  userInfo: {},
  hasUserInfo: false,
  canIUse: wx.canIUse('button.open-type.getUserInfo')
 },
 //事件处理函数
 goLogs: function() {
  wx.navigateTo({
   url: '/pages/logs/logs'
  })
 },
 onLoad: function (options) {
  console.log(options)
  if (options.share_query){
   wx.showLoading({
    title: '我是从分享页面进入的',
   })

   setTimeout(function () {
    wx.hideLoading()
    wx.navigateTo({

  //判断是否分享进入
