node.js / express代码

var express = require('express'),
    app = express(),
    port = process.env.PORT || 3000,
    path = require('path');


app.use('/public', function (req, res) {
    res.sendfile(path.join(__dirname + '/public/index.html'));
});

app.use('/', function (req, res) {
    var data = '<h1>hello world</h1>';

    res.writeHead(200, {'Content-Type': 'text/html'});
    res.end(data)
});

app.listen(port);

console.log('server started at port %s ', port);

CSS代码

的.htaccess

AddType text/css .css
AddType text/javascript .js

node.js代码位于根目录中，html和css位于/ public subdir中。每次我加载我得到的一面：资源解释为Stylesheet，但用MIME类型text / html：“http：// localhost：3000 / css / app.css”传输。

我该如何解决这个问题？

var express = require('express'),
    app = express(),
    port = process.env.PORT || 3000,
    path = require('path');

app.use('/public', express.static('public'));
app.use('/', function (req, res) {
    res.sendfile(path.join(__dirname + '/index.html'));
});
app.listen(port);

console.log('Server started at http://localhost:%s/', port);

所以我重写了我的代码，如此，并且工作。它只在我使用express.static作为公共子网址时才发生变化。
