node js express validator分离文件问题

Question

我想制作一个注册文件并将其添加到我的 router.post('/register ..');

但是我遇到了一个问题。

他给我看了意想不到的“,”。谁能帮帮我？

register.js

'use strict';

const { body, validationResult } = require('express-validator');

const register = 
body('email').trim().isEmail().isLength({ min: 5, max: 100 }),
body('url').trim().isLength({ min: 5, max: 100}), async (req, res) => {

    const errors = validationResult(req);

    if (!errors.isEmpty()) {

        const data = errors.mapped();

        res.status(200).json({
            data
        });

    }
}


module.exports = register;

我想制作我可以这样写的文件：

const register = require('./register.js');

router.post('/register', register);

// register.js

'use strict';

const { body, validationResult } = require('express-validator');

module.exports = async (req, res) => {
await body('email').trim().isEmail().isLength({ min: 5, max: 100 }).run(req)
await body('url').trim().isLength({ min: 5, max: 100}).run(req)

const errors = validationResult(req);

if(!errors.isEmpty()) {
   const data = errors.mapped();
   // sends 400 with error data
   return res.status(400).json({data})
  }

 // Process request, generate data and sent to client
 const data = // reference data here
 res.status(200).json({data});
}

// routes.js

'use strict'

const router = require('express').Router()

router.post('/register', require('./register'))

module.exports = router
