First, the modular route (route defined by the dictionary, and then rotated out)

App.js
import React from 'react';
import './App.css';
import { BrowserRouter as Router, Route,Link } from 'react-router-dom'; //引入路由模块
import Home from './components/home';
import User from './components/user';
//【1】定义一个数组，里面存放route的字典
let routes=[
{
path:'/',
exact:true,
component:Home
},
{
path:'/user/',
component:User
}
]
function App() {
return (
<Router>
<div>
<header className='header'>
<Link to='/'>首页</Link>
<Link to='user'>个人中心</Link>
</header>
{/* 【2】循环出来刚定义的数组内字典——模块块完成。注意此处的routes直接.map即可，不要加this了因为它就定义在页面上 */}
{
routes.map((v,k)=>{
if(v.exact){
return <Route exact path={v.path} component={v.component} />
}else{
return <Route path={v.path} component={v.component} />
}
})
}
</div>
</Router>
);
}
export default App;3. The modular routing: Further, the routing into a single file
The first step should first be drawn route definition: /src/model/routes.js
import Home from '../components/home';
import User from '../components/user';
//【1】定义一个数组，里面存放route的字典
let routes=[
{
path:'/',
exact:true,
component:Home
},
{
path:'/user/',
component:User
}
]
export default routes;The second step, introducing routes.js to /src/App.js
import React from 'react';
import './App.css';
import { BrowserRouter as Router, Route,Link } from 'react-router-dom'; //引入路由模块
import routes from './model/routes.js';
function App() {
return (
<Router>
<div>
<header className='header'>
<Link to='/'>首页</Link>
<Link to='user'>个人中心</Link>
</header>
{/* 【2】循环出来刚定义的数组内字典——模块块完成。注意此处的routes直接.map即可，不要加this了因为它就定义在页面上 */}
{
routes.map((v,k)=>{
if(v.exact){
return <Route exact path={v.path} component={v.component} />
}else{
return <Route path={v.path} component={v.component} />
}
})
}
</div>
</Router>
);
}
export default App;Ibid effect
Two nested components pass route Sons value
Function: root component of the routing, routing User swapped out components on separate /model/router.js in as a file, its internal routing roots contain components, sub-assemblies and routing of User.js. No matter which configuration after routing components are configured to go into here.

<div>
<header className="title">
<Link to="/">首页组件</Link>
<Link to="/user">用户页面</Link>
<Link to="/shop">商户</Link>
<Link to="/news">新闻</Link>
</header>
{
routes.map((route,key)=>{
if(route.exact){
return <Route key={key} exact path={route.path}
// route.component value.component <User {...props} routes={route.routes} />
render={props => (
// pass the sub-routes down to keep nesting
<route.component {...props} routes={route.routes} />
)}
/>
}else{
