How to set the DefaultRoute to another Route in Re

问题:

I have the following:

  <Route name="app" path="/" handler={App}>
    <Route name="dashboards" path="dashboards" handler={Dashboard}>
      <Route name="exploreDashboard" path="exploreDashboard" handler={ExploreDashboard} />
      <Route name="searchDashboard" path="searchDashboard" handler={SearchDashboard} />
      <DefaultRoute handler={DashboardExplain} />
    </Route>
    <DefaultRoute handler={SearchDashboard} />
  </Route>

When using the DefaultRoute, SearchDashboard renders incorrectly since any *Dashboard needs to rendered within Dashboard.

I would like for my DefaultRoute within the "app" Route to point to the Route "searchDashboard". Is this something that I can do with React Router, or should I use normal Javascript (for a page redirect) for this?

Basically, if the user goes to the home page I want to send them instead to the search dashboard. So I guess I'm looking for a React Router feature equivalent to window.location.replace("mygreathostname.com/#/dashboards/searchDashboard");

回答1:

You can use Redirect instead of DefaultRoute

<Redirect from="/" to="searchDashboard" />

Update 2019-08-09 to avoid problem with refresh use this instead, thanks to Ogglas

<Redirect exact from="/" to="searchDashboard" />

The problem with using <Redirect from="/" to="searchDashboard" /> is if you have a different URL, say /indexDashboard and the user hits refresh or gets a URL sent to them, the user will be redirected to /searchDashboard anyway.

If you wan't users to be able to refresh the site or send URLs use this:

<Route exact path="/" render={() => (
    <Redirect to="/searchDashboard"/>
)}/>

Use this if searchDashboard is behind login:

<Route exact path="/" render={() => (
  loggedIn ? (
    <Redirect to="/searchDashboard"/>
  ) : (
    <Redirect to="/login"/>
  )
)}/>

I was incorrectly trying to create a default path with:

<IndexRoute component={DefaultComponent} />
<Route path="/default-path" component={DefaultComponent} />

But this creates two different paths that render the same component. Not only is this pointless, but it can cause glitches in your UI, i.e., when you are styling <Link/> elements based on this.history.isActive().

The right way to create a default route (that is not the index route) is to use <IndexRedirect/>:

<IndexRedirect to="/default-path" />
<Route path="/default-path" component={DefaultComponent} />

This is based on react-router 1.0.0. See https://github.com/rackt/react-router/blob/master/modules/IndexRedirect.js.

Jonathan's answer didn't seem to work for me. I'm using React v0.14.0 and React Router v1.0.0-rc3. This did:

<IndexRoute component={Home}/>.

So in Matthew's Case, I believe he'd want:

<IndexRoute component={SearchDashboard}/>.

import { Route, Redirect } from "react-router-dom";

class App extends Component {
  render() {
    return (
      <div>
        <Route path='/'>
          <Redirect to="/something" />
        </Route>
//rest of code here

this will make it so that when you load up the server on local host it will re direct you to /something

 <Route name="app" path="/" handler={App}>
    <Route name="dashboards" path="dashboards" handler={Dashboard}>
      <Route name="exploreDashboard" path="exploreDashboard" handler={ExploreDashboard} />
      <Route name="searchDashboard" path="searchDashboard" handler={SearchDashboard} />
      <DefaultRoute handler={DashboardExplain} />
    </Route>
    <Redirect from="/*" to="/" />
  </Route>

I ran into a similar issue; I wanted a default route handler if none of the route handler matched.

My solutions is to use a wildcard as the path value. ie Also make sure it is the last entry in your routes definition.

<Route path="/" component={App} >
    <IndexRoute component={HomePage} />
    <Route path="about" component={AboutPage} />
    <Route path="home" component={HomePage} />
    <Route path="*" component={HomePage} />
</Route>

For those coming into 2017, this is the new solution with IndexRedirect:

<Route path="/" component={App}>
  <IndexRedirect to="/welcome" />
  <Route path="welcome" component={Welcome} />
  <Route path="about" component={About} />
</Route>

The preferred method is to use the react router IndexRoutes component

You use it like this (taken from the react router docs linked above):

<Route path="/" component={App}>
    <IndexRedirect to="/welcome" />
    <Route path="welcome" component={Welcome} />
    <Route path="about" component={About} />
</Route>
