中央氣象局天氣預報介面---java實現

一:介面地址

介面地址:

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


url中的101010100是城市程式碼,這裡是北京的城市程式碼。只需要改變城市程式碼,就可以得到所在城市的天氣資訊

二:java工具類呼叫天氣介面

import java.net.URLConnection;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import net.sf.json.JSONObject;
