Java通过经纬度调用天气接口（YY天气）

调用接口，首先得去注册一个账号，这个账号是我同事注册的，我也只在这里提一下（它只能获取当天的数据，没有百度API的功能强大），但是JAVA实现的方法和思路都是一样的

package com.common.filo;
    
    import java.io.BufferedReader;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    import java.net.URL;
    import java.net.URLConnection;
    import java.util.ArrayList;
    import java.util.List;
    import net.sf.json.JSONArray;
    import net.sf.json.JSONObject;
    
    public class weatherApi { 
    
        public static void main(String[] args) {
            //31.874000,101.110880,3362.300
            String weidu = "101.110880";
            String jindu = "31.874000";
    
            String weatherData = getWeatherData(weidu,jindu);
            List getWeather = GetWeather(weatherData);
            for (Object object : getWeather) {
                System.out.println(object.toString());
            }
    
    
        }
        /** * 根据经纬度获取城市的气温信息 * @param weidu 纬度 * @param jindu 经度 * @return */
        public static String getWeatherData(String weidu,String jindu) {
            StringBuilder sb = new StringBuilder();
            //http://api.yytianqi.com/weatherhours?key=bopi3li1ip93ae0n&city=31.874000,101.110880"
            try {
                String weather_url = "http://api.yytianqi.com/weatherhours?key=bopi3li1ip93ae0n&city="+weidu+","+jindu+"";
                URL url = new URL(weather_url);
                URLConnection conn = url.openConnection();
                InputStream inputStream = conn.getInputStream();
                InputStreamReader inputStreamReader = new InputStreamReader(inputStream,"utf-8");
                BufferedReader reader = new BufferedReader(inputStreamReader);
                String line = null;
                while((line=reader.readLine())!=null) {
                    sb.append(line+" ");
                }
                reader.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
            return sb.toString();
        }
    
        /** * 对调用天气API的数据进行json序列化 * @param weatherJson * @return */
        public static List<String> GetWeather(String weatherJson) {
            //城市名
            String cityname= "";
            //获取当时的气温
            String qw = "";
            List<String> list = new ArrayList<String>();
            JSONObject dataJson = JSONObject.fromObject(weatherJson.trim());
            String getCode = dataJson.getString("msg");
            //如果没有获取到信息，则返回未知
            if(getCode.equals("Error")) {
                cityname = "未知";
                qw = "未知";
                list.add(cityname);
                list.add(qw);
                return list;
            }else {
                String data = dataJson.getString("data");
                dataJson = JSONObject.fromObject(data);
                cityname = dataJson.getString("cityName");
                JSONArray qwlist = dataJson.getJSONArray("list");
                JSONObject result = qwlist.getJSONObject(0);
                qw = result.getString("qw");
                qw = qw+"℃";
                list.add(cityname);
                list.add(qw);
            }
                return list;
        } 
    }

调用API获取到的数据：
