javascript - Socket.io 授权功能不更新 session 数据

Question

我正在尝试使用 Socket.IO 的授权功能来获取 session 数据。问题是即使我注销并销毁我的 session ，Socket.IO 仍然有旧的 session 信息，这显然不理想。知道我在下面的代码中做错了什么吗？

io.set('authorization', function (data, accept) {
    if(data.headers.cookie) {
        data.cookie = parseCookie(data.headers.cookie);
        data.sessionID = data.cookie['express.sid'];
        app.set('mongo-store').get(data.sessionID, function (err, session) {
            console.log(err, session);
      if (err || !session) {
                // if we cannot grab a session, turn down the connection
                accept('Error', false);
      } else {
        // save the session data and accept the connection
        data.session = session;
        accept(null, true);
      }
        });
    } else {
        return accept('No cookie transmitted.', false);
    }
    accept(null, true);
});

这是连接代码:

io.sockets.on('connection', function(socket) {  

  var hs = socket.handshake;
  console.log('A socket with sessionID ' + hs.sessionID 
      + ' connected!');
  // setup an inteval that will keep our session fresh
  var intervalID = setInterval(function () {
      // reload the session (just in case something changed,
      // we don't want to override anything, but the age)
      // reloading will also ensure we keep an up2date copy
      // of the session with our connection.
      hs.session.reload( function () { 
          // "touch" it (resetting maxAge and lastAccess)
          // and save it back again.
          hs.session.touch().save();
      });
  }, 60 * 1000);
  socket.on('disconnect', function () {
      console.log('A socket with sessionID ' + hs.sessionID 
          + ' disconnected!');
      // clear the socket interval to stop refreshing the session
      clearInterval(intervalID);
  });
});

sio.sockets.on('connection', function (socket) {
    var hs = socket.handshake;
    console.log('A socket with sessionID ' + hs.sessionID 
        + ' connected!');
    // setup an inteval that will keep our session fresh
    var intervalID = setInterval(function () {
        // reload the session (just in case something changed,
        // we don't want to override anything, but the age)
        // reloading will also ensure we keep an up2date copy
        // of the session with our connection.
        hs.session.reload( function () { 
            // "touch" it (resetting maxAge and lastAccess)
            // and save it back again.
            hs.session.touch().save();
        });
    }, 60 * 1000);
    socket.on('disconnect', function () {
        console.log('A socket with sessionID ' + hs.sessionID 
            + ' disconnected!');
        // clear the socket interval to stop refreshing the session
        clearInterval(intervalID);
    });

});

编辑:授权码

io.set('authorization', function (handshakeData, callback) {
  var cookie;
  // console.log(handshakeData.headers);
  if (handshakeData.headers && handshakeData.headers.cookie) {
    cookie = parseCookie(handshakeData.headers.cookie);
    // where SessionStore is an instance of your mongo store
    SessionStore.load(cookie['sioapp.sid'], function (err, session) {
      if (err) {
        // if we cannot grab a session, turn down the connection
        console.log(err);
      } else {
        // console.log('Successfully decoded the session: ', session);
        handshakeData.session = session;
      }
    });
  }
  callback(null, true); // error first callback style
});

每 60 秒一次， session 被触摸(因此刷新)。当用户断开连接时， session 将被销毁。
