我是Node和Socket.io的新手,并试图让下面的代码运行。它旨在为WebSocket请求提供服务,但是我想修改它以提供静态内容,例如index.html。
我的网络套接字代码如下:
var http = require("http"),
sys = require("sys"),
io = require("socket.io"),
GlobTrie = require("glob-trie.js");
var Brokaw = {};
Brokaw.Server = function(port) {
var self = this;
// setup the basic HTTP server -- socket.io will wrap this
var server = http.createServer(function(req, res) {
// We have to respond with something, otherwise the connections hang :(
res.writeHead(404);
res.close();
});
server.listen(port);
this._io = io.listen(server, { "resource": "brokaw" });
this._trie = new GlobTrie();
this._io.on("connection", function(conn) {
new Brokaw.Server.Client(conn, self);
});
};
new Brokaw.Server(8080);
我为index.html提供服务的代码如下:
// Hardcode *all* HTTP requests to this server to serve up index.html
fs.readFile(
__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
}
);
有人可以建议如何整合两者,即修改顶级代码以提供我的index.html文件吗?
感谢任何评论,我一直在努力奋斗好几个小时!
问候,本。

有一个例子,取自官方Socket.IO homepage:
服务器侧强>:
var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs')
app.listen(80);
function handler (req, res) {
fs.readFile(__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
<强>客户端强>:
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost');
socket.on('news', function (data) {
console.log(data);
socket.emit('my other event', { my: 'data' });
});
</script>
