使用模板方式加載菜單

lay-url=“菜單接口”

lay-headers=“將token帶入請求頭”，如果沒有，去掉就行

在模板中使用console.log 示例： {{# console.log(1) }}

layui.data(‘layuiAdmin’).token 調(diào)用本地存儲的token,token名需要和本地存儲對應

json字段名不需要和這里的一樣，json字段名改變，模板里面也要相應的修改

<div class="layui-side layui-side-menu">
  <div class="layui-side-scroll">
    <script type="text/html" template lay-url="https://easy-mock.com/mock/5c131015dada7b27ac3a5c36/titi/treemenu"
