formId 在安卓系统是纯数字，在IOS系统是一串加密字符，如图：

发送模板消息（服务通知）效果图：

前端

wxml

<form bindsubmit="submitForm" report-submit >
  <button form-type="submit">发送</button>
</form>

js

  submitForm(e){
    console.log(e.detail.formId);
    var formId = e.detail.formId == 'the formId is a mock one' ? 1546946903765 : e.detail.formId;
    util.request('http://localhost/sendTemplateMessage.php', 'get', { formId}, '', function (res) {
      console.log('sendTemplateMessage:',res)
    })
  },

后端php

<?php
 	header("Content-Type:text/html;charset=utf8"); 
    header("Access-Control-Allow-Origin: *"); //解决跨域
    header('Access-Control-Allow-Methods:GET');// 响应类型  
    header('Access-Control-Allow-Headers:*'); // 响应头设置 
    $link=mysql_connect("localhost","root","root"); 
    mysql_select_db("6677onechat", $link); //选择数据库
    mysql_query("SET NAMES utf8");//解决中文乱码问题
    
    //$openid = $_GET['openid'];
    $form_id =getFormId();

番外笔记，可以忽略

php,  查找表里面该openid 的formid，前端传发送信息的昵称和信息，然后通过模板消息发送给对方。
