javascript - 子页面与react-router 4不匹配

Question

我的路由器设置是这样的

<Switch>
  <PrivatePage key={index} {...opts} component={(props) => 
     <Section {...props} pages={childRoutes} />
  } />
  <PrivatePage path='/accounts/:id' exact={true}  render={({ match }) => (
    <Redirect to={/accounts/${match.params.id}/profile} />
  )} />
  ...
  <Route component={NotFound} />
</Switch>

然后<Section />

<SubNavMenu />
<Route path=/accounts/:id/profile componet={ProfilePage} />
<Route path=/accounts/:id/dashboard componet={DashboardPage} />

然后<PrivatePage />呈现类似，而 <Page />只是渲染<Navigation /> {this.props.children}

const PrivatePage = ({ component: Component, ...rest }) => {
  let result = props => (
    <Redirect
      to={{
        pathname: '/redirect',
        state: { from: props.location },
      }}
    />
  )

  if (User.methods.isAuthed()) {
    result = props => (
      <Page>
        <Component {...props} />
      </Page>
    )
  } else if (rest.path === '/') {
    result = props => (
      <Redirect
        to={{
          pathname: '/login',
        }}
      />
    )
  }

  return <Route {...rest} render={props => result(props)} />
}

export default PrivatePage

单击一个链接，将我带到 accounts/:id正确地将我重定向到个人资料页面，但是当我尝试从 SubNavMenu 转到仪表板页面时，我得到了 NotFound 页面并安慰 this.props.match {path: "/", url: "/", params: {…}, isExact: false}但我的路径是/accounts/7kB7fRdsu39Be44ou/dashboard

感谢您的帮助

<Button />的渲染方法(由 <Menu /> 包裹

 render() {
    const {
      activeClass,
      containerClass,
      exactLink,
      hoverClass,

          <div className='Button--messageIcon'><Icon name={icon} / ></div>
          <div className='Button--messageText'>{label}</div>
        </div>
      )    
    }

    const buttonContainerClass = this.isHovering() ? `${containerClass} ${hoverClass}` : containerClass

    const ButtonContainer = props => (
      <button
        {...props}

    let Result
    if (typeof(link) === 'string') {

    return Result
  }

我遇到了类似的问题，Switch 找不到用其他组件包装的路由。查看源代码，看起来 Switch 并没有在子级中递归地查找 Route，因此它们不能嵌套。

既然如此，要使用 Switch，您需要重构以使 Route 成为每个路由的顶级组件。或者重构为不使用 Switch - 基本上使所有路由完全匹配。

切换来源:https://github.com/ReactTraining/react-router/blob/master/packages/react-router/modules/Switch.js它使用 React.Children.forEach 来查找路径，该路径仅迭代直接子项，而不是嵌套子项。
