平時我們在開發的過程中有時會要用到天氣預報的資訊，國家氣象局為我們提供了天氣預報的接口，隻需要我們去解析就行了。很友善很好用
那麼下面，我們開始吧！
國家氣象局提供了三種資料的形式
網址在：
最後一種是解析最全面的。
這裡再附上中國天氣網城市代碼大全(百度文庫裡面的)，把後面的城市代碼換下就行了：
資料解析格式：
第一個網址提供的json資料為：
{"weatherinfo":{"city":"北京","cityid":"101010100","temp":"-2","WD":"西北風","WS":"3級","SD":"241%","WSE":"3","time":"10:61","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB"}}
第二個網址提供的json資料為：
{"weatherinfo":{"city":"北京","cityid":"101010100","temp1":"3℃","temp2":"-8℃","weather":"晴","img1":"d0.gif","img2":"n0.gif","ptime":"11:00"}}
第三個網址提供的json資料較為全面：

字段言簡意赅，城市名，英文名，日期，農曆日期，星期，預報時間，城市代碼，6個預報溫度(華氏溫度，攝氏溫度)，6個預報天氣和風力，剩下的就是一些氣象指數。
之前有朋友提到過，希望把各個城市的城市代碼也整理一下，這樣的話，可以跟友善的使用，經過查找，在百度文庫裡面找到一篇詳細的城市代碼。大家可以去檢視，位址如下，祝大家使用愉快：
