reactjs - 使用react的 session 超时警告模式

Question

如果用户不采取任何行动，我需要在 13 分钟不活动后显示超时警告模式，并在 15 分钟后结束 session 。我需要使用reactjs 来实现这一点。我在 https://www.npmjs.com/package/react-timeout#react-classic-verbose 检查了 react 超时，但这没有帮助。如果有人知道如何做到这一点，请与我分享。

您可以像这样创建一个高阶组件，并可以通过高阶组件传递子组件

HOC:

`//代码

export default function(ComposedClass) {
  class AutoLogout extends React.Component {
    constructor(props) {
      super(props);
      this.state = {
        warningTime: 1000 * 60 * 10,
        signoutTime: 1000 * 60 * 15,
      };
    }

    componentDidMount() {
      this.events = [
        'load',
        'mousemove',
        'mousedown',
        'click',
        'scroll',
        'keypress'
      ];

      for (var i in this.events) {
        window.addEventListener(this.events[i], this.resetTimeout);
      }

      this.setTimeout();
    }

    clearTimeoutFunc = () => {
      if (this.warnTimeout) clearTimeout(this.warnTimeout);

      if (this.logoutTimeout) clearTimeout(this.logoutTimeout);
    };

    setTimeout = () => {
      this.warnTimeout = setTimeout(this.warn, this.state.warningTime);
      this.logoutTimeout = setTimeout(this.logout, this.state.signoutTime);
    };

    resetTimeout = () => {
      this.clearTimeoutFunc();
      this.setTimeout();
    };

    warn = () => {
      window.alert("You will be logged out automatically in 1 minute")
      console.log('You will be logged out automatically in 1 minute.');
    };

    logout = () => {
      // Send a logout request to the API
      console.log('Sending a logout request to the API...');
      this.destroy();
    };

    destroy = () => {
     //clear the session
      browserHistory.push('/');
      window.location.assign('/');
    };

    render() {

      return (
        <div>
          <ComposedClass {...this.props} />
        </div>
      );
    }
  }
}

`

您可以将此 HOC 包装到路由文件中由于不活动而向用户发出警告的所有组件

<Route path="/test" component={HOC(comonent)} />

上面的代码组件将是您要添加此功能的页面。
