二 JS實(shí)現(xiàn)方式

var storageKey = "weather"; var oldWeatherTimeKey = "oldTime"; var addressKey = "address"; // 根據(jù)經(jīng)緯度從阿里獲取天氣數(shù)據(jù) function getWeatherMsg(lon, lat) {var url = "https://ali-weather.showapi.com/gps-to-weather?from=5&lat=" + lat + "&lng=" + lon + "&need3HourForcast=0&needAlarm=0&needHourData=0&needIndex=0&needMoreDay=1";$.ajax({url : url,type : "get",beforeSend : function(req) {req.setRequestHeader("Authorization", "APPCODE acacbfc4fac24722996q34b284935353562340cd77c8be");},dataType : "json",success : function(data) {// 加入緩存localStorage.setItem(storageKey, JSON.stringify(data));localStorage.setItem(oldWeatherTimeKey, new Date().getTime());// 時(shí)間加入//storage.setItem(oldWeatherTimeKey, new Date());// 展示天氣數(shù)據(jù)showWeatherMsg(data);},error : function(e) {alert("網(wǎng)絡(luò)異常，請(qǐng)重試");}}); }
