[移动开发]前端埋点 后端提供js 的一次记录ios-url始终是第一次进入的urlios路径不变，清空上一个页面正在请求的内容

• main.js

window._tcloud_trackLog = (a) => {
  try {
    // eslint-disable-next-line no-undef
    if (_zyat && _zyat.push) _zyat.push(a)
  } catch { }
}

• permission.js

router.afterEach((to, from) => {
  addInput()
})

function addInput () {
  if (store.state.userInfo.loginName) {
    log = false
    var uid = document.querySelector('#uid')
    if (!uid) {
      uid = document.createElement('input')
    }
    uid.id = 'uid'
    uid.setAttribute('value', store.state.userInfo.loginName)
    uid.setAttribute('type', 'hidden')
    document.body.append(uid)

    var slist = document.getElementsByTagName('script')
    for (var i = 0; i < slist.length; i++) {
      if (slist[i].src.indexOf('https://productjs.71360.com') > -1) {
        slist[i].remove()
      }
    }

    loadScript('https://productjs.71360.com/statistics.js')
  } else {
    setTimeout(() => {
      addInput()
    }, 100)
  }
}


function loadScript (url, callback) {
  var s = document.createElement('script')
  s.type = 'text/javascript'
  if (s.readyState) {
    s.onreadystatechange = function () { // 兼容IE
      if (s.readyState === 'complete' || s.readyState === 'loaded') {
        if (callback) { callback() }
      }
    }
  } else {
    s.onload = function () { // safari chrome opera firefox
      if (callback) { callback() }
    }
  }
  s.src = url
  document.head.appendChild(s)
}

// eslint-disable-next-line no-unused-vars
let log = false

router.beforeEach((to, from, next) => {
  localStorage.setItem('ttotalFrom', window.location.origin + from.fullPath)
  localStorage.setItem('ttotalTo', window.location.origin + to.fullPath)
  log = true
})

• 使用

_tcloud_trackLog(['trackEvent', 'scrm_rootqrcode', 'click', 'rootqrcode_index'])

• 一些其他的

	router.beforeEach((to, from, next) => {
  // IOS 鉴权
  // 1，ios的微信在vue使用history模式时，当前的“地址栏”的url不是真实的当前页面的URL
  // 2，当用户在操作页面的时候，无论进了几个页面，跳转到哪里，当前页面是什么，当前地址栏的url始终是第一次进入的url。
  if (window.__wxjs_is_wkwebview) { // IOS
    if (window.entryUrl == '' || window.entryUrl == undefined) {
      var url = process.env.VUE_APP_OPEN_H5 +
        to.fullPath
      window.entryUrl = url
    }
  } else { // 安卓
    window.entryUrl = process.env.VUE_APP_OPEN_H5 +
      to.fullPath
  }
  localStorage.setItem('ttotalFrom', window.location.origin + from.fullPath)
  localStorage.setItem('ttotalTo', window.location.origin + to.fullPath)
  log = true
  if (dd.env.platform !== 'notInDingTalk' && !getToken()) {
    getDDCookie(to, from, next)
  } else {
    routerJump(to, from, next)
  }

  // 2.进入路由钩子拦截时候， 路由跳转之前，清空（终止）上一个页面正在请求的内容
  if (window._axiosPromiseArr.length > 0) {
    window._axiosPromiseArr.forEach((item) => {
      item()
    })
    window._axiosPromiseArr = []
  }
})
