Question

我正在使用带有socket.io的nodejs进行多人游戏。

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标签，我有多个用户。

但是当我尝试从我旁边的另一台笔记本电脑连接到我的本地IP（来自节点服务器）时，我收到了socket.io的错误

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

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();

};

Answer 1

我重新尝试将localhost替换为运行nodejs服务器的PC的IP地址，但它确实有效。

Answer 2

以下是我为socket.io设置工作节点服务器的方法。也许这会有所帮助。

var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.use(express.static(__dirname + '/'));

app.get('/', function(req, res){
    res.sendfile('index.html');
});

io.on('connection', function(socket){
    // on connection from the client this is where you can do stuff like...
    //socket.emit('message', JSON.stringify(yourdataobj));
}
});

http.listen(3000, function(){
    console.log('listening on *:3000');
});

然后，在客户端html（您在上面提供的index.html）中，以下是关键行。

在头部：

<script src="/socket.io/socket.io.js"></script>

在关闭正文标记之前：

<script>
var socket = io();

socket.on('message', function(msg){
    console.log(msg);
});
</script>

另外，请返回socket.io网站以获取有关如何设置所有内容的提醒和复习：http://socket.io/get-started/chat/

使用socket.IO进行err_connection_refused
