如何从地址获取纬度和经度?
我目前的方法是将地址传递给谷歌地图 api:
getLocationJson(term: string) {
var term = "Mechelsesteenweg+64";
return this._http.get('https://maps.googleapis.com/maps/api/geocode/json?address=Someroad+64&key=AIzkeystuffjXDm6eU5mPP9Nczg')
.subscribe((json: any) => {
var obj = JSON.parse(json);
var jsonParsed = obj["results"];
});
}
但我觉得这不是正确的方法。我可以为此使用地理编码器吗?像这样:
getGeoLocation(address: string) {
let geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latlng = google.maps.location.LatLng();
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
提前谢谢。(基本上是这个问题,但反过来了(
我回答了您链接的问题,这是对我有用的方法:
getGeoLocation(address: string): Observable<any> {
console.log('Getting address: ', address);
let geocoder = new google.maps.Geocode();
return Observable.create(observer => {
geocoder.geocode({
'address': address
}, (results, status) => {
if (status == google.maps.GeocoderStatus.OK) {
observer.next(results[0].geometry.location);
observer.complete();
} else {
console.log('Error: ', results, ' & Status: ', status);
observer.error();
}
});
});
}
