使用模板方式加载菜单
lay-url=“菜单接口”
lay-headers=“将token带入请求头”，如果没有，去掉就行
在模板中使用console.log 示例： {{# console.log(1) }}
layui.data(‘layuiAdmin’).token 调用本地存储的token,token名需要和本地存储对应
json字段名不需要和这里的一样，json字段名改变，模板里面也要相应的修改
<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"
lay-headers="{'x-auth-token': layui.data('layuiAdmin').token}"
lay-done="layui.element.render('nav', 'layadmin-system-side-menu');" id="TPL_layout">
