使用json解析国家气象局（天气预报）接口数据

 平时我们在开发的过程中有时会要用到天气预报的信息，国家气象局为我们提供了天气预报的接口，只需要我们去解析就行了。很方便很好用

      那么下面，我们开始吧！

 

国家气象局提供了三种数据的形式

 

网址在：

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

最后一种是解析最全面的。

这里再附上中国天气网城市代码大全（百度文库里面的），把后面的城市代码换下就行了：

http://wenku.baidu.com/view/ea286102bb68a98271fefad8.html

 

数据解析格式：

第一个网址提供的json数据为：

{"weatherinfo":{"city":"北京","cityid":"101010100","temp":"-2","WD":"西北风","WS":"3级","SD":"241%","WSE":"3","time":"10:61","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB"}}

第二个网址提供的json数据为：

{"weatherinfo":{"city":"北京","cityid":"101010100","temp1":"3℃","temp2":"-8℃","weather":"晴","img1":"d0.gif","img2":"n0.gif","ptime":"11:00"}}

第三个网址提供的json数据较为全面：

字段言简意赅，城市名，英文名，日期，农历日期，星期，预报时间，城市代码，6个预报温度（华氏温度，摄氏温度），6个预报天气和风力，剩下的就是一些气象指数。

 　　之前有朋友提到过，希望把各个城市的城市代码也整理一下，这样的话，可以跟方便的使用，经过查找，在百度文库里面找到一篇详细的城市代码。大家可以去查看，地址如下，祝大家使用愉快：

Android天气预报之基于HttpGet对象解析天气数据的方法

本文实例所述为Android天气预报之解析天气数据的代码，可实现获取HttpGet对象读取天气网站天气数据，并从数据中解析出天气数据，比如温度、温度、风力、风向、未来几天天气趋势、当天天气状况、空气污染指数等信息，还包括了调用对应的图片或天气动画文件，对于开发android天气预报程序的可以参考本文实例。

具体功能代码如下：
