一、概要：
此天气WCF使用的是中国天气的Json天气数据接口。
另外，由于文章并没有讲解具体的WCF创建过程，所以在文章最后笔者会提供一个笔者自己的完成品以供大家参考。

其中101120201就是每个城市的代码。
Json数据的基本结构

使用此接口的优点是比较稳定，信息也比较准确。缺点是比较容易找到的城市代号目前只有省级市的，像一些县级市只能根据情况自己添加了。（最后笔者会提供一个Json结构的城市列表）
实现此天气的WCF服务，主要可分为四个功能：
1、根据IP获取用户的所有省份和城市。（如果需要自动识别用户地理位置返回天气情况的话）
4、获取此服务所有支持的城市。（此功能作为附加，更方便使用者）
二、数据结构
1、城市基本天气信息
