跟组件
/*
react路由的配置：
1、找到官方文档 https://reacttraining.com/react-router/web/example/basic
2、安装 cnpm install react-router-dom --save
3、找到项目的根组件引入react-router-dom
import { BrowserRouter as Router, Route, Link } from "react-router-dom";
4、复制官网文档根组件里面的内容进行修改 （加载的组件要提前引入）
<Router>
<Link to="/">首页</Link>
<Link to="/news">新闻</Link>
<Link to="/product">商品</Link>
<Route exact path="/" component={Home} />
<Route path="/news" component={News} />
<Route path="/product" component={Product} />
</Router>
