首先讲两个注意事项
1、小程序和微信公众号的用户openid是不同的。
2、小程序需要用户手动授权订阅消息通知。
关于小程序和公众号AppID和AppSecret的获取可以自行百度一下，挺简单的。
小程序订阅消息
1.1 在后台选中自己需要的模板和相应的字段，注意不同的字段字符长度和格式的问题。
参考文档：subscribeMessage.send | 微信开放文档
【订阅消息参数值内容限制说明】
1.2 小程序授权按钮
<button class="btn" bindtap="onSubscribe" hover-class="btn-hover">
订阅挂号成功提醒
</button>
//开启消息通知
onSubscribe: function(e) {
// 消息推送
wx.requestSubscribeMessage({
tmplIds: ['daPvT7nLnOY***************F_A9VCBI'], //你的模板id
success(res) {
console.log('授权成功', res)
},
fail(res) {
console.log('授权失败', res)
}
})
},1.3 我这里用的HTTPS发送，代码是php
<?php
/*

public function actionSubmessage($openid = null){
//配置appid
$appid = "";
//配置appscret
$secret = "";
$url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$secret;
//获取access_token
$access_token = $this->geturl($url)["access_token"];
$urlz="https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=".$access_token;
//模板id
$template_id = "daPvT7nLnO*********************A9VCBI";
$data = [] ;
//接收者（用户）的 openid
$data['touser'] = $openid;
//所需下发的订阅模板id
$data['template_id'] = $template_id ;
//点击模板卡片后的跳转页面，仅限本小程序内的页面。支持带参数,（示例index?foo=bar）。该字段不填则模板无跳转。
$data['page'] = "pages/index/index" ;
//模板内容 phrase date thing 这些类型有字符长短要求，注意看文档
$data['data'] = [
"phrase2" => [
'value' => '测试'
],
"phrase6" => [
'value' => '就诊李主任'
],
"date14" => [
'value' => '2022年06月11日'
],
"date8" => [
'value'=>'8:30 ~ 17:00'
],
'thing18'=>[
'value'=> '呼吸内科'
]
];
//跳转小程序类型：developer为开发版；trial为体验版；formal为正式版；默认为正式版
$data['miniprogram_state'] = 'developer';
var_dump($this->posturl($urlz,$data));
}

公众号模板消息推送?
2.1 微信公众号开启模板消息推送
?2.2 这个前端没啥特别的，直接上后端代码，用的tp6框架，可以根据实际情况自己改
