如何从服务器获取nuxt格式的当前日期？

const getDate = () => {
  const date = new Date();
  const year = date.getFullYear();
  const month = String(date.getMonth() + 1).padStart(2, '0');
  const day = String(date.getDate()).padStart(2, '0');
  return `${year}-${month}-${day}`;
};

module.exports = getDate;

async asyncData({ app }) {
  const getDate = await app.$axios.$get('/api/getDate');
  return { currentDate: getDate };
}

serverMiddleware: [
  { path: '/api', handler: '~/api/index.js' }
]

const express = require('express');
const app = express();
const getDate = require('./getDate');

app.get('/getDate', (req, res) => {
  const currentDate = getDate();
  res.json(currentDate);
});

module.exports = app;
