路由传递params参数（useParams和useRouteM

umi3采用的是都是React Router5，hooks传递参数使用useParams和useRouteMatch等方式。

但是父级路由是无法访问子路由的参数的，比如

{
    path: '/parent',
    component: '@/components/ParentLayout',
    routes: [
      {
        path: '/parent/info/:id',
        component: './parent/Info',
      },
      {
        path: '/parent/optInfo/:id',
        component: './parent/OptInfo',
      },
    ],
  },

应改为：

{
    path: '/parent/:type/:id',
    component: '@/components/ParentLayout',
    routes: [
      {
        path: '/parent/info/:id',
        component: './parent/Info',
      },
      {
        path: '/parent/optInfo/:id',
        component: './parent/OptInfo',
      },
    ],
  },

通过useParams获取参数

import { useParams, useRouteMatch } from 'umi'
console.log(useParams())
