Push to React Router History from Parent Component

问题

I want to control the router component <HashRouter></HashRouter> from my application's root level <App> </App>component (which contains the router as a child).

class App extends Component {
    componentDidMount(){
       // potentially push to history here
    }
    render () {
        <HashRouter></HashRouter>
    }
}

Is this possible? (Using react-router-dom at 4.2.2)

回答1:

Non-route component can use withRouter (it's actually a wrapper for <Route children>) in order to get access to router-specific props, particularly history.

withRouter component should reside inside router so it cannot be applied to App. potentially push to history here task should be delegated to <Router> child component enhanced with withRouter:

@withRouter
class Child extends Component {
  componentDidMount() {
    this.props.history.push(...);
  }
  render () {
    return null;
  }
}
