全網、全國最好用的基于經緯度的天氣查詢、天氣預報接口

      大家好，我們是中國科學院資源與環境信息系統國家重點實驗室的人員（學生）。在軟件開發進程中，我們發現，傳統獲得天氣信息的接口大多是基于所謂的天氣碼，數據源大多來自中國國家氣象局；隨著移動http://www.vxbq.cn/Internet/的快速發展，大家都希望通過經緯度查詢天氣信息。
       最開始我們搜索全網，發現谷歌提供了利用經緯度獲得天氣信息的接口，但是1測試發現，由于“你懂的”緣由，它已沒法使用了。國內IT3哥――百度貌似也提供了這么1個接口，但是又是需要神馬key啊，驗證文件啊等等1堆手續；而且它還限制每天的單個IP的訪問次數，更讓人討厭的是，它只提供3天的天氣預報信息。其他的接口大多數是通過使人深惡痛絕的天氣碼獲得，基本都不好用。
       我們本著逢山開路，遇水疊橋的精神，痛下決心，利用了點我們實驗室所謂的強項――GIS技術，自己制作了天氣預報，天氣查詢接口。天氣查詢接口支持全國任何地區的天氣信息查詢，數據精確到區縣級別。天氣預報接口提供5天以內的天氣預報信息。

       下面介紹1下天氣接口和其使用方法。天氣查詢接口為：

http://www.missfeng.com/iserver/services/GetOverallWeatherComponent/restjsr/GetOverallWeather

/"longitude"/"latitude".rjson。這個接口的訪問方式為HttpGet，接口中只有兩個參數"longitude"和"latitude"，替換成你定位取得的經緯度便可。例如：    http://www.missfeng.com/iserver/services/GetOverallWeatherComponent/restjsr/GetOverallWeather/116.3/40.rjson獲得的是北京海淀區的天氣信息。這個接口要求返回的是1個json，json的格式為：{"weatherinfo":{"city":"海淀","cityid":"101010200","temp1":"14℃","temp2":"9℃","weather":"小雨轉陰","img1":"d7.gif","img2":"n2.gif","ptime":"08:00","temp":"12","WD":"北風","WS":"0級","SD":"86%","WSE":"0","time":"09:35","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB","njd":"暫無實況","qy":"1018"}}

         其中：weatherinfo代表天氣信息，city代表所在地，cityid是中國氣象局給全國縣市的編碼，temp1代表當地當日最高氣溫，temp2代表當日當地最低氣溫，weather代表當日天氣狀態，img1代表白每天氣狀態的圖標，img2代表夜晚天氣狀態的圖標，圖片資源的訪問地址為http://m.weather.com.cn/img/d7.gif，其中d7.gif為獲得的img；ptime為天氣信息發布的時間，temp為發布時的氣溫，WD為風向，WS為風級，SD為濕度，WSE為風力，time代表雷達圖更新時間，isRadar代表是不是有雷達圖，Radar代表雷達圖的訪問地址，njd為能見度信息，qy為當前氣壓信息。

        天氣預報接口為：http://www.missfeng.com/iserver/services/GetDetailedWeatherComponent/restjsr

/GetDetailedWeather/"longitude"/"latitude".rjson，其中"longitude"/"latitude"分別為經度、緯度參數例如：

 http://www.missfeng.com/iserver/services/GetDetailedWeatherComponent/restjsr/GetDetailedWeather/118.3/37.1.rjson。返回的json為：

 ({"time":1414719933,"area":[["山東","12"],["濱州","1211"],["博興","101121102"]],"weather":[{"date":"2014⑴0⑶1","info":{"day":["7","小雨","18","東北風","微風"],"night":["7","小雨","11","東風","微風"]}},{"date":"2014⑴1-01","info":{"dawn":["7","小雨","11","東風","微風"],"day":["7","小雨","16","西北風","微風"],"night":["7","小雨","9","西北風","3⑷ 級"]}},{"date":"2014⑴1-02","info":{"dawn":["7","小雨","9","西北風","3⑷ 級"],"day":["1","多云","14","西北風","3⑷ 級"],"night":["0","晴","5","西北風","微風"]}},{"date":"2014⑴1-03","info":{"dawn":["0","晴","5","西北風","微風"],"day":["0","晴","17","無延續風向","微風"],"night":["0","晴","5","無延續風向","微風"]}},{"date":"2014⑴1-04","info":{"dawn":["0","晴","5","無延續風向","微風"],"day":["0","晴","18","無延續風向","微風"],"night":["1","多云","8","無延續風向","微風"]}}],"pm25":[]});   
        其中area代表當前的區域，weather代表當前的天氣信息，天氣信息由day 白天；night 夜晚；和dawn傍晚信息組成，單個信息塊里是最低溫度，天氣，風向，風級的格式，比方["7","小雨","11","東風","微風"]分別是最低溫度為7度，天氣為小雨，風向為東風，風級為微風。
