根上的入口与路径上的入口冲突

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

// 根路径处理
app.get('/', (req, res) => {
  res.send('Welcome to the homepage');
});

// 特定路径处理
app.get('/users', (req, res) => {
  res.send('List of users');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

function authenticate(req, res, next) {
  if (req.isAuthenticated()) {
    return next();
  }
  res.redirect('/login');
}

app.use(authenticate); // 应用于所有路径

app.get('/', (req, res) => {
  res.send('Welcome to the homepage');
});

app.get('/users', (req, res) => {
  res.send('List of users');
});

// services/userService.js
exports.getUsers = () => {
  // 获取用户列表的逻辑
};

// routes/users.js
const express = require('express');
const router = express.Router();
const userService = require('../services/userService');

router.get('/', (req, res) => {
  const users = userService.getUsers();
  res.json(users);
});

module.exports = router;

// app.js
const express = require('express');
const app = express();
const usersRouter = require('./routes/users');

app.use('/users', usersRouter);

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
