如何在现有的node.js express设置中集成速率限制-灵活？

npm install express-rate-limit

const express = require('express');
const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 60 * 1000, // 1分钟
  max: 10, // 最大请求数量
});

app.use(limiter);

const express = require('express');
const rateLimit = require('express-rate-limit');

const app = express();

const limiter = rateLimit({
  windowMs: 60 * 1000, // 1分钟
  max: 10, // 最大请求数量
});

app.use(limiter);

app.get('/', (req, res) => {
  res.send('Hello World!');
});

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