javascript - REACT 中的 404 页面

Question

我创建了组件 NotFound当我转到一个不存在的页面时它工作正常。但是同一个页面出现在我的所有页面中，而不仅仅是不存在的页面。这是组件:

import React from 'react'

const NotFound = () =>
  <div>
    <h3>404 page not found</h3>
    <p>We are sorry but the page you are looking for does not exist.</p>
  </div>

export default NotFound

这就是我在主页中使用它的方式:

class MainSite extends Component {
  render () {
    return (
      <div>
        {/* Render nav */}
        <Route path='/dashboard' component={Nav} />
        <Route path='/retrospectives' component={Nav} />
        <Route path='/users' component={Nav} />
        <Route path='/projects' component={Nav} />

        {/* Dashboard page */}
        <ProtectedRoute exact path='/dashboard' component={DashboardPage} />

        {/* Retrospectives page */}
        <ProtectedRoute exact path='/retrospectives' component={RetrospectivesPage} />

        {/* Users page */}
        <ProtectedRoute exact path='/users' component={UsersPage} />

        {/* Projects page */}
        <ProtectedRoute exact path='/projects' component={ProjectsPage} />

        {/* Retrospective related pages */}
        <Route exact path='/retrospectives/:retrospectiveId' component={Retrospective} />
        <Route exact path='/join-retrospective' component={JoinRetrospective} />
        <ProtectedRoute exact path='/create-retrospective/:retrospectiveId' component={Retrospective} />

        {/* OnBoarding pages */}
        <ProtectedRoute exact path='/beta-code' component={BetaCodeAccess} />
        <Route exact path='/auth-handler' component={AuthHandler} />
        <Route exact path='/join-organization' component={JoinOrganization} />
      </div>
    )
  }
}

export default MainSite

如你所见，我使用 <Route path="*" component={NotFound} />创建 404 页面，但该组件也出现在每个现有页面中。我该如何解决这个问题？

试试这个:

  import { Switch, Route } from 'react-router-dom';

  <Switch>
    <Route path='/dashboard' component={Nav} />
    <Route path='/retrospectives' component={Nav} />
    <Route path='/users' component={Nav} />
    <Route path='/projects' component={Nav} />

    <Route path="" component={NotFound} />
  </Switch>
