离子背景地理定位 - 开始跟踪不在间隔中工作

Question

我每隔60秒跟踪设备位置。这意味着startTracking()函数需要放在一个区间内。看来，当我这样做时，我没有收到请求，但在我的控制台中看起来gps正在更新，请求就是没有被调用。当我没有在一个区间中放置startTracking()函数时，它会获得初始GPS位置（显然）并且它没有更新，因为它没有被放置在一个区间中但是正在发送请求。

位置的service.ts

startTracking() {

    const config: BackgroundGeolocationConfig = {
      desiredAccuracy: 10,
      stationaryRadius: 20,
      distanceFilter: 30,
      debug: false, //  enable this hear sounds for background-geolocation life-cycle.
      stopOnTerminate: false
  };

  this.backgroundGeolocation.configure(config)
  .subscribe((location: BackgroundGeolocationResponse) => {


  this.lat = location.latitude
  this.lng = location.longitude
  this.bearing = location.bearing
  this.speed = location.speed
  this.accuracy = location.accuracy
  this.timestamp = location.time

  this.backgroundGeolocation.finish(); // FOR IOS ONLY

  });

  this.gpsProvided = this.diagnostic.isLocationAvailable().then(res => {
    return res;
  });
  this.manifestID = this.events.subscribe('manifestid', maniID => {
    return maniID
  });

  this.backgroundGeolocation.start();
  }


 stopTracking() {

          let url = 'some URL';
          let request = {
              Latitude: this.lat,
              Longitude: this.lng,
              Speed: this.speed,
              Accuracy: this.accuracy,
              Bearing: this.bearing
          };
          let headers = new Headers({ 'Content-Type': 'application/json' });
          let options = new RequestOptions({ headers: headers });
          let body = JSON.stringify(request);
          this.backgroundGeolocation.stop();
          return this.http.post(url,body,options).subscribe((data) => {
          });

 }

app.component.ts（无间隔）

constructor(){
this.sendGPSStart()
this.GPSInterval()
}

sendGPSStart(){
    this.locationTracker.startTracking();
  }

  sendGPSStop(){
    this.locationTracker.stopTracking();
  }

GPSInterval(){
    setInterval(() => {

          this.sendGPSStop() 

      })
    }, 60000)
  }
