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

import org.apache.http.httpentity; import org.apache.http.client.methods.closeablehttpresponse; import org.apache.http.client.methods.httpget; import org.apache.http.client.methods.httppost; import org.apache.http.conn.ssl.noophostnameverifier; import org.apache.http.conn.ssl.sslconnectionsocketfactory; import org.apache.http.conn.ssl.trustselfsignedstrategy; import org.apache.http.entity.stringentity; import org.apache.http.impl.client.closeablehttpclient; import org.apache.http.impl.client.httpclients; import org.apache.http.ssl.sslcontexts; import org.apache.http.util.entityutils; import java.io.ioexception; /** * @author lrx * @description: todo * @date 2021/3/9 9:50 */ public class httpclientutils { //http协议get请求 public static string httpget(string url) throws ioexception { //初始化httpclient closeablehttpclient httpclient = httpclients.createdefault(); //创建httpget httpget httpget = new httpget(url); //发起请求，获取response对象 closeablehttpresponse response = httpclient.execute(httpget); //获取请求状态码 //response.getstatusline().getstatuscode(); //获取返回数据实体对象 httpentity entity = response.getentity(); //转为字符串 string result = entityutils.tostring(entity, "utf-8"); return result; } //http协议post请求 public static string httppost(string url, string json) throws exception { //初始httpclient closeablehttpclient httpclient = httpclients.createdefault(); //创建post对象 httppost httppost = new httppost(url); //设置content-type /* httppost.setheader("content-type", "application/x-www-form-urlencoded");*/ stringentity se = new stringentity(json,"utf-8"); se.setcontenttype(odo 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 = ""恰卡编程网; //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 qqmaphttp://www.cppcns.com.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()); } } }

5.推送结果
