公众号推送早安问候以及天气预报(JAVA)

① 概述

功能点

• 每天早上可以给指定的微信用户推送消息，经过公众号

• 可以使用第三方接口丰富推送的消息内容

  • 百度天气api：添加天气信息推送
  • 天行数据api：添加美句、彩虹屁等语句推送
  • 通过后台计算纪念日推送
  • …

• 效果图

  

技术栈点

• spring boot实现后台
• 微信测试账号的申请
• 微信模版推送的配置
• 对接百度天气api
• 对接彩虹屁api
• 对接优美句子api

源码开放

Gitee

GitHub

② 注册微信测试账号，编辑推送模板

• 使用微信扫码登录此网站https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login就能得到一个微信公众号测试号

• 推送消息需要用到的信息

  

• 用户扫码关注得到用户的id

  

• 编辑消息模板

  

• 此步骤的模板id、用户微信号id、以及自己的appID、appsecret是后续推送所需要用到的

③ 使用spring boot 做后台开发，并且与第三方对接

使用第三方接口——控制台 | 百度地图开放平台 (baidu.com)

• 在百度地图开放平台注册账号，并且到控制台中的应用创建一个应用（其中应用AK是推送需要使用到的）

  

• 设置ip白名单为0.0.0.0/0

使用第三方接口——天行数据TianAPI - 开发者API数据平台

• 进去注册账号选择需要的句子接口使用就行

• 每个接口都有实例代码，直接使用就行

  

• 此案例使用了彩虹屁以及英语一句话两种

spring boot后台开发

• 创建spring boot项目，创建教程

• 导入需要的依赖

  天气的实体类

  @Data@AllArgsConstructor@NoArgsConstructorpublic class Weather {    String wd_night;    String date;    String high;    String week;    String text_night;    String wd_day;    String low;    String wc_night;    String text_day;    String wc_day;    // 当前天气    String text_now;    // 当前温度    String temp;    // 风级大小    String wind_class;    // 风向    String wind_dir;}

  public class WeatherUtils {    public static void main(String[] args) {        System.out.println(getWeather());    }    public static Weather getWeather(){        RestTemplate restTemplate = new RestTemplate();        Map<String,String> map = new HashMap<String,String>();        map.put("district_id","320583"); // 地方行政代码        map.put("data_type","all");//这个是数据类型        map.put("ak","自己的应用AK");        String res = restTemplate.getForObject(                "https://api.map.baidu.com/weather/v1/?district_id={district_id}&data_type={data_type}&ak={ak}",                String.class,                map);        JSONObject json = JSONObject.parseObject(res);        JSONArray forecasts = json.getJSONObject("result").getJSONArray("forecasts");        List<Weather> weathers = forecasts.toJavaList(Weather.class);        JSONObject now = json.getJSONObject("result").getJSONObject("now");        Weather weather = weathers.get(0);        weather.setText_now(now.getString("text"));        weather.setTemp(now.getString("temp"));        weather.setWind_class(now.getString("wind_class"));        weather.setWind_dir(now.getString("wind_dir"));        return weather;    }}

• 编写对接天行数据（彩虹屁）api的工具类

  public class CaiHongPiUtils {    public static String getCaiHongPi() {        String httpUrl = "http://api.tianapi.com/caihongpi/index?key=接口的key";        BufferedReader reader = null;        String result = null;        StringBuffer sbf = new StringBuffer();        try {            URL url = new URL(httpUrl);            HttpURLConnection connection = (HttpURLConnection) url                    .openConnection();            connection.setRequestMethod("GET");            InputStream is = connection.getInputStream();            reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));            String strRead = null;            while ((strRead = reader.readLine()) != null) {                sbf.append(strRead);                sbf.append("\r\n");            }            reader.close();            result = sbf.toString();        } catch (Exception e) {            e.printStackTrace();        }        JSONObject jsonObject = JSONObject.parseObject(result);        JSONArray newslist = jsonObject.getJSONArray("newslist");        String content = newslist.getJSONObject(0).getString("content");        return content;    }    public static Map<String,String> getEnsentence() {        String httpUrl = "http://api.tianapi.com/ensentence/index?key=接口的key";        BufferedReader reader = null;        String result = null;        StringBuffer sbf = new StringBuffer();        try {            URL url = new URL(httpUrl);            HttpURLConnection connection = (HttpURLConnection) url                    .openConnection();            connection.setRequestMethod("GET");            InputStream is = connection.getInputStream();            reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));            String strRead = null;            while ((strRead = reader.readLine()) != null) {                sbf.append(strRead);                sbf.append("\r\n");            }            reader.close();            result = sbf.toString();        } catch (Exception e) {            e.printStackTrace();        }        JSONObject jsonObject = JSONObject.parseObject(result);        JSONArray newslist = jsonObject.getJSONArray("newslist");        String en = newslist.getJSONObject(0).getString("en");        String zh = newslist.getJSONObject(0).getString("zh");        Map<String, String> map = new HashMap<>();        map.put("zh",zh);        map.put("en",en);        return map;    }}

• 编写定时任务

  @SpringBootApplication@EnableScheduling // 开启定时任务public class WechatpushApplication {    public static void main(String[] args) {        SpringApplication.run(WechatpushApplication.class, args);    }// 定时    @Scheduled(cron = "0 30 7 * * ?")    public void goodMorning(){        Pusher.push();    }}

④ 部署

• 把项目打包成jar包

  

• 把jar包上传到服务器并且运行起来

  # 运行命令nohup java -jar test.jar >temp.txt &

完成~
