想在自己的android应用中获得当天的天气情况，这该怎么做呢？不用担心。中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口，我们就可以获取天气信息了。

中国国家气象局天气预报接口总共提供了三个：

http://www.weather.com.cn/data/sk/101010100.html

http://www.weather.com.cn/data/cityinfo/101010100.html

http://m.weather.com.cn/data/101010100.html

最详细的信息来自第三个接口。上面url中的101010100是城市代码，这里是北京的城市代码。只需要改变城市代码，就可以得到所在城市的天气信息。笔者在福州，所以选择的城市代码是福州101230101。

在浏览器上输入url：http://m.weather.com.cn/data/101230101.html得到信息，天气信息是json的数据格式，数据如下：

{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14 日","date":"","week":"星期 一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":" 阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨 转阵雨","weather6":"阵雨转小 雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":" 阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":" 小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":" 小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小 雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微 风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小 于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3 级","index":"热","index_d":"天气较热，建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单 裤。","index48":"暖","index48_d":"较凉爽，建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长 裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适 宜","index_co":"较不舒 适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":" 较不宜","index_ls":"不太适宜","index_ag":"不易发"}}

我们可以解析json数据去得到自己想用的天气信息。

还有一个方法，请求http://61.4.185.48:81/g/，通过它，你会直接得到城市代码。更方便。
