Java开发如何利用高德地图api解析并显示天气信息

Java获取天气信息

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public static JSONObject getWeatherInfo(String adcode, String key) throws Exception {
 String url = "https://restapi.amap.com/v3/weather/weatherInfo";
 String requestUrl = url + "?key=" + key + "&city=" + adcode;
  
 URL obj = new URL(requestUrl);
 HttpURLConnection con = (HttpURLConnection) obj.openConnection();
 con.setRequestMethod("GET");
  
 BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream(), "UTF-8"));
 String inputLine;
 StringBuilder response = new StringBuilder();
  
 while ((inputLine = in.readLine()) != null) {
     response.append(inputLine);
 }
 in.close();
  
 JSONObject result = JSONObject.parseObject(response.toString());
 return result;
}

Java解析并显示天气信息

public static void main(String[] args) {
 try {
   String adcode = "城市编码"; // 例如：110000（北京市）
   String key = "你的开发者Key";
 
   JSONObject weatherInfo = getWeatherInfo(adcode, key);
   JSONArray forecasts = weatherInfo.getJSONArray("forecasts");
   JSONObject todayForecast = forecasts.getJSONObject(0);
   JSONArray casts = todayForecast.getJSONArray("casts");
    
   for (int i = 0; i < casts.size(); i++) {
     JSONObject cast = casts.getJSONObject(i);
     String date = cast.getString("date");
     String week = cast.getString("week");
     String dayWeather = cast.getString("dayweather");
     String nightWeather = cast.getString("nightweather");
      
     System.out.println(date + " " + week + " " + dayWeather + "转" + nightWeather);
   }
 } catch (Exception e) {
   e.printStackTrace();
 }
}
