小程序云函数实现发送模板消息

const cloud = require('wx-server-sdk');
cloud.init();

exports.main = async (event, context) => {
  const wxContext = cloud.getWXContext();
  try {
    let page_url =
      '/pages/sure_buy/sure_buy?device=2&out_trade_no=' +
      event.out_trade_no;
    if (event.curriculum_id != undefined) {
      page_url += '&curriculum_id=' + event.curriculum_id;
    }
    const result = await cloud.openapi.templateMessage.send({
      touser: wxContext.OPENID,
      page: page_url,
      data: {
        keyword1: {
          value: event.order_time
        },
        keyword2: {
          value: event.out_trade_no//订单编号
        },
        keyword3: {
          value: event.name//支付时间
        },

        },

      formId: event.form_id//支付统一下单时的prepay_id
    });
