react我自己还在摸索学习中，今天正好学习一下react-router4 嵌套路由的使用方法，顺便留着笔记
先直接贴代码
import React from 'react';
import ReactDOM from 'react-dom';
import { HashRouter as Router, Route, Switch} from 'react-router-dom';
import createBrowserHistory from 'history/createBrowserHistory';
import UserAddPage from './pages/UserAdd/index';
import HomePage from './pages/Home/index';
import HomeLayout from './components/HomeLayout/index';
const hashHistory = createBrowserHistory();
const NoMatch = ({ location }) => (
<div>
<h3>无法匹配 <code>{location.pathname}</code></h3>
</div>
)
ReactDOM.render((
<Router history={hashHistory}>
<div>
<HomeLayout>//总会加载这个组件，并且下面 swicth 里面的组件会在它里面 render
<Switch>
<Route path="/" exact component={HomePage}/>
<Route path="/user/add" component={UserAddPage}/>
<Route component={NoMatch}/>
</Switch>
</HomeLayout>
</div>
</Router>
), document.getElementById('root'));
