服务端 app.js

var app = require('http').createServer(handler)var io = require('socket.io')(app);var fs = require('fs');var url = require("url");app.listen(80);function handler (req, res) {  var pathname = url.parse(req.url).pathname;  if(pathname == "/") {    pathname = "/index.html";  }  fs.readFile(__dirname + pathname, 'utf-8',  function (err, data) {    if (err) {      res.writeHead(500);      return res.end('Error loading ' + pathname);    }    res.writeHead(200,{'Content-Type':'text/html;charset=utf-8'});    res.end(data);  });}io.on('connection', function (socket) {  socket.emit('news', { hello: 'world' });  socket.on('my other event', function (data) {    console.log(data);  });  socket.on('disconnect', function (data) {    console.log('disconnect:' + data);  });});

说明：

1、如果没有指定默认页，默认加载/index.html页面

2、主要是通过这句话来支持中文 res.writeHead(200,{'Content-Type':'text/html;charset=utf-8'});

 

客户端 index.html
