将中间件添加到单个路由Js Express的最简洁方法

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

const middlewareFunction = (req, res, next) => {
  // 在这里执行中间件的逻辑
  console.log('执行中间件');
  next(); // 调用next()将控制权传递给下一个中间件或路由处理程序
};

app.use('/api', middlewareFunction);

app.get('/api/users', (req, res) => {
  // 在这里处理路由请求
  res.send('处理用户请求');
});

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

const middlewareFunction = (req, res, next) => {
  console.log('执行中间件');
  next();
};

app.use('/api', middlewareFunction);

app.get('/api/users', (req, res) => {
  res.send('处理用户请求');
});

app.listen(3000, () => {
  console.log('服务器已启动');
});
