使用BrowserRouter

我正在尝试使用React Idle Timer在15分钟后进入锁定屏幕。

我遇到的问题是重定向页面。我正在使用带有react和react BrowserRouter的电子。因此,我不能使用window.location.assign('/ clock'); (或类似的window.location)方法来重定向页面。通常在我的组件中使用:

this.props.history.push("/clock");

这在BrowserRouter的Switch内的组件中起作用。但是,我需要React Idle Timer处于最高级别,并且当我在 onIdle 函数中使用props.history.push时,会收到以下消息:

Uncaught TypeError: Cannot read property 'push' of undefined

class AppRouter extends Component {
  constructor(props) {
    super(props);
    this.idleTimer = null;
    this.onAction = this._onAction.bind(this);
    this.onActive = this._onActive.bind(this);
    this.onIdle = this._onIdle.bind(this);
  }

  _onAction(e) {
    console.log("user did something", e);
  }

  _onActive(e) {
    console.log("user is active", e);
    console.log("time remaining", this.idleTimer.getRemainingTime());
  }

  _onIdle(e) {
    console.log("user is idle", e);
    console.log("last active", this.idleTimer.getLastActiveTime());

//need to push to  /clock after 15 minutes
//window.location.assign('/clock');  -- WORKS in browser, but not with Electron

// this.props.history.push("/clock"); -- gives Uncaught TypeError: Cannot read property 'push' of undefined

//can't place <IdleTimer inside BrowserRouter because it only allows 1 thing within.

  }

  render() {
    return (
      <div>
        <IdleTimer
          ref={ref => {
            this.idleTimer = ref;
          }}
          element={document}
          onActive={this.onActive}
          onIdle={this.onIdle}
          onAction={this.onAction}
          debounce={250}
          timeout={1000 * 60 * 0.1}
        />

        <BrowserRouter>
          <div>
            <Switch>
              <Route path="/institution" component={Institution} />
              <Route path="/location" component={Location} />
              <Route path="/timezone" component={TimeZone} />
              <Route path="/clock" component={Clock} />
              <Route path="/" component={PreflightCheck} />
            </Switch>
          </div>
        </BrowserRouter>
      </div>
    );
  }
}


ReactDOM.render(<AppRouter />, document.getElementById("root"));

重定向到BrowserRouter标记之外的顶层组件的正确方法是什么?

我也尝试过这个:

import { createHashHistory } from 'history'
export const history = createHashHistory()

然后调用history.push('/ clock');

这似乎只是将/ clock附加到我当前所在的页面上,并显示以下消息:

Hash history cannot PUSH the same path; a new entry will not be added to the history stack

创建历史记录(您可以使用npm安装历史记录):

import { createBrowserHistory } from "history";
const history = createBrowserHistory();

然后将空闲计时器放在路由器中。在这种情况下,BrowserRouter似乎无法与Router一起使用。

<Router history={history}>
      <div>

  <IdleTimer
          ref={ref => {
            this.idleTimer = ref;
          }}
          element={document}
          onActive={this.onActive}
          onIdle={() =>  this.checkplayerstatus(history)}
          onAction={this.onAction}
          debounce={250}
          timeout={1000 * 60 * 15}
        />
        <Switch>
          <Route path="/institution" component={Institution} />
          <Route path="/location" component={Location} />
          <Route path="/timezone" component={TimeZone} />
          <Route path="/clock" component={Clock} />
          <Route path="/" component={PreflightCheck} />
        </Switch>
      </div>
    </>

然后在onIdle函数中可以执行以下操作:“ whatevervariableyoupassashistoryfromonidle” .push(“ / clock”)。
