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

<template><view class="content"><image class="logo" src="/static/guide1.png"></image><view class="text-area"><button class="title" @click="btnclick">订阅消息</button></view></view>
</template><script setup>import { ref } from 'vue';import { parseTime } from "../../utils/ruoyi";const show = ref(true)const showModal = ref(false);function close() {show.value = false}function acc() {uni.showModal({title: '通知权限',content: '请授权通知管理，用于给您及时传达消息',success: function(res) {if (res.confirm) {console.log('点击了确认')btnclick()} else {console.log('点击了取消')}}})}function btnclick() {if (wx.requestSubscribeMessage) {wx.requestSubscribeMessage({tmplIds: ['模板Id'],success(res) {if (res['模板Id'] == 'accept') {console.log('用户订阅成功');btnSubscription()} else if (res['模板Id'] == 'reject') {console.log('用户拒绝订阅');}},fail(err) {console.error('订阅请求失败:', err);}});} else {console.error('此平台不支持订阅');}}async function btnSubscription() {let code = null;let accessToken = null;let openid = null;let time = parseTime(new Date())try {code = await getLoginCode();if (code) {openid = await requestOpenID(code);console.log('User OpenID:', openid);}accessToken = await requestAccessToken();console.log('Access Token:', accessToken);} catch (error) {console.error('errorerror', error);}uni.request({url: 'https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=' +accessToken,method: 'POST',data: {touser: openid,template_id: '模板Id',page: "pages/index/index",data: {thing1: {value: '测试小程序订阅通知'},thing2: {value: '该服务是测试通知，请务必订阅'},name3: {value: '测试一号'},date4: {value: time},thing5: {value: '测试'}}},success: (res) => {console.log("发送成功", res);}})}const getLoginCode = () => {return new Promise((resolve, reject) => {wx.login({success: (res) => {console.log('res.code', res.code);if (res.code) {resolve(res.code);} else {reject('Failed to obtain login code');}},fail: (err) => {reject(err);},});});};const requestOpenID = (code) => {return new Promise((resolve, reject) => {wx.request({url: 'https://api.weixin.qq.com/sns/jscode2session',data: {appid: '小程序AppId',secret: '小程序密钥',js_code: code,grant_type: 'authorization_code',},success: (res) => {console.log('resres', res);if (res.data.openid) {resolve(res.data.openid);} else {reject('Failed to obtain user OpenID');}},fail: (err) => {reject(err);},});});};const requestAccessToken = () => {return new Promise((resolve, reject) => {wx.request({url: 'https://api.weixin.qq.com/cgi-bin/token',data: {appid: '小程序AppId',secret: '小程序密钥',grant_type: 'client_credential',},success: (res) => {if (res.data.access_token) {resolve(res.data.access_token);} else {reject('Failed to obtain Access Token');}},fail: (err) => {reject(err);},});});};acc()
</script><style>.content {display: flex;flex-direction: column;align-items: center;justify-content: center;}.logo {height: 200rpx;width: 600rpx;margin-top: 100rpx;margin-left: auto;margin-right: auto;margin-bottom: 50rpx;}.text-area {display: flex;justify-content: center;}.title {font-size: 36rpx;color: #8f8f94;}
