推荐答案
问题是您使用 index.html 回答每个请求。这意味着如果Web浏览器发送<$ c $请求c> style.css 它仍然获取html。您可以查看浏览器控制台以验证这一点。要提供不同的文件，您可能需要检查 request.url 准确提供客户端文件想要：
The problem is that you answer every request with index.html. That means if the web browser sends a request for style.css it still gets the html. You could look into your browsers console to verify this. To serve different files, you might wanna check request.url to serve exactly the file the client wants to:
const http = require('http');
const fs = require('fs');
http.createServer(function (req, res) {
if(req.url === "/index.html" || req.url === "/"){
fs.readFile('index.html', function(err, data) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data);
res.end();
});
} else if(req.url === "/style.css"){
fs.readFile('style.css', function(err, data) {
res.writeHead(200, {'Content-Type': 'text/css'});
res.write(data);
res.end();
});
}
}).listen(8080);
如果您认为许多不同的文件变得讨厌，您可以使用允许静态目录服务的库，例如快递
If you think that gets nasty for many different files, you may use a library that allows static directory serving, e.g. express
