如何在Nuxt静态文件的生产响应中添加CORS头部？

export default function (req, res, next) {
  res.setHeader('Access-Control-Allow-Origin', '*');
  res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
  res.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
  next();
}

export default {
  // ...
  serverMiddleware: [
    { path: '/api', handler: '~/middleware/cors.js' }
  ],
  // ...
}
