uniapp 微信小程序 订阅消息功能实现

该网址 https://api.weixin.qq.com 上线后不可访问，调用该网址操作需在后端（ 重要！ 重要！ 重要！）

1.首先拿到的三个码

//微信公众平台
//https://mp.weixin.qq.com
const wxappid = "管理-开发管理-AppID(小程序ID)";
const wxsecret = "管理-开发管理-AppSecret(小程序密钥)";
const tmplIds = "基础功能-订阅消息-模板ID";

2.点击提示确认框，确认发送消息

//订阅确认框
const subscriptionLicense = () => {uni.requestSubscribeMessage({tmplIds: [tmplIds],success(res) {if (res[tmplIds] === "accept") {uni.showToast({title: "订阅成功",icon: "none",duration: 2000,});}},});
};

3.点击发送订阅消息

//发送订阅消息
const sendMsg = async () => {const js_code = await getJsCode();const openid = await getOpenId(js_code);const openid = "oXAk65e3CPvRP9PdyqlCvDclkSyM";const access_token = await getAccessToken();uni.request({url:"https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=" +access_token,method: "POST",data: {touser: openid,template_id: tmplIds, // 模板idpage: "pages/index/index", // 点击消息卡片跳转地址data: {// data是模板内容，属性名为模板中所给，value值是需要传递的。thing13: {value: "张三",},date5: {value: "2020年3月1日",},date2: {value: "17:45",},thing6: {value: `信用卡及分期通业绩`,},thing15: {value: `请在8:00-9:00之间完成打卡`,},},},success: (res) => {console.log(res);uni.showToast({title: "成功",icon: "none",duration: 1500,});},});
};//获取jsCode用于获取OpenId
const getJsCode = () => {return new Promise((resolve, reject) => {uni.login({success(res) {console.log("getCode", res.code);resolve(res.code);},fail: (err) => {reject(err);},});});
};//获取OpenId用于发送消息
const getOpenId = (js_code) => {return new Promise((resolve, reject) => {uni.request({url: `https://api.weixin.qq.com/sns/jscode2session`,data: {appid: wxappid,secret: wxsecret,js_code: js_code,grant_type: "authorization_code",},success: (res) => {console.log("getOpenId", res.data);resolve(res.data.openid);},fail(err) {reject(err);},});});
};// 获取access_token用于发送消息
const getAccessToken = () => {return new Promise((resolve, reject) => {uni.request({url: "https://api.weixin.qq.com/cgi-bin/token",data: {appid: wxappid,secret: wxsecret,grant_type: "client_credential",},success: (res) => {console.log("getAccessToken", res.data);resolve(res.data.access_token);},fail: (err) => {reject(err);},});});
};
