React router:I don't want user to directly navigate to pages by typing urls but allow going to pages only using links inside the app.

问题

My Routes.js

<Route path="/game-center" component={GameCenter} />
      <Route path="/game-center/pickAndWin" component={PickAndWin} />
      <Route path="/game-center/memory" component={Memory} />
      <Route path="/game-center/summary" component={GameSummary} />
    </Route>
  </Router>

On Card Click i'm routing him to the game or summary depending whther game is live or expired.

cardClick=(type, name, status, gameId) => {
    console.log(`here${type}${status}`, name);
    this.props.dispatch(GameCenterActions.setShowGame());
    if (status === LIVE) {
      this.props.dispatch(GameCenterActions.selectGame({ type, name, status, gameId }));
      this.props.dispatch(GameCenterActions.resetShowSummary());
      hashHistory.push(LIVE_GAMES[type]);
    } else if (status === EXPIRED) {
      this.props.dispatch(GameCenterActions.setShowSummary());
      console.log(`${EXPIRED_GAMES}summary page here`);
      this.props.dispatch(GameCenterActions.selectGame({ type, name, status, gameId }));
      hashHistory.push('/game-center/summary');
    }
  }

When user directly types url '/game-center/summary' he should not be allowed and should be sent back to home page. Is this possible in react router itself? I want to implement this in my entire app. I don't want user to directly navigate to pages by typing urls but going to pages only using links inside the app.

You can do this by using Higher Order Components. Such as you can set a flag when user is authenticated and then attach this HOC with the specified component in react router

import React,{Component} from 'react';
import {connect} from 'react-redux';
export default function(ComposedComponent){
  class Authentication extends Component{
    static contextTypes = {
      router : React.PropTypes.object
    }
    componentWillMount(){
      if(!this.props.user){
        this.context.router.push('/');
      }
    }
    componentWillUpdate(nextProps){
      if(!nextProps.user){
          this.context.router.push('/');
      }
    }
    render(){
      return(<ComposedComponent {...this.props}/>);
    }
  } 
}

And then in your routes

  <Route path="home" component={requireAuth(Home)}></Route>
