使用 React^16.13.1和 react-router-dom ^5.2.0，我們有多個導航文件來進行嵌套導航，第一個Navigation.js可以正常運行和重定向，但第二個Navigation.js不能按我們預期的那樣工作。使用創建了一個反應APPnpx create-react-app nested列出重要文件以供審查：應用程序.jsimport React from 'react';import logo from './logo.svg';import './App.css';import Navigation from "./Navigation";import { BrowserRouter } from "react-router-dom";const App = () => {  return (    <BrowserRouter>      <Navigation />    </BrowserRouter>  );};export default App;導航.jsimport React from "react";import { Switch, Route, BrowserRouter } from "react-router-dom";import nestedNavigation from "./nested/Navigation";const NotFound = () => <h1>Not Found</h1>;const Navigation = () => {  return (      <Switch>        <Route exact path="/welcome" component={nestedNavigation} />        <Route path="/" component={NotFound} />      </Switch>  );};export default Navigation;nested/Navigation.js嵌套導航-第二個import React from "react";import {  Switch,  Route,  BrowserRouter,  useRouteMatch,} from "react-router-dom";import Welcome from "../Welcome"const Navigation = () => {    let { path, url } = useRouteMatch();    debugger;    return (        <Switch>            <Route path={`${path}/nested`} exact component={Welcome} />        </Switch>    );}export default Navigation;
