node.js - socket.get() 和 socket.set() 出现问题

Question

我正在使用 NodeJs v0.10.28，每次我尝试登录聊天时都会收到错误

TypeError: Object #<Socket> has no method 'set' at Socket.<anonymous>

如果我删除行，它可以工作但不能正常工作。

这段代码有什么问题

// get the name of the sender
socket.get('nickname', function (err, name) {
  console.log('Chat message by ', name);
  console.log('error ', err);
  sender = name;
}); 

和

socket.set('nickname', name, function () {
  // this kind of emit will send to all! :D
  io.sockets.emit('chat', {
    msg : "Welcome, " + name + '!', 
    msgr : "Nickname"
  });
});

您必须直接在套接字中设置昵称属性!

来自 socket.io 网站:

The old io.set() and io.get() methods are deprecated and only supported for backwards compatibility. Here is a translation of an old authorization example into middleware-style.

此外，来自 socket.io 网站的示例:

// usernames which are currently connected to the chat
var usernames = {};
var numUsers = 0;

    // when the client emits 'add user', this listens and executes
  socket.on('add user', function (username) {
    // we store the username in the socket session for this client
    socket.username = username;
    // add the client's username to the global list
    usernames[username] = username;
    ++numUsers;
    addedUser = true;
    socket.emit('login', {
      numUsers: numUsers
    });
    // echo globally (all clients) that a person has connected
    socket.broadcast.emit('user joined', {
      username: socket.username,
      numUsers: numUsers
    });
  });
