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

    在这里插入图片描述

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

    在这里插入图片描述

  • 用户扫码关注得到用户的id

    在这里插入图片描述

  • 编辑消息模板

    在这里插入图片描述

  • 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）

    在这里插入图片描述

  • 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

    在这里插入图片描述

  • 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

  • 编写计算纪念日的工具类

    public class JiNianRiUtils {

    public static int getLianAi(){
        return calculationLianAi("2022-12-11");
    }
    public static int getBirthday_Jo(){

  • 编写推送类

    /**
 * @author cVzhanshi
 * @create 2022-08-04 21:09
 */
public class Pusher {

    public static void main(String[] args) {
        push();
    }
    private static String appId = "xx";
    private static String secret = "xx";



    public static void push(){
        //1，配置
        WxMpInMemoryConfigStorage wxStorage = new WxMpInMemoryConfigStorage();
        wxStorage.setAppId(appId);
        wxStorage.setSecret(secret);
        WxMpService wxMpService = new WxMpServiceImpl();
        wxMpService.setWxMpConfigStorage(wxStorage);
        //2,推送消息
        WxMpTemplateMessage templateMessage = WxMpTemplateMessage.builder()
                .toUser("用户微信id") 
                .templateId("消息模板id")
                .build();
        //3,如果是正式版发送模版消息，这里需要配置你的信息
        Weather weather = WeatherUtils.getWeather();
        Map<String, String> map = CaiHongPiUtils.getEnsentence();
        templateMessage.addData(new WxMpTemplateData("riqi",weather.getDate() + "  "+ weather.getWeek(),"#00BFFF"));
        templateMessage.addData(new WxMpTemplateData("tianqi",weather.getText_now(),"#00FFFF"));
        templateMessage.addData(new WxMpTemplateData("low",weather.getLow() + "","#173177"));
        templateMessage.addData(new WxMpTemplateData("temp",weather.getTemp() + "","#EE212D"));
        templateMessage.addData(new WxMpTemplateData("high",weather.getHigh()+ "","#FF6347" ));
        templateMessage.addData(new WxMpTemplateData("windclass",weather.getWind_class()+ "","#42B857" ));
        templateMessage.addData(new WxMpTemplateData("winddir",weather.getWind_dir()+ "","#B95EA3" ));
        templateMessage.addData(new WxMpTemplateData("caihongpi",CaiHongPiUtils.getCaiHongPi(),"#FF69B4"));
        templateMessage.addData(new WxMpTemplateData("lianai",JiNianRiUtils.getLianAi()+"","#FF1493"));
        templateMessage.addData(new WxMpTemplateData("shengri1",JiNianRiUtils.getBirthday_Jo()+"","#FFA500"));
        templateMessage.addData(new WxMpTemplateData("shengri2",JiNianRiUtils.getBirthday_Hui()+"","#FFA500"));
        templateMessage.addData(new WxMpTemplateData("en",map.get("en") +"","#C71585"));
        templateMessage.addData(new WxMpTemplateData("zh",map.get("zh") +"","#C71585"));
        String beizhu = "❤";
        if(JiNianRiUtils.getLianAi() % 365 == 0){
            beizhu = "今天是恋爱" + (JiNianRiUtils.getLianAi() / 365) + "周年纪念日！";
        }
        if(JiNianRiUtils.getBirthday_Jo()  == 0){
            beizhu = "今天是生日，生日快乐呀！";
        }
        if(JiNianRiUtils.getBirthday_Hui()  == 0){
            beizhu = "今天是生日，生日快乐呀！";
        }
        templateMessage.addData(new WxMpTemplateData("beizhu",beizhu,"#FF0000"));

        try {
            System.out.println(templateMessage.toJson());
            System.out.println(wxMpService.getTemplateMsgService().sendTemplateMsg(templateMessage));
        } catch (Exception e) {
            System.out.println("推送失败：" + e.getMessage());
            e.printStackTrace();
        }
    }
}

  • 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

    在这里插入图片描述

  • 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~
