中间件

中间件添加使用 router.use，跟路由一样，注册的顺序也是很重要的。中间件会在每个匹配路由的 handler 执行前，先执行一遍

import SMERouter from 'sme-router'

const router = new SMERouter('router-view')

router.use((req) => {
  req.body.count += 3
})

router.use((req) => {
  req.body.count *= 2
})

router.use((req) => {
  req.body.order = `NO.${req.body.count}`
})

router.route('/user/:name', (req, res, next) => {
  console.log(req.body.count) // output => 8
  console.log(req.body.order) // output => NO.8
})

router.go('/user/Leo', { count: 1 })
