重定向willTransitionTo在react-router 2.4.0中?

Rag*_*san 5 reactjs react-router

我目前正在使用"react-router": "^2.4.0"我的聊天应用程序,并且在没有用户时如何重定向感到困惑.我不认为重定向的作品"^2.4.0".

我应该onEnter聊天路径上使用挂钩吗?

像这样的东西:

 <Route path="chat" component={Chat} onEnter={Chat.willTransitionTo}/>

 <Route path="/" component={App} >
    <IndexRoute component={Chat} />

我通过使用它使其工作,setRouteLeaveHook如下所示: https: //github.com/ReactTraining/react-router/blob/master/docs/guides/ConfirmingNavigation.md

返回 false 以防止不提示用户的转换

但是,他们忘记提及该钩子也应该取消注册,请参阅此处此处

我们可以使用它来实现我们自己的解决方案,如下所示:

class YourComponent extends Component {
  constructor() {
    super();

    const {route} = this.props;
    const {router} = this.context;

    this.unregisterLeaveHook = router.setRouteLeaveHook(
      route,
      this.routerWillLeave.bind(this)
    );
  }

  componentWillUnmount() {
    this.unregisterLeaveHook();
  }

  routerWillLeave() {
    // return false to prevent a transition w/o prompting the user,
    // or return a string to allow the user to decide:
    if (!this.state.isSaved) {
      return 'Your work is not saved! Are you sure you want to leave?'
    }
  }
  ...
}

YourComponent.contextTypes = {
  router: routerShape
};
