解码示例：

String data=数据
JSONObject jo=new JSONObject(data);
JSONArray ja=jo.getJSONArray("HeWeather6");
JSONObject joo=ja.getJSONObject(0);
JSONArray daily=joo.getJSONArray("daily_forecast");
for(int i=0;i<daily.length();i++)
{
     JSONObject day=daily.getJSONObject(i);
     String date=day.getString("date");
     String weather=day.getString("cond_txt_d");
     //获取其他数据
}
