中国天气预报数据API收集
想做天气APP，数据只能从别的地方接入了，以前Google的API不错，不过人家关了都不带告诉你，关了就关了，既不事先通知，事后也不发表声明！雅虎的以前还可以，现在的数据原来越少，越来越没用，所以，只能依靠天朝。本文章只供测试，如果有商业应用，请申请正规的API接口，因使用接口引起的商业纠纷与本人无关
涨姿势：
1.中央气象台：全国预报、气候预测、气候变化研究、气象信息收集分发服务的国家中心。
2.中国气象局：国务院直属事业单位。前身是中央军委气象局。承担全国气象工作的政府行政管理职能，负责全国气象工作的组织和管理。国家气象中心：（中央气象台）是中国气象局的直属事业代为之一。
3.中央气象局：这是政府机关，中央气象台是他的直属事业单位。气象局里的大都是公务员，气象台里的大都不是公务员。
天气预报只有当天和未来几天的数据接口，如果想知道历史天气，我还没找到哦。
中央气象局台的天气数据API接口有三个：

这个的数据比上面两个丰富得多，只可惜，不稳定的，而且从今年3月4号开始数据不更新了，解释是去智慧天气（http://smart.weather.com.cn/）申请试用免费的api,但是所谓免费，也只是暂定免费，后面会不会收费就不得而知了。
综合三个API，前两个数据太单薄，而且是是实时天气，没有未来的几天天气数据，满足不了需求，以前通用的第三个也不能用。对了，中国气象局的API有免费和收费模式，免费的有次数限制，用不起。如果有钱也不用，要花钱的话直接用心知天气的SDK岂不是更方便，不过真的是不便宜。去看看价格吧http://www.thinkpage.cn/weather/pricing.aspx
不要灰心，总有能用的，不然那么多APP怎么来的数据
