短信鏈接帶參數(shù)跳轉(zhuǎn)小程序

創(chuàng)建云函數(shù)

// 云函數(shù)入口文件
const cloud = require('wx-server-sdk')

cloud.init()

// 云函數(shù)入口函數(shù)
exports.main = async (event, context) => {
  const wxContext = cloud.getWXContext()

  switch (event.action) {
    case 'getUrlScheme': {
      return getUrlScheme(event.id)  //event.id可以取到index.html傳來的id參數(shù)
    }
  }

  return 'action not found'
}

async function getUrlScheme(id) {
  return cloud.openapi.urlscheme.generate({
    jumpWxa: {
      path: '/page/activity_detail/index', // <!-- replace -->
      query: 'id='+id,
    },
    // 如果想不過期則置為 false，并可以存到數(shù)據(jù)庫
    isExpire: false,
    // 一分鐘有效期
    expireTime: parseInt(Date.now() / 1000 + 60),
  })
}
