使用react-router-dom时如何在React中路由公用文件夹请求

npm install react-router-dom

import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Home from './Home';
import About from './About';
import Contact from './Contact';

const RouterComponent = () => {
  return (
    <Router>
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
        <Route path="/contact" component={Contact} />
      </Switch>
    </Router>
  );
};

export default RouterComponent;

import React, { useEffect, useState } from 'react';

const Home = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    // 发起请求并更新数据
    fetch('/api/data')
      .then(response => response.json())
      .then(data => setData(data));
  }, []);

  return (
    <div>
      <h1>Home</h1>
      <ul>
        {data.map(item => (
          <li key={item.id}>{item.name}</li>
        ))}
      </ul>
    </div>
  );
};

export default Home;

import React from 'react';
import RouterComponent from './公用文件夹/RouterComponent';

const App = () => {
  return (
    <div>
      <h1>My App</h1>
      <RouterComponent />
    </div>
  );
};

export default App;
