1.? 下载插件 yarn add react-router-dom --save / npm i react-router-dom --save 2.? 配置基础路由 import { BrowserRouter,Route,Link } from ‘react-router-dom‘
<Provider>
<BrowserRouter>
<div>
<ul>
<li>
<Link to="/">一营</Link>
</li>
<li>
<Link to="/Erying">二营</Link>
</li>
<li>
<Link to="/Qibing">骑兵连</Link>
</li>
</ul>
// exact用来精准匹配路由
<Route path="/" exact component={App} />
<Route path="/Erying" component={Erying} />
<Route path="/Qibing" component={Qibing} />
</div>
</BrowserRouter>
</Provider>
3.? 重导向(Redirect) import { Redirect } from ‘react-router-dom‘
<Redirect to="/somePath" ></Redirect> // 每次页面加载首先进这个地址
4. Switch匹配 import { Switch } from ‘react-router-dom‘
<Switch>
<Route path="/" exact component={App} />
<Route path="/Erying" component={Erying} />
<Route path="/Qibing" component={Qibing} />
<Route component={NoMatch} /> // 没有匹配到任何地址, 404的情况
</Switch>
5.? 子路由嵌套 <Route path="/" render={() =>
<Admin>
<Switch>
<Route path="/home" component={ Home } />
<Route path="/ui/buttons" component={ Buttons }></Route>
<Route path="/form/login" component={ FormLogin }></Route>
<Route path="/charts/line" component={ ChartLine }></Route>
<Route path="/permission" component={ PermissionIndex }></Route>
<Redirect to="/home" />
<Route component={ NoMatch } />
</Switch>
</Admin>
}/>
