SpringBoot小程序推送信息怎么实现

这篇文章主要介绍了SpringBoot小程序推送信息怎么实现的相关知识，内容详细易懂，操作简单快捷，具有一定借鉴价值，相信大家阅读完这篇SpringBoot小程序推送信息怎么实现文章都会有所收获，下面我们一起来看看吧。

1.小程序推送信息列如我们去餐厅等位有预约提醒，剩余桌数

首先申请一个小程序，微信开放平台：小程序

2.申请小程序信息，申请信息模板

appid

AppSecret

3.根据开发文档开发

subscribeMessage.send | 微信开放文档

4.代码如下：

引入依赖

         org.apache.httpcomponents        httpclient        4.5.2    

先准备一个HTTP工具类Z

测试代码

import com.alibaba.fastjson.JSONObject; import java.io.IOException;import java.util.Date;import java.util.HashMap;import java.util.Map; /** * @author lrx * @description: TODO  小程序推送 * @date 2022/4/11 13:32 */public class TestXCXMain {    public static void main(String[] args) throws Exception {        String appid = "";  //appid        String secret = "";  //secret         //登录链接获取token        String loginUrl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" + appid + "&secret=" + secret;        Map payloadMap = JSONObject.parseObject(HttpClientUtils.httpGet(loginUrl));        String token = null;        if (payloadMap.containsKey("access_token")) {            token = payloadMap.get("access_token").toString();        }        System.out.println("获取token" + token);        Map qqMap = new HashMap();        qqMap.put("touser", "openid");  //要推送的openid        qqMap.put("template_id", "");   //信息模板id        qqMap.put("page", "index");        qqMap.put("miniprogram_state", "developer");        qqMap.put("lang", "zh_CN");        //封装信息        Map dataMap = new HashMap();        Map valueMap1 = new HashMap();        valueMap1.put("value", "成功");        Map valueMap2 = new HashMap();        valueMap2.put("value", "成功");        dataMap.put("thing3", valueMap1);        dataMap.put("thing1", valueMap2);        qqMap.put("data", dataMap);        //发送        Map payloadMapData = JSONObject.parseObject(HttpClientUtils.httpPost("https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token="+token,JSONObject.toJSONString(qqMap)));        if (payloadMapData.containsKey("errCode")) {            System.out.println("返回code码："+payloadMapData.get("errCode").toString());        }    }}
