React-router路由配置及跳转

1、V6对比V5的修改内容

1、API: useNavigate 代替了useHistory 。
2、废弃了Route组件的exact属性。
3、组件 <Routes>代替了<Switch>
4、组件NavLink中移除了 activeStyle activeClassName 属性。

2、安装依赖react-router-dom

npm install react-router-dom -S

3、创建文件配置router.jsx

import { Route } from 'react-router-dom';
import Login from '@views/login/Index.jsx';
import Settings from '@views/settings/Index.jsx';// 定义路由配置数组
const routes = [{path: '/',component: Login,},{path: '/login',component: Login,},{path: '/settings',component: Settings,},
];// 将路由配置数组转换为Route组件(注意：Component属性是大写开头)
const renderRoutes = () => routes.map((route, index) => (<Routekey={index}path={route.path}Component={route.component}/>
));export default renderRoutes;

4、在APP.jsx文件中引入并使用

import renderRoutes from '@router/index.jsx';
import{HashRouter, Routes,Route,Router}from"react-router-dom";
function App() {return (<div><HashRouter><Routes>{renderRoutes()}</Routes></HashRouter></div>)
}export default App;

如果不单独配置router.jsx的话，也可以在APP.jsx中直接写

import Login from './views/login/Index.jsx';
import Settings from './views/settings/Index.jsx';
import{HashRouter, Routes,Route,Router}from"react-router-dom"
function App() {return (<div><HashRouter><Routes><Route path="/" Component={Login}></Route><Route path="/settings" Component={Settings}></Route></Routes></HashRouter></div>)
}export default App;

5、路由跳转

举例：在登录页面，点击

import { useNavigate } from "react-router-dom";
const Login = () => {const Navigate = useNavigate();const goSettings = () => {Navigate('/settings');};return (<div><button onClick={goSettings}>跳转到设置页面</button></div>)
};
export default Login;

注意

1、Route组件的常用属性有以下：
path：与URL匹配的路径
children：嵌套的路由配置
element/Component: 元素/组件
lazy：返回一个动态的组件引入。
2、Route中没有属性name
