Express服务器无法加载CSS静态文件?

我已经使用中间件加载了静态CSS文件,但无法正常工作。当我简单地打开不带服务器的html / ejs文件时,将加载CSS。但是,当我使用快递服务器执行相同操作时,它不起作用。

在开发人员工具的网络部分中,css文件显示404错误。

快递代码:

//express
const express = require('express');
const app = express();

const path = require('path');

app.set('view engine' , 'ejs');

//middleware
app.use(express.static(path.join(__dirname, 'public')));

//home route
app.get('/' , (req , res) =>{
    res.render('todosample');
});

//listning to port
app.listen(8080);

文件结构为:

public
    todosamplestyle.css
views
    todosample.ejs
app.js

HTML文件:

        </ul>

答案 0 :(得分:0)

您正在使用express.static上的/共享CSS文件。因此,您的CSS文件的路径为:http://host:port/todosamplestyle.css

您正在渲染/路线。这意味着您的CSS路径将为./todosamplestyle.css

如果您想在静态变量前加上/public,则可以通过

app.use('/public', express.static('public'))
