错误 node.js 无法加载资源

Question

我一直在使用 node.js 和 socket.io，并按照教程进行操作，但我不断从我正在构建的应用程序中收到错误消息。这是我的 server.js 文件：

var static = require('node-static');
var http = require('http');
var file = new(static.Server)();
var app = http.createServer(function(req, res) {
    file.serve(req, res);
}).listen(1234);
var io = require('socket.io').listen(app);
io.sockets.on('connection', function(socket) {
    function log() {
        var array = [">>> Message from server: "];
        for (var i = 0; i < arguments.length; i++) {
            array.push(arguments[i]);
        }
        socket.emit('log', array);
    }
    socket.on('message', function(message) {
        log('Got message:', message);
        socket.broadcast.emit('message', message);
    });
    socket.on('create or join', function(room) {
        var numClients = io.sockets.clients(room).length;
        log('Room ' + room + ' has ' + numClients + ' client(s)');
        log('Request to create or join room ' + room);
        if (numClients === 0) {
            socket.join(room);
            socket.emit('created', room);
        } else if (numClients === 1) {
            io.sockets.in(room).emit('join', room);
            socket.join(room);
            socket.emit('joined', room);
        } else { // max two clients
            socket.emit('full', room);
        }
        socket.emit('emit(): client ' + socket.id + ' joined room ' + room);
        socket.broadcast.emit('broadcast(): client ' + socket.id + 'joined room' + room);
    });
});

但是，当我浏览到 localhost:1234 时，我收到错误 Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:1234

将 index.html 放在您的应用根文件夹中，它将通过“node-static”作为入口文件提供。

更简洁的方法是为所有前端文件配置一个文件夹。

var file = new static.Server('./public');
