react如何去创建路由呢？

Posted 2022-05-09 fengshaopu

首先下载react路由版本

npm i react-router-dom@5.2.0

然后去创建页面跟管理路由的文件夹

然后可以去router文件里面去创建

import React,  Component  from 'react' //导入react
import  Route  from 'react-router-dom' 
import Home from '../Home/index'  //导入路由
import About from '../Adome/index'


export default class index extends Component
     render()
          return(
               <div>
                  <Route path="/" component=Home></Route>
                  <Route path="/adome" component=About></Route>
               </div>
          )
     

随后在index.js里面导入并且包裹App

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';

import  BrowserRouter  from 'react-router-dom'


const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>
);

// If you want to start measuring performance in your app, pass a function
// to log results (for example: reportWebVitals(console.log))
// or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals
reportWebVitals();

最后在app.js中导入router

// import logo from './logo.svg';
import './App.css';
import  Index  from './router/index'

function App() 
  return (
    // <div className="App">
    //   <header className="App-header">
    //     <img src=logo className="App-logo" alt="logo" />
    //     <p>
    //       Edit <code>src/App.js</code> and save to reload.
    //     </p>
    //     <a  className="App-link" href="https://reactjs.org" target="_blank"  rel="noopener noreferrer"  >
    //       Learn React
    //     </a>
    //   </header>
    // </div>
    <div className="App">
       <Index></Index>
    </div>
  );


export default App;
