关于react.js:react配置路由

1.开发环境 react
2.电脑系统 windows10专业版
3.在应用react开发的过程中,咱们发现react官网没有路由,而后去网上搜寻,给出了两个罕用的react-router和react-router-dom,上面我来分享一下。
4.react-router和react-router-dom有什么区别?

置信很多小伙伴们刚开始的都会和我一样,在应用react来创立路由的时候,写的是:
import *** from 'react-router';

而后百度了很多博客,发现是:
import *** from 'react-router-dom';

4-1.那么react-router和react-router-dom有什么关系呢?

react-router:提供了router的外围api,如Router/Route/Switch等,但没有提供无关dom操作进行路由跳转api;
react-router-dom:提供了BrowserRouter/Route/Link等api,能够通过dom操作触发事件管制路由
那么咱们要怎么用呢?
首先,react-router-dom里蕴含了react-router的依赖,因而咱们在装置的时候只须要装置后者即可。

npm i react-router-dom -S

4-2.根底应用

//引入react jsx写法的必须
import React from 'react'; 
//引入须要用到的页面组件 
import Home from './pages/home';
import About from './pages/about';
//引入一些模块
import { BrowserRouter as Router, Route} from "react-router-dom";

function router(){
return (
<Router>
    <Route path="/home" component={Home} />
    <Route path="/about" component={About} />
</Router>);
}

export default router;

//home.js
import React, { Component } from 'react';

export default class Home extends Component {
  render() {
    return (<h1>
      欢送,这里是Home
    </h1>)
  }
}

//about.js
import React, { Component } from 'react';

export default class About extends Component {
  render() {
    return (<h1>
      欢送,这里是About
    </h1>)
  }
}

//在app.js中引入
import Router from './Router'
class App extends React.Component {
render(){
return (
  <Router />
);
}
}

5.重定向

//router.js
//须要import一下Redirect
import {Redirect} from "react-router-dom";

return (
<Router>
    <Route path="/home" component={Home} />
    <Route path="/" render={
      ()=> (
      <Redirect to="/home"/>)}>
    </Route>
</Router>);
}
export default router;

6.路由嵌套

import React from 'react';
import './App.css';
import './assets/font/iconfont.css'
import {  BrowserRouter, Route,Switch,Redirect } from "react-router-dom"
import Home from './views/Home';
import TextView from './views/TextView';
import TextView from './views/Next';
class App extends React.Component{
  render() {
    return (
        <BrowserRouter>
            <Switch>
                <Redirect exact from='/' to='/Home'></Redirect>
                  <Home exact path='/Home'>
                      <Redirect exact from='/Home' to="/Home/TextView" />
                      <Route exact  path='/Home/TextView' component={TextView}></Route>
                      <Route exact  path='/Home/Next' component={Next}></Route>
                  </Home>
                  
              </Switch>
        </BrowserRouter>
    )
  }
}
