國家氣象局免費天氣預報接口API

　　在應用開發中，咱們經常會用到天氣預報的信息，其實不少網站都已經提供了免費的天氣預報API，咱們直接調用就能夠獲取，下面就介紹一下國家氣象局提供的天氣預報API接口。

　　1.XML接口http://flash.weather.com.cn/wmaps/xml/china.xml這個是全國天氣的根節點，列出全部的省，其中的pyName字段是各個省XML的文件名，好比北京的是beijing，那就意味着北京的XML地址爲http://flash.weather.com.cn/wmaps/xml/beijing.xml一個省的天氣，其中列出該省各個市的數據，北京就列出各個區。tmp1是最低溫低，tmp2是最高溫度，url很是重要，咱們一下子再說。state1和state2是神馬轉神馬，每一個數表明一個天氣現象。天氣現象很是多，我本想所有分析出來，後來直接放棄了這個想法。由於我看到了一個城市的天氣現象的編碼是26...我如今知道的有0.晴1.多雲2.陰6.雨夾雪7.小雨8.中雨13.陣雪14.小雪其中後來發現知道這個沒用，這個數字的主要做用是檢索圖片的！！！

　　2.圖片接口 http://m.weather.com.cn/img/c0.gif

http://m.weather.com.cn/img/b0.gif

http://www.weather.com.cn/m/i/weatherpic/29x20/d0.gif

http://www.weather.com.cn/m2/i/icon_weather/29x20/n00.gif

這個圖就是天氣現象0（晴）的圖片，其餘天氣現象的圖片依此類推。c打頭的圖片是20*20像素的，b打頭的是50*46像素的，d打頭的是反白的圖標，29*20像素，n打頭的是夜間反白圖標，29*20像素，注意這裏的文件名是兩位數字！也許還有更多的圖標，等待你們發掘啦~

　　3.JSON接口真沒想到~竟然有JSON接口~JSON在iPhone上分析起來要比XML簡單不少 http://m.weather.com.cn/data/101010200.html 這個是北京的JSON數據，那個HTML的名字是根據上文XML中的url獲得的。這個JSON中包含了實時數據、7每天氣預報、氣象指數等豐富的數據 獲取省級代碼：   http://www.weather.com.cn/data/list3/city.xml?level=1

　　獲取城市代碼(好比 安徽是22)： http://www.weather.com.cn/data/list3/city22.xml?level=2

　　獲取區域代碼（好比安慶是2206）： http://www.weather.com.cn/data/list3/city2206.xml?level=3

　　獲取到安徽省安慶市望江縣的代碼是220607

　　而後去加上中國代碼請求URL： http://m.weather.com.cn/data/101220607.html
　　就能夠獲取當地天氣。

      城市代碼剛添加的數據庫，須要的能夠留下郵箱。。。

      我郵箱zjd0827@163.com 　　另外再給幾個有用的探索獲得的URL： 　　天氣FLASH實況：http://flash.weather.com.cn/sk2/101220607.xml 　　實況FLASH：http://flash.weather.com.cn/sk2/shikuang.swf?id=101220607 　　三級選擇菜單（註明，這裏有四個INPUT，其中有一個被隱藏了，可用FIREFOX改下源代碼查看）：http://www.weather.com.cn/static/custom/search3.htm 　　實時天氣（頗有用哦）：http://www.weather.com.cn/data/sk/101220607.html
