1. XML接口 http://flash.weather.com.cn/wmaps/xml/china.xml 這個是全國天氣的根節(jié)點，列出所有的省，其中的pyName字段是各個省XML的文件名，比如北京的是beijing，那就意味著北京的XML地址為 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(shù)據(jù)，北京就列出各個區(qū)。 tmp1是最低溫低，tmp2是最高溫度，url非常重要，我們一會兒再說。state1和state2是神馬轉(zhuǎn)神馬，每個數(shù)代表一個天氣現(xiàn)象。天氣現(xiàn)象非常多，我本想全部分析出來，后來直接放棄了這個想法。因為我看到了一個城市的天氣現(xiàn)象的編碼是26...我現(xiàn)在知道的有0.晴 1.多云 2.陰 6.雨夾雪 7.小雨 8.中雨 13.陣雪 14.小雪 其中后來發(fā)現(xiàn)知道這個沒用，這個數(shù)字的主要作用是檢索圖片的�。�！
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(xiàn)象0（晴）的圖片，其他天氣現(xiàn)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(biāo)，29*20像素，n打頭的是夜間反白圖標(biāo)，29*20像素，注意這里的文件名是兩位數(shù)字！ 也許還有更多的圖標(biāo)，等待大家發(fā)掘啦~
3. JSON接口 真沒想到~居然有JSON接口~JSON在iPhone上分析起來要比XML簡單很多 http://m.weather.com.cn/data/101010200.html 這個是北京的JSON數(shù)據(jù)，那個HTML的名字是根據(jù)上文XML中的url得到的。這個JSON中包含了實時數(shù)據(jù)、7天天氣預(yù)報、氣象指數(shù)等豐富的數(shù)據(jù)
獲取省級代碼：http://www.weather.com.cn/data/list3/city.xml?level=1
獲取城市代碼(比如安徽是22)：http://www.weather.com.cn/data/list3/city22.xml?level=2
獲取區(qū)域代碼（比如安慶是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
然后去加上中國代碼請求URL：http://m.weather.com.cn/data/101220607.html
就可以獲取當(dāng)?shù)靥鞖狻?/p>
另外再給幾個有用的探索得到的URL：
