node.js - 使用socket.IO err_connection_refused

Question

我正在使用 nodejs 和 socket.io 制作多人游戏。

当我在运行 Nodejs 的笔记本电脑上工作时，一切正常。我可以打开多个窗口选项卡并且我有多个用户。

但是当我尝试从旁边的另一台笔记本电脑连接到我的本地 IP(从 Node 服务器)时，我收到了 socket.io 错误

 "GET http://localhost:8000/socket.io/socket.io.js net::ERR_CONNECTION_REFUSED"

代码

 /**************************************************
** GAME INITIALISATION
**************************************************/
function init() {
// Declare the canvas and rendering context
canvas = document.getElementById("gameCanvas");
ctx = canvas.getContext("2d");

// Maximise the canvas
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;

// Initialise keyboard controls
keys = new Keys();

// Calculate a random start position for the local player
// The minus 5 (half a player size) stops the player being
// placed right on the egde of the screen
var startX = Math.round(Math.random()*(canvas.width-5)),
    startY = Math.round(Math.random()*(canvas.height-5));

// Initialise the local player
localPlayer = new Player(startX, startY);

socket = io.connect("http://localhost", {port: 8000, transports: ["websocket"]});

remotePlayers = [];

// Start listening for events
setEventHandlers();


};

已添加代码

  /**************************************************
 ** NODE.JS REQUIREMENTS
   **************************************************/
 var util = require("util"),                    // Utility resources (logging, object inspection, etc)
io = require("socket.io");              // Socket.IO
Player = require("./Player").Player;    // Player class


    /**************************************************
  ** GAME VARIABLES
 **************************************************/
 var socket,        // Socket controller
players;    // Array of connected players


  /**************************************************
   ** GAME INITIALISATION
   **************************************************/
 function init() {
// Create an empty array to store players
players = [];

socket = io.listen(8000);

socket.configure(function()
{
    socket.set("transports", ["websocket"]);
    socket.set("log level", 2);
});

setEventHandlers();

};

我重试将 localhost 替换为运行 Nodejs 服务器的 PC 的 IP 地址，结果确实有效。
