前言
在发送模板消息之前我们要首先搞清楚微信小程序的逻辑是什么,这只是前端的一个demo实现,建议大家在后端处理,前端具体实现:如下图
1.获取小程序Id和密钥
我们注册完微信小程序后,可以在开发设置中看到以下内容,注意,密钥只会在生成时显示
2.创建模板消息,拿到模板id
在右侧详情中我们可以看到具体要传输的数据对象,注意一一对应
3.发送模板消息-完整代码
javascript
<template>
<view class="content">
<image class="logo" src="/static/guide1.png"></image>
<view class="text-area">

</view>
</template>
