React路由的使用 Redirect默认展示某一个页面 Switch找到停止 BrowserRouter和HashRouter 的区别

App.js
    import {Link,Route,NavLink,Redirect,Switch} from "react-router-dom"
    <NavLink to="/chuli" activeClassName="demo">Chuli</NavLink>
    <NavLink to="/clock" activeClassName="demo">Clock</NavLink>
    <Switch>
    <Route path="/Chuli" component={Chuli}></Route>
    <Route path="/Clock" component={Clock}></Route>
    <Redirect to="/chuli"></Redirect> //默认展示chuli页面
    </Switch>
