签到天数: 2 天 [LV.1]初来乍到
|
需求:获取未来6天的天气预报,条用中央气象台API来实现的
有兴趣的同学可以,参考一下:代码如下
- import java.io.BufferedReader;
- import java.io.FileNotFoundException;
- import java.io.IOException;
- import java.io.InputStreamReader;
- import java.net.SocketTimeoutException;

- import net.sf.json.JSONObject;
-

-
- private String Cityid;

- private JSONObject jsonData;
- private JSONObject info;
-

- //解析本机IP地址
- this.Cityid=cityid;
-
- ///连接中央气象台的APi
- URL url=new URL("http://m.weather.com.cn/data/" + Cityid + ".html");
- connectionData = url.openConnection();
- connectionData.setConnectTimeout(1000);
- try {
- br = new BufferedReader(new InputStreamReader(connectionData.getInputStream(), "UTF-8"));
- sb = new StringBuilder();
- String line = null;
- while ((line = br.readLine()) != null){
- sb.append(line);
- }
- } catch (SocketTimeoutException e) {
- System.out.println("连接超时");
- } catch (FileNotFoundException e) {
- System.out.println("加载文件出错");
- }
-

-

-
- //得到1到6天的天气情况

- map.put("index_xc", info.getString("index_xc").toString());//洗车指数
- map.put("index_d", info.getString("index_d").toString());//天气详细穿衣指数
- list.add(map);
- }
- //控制台打印出天气
- for(int j=0;j< list.size();j++){
- Map< String,Object> wMap = list.get(j);
- System.out.println(wMap.get("city")+" "+wMap.get("date_y")+" "+wMap.get("week")+" "

- }
- }

- }
-
- public static void main(String[] args) {
- try {
