我的router/user.js代码如下

const express = require('express')
const Result = require('../models/Result')
const { login } = require('../services/user')
const { md5 } = require('../utils')
const { PWD_SALT } = require('../utils/constant')
const { body, validationResult } = require('express-validator')
const boom = require('boom')


const router = express.Router()

// 嵌套路由
router.post(
    '/login',
    [
        body('username').isEmail().withMessage('username类型不正确'),
        body('password').isLength({ min: 6 }).withMessage('password类型不正确')
    ],
    (req, res, next) => {
        const err = validationResult(req)
        if (!err.isEmpty()) {
            const [{ msg }] = err.errors
            next(boom.badRequest(msg))
        } else {
            const username = req.body.username
            const password = md5(`${req.body.password}${PWD_SALT}`)
            login(username, password).then(user => {
                if (!user || user.length === 0) {
                    new Result('登录失败').fail(res)
                } else {
                    new Result('登录成功').success(res)
                }
            })
        }
    })

router.get('/info', function (req, res, next) {
    res.json('user info...')
})


module.exports = router
