Express request.route

TIP

包含当前匹配的路由，一个字符串。

req.route

app.get('/user/:id?', (req, res) => {
  console.log(req.route)
  res.send('GET')
})

输出结果：

{ path: '/user/:id?',
  stack:
   [ { handle: [Function: userIdHandler],
       name: 'userIdHandler',
       params: undefined,
       path: undefined,
       keys: [],
       regexp: /^\/?$/i,
       method: 'get' } ],
  methods: { get: true } }
