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：
