多个组件间的角度计时器可观察和重用订阅

当我呆在家里的时候,重新定向是正确的 component 1 让时间在50分钟后结束。但是如果我在的话,我就不会被重定向 component 2 因为某种原因。计时器仍然继续计数,直到达到限制,但就是不允许重定向。

下面是我迄今为止尝试的代码。

@Injectable()
export class TimerService {
    private readonly interval = 1000;
    private _timer$: Observable<number>;
    private _sub$: Subscription;

    constructor() {
        this._timer$ = timer(0, this.interval);
    }

    public get timer(): Observable<number> {
        return this._timer$;
    }

    public subscribe(fnExp: any): Subscription {
        if (!this._sub$) {
            this._sub$ = this._timer$.subscribe(fnExp);
        }
        return this._sub$;
    }

    public unsubscribe() {
        if (this._sub$) {
            this._sub$.unsubscribe();
        }
    }
}

ngOnInit() {
    const timerSub$ = this._timerService.subscribe(x => {
      console.log(x);
      this.count = x;
      if (x === 50) {
        this._timerService.unsubscribe();
        console.log('stopped');
        this._router.navigate(['../'], {relativeTo: this._route});
      }
    });
  }

this._router.navigate(['../'], {relativeTo: this._route})
