如何在nextjs中获取getinitial中的cookie？

npm install cookie-parser

const cookieParser = require('cookie-parser');

const cookieMiddleware = (req, res, next) => {
  cookieParser()(req, res, () => {
    next();
  });
};

module.exports = cookieMiddleware;

import cookieMiddleware from '../path/to/cookieMiddleware';

class MyPage extends React.Component {
  static async getInitialProps({ req }) {
    const cookies = req.cookies;
    // 处理获取到的cookie数据
    // ...
    return { cookies };
  }

  render() {
    // 渲染页面
    // ...
  }
}

export default MyPage;

const cookieMiddleware = require('./path/to/cookieMiddleware');

// ...

app.prepare().then(() => {
  const server = express();

  server.use(cookieMiddleware);

  // ...
});
