날씨가 출력 되지 않는 오류

출처 : 스마트미러 forecast 오류해결방법(GeolocationService 문제) - 징징이 : 네이버 블로그

날씨를 표시 못하는 문제가 발생했다. 

두가지 문제로 첫 번째는 위치 정보를 못 받아 오는 문제인데, 구글에 브라우져를 통해서 위치 정보를 받아 오는 함수가 될때가 있고, 안 될때가 있는데, 위치 정보를 수동으로 설정하는 방법으로 해결이 되지만, 

두 번째 문제로 날씨 정보 서비스가 한글을 지원하지 못하는 문제가 있어 영어(en) 으로 고정해야 날씨 정보를 조회 한다.

위치정보 수동 설정

plugins\weather\controller.js 내용수정

아래와 같이 소스를 영어로 고정하면 날씨 정보를 조회 한다.

	weather.get = function () {
		var weather_url = 'https://api.darksky.net/forecast/' + config.forecast.key + '/' +
            geoposition.coords.latitude + ',' + geoposition.coords.longitude + '?units=' +
            //config.forecast.units + "&lang=" + language + "&callback=JSON_CALLBACK";
            config.forecast.units + "&lang=en" + "&callback=JSON_CALLBACK";
		console.log(weather_url);
		return $http.jsonp(weather_url).then(function (response) {
			return weather.forecast = response;
		});
	};

위치정보 조회 서비스 호출 부분 (참고용)

위치정보 조회 서비스가 성공하면 interval 함수 호출로 주기적으로 날씨 정보를 조회 한다.

	GeolocationService.getLocation({ enableHighAccuracy: true }).then(function (geopo) {
		geoposition = geopo;
		refreshWeatherData(geoposition);
		$interval(refreshWeatherData, config.forecast.refreshInterval * 60000 || 7200000)
	});
