如何使用快递在“公共”中提供文件夹

Question

I am trying to serve the login page in my public folder in express, so far i have been unable to do so. I tried to work the path but I don't know why it does not work. What I want to have is that I can have more code in the callback but because of the way it is now I can do that, when I try to make the callback a full function it won't work either.

My folder structure
- root
  - server
    - server.js
  - public
    - login
      - index.html

 const express = require('express'); const app = express(); const path = require('path'); app.listen(4000); console.log('server started\\n'); app.get('/', () => app.use(express.static(__dirname + '/public/login'))); // what i want to have app.get('/', () => { // serve file });

Answer 1

You should mount the static file serving directly when the server starts, not after the first request arrives so this line:

app.get('/', () => app.use(express.static(__dirname + '/public/login')));

has to be:

app.use(express.static(__dirname + '/../public/login'));

You also have to go up one folder as the code is started in the /server/ directory, which can be done with /../ .

If you only want to server the index.html from public folder instead of all files in there, what you can do is

app.get('/', (req, res) => res.sendFile('index.html', { root: __dirname + '/../public/login'));
