React Router 中嵌套路由中的默认组件

Question

在 React Router 中我有一个嵌套路由

<Route path='about' component={{main: About, header: Header}}>
  <Route path='team' component={Team} />
</Route>

所以现在当我转到 /about/team 时它会显示团队。

但是如何设置访问/about时看到哪个组件呢？

我试过了

<Route path='about' component={{main: About, header: Header}}>
  <IndexRoute component={AboutIndex} />
  <Route path='team' component={Team} />
</Route>

和

<Route path='about' component={{main: About, header: Header}}>
  <Route path='/' component={AboutIndex} />
  <Route path='team' component={Team} />
</Route>

但它不起作用。

我的 About 组件如下所示

class About extends React.Component {
  render () {
    return (
      <div>
        <div className='row'>
          <div className='col-md-9'>
            {this.props.children}
          </div>
          <div className='col-md-3'>
            <ul className='nav nav-pills nav-stacked'>
              <li className='nav-item'><IndexLink className='nav-link' to='/about' activeClassName='active'>About</IndexLink></li>
              <li className='nav-item'><Link className='nav-link' to='/about/team'>Team</Link></li>
            </ul>
          </div>
        </div>
      </div>
    );
  }
}

反应路由器 4 更新

默认路由是没有路径的。

import BrowserRouter from 'react-router-dom/BrowserRouter';
import Switch from 'react-router-dom/Switch';
import Route from 'react-router-dom/Route';

<BrowserRouter>
  <Switch>
    <Route exact path='/about' component={AboutIndex} />
    <Route component={AboutIndex} /> // <--- don't add a path for a default route
  </Switch>
</BrowserRouter>

如果您的组件中不需要此对象{main: About, header: Header}，则只需将 AboutIndex 放在组件属性中。应该可以的

<Router history={browserHistory}>
  <Route path='about' component={AboutIndex}>
    <IndexRoute component={AboutIndex} />
    <Route path='team' component={Team} />
  </Route>
</Router>

如果您仍然需要主组件和标题组件，只需根据您的需要将它们添加为父组件、子组件或兄弟组件
