xxx';

// mongoose
mongoose.connect('mongodb://127.0.0.1/test');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function callback () {
    console.log('Mongoose connection is now opened');
});

// pass same objects from Express to Socket.IO so they match
var parseCookie = express.cookieParser(SITE_SECRET);
var store = new MongoStore({
  mongoose_connection: mongoose.connection,
  db: mongoose.connections[0].db
});

app.configure(function(){
    app.set('host', '127.0.0.1');
    app.set('port', 1111);
    // init cookie-session
    app.use(parseCookie);
    app.use(express.session({
        secret : SITE_SECRET
        ,store  : store
        ,cookie: { maxAge: new Date(Date.now() + (1000*60*60*24*30*12)) }
    }));
});

// create and start server
var server = require('http').createServer(app)
server.listen(app.get('port'));

// socket.io
var io = require('socket.io').listen(8080);

io.configure(function() {
  console.log('log configure <-- it read this. ok!');
  io.set('authorization', function(handshake, callback) {
    console.log("log authorisation <-- but it doesn't read this. why??");
    if (handshake.headers.cookie) {
      parseCookie(handshake, null, function() {
       handshake.sessionID = handshake.signedCookies['connect.sid'];
        store.get(handshake.sessionID, function(err, session) {
            callback(null, true);
        });
      });
    } else {
      // they client has no session yet, don't let them connect
      callback('No session.', false);
    }
  });
});

clients = {};
io.sockets.on('connection', function (socket) {
  // save to a global object
  console.log('save session');
  var session = socket.handshake.sessionID;
  clients[session] = socket;
  socket.on('disconnect', function() {
    console.log('remove session');
    delete clients[session];
  });
});

// routes
app.get('/on', function(req, res){
  var socket = clients[req.sessionID];
  socket.on('test', function (data) {
   console.log(data);
  });
});
app.get('/emit', function(req, res){
  var socket = clients[req.sessionID];
  socket.emit('test', "ciao");
  console.log("emit");
});

当我在终端上启动服务器时，我看到了这个：

starting `node app.js`
Mongoose connection is now opened
info  - socket.io started
log configure

如果我加载页面“/ on”，错误是：

TypeError: Cannot call method 'on' of undefined

我在这里堆积太多......这有什么问题？
也许有人有同样的问题......

尝试socket.io监听server端口，您定义1111为服务器的端口，8080对于socket.io，您的应用程序可用于访问localhost:1111。

简短的例子

var server = http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
});

io.listen(server);
