做一個網(wǎng)站，header和footer固定，中間內容通過路由匹配，
代碼如下：
class App extends React.Component {

render() {

return (
  <div>
    <BackTop />
    <Layout className="layout">
      <Header className="header">
        <Headerc></Headerc>
      </Header>
      <Content className="content">
        <Switch>
          <Route
                 exact
                 path="/"
                 component={ Home } />
          <Route
                 path="/lab"
                 component={ Laboratory } />
          <Route
                 path="/hardware"
                 component={ Hardware } />
          <Route
                 path="/agricultural"
                 component={ Agricultural } />
          <Route
                 path="/service"
                 component={ Service } />
          <Route
                 exact
                 path="/diseases"
                 component={ Diseases } />
          <Route
                 path="/diseases/diseasesDetail/:id?"
                 component={ DiseasesDetail } />
          <Route
                 path="/aboutus"
                 component={ AboutUS } />
          <Route component={ Error } />
        </Switch>
      </Content>
      <Footer className="footer">
        <Footerc></Footerc>
      </Footer>
    </Layout>
  </div>
);

}
}

export default App;

現(xiàn)在的問題是，我切換導航菜單，路由可以正常切換，但是點擊瀏覽器的返回鍵，路由切換了，導航欄菜單高亮沒有改變，請問這個如何解決？
