无线路由器该如何设置呢？

Route Matchers

·<Switch> &<Route>
- when a <Switch> is rendered, it searches through its children <Route>
elements to find one whose path matches the current URL
- when it finds one, it renders that <Route> and ignores all others
- if no <Route> matches,the <Switch> renders nothing(null)
render(){
return(
<Router>
<Switch>
<Route path="/about"><About /></Route>
<Route path="/users">Users /></Route>
<Route path="/"<Home/></Route>
</Switch>
</Router>
