本文通過(guò)一個(gè)完整的實(shí)例，講解如何通過(guò)訪(fǎng)問(wèn)中國(guó)天氣網(wǎng)提供的API接口，實(shí)現(xiàn)天氣預(yù)報(bào)功能，僅供學(xué)習(xí)分享使用，如有不足之處，還請(qǐng)指正。
涉及知識(shí)點(diǎn)
實(shí)現(xiàn)天氣預(yù)報(bào)功能的相關(guān)知識(shí)點(diǎn)：
- 天氣預(yù)報(bào)接口【提供風(fēng)向，風(fēng)速等功能】：http://www.weather.com.cn/data/sk/101120201.html
- 天氣預(yù)報(bào)接口【提供天氣基礎(chǔ)功能】：http://www.weather.com.cn/data/cityinfo/101120201.html
- 新浪網(wǎng)的接口【其中city后的是城市的名稱(chēng)轉(zhuǎn)碼】http://php.weather.sina.com.cn/xml.php?city=%B1%B1%BE%A9&password=DJOYnieT8234jlsK&day=0
- HttpWebRequest/HttpWebResponse 訪(fǎng)問(wèn)網(wǎng)絡(luò)的相關(guān)資源
- XmlSerializer 中序列化與反序列化功能
- Newtonsoft.Json中Json字符串的反序列化功能
- 泛型，委托

【上面中國(guó)天氣網(wǎng)接口讀取的數(shù)據(jù)，總感覺(jué)有些不對(duì)，不知道是不是沒(méi)有更新還是咋樣，權(quán)當(dāng)練習(xí)了】
API接口中101110101是城市的代碼，如果要查詢(xún)其他城市的天氣，只需要修改城市的代碼即可。關(guān)于城市代碼，已經(jīng)整理成配置文件xml，然后通過(guò)級(jí)聯(lián)菜單的方式進(jìn)行加載。
