1. Geolocation
사용자의 위치 정보를 알아올 수 있는 함수
navigator.geolocation.getCurrentPosition()
두 가지 인자를 받는데 첫번째는 위치 불러오는 것이 성공했을 때 실행될 함수와 실패했을 때의 함수임.
JS (HTML 파일에 알아서 jS랑 연결)
function onGeoOk(position) {
const lat = position.coords.latitude;
const lng = position.coords.longitude;
console.log("You live in",lat,lng);
}
function onGeoError() {
alert("can't find you. No weather for you");
}
navigator.geolocation.getCurrentPosition(onGeoOk, onGeoError);2. Weather API
API 는 해당사이트에 들어가서 회원 가입해서 가져옴
https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid={API key}
이게 API를 불러오는 url임
여기에 내 위도와 경도를 넣어주고 API 키를 넣어주면 되는 것임.
