我想通过Node.js使用express()函数在localhost：3000中将CSS添加到我的HTML中。 不幸的是，有些奇怪。我一步一步按照教程中的步骤，但仍然无法加载我的CSS。我的style.css在css文件夹(css/style.css)。这里是我的代码：

app.js(请注意，我用的应用程序和应用1)CSS无法使用Node.js加载到我的HTML代码中

var app = require('http').createServer(handler);

var io = require('socket.io').listen(app);

var fs = require('fs');

var express = require('express');

var app1 = express();

var mySocket = 0;

app1.use(express.static('/css'));

app.listen(3000); //Which port are we going to listen to?

function handler (req, res) {

fs.readFile(__dirname + '/index.html', //Load and display outputs to the index.html file

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) {

console.log('Webpage connected'); //Confirmation that the socket has connection to the webpage

mySocket = socket;

});

//UDP server on 41181

var dgram = require("dgram");

var server = dgram.createSocket("udp4");

server.on("message", function (msg, rinfo) {

console.log("Broadcasting Message: " + msg); //Display the message coming from the terminal to the command line for debugging

if (mySocket != 0) {

mySocket.emit('field', "" + msg);

mySocket.broadcast.emit('field', "" + msg); //Display the message from the terminal to the webpage

}

});

server.on("listening", function() {

var address = server.address(); //IPAddress of the server

console.log("UDP server listening to " + address.address + ":" + address.port);

});

server.bind(41181);

的style.css(CSS/style.css文件)

.test

{

color:red;

}

指数.html

var socket = io.connect('http://localhost:3000');

socket.on('field', function (data) {

console.log(data);

$("#field").html(data);

});

你有没有在控制台中的任何错误的最小工作的例子吗？例如，像style.css的404一样。 –

'css'文件的URL以'/'开头。确保'localhost'的根目录包含'css'文件夹。 –
