/**
 * 对后台请求的地址的封装，URL格式如下：
 * 模块名_实体名_操作
 */
export default 
    ‘SERVER‘: ‘http://localhost:8080/T216_SSH‘, //服务器

    ‘SYSTEM_USER_DOREG‘: ‘/vue/userAction_reg.action‘, //用户注册
    ‘SYSTEM_MENU_TREE‘: ‘/vue/treeNodeAction.action‘, //左侧树形菜单加载
    ‘SYSTEM_ARTICLE_LIST‘: ‘/vue/articleAction_list.action‘, //文章列表
    ‘SYSTEM_ARTICLE_ADD‘: ‘/vue/articleAction_add.action‘, //文章新增
    ‘SYSTEM_ARTICLE_EDIT‘: ‘/vue/articleAction_edit.action‘, //文章修改
    ‘SYSTEM_ARTICLE_DEL‘: ‘/vue/articleAction_del.action‘, //文章删除
    ‘SYSTEM_USER_GETASYNCDATA‘: ‘/vue/userAction_getAsyncData.action‘, //vuex中的异步加载数据
    ‘getFullPath‘: k =>  //获得请求的完整地址，用于mockjs测试时使用
        return this.SERVER + this[k];
    

 

LeftAside.vue(加载动态数)

注1：要实现路由跳转，先要在el-menu标签上添加router属性，然后只要在每个el-menu-item标签内
的index属性设置一下url即可实现点击el-menu-item实现路由跳转。
注2：导航当前项，在el-menu标签中绑定 :default-active="$route.path",注意是绑定属性，
不要忘了加“:”,当$route.path等于el-menu-item标签中的index属性值时则该item为当前项。

        <!-- <el-menu default-active="2" :collapse="collapsed" collapse-transition router :default-active="$route.path" unique-opened class="el-menu-vertical-demo" background-color="#334157" text-color="#fff" active-text-color="#ffd04b"> -->
