1，vue-router

vue 的路由配置文件，

// src/router/index.ts
const routes = [
    {
        path: "/news",
        children: [
            { path: "", component: NewsView },
            { path: "detail", component: NewsDetail },
            { path: "search", component: NewsSearch },
        ],
    },
    {
        path: "/goods",
        component: GoodsView,
        children: [
            { path: "detail", component: GoodsDetail },
            { path: "search", component: GoodsSearch },
        ],
    },
    { path: "/", component: HomeView },
];

在 App.vue 中使用 RouterView 即可渲染匹配到的路由：

<template>
    <RouterView></RouterView>
</template>

另外，注意 news 和 goods 路由的区别：

• news 相关的3个路由页面是相互独立的，只是逻辑上有关系。
• goods 路由的写法，需要在 GoodsView 组件内也使用 RouterView 才能访问到路由 goods/detail 和 goods/search 对应的页面。

<template>
	<div>goods主页面</div>
    <RouterView></RouterView>
</template>

2，React 模拟实现

使用和 vue 相同的配置文件，routeConfig.js

App.jsx

import { BrowserRouter as Router, Switch, Link } from "react-router-dom";
import RootRoute from "./RootRoute";

export default function App() {
    return (
        <Router>
            <Link to="/">首页</Link>
            <Link to="/news">新闻页</Link>
            <Link to="/goods">商品页</Link>
            <Switch>
                <RootRoute></RootRoute>
            </Switch>
        </Router>
    );
}

关键实现：RootRoute.js

import React from "react";
import { Route } from "react-router-dom";
import routeConfig from "./routeConfig";

export default function RootRoute() {
    return getRoutes(routeConfig, "");
}

function getRoutes(routes, basePath) {
    if (!Array.isArray(routes)) {
        return null;
    }
    return routes.map((route) => {
        const { path, component: Component, children, ...rest } = route;
        const newPath = `${basePath}${path}`;
        // 适配 news 路由的方式
        if (Component) {
            return (
                <Route
                    key={newPath}
                    path={newPath}
                    exact={["", "/"].includes(path)}
                    {...rest}
                    render={(values) => {
                        return <Component {...values}>{getRoutes(children, newPath)}</Component>;
                    }}
                ></Route>
            );
        } else {
            return getRoutes(children, newPath);
        }
    });
}

News.jsx

export default function News() {
    return (
        <div>
            <div>News页面</div>
            <Link to="/news/detail">详情</Link>
            <Link to="/news/search">查询</Link>
        </div>
    );
}

Goods.jsx，其中 props.children 是 RootRoute.js 遍历子路由渲染出对应的 <Route> 组件。

export default function Goods(props) {
    return (
        <div>
            <div>Goods页面</div>
            <Link to="/goods/detail">goods详情</Link>
            <Link to="/goods/search">goods查询</Link>
            <div>{props.children}</div>
        </div>
    );
}

效果：
