Question

我在向特定客户端发送数据时遇到问题。

了Serverside

var io = require('socket.io').listen(app.listen(app.get('port')));

io.sockets.on('connection', function (socket) {

    socket.on('onHabboConnection', function (data) {
      socket.id = data.id; 
      socket.join(data.id);
      io.sockets.in(data.id).emit('onHabboConnected');
    });
    
    socket.on('onHabboConnected', function (data) {
      console.log("<" + socket.id + "> " + data.username + " has joined the game.");
    });
});

客户机侧

	  var socket = io.connect('http://localhost:3000');
               $( document ).ready(function() {
	 	socket.emit('onHabboConnection', { id:'<%= user.id %>' });
	 });

	  socket.on('onHabboConnected', function () {
	  	console.log("WORKING" );
	  	socket.emit('onHabboConnected', { username: '<%= user.username %>'});
	  });

  io.sockets.in(data.id).emit('onHabboConnected');

我尝试了所有方法，但它们都会抛出错误。这个不会抛出错误但不会做任何事情！

您正在覆盖在客户端生成的唯一标识socket.id。这就是为什么你在发光，但它不会去任何地方，因为那个客户端不存在：

socket.on('onHabboConnection', function (data) {
  //socket.id = data.id;  remove this
  socket.join(data.id);
  io.sockets.in(data.id).emit('onHabboConnected');
});

如果您想更改socket.id，请在客户端进行更改。
