调用天气预报以及接口出现乱码解决方法

[转载：天气预报接口(json数据，xml数据)](http://blog.csdn.net/fancylovejava/article/details/26102635)
json数据：
通过城市名字获得天气数据，json数据：
http://wthrcdn.etouch.cn/weather_mini?city=北京

通过城市id获得天气数据，json数据：
http://wthrcdn.etouch.cn/weather_mini?citykey=101010100

xml数据：
通过城市id获得天气数据，xml文件数据,当错误时会有节点
http://wthrcdn.etouch.cn/WeatherApi?citykey=101010100

通过城市名字获得天气数据，xml文件数据：
http://wthrcdn.etouch.cn/WeatherApi?city=北京
