我想用来basename分离组件。我也有全局 url，所以我最终使用了 3BrowserRouter秒。这会导致显示多个内容。如果我去/fruit/search，它会同时显示Homepage组件和FruitSearch组件的内容。我究竟如何使用多个BrowserRouters？

class App extends Component {
    render() {
        return (
            <div>
                <Header/>
                <BrowserRouter basename='/vegetable'>
                    <Switch>
                        <Route exact path='/search' component={VegetableSearch}/>
                        <Route exact path='/contact/:sellerId' component={ContactSeller}/>
                    </Switch>
                </BrowserRouter>
                <BrowserRouter basename='/fruit'>
                    <Switch>
                        <Route exact path='/search' component={FruitSearch}/>
                        <Route exact path='/contact/:sellerId' component={ContactSeller}/>
                    </Switch>
                </BrowserRouter>
                <BrowserRouter>
                    <div>
                        <Route path='/login' component={Login}/>
                        <Route path='/register' component={Registration}/>
                        <Route path='/about' component={AboutUs}/>
                        <Route path='/faq' component={Faq}/>
                        <Route path='/' component={Homepage}/>
                    </div>
                </BrowserRouter>
                <Footer/>
            </div>
        );
    }
}

export default App;
