如何在Redis中缓存整个next.js的HTML页面？

import redis from 'redis';
import { promisify } from 'util';

const redisClient = redis.createClient();

// 使用promisify将Redis的get和set方法转换为Promise形式
const getAsync = promisify(redisClient.get).bind(redisClient);
const setAsync = promisify(redisClient.set).bind(redisClient);

const cacheMiddleware = async (req, res, next) => {
  const key = req.url;

  // 尝试从Redis中获取缓存的页面
  const cachedPage = await getAsync(key);

  if (cachedPage) {
    // 如果页面已经被缓存，则直接返回缓存的HTML页面
    res.send(cachedPage);
  } else {
    // 如果页面没有被缓存，则继续处理请求，并将生成的HTML页面缓存到Redis中
    res.sendResponse = res.send;
    res.send = async (body) => {
      await setAsync(key, body);
      res.sendResponse(body);
    };

    next();
  }
};

export default cacheMiddleware;

import App from 'next/app';
import cacheMiddleware from '../path/to/cacheMiddleware';

class MyApp extends App {
  // ...

  static async getInitialProps(appContext) {
    // ...

    // 将cacheMiddleware中间件应用到整个应用程序上
    appContext.ctx.app.use(cacheMiddleware);

    // ...
  }

  // ...
}

export default MyApp;
