我是NodeJS / Express的新手，我正在开发一个简单的服务器应用程序来更新客户端窗口中的时钟。我一直在使用Chrome进行开发，一切都运行良好。但是，当我稍后在Firefox中尝试该应用程序时，我注意到没有应用任何CSS规则。我查看了Firefox调试器屏幕中的“网络”选项卡，确认浏览器已成功获取CSS文件。所以我的问题是，为什么CSS在Chrome上正确加载而在Firefox上没有？一个解决方案很好，但我也有兴趣了解这里发生了什么，或者我做错了什么。
请注意，CSS文件位于./public/css/link-server.css
这是我的代码（我也对我的nodejs / express代码和组织的一般改进持开放态度）：
var express = require('express');
var app = express();
var favicon = require('serve-favicon');
app.use(express.static(__dirname + '/public'));
app.use(favicon(__dirname + '/public/images/favicon.ico'));
var fs = require('fs');
var http = require('http').Server(app);
var io = require('socket.io')(http);
var AIN_PATH = '/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0'
app.get('/', function(req, res){
res.sendFile(__dirname+'/link-server.html');
});
function pad(n) {
return (n < 10) ? ("0" + n) : n;
}
setInterval(function() {
var date = new Date();
var hours = date.getHours();
var minutes = pad(date.getMinutes());
var seconds = pad(date.getSeconds());
var timeString = hours + ":" + minutes + ":" + seconds;
io.sockets.emit('timer', { time: timeString });
//console.log(timeString);
}, 1000);
io.on('connection', function(socket){
console.log('Connected to client.');
socket.on('disconnect', function(){
console.log('Client disconnected.');
});
});
http.listen(2000, function(){
console.log('listening on *:2000');
});
