Using TypeScript in Angular 2, obtain the name of the current location through geolocation

My current project involves retrieving my exact location (City Name) using Typescript. I am working on creating a service that can accomplish this task. Below is the code snippet I have implemented:

import { Injectable} from '@angular/core';
import { Observable } from 'rxjs/Observable';
import {Http} from '@angular/http';
import 'rxjs/Rx';

@Injectable()
export class CurrentLocationService {

    constructor(private _http: Http) {}

    getCurrentLocation(): Observable<any> {
        return this._http.get('http://ipinfo.io/json?callback=JSON_CALLBACK')
        .map(response => response.json())
        .catch(error => {
            console.log(error);
            return Observable.throw(error.json());
        });
    }
}

However, the data returned by this Service seems to be incorrect. When I manually access the URL

http://ipinfo.io/json?callback=JSON_CALLBACK
, I receive the following values:

  "city": "Munich",
  "region": "Bavaria",
  "country": "DE",

These values are accurate in my case, but the Service mentioned above incorrectly returns Connaught Place, IN as the location. Is there a more reliable way to determine the current location using a service in Typescript?

Answer №1

Make sure to omit the callback from the URL. This method has worked successfully for me. For more information, refer to the ipinfo documentation available here

fetchCurrentIpAddressDetails(): Observable<any> {
        return this._http.get('http://ipinfo.io')
        .map(response => response.json())
        .catch(error => {
            console.log(error);
            return Observable.throw(error.json());
        });
    }

Answer №2

One way to determine your current location is by using latitude and longitude coordinates:

retrieveCurrentLocation(lat,lng): Observable<any> {
    return this._http.get("http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+lng+"&sensor=true")
      .map(response => response.json())
      .catch(error => {
        console.log(error);
        return Observable.throw(error.json());
      });
  }
