地理位置问题 - 离子2

标签： cordova ionic-framework ionic2

我正在尝试获取用户的位置（纬度和经度）但是由于某种原因它不起作用。它适用于浏览器，但不适用于手机或模拟器。这是我的代码。

constructor(public navCtrl: NavController, public _http:Http, public alertCtrl:AlertController, public zone:NgZone, public platform:Platform, public loadingCtrl:LoadingController){        
  this.platform.ready().then(() => {
    if(navigator.geolocation){
        console.log('Condition is true');
        Geolocation.getCurrentPosition().then((position) => {
          console.log(position);
          }, (err) => {
            console.error(err);
          });
    }else{
      console.error("Navigator is unavailable");
    }
});}

在控制台中，我得到Condition is true，但这是唯一的控制台日志，我什么也没得到。

版本和插件

Cordova版本6.4.0

离子版2.1.4

cordova-plugin-geolocation 2.4.0“Geolocation”

按照步骤：

  1. 离子运行android
  2. 关闭GPS
  3. 打开GPS
  4. 关闭应用
  5. 打开应用

    6. 这是因为应用程序处于调试模式，并且与应用程序使用GPS的权限相关

试试这个代码对我有用。

答案 2 :(得分：0)

这就是我使用的。

import {Geolocation} from 'ionic-native';

export class someThing {
   data: any;

constructor(public navCtrl: NavController, public alertCtrl: AlertController) {
    Geolocation.getCurrentPosition().then((resp) => {
        let lat = resp.coords.latitude;
        let lng = resp.coords.longitude;
        this.data.lat = lat;
        this.data.lng = lng;
    });
}

} 您能发布index.html文件和config.xml

吗？

答案 3 :(得分：0)

我做了下面的代码，你可以在我的github https://github.com/prolland006/ionic2-geoloc/blob/master/src/services/background-geolocation-service.ts

中找到一个例子 
 Geolocation.getCurrentPosition(this.foreGroundOptions)
        .then((position: Geoposition) => {
            this.trace.info(`Foregrnd current ${position.coords.latitude},${position.coords.longitude}`);
        }).catch((error)=>{
            if ((error.code == undefined) || (error.code != 3)) { //3=timeout
                this.trace.error('BackgroundGeolocationService', 'refreshLocations', `error Foregrnd.getCurrentPos:${error.toString()}`);
            }
        });

也许你忘记了选项

  // Foreground Tracking
foreGroundOptions = {
    frequency: 2000,
    enableHighAccuracy: true,
    maximumAge: Infinity,
    timeout: 2000
};
