阿里天气数据接口调用实现（Java和JS）

Java实现方式

主要代码：

二 JS实现方式

var storageKey = "weather";var oldWeatherTimeKey = "oldTime";var addressKey = "address";// 根据经纬度从阿里获取天气数据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) {            // 加入缓存            localStorage.setItem(storageKey, JSON.stringify(data));            localStorage.setItem(oldWeatherTimeKey, new Date().getTime());            // 时间加入            //storage.setItem(oldWeatherTimeKey, new Date());            // 展示天气数据            showWeatherMsg(data);        },        error : function(e) {            alert("网络异常，请重试");        }    });}
