微信小程序订阅消息功能

小程序订阅消息

功能介绍

消息能力是小程序能力中的重要组成，我们为开发者提供了订阅消息能力，以便实现服务的闭环和更优的体验。

• 订阅消息推送位置：服务通知
• 订阅消息下发条件：用户自主订阅
• 订阅消息卡片跳转能力：点击查看详情可跳转至该小程序的页面

使用说明

步骤一：获取模板 ID
步骤二：获取下发权限
详见小程序端消息订阅接口 wx.requestSubscribeMessage
步骤三：调用接口下发订阅消息
详见服务端消息发送接口 subscribeMessage.send

uni.requestSubscribeMessage({
  tmplIds: [''],
  success (res) { }
})

• wx.requestSubscribeMessage(Object object)
• subscribeMessage.send

<form :report-submit="true" @submit="createOrder" style="display: flex; justify-content: center;">
</form>

用户需要点击“总是保持以上，不再询问”，才可以获取到getSetting返回的用户授权信息

requestMsg(){
 return new Promise((resolve, reject) => {
 wx.requestSubscribeMessage({
 tmplIds: [" -ZwAFL- "],
 success: (res) => {
  if (res[' -ZwAFL- '] === 'accept'){
  wx.showToast({
  title: '订阅OK！',
  duration: 1000,
  success(data) {
  //成功
  resolve()
  }
  })
  }
 },
 fail(err) {
  //失败
  console.error(err);
  reject()
 }
 })
 })
 }

openMsg() {
    var that = this
    // 获取用户的当前设置，判断是否点击了“总是保持以上，不在询问”
    wx.getSetting({
        withSubscriptions:true,  // 是否获取用户订阅消息的订阅状态，默认false不返回
       success(res) {
          if(res.authSetting['scope.subscribeMessage']) { // 用户点击了“总是保持以上，不再询问”
             uni.openSetting({ // 打开设置页
               success(res) {
                 console.log(res.authSetting)
               }
             });
          }else { // 用户没有点击“总是保持以上，不再询问”则每次都会调起订阅消息
             var templateid = that.setting.templateid.map(item => item.tempid)
             uni.requestSubscribeMessage({
               tmplIds: templateid,
