let that = this
    wx.cloud.callFunction({
      name: "loginopenid"
    }).then(res => {
      wx.setStorageSync('openid', res.result.openid)
      that.setData({
        Storage_user_info: wx.getStorageSync('Storage_user_info')
      })
      if (that.data.Storage_user_info.Open_id == res.result.openid) {
        console.log("获取缓存OPENID", that.data.Storage_user_info.Open_id)       
？？？？这个位置打印OPENID是正常的
        that.setData({
          img_url: that.data.Storage_user_info.head_sculpture

        })

    })
    db.collection("shop_openId").get().then(res => {
      var a = res.data[0].shop_openId
      var b = wx.getStorageSync('Storage_user_info').Open_id              
？？？？？这里如果用that.data.Storage_user_info.Open_id就提示变量b未定义，只能用缓存数据
      if (a == b) {                                                      
        that.setData({
          Show_order_management_buttons: true
        })
      }
    })
？？？？？这是什么原因啊
