不能将套接字存储为数组中的对象

Question

我正在尝试将所有连接的套接字存储在像

这样的数组中

var basket = {};

io.sockets.on('connection', function (socket) {
  socket.on("register", function(user_profile) {
    basket[user_profile.id] = socket.id;
  });
 socket.on(SEND_INVITE,function(invitation_details){
         var to = basket[invitation_details.invitee];
          io.sockets.socket(to).emit(RECIEVE_INVITE,invitation_details);
    });
});

`

但是我不知道代码中有什么不对，只有最后加入的客户端才会存储在篮子里。请帮帮我

Answer 1

这就是我在我创建的项目中完成的方式。我使用了用户名作为密钥，而socket.id作为值。然后在客户端哈希中我使用socket.id作为键，并使用套接字作为值。这使我可以根据用户名轻松地向“有效”用户发送消息。

存储套接字detils并发出消息

var validUsers = {};
var clients = {};

io.sockets.on('connection', function (socket)
{    
  var hs = socket.handshake;
  if(hs.session)
  {
    if(hs.session.username)
    {
        clients[socket.id] = socket; // add the client data to the hash
        validUsers[hs.session.username] = socket.id; // connected user with its socket.id
    }
  }
    ...

  clients[validUsers[username]].emit('move-story', data); 
}

身份验证+获取会话

//Auth the user
io.set('authorization', function (data, accept) {
  // check if there's a cookie header
  if (data.headers.cookie) {
    data.cookie = parseCookie(data.headers.cookie);
    data.sessionID = data.cookie['express.sid'];

    //Save the session store to the data object
    data.sessionStore = sessionStore;

    sessionStore.get(data.sessionID, function(err, session){
      if(err) throw err;

      if(!session)
      {
        console.error("Error whilst authorizing websocket handshake");
        accept('Error', false);
      }
      else
      {
        console.log("AUTH USERNAME: " + session.username);
        if(session.username){
          data.session = new Session(data, session);
          accept(null, true);
        }else {
          accept('Invalid User', false);
        }
      }
    })
  } else {
    console.error("No cookie was found whilst authorizing websocket handshake");
    return accept('No cookie transmitted.', false);
  }
});
