获取天气信息作者是通过高德开放平台来实现的。
1、在该平台注册个账号
如已经注册，直接登录即可。
2、创建应用
创建成功后获取到key值。（注意该值会经常用到，且可以共用保存好）
3、进入开发文档选择天气查询
开发文档
下面按照说明使用即可。
接下来上代码。（注意功能接受的是JSON格式的）
4、pom.xml文件的引用
|
1 2 3 4 5 |
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.80</version> </dependency> |
5、配置文件
无
6、实体类
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
package com.zjh.weixin.Model;
import lombok.Data;
import java.util.List;
/** * @Author: zjh * @Date: 2022/9/19 11:03 * @Description: 天气总实体 * @Version: v1.0 */ @Data public class WeatherModel { private String status; private String count; private String nfo; private String infocode; private List<LivesModel> lives; } |
该实体为总实体（后续添加功能时，在总实体添加引用，在创建子实体）
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
package com.zjh.weixin.Model;
import lombok.Data;
/** * @Author zjh * @Date 2022/9/19 1053 * @Description 天气实体类 * @Version v1.0 */ @Data public class LivesModel { private String province; private String city; private String adcode; private String weather ; private String temperature ; private String winddirection; private String windpower; private String humidity; private String reporttime ; } |
该类为子实体
7、根据路径获取信息
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
package com.zjh.weixin.Util;
import org.springframework.http.HttpEntity; import org.springframework.http.HttpHeaders; import org.springframework.http.MediaType; import org.springframework.web.client.RestTemplate; import com.alibaba.fastjson.JSON; import java.util.Map;
/** * @Author: zjh * @Date: 2022/9/19 10:29 * @Description: 后端根据路径发起请求 * @Version: v1.0 */ public class HttpsUtil { /** * get请求 */ public static String get(String url){ HttpHeaders headers = new HttpHeaders(); MediaType mediaType = MediaType.parseMediaType("application/json; charset=UTF-8"); headers.setContentType(mediaType); RestTemplate restTemplate = new RestTemplate(); String result = restTemplate.getForObject(url, String.class); return result; } } |
8、调用方法
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
public static void main(String[] args) { String url = "https://restapi.amap.com/v3/weather/weatherInfo?city=411400&key=b2f301************077d21"; String s = HttpsUtil.get(url); System.out.println(s); JSONObject object = JSONObject.parseObject(s); WeatherModel jb = (WeatherModel)JSONObject.toJavaObject(object, WeatherModel.class); System.out.println(jb); LivesModel livesModel = jb.getLives().get(0); System.out.println(livesModel); int c =Integer.valueOf(livesModel.getTemperature()); SimpleDateFormat dateFm = new SimpleDateFormat("EEEE"); String currSun = dateFm.format(new Date()); String r = null; if (c<=26 && c>=18){ r="今天温度适宜"; }else if (c>26){ r="今天温度较高,注意防晒"; }else if(c<18){ r="今天温度较低,注意保暖"; } String zong = "日期: "+livesModel.getReporttime()+" "+currSun+"\n"+ "所在城市: "+livesModel.getCity()+"\n"+ "天气: " + livesModel.getWeather()+"\n"+ "温度: "+ livesModel.getTemperature()+" "+r+"\n"+ "风向: "+ livesModel.getWinddirection()+"风"+"\n"+ "风级: "+livesModel.getWindpower(); System.out.println(zong);
} |
成功返回数据
9、项目优化
高德开放平台根据地址获取城市编码
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 |
public static String getWeather(String adcode,String key){ String url = "https://restapi.amap.com/v3/weather/weatherInfo?city="+adcode+"&key="+key; String s = HttpsUtil.get(url); JSONObject object = JSONObject.parseObject(s);
WeatherModel jb = (WeatherModel)JSONObject.toJavaObject(object, WeatherModel.class); LivesModel livesModel = jb.getLives().get(0); int c =Integer.valueOf(livesModel.getTemperature()); SimpleDateFormat dateFm = new SimpleDateFormat("EEEE"); String currSun = dateFm.format(new Date()); String r = null; if (c<=26 && c>=18){ r="今天温度适宜"; }else if (c>26){ r="今天温度较高,注意防晒"; }else if(c<18){ r="今天温度较低,注意保暖"; } String zong = "日期: "+livesModel.getReporttime()+" "+currSun+"\n"+ "所在城市: "+livesModel.getCity()+"\n"+ "天气: " + livesModel.getWeather()+"\n"+ "温度: "+ livesModel.getTemperature()+" "+r+"\n"+ "风向: "+ livesModel.getWinddirection()+"风"+"\n"+ "风级: "+livesModel.getWindpower(); return zong; } private static String getCityCode(String adress,String key){ String url = "https://restapi.amap.com/v3/geocode/geo?address="+adress+"&key="+key; String s = HttpsUtil.get(url); JSONObject object = JSONObject.parseObject(s); System.out.println(object); JSONArray array = (JSONArray) object.get("geocodes"); JSONObject arrayObject = (JSONObject) array.get(0); String adcode = arrayObject.get("adcode").toString(); return adcode; }
public static void main(String[] args) {
System.out.println(getCityCode("河南省郑州市","b2f301c36******77d21")); System.out.println(getWeather(getCityCode("河南省郑州市","b2f3*****7d21"),"b2f3*******7d21")); } |
注：该功能虽说是springboot项目，但是缺失许多东西，不太完善(其主要原因是因为作者发现通过java编程实现通过用户账号发送给该用户的好友信息，只能通过Robot的自动测试功能实现微信发送消息。该方法缺点太大，不太方便，暂时未找到其他更好的方法
