react-router-dom V6的配置使用实践

//V5版本
 import {Route, Switch} from 'react-router-dom';
 
<div>
    <Switch>
        ......
        ......
    </Switch>
 </div>
//V6版本
 import {Route, Routes } from 'react-router-dom';
 
<div>
    <Routes >
        ......
        ......
    </Routes>
 </div>

//V5版本 
import {Route, Switch} from 'react-router-dom';
 
<div>
    <Switch>
        <Route exact  path="/">
            <Home />
        </Route>
    </Switch>
 </div>
//V6的版本
import {Route, Routes } from 'react-router-dom';
 
<div>
    <Routes >
        <Route path="/" element={<Home />} />
    </Routes>
 
 </div>

//路由配置中
//V5代码如下
import { Redirect } from 'react-router-dom';
<Redirect to="/home" />
//V6如下
import { Navigate } from 'react-router-dom';
<Route path="/" element ={<Navigate replace to="/home" />} />

//组件内部
//V5版本
import { Redirect } from 'react-router-dom';
//重定向到首页
return <Redirect to="/" />

//V6版本
import { Navigate } from 'react-router-dom';
//重定向到首页
return <Navigate to="/" />

import {useNavigate} from 'react-router-dom';
const navigate = useNavigate();
//如去首页
navigate("/home");
//还可使用
navigate(-1);  //后退到前一页
navigate(-2); //后退到前两页的前一页， 
navigate(1); //前向导航 等等依此类推

//路由中
<Routes>
  <Route path='/user/*'  element={<User />} 
   	    <Route path='user-item' element={<div>我是嵌套子项</div>} />
  <Route/>
</Routes>

//User组件中
import {Outlet} from 'react-router-dom';
const User = () => {
	return 
	<section>
	  <h1>我是外容器</h1>
	  <Outlet />
	</section>
