解碼示例：
String data=資料
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");
