订阅模板信息如上图

测试用户已允许获取订阅消息

云函数代码如下

//config 
{
 "permissions": {
    "openapi": [
      "templateMessage.send"
    ]
  }
}
//测试发布订阅消息云函数
const cloud = require('wx-server-sdk')
cloud.init({
  env: 'ENV-ID',
})

// 云函数入口函数
exports.main = async (event, context) => {
  try {
    const result = await cloud.openapi.subscribeMessage.send({
      touser: 'oTELJ5apZ7CE0663ONOemmq91UHc', // 订阅者的openid
      page: 'pages/taskList/taskList',
      data: {
        thing10: {
          value: 'test'
        },
        thing2: {
          value: 'test'
        }
      },
    })
    console.log(result)
    return result
  } catch (err) {
    console.log(err)
    return err
  }
}
