最近项目迭代完成最后一版需要完成清尾工作。

这里需要完成菜单的权限控制，最开始完成这项工作是吧所有的菜单都写到home模块，然后用v-if来判断菜单的显示。

看Vue Router的API文档发现

router.addRoutes

函数签名：

router.addRoutes(routes: Array<RouteConfig>)

动态添加更多的路由规则。参数必须是一个符合 routes 选项要求的数组。

这个命令可以实现我的想法，多的不说直接上代码。（我把他直接放到权限接口请求的回调里简单粗暴）

let routes = [
          {
            path: "/",
            component: Home,
            name: "首页",
            iconCls: "#icon-shouye", //图标样式class
            children: [
              {
                path: "/main",
                component: main,
                name: "我的易到",
                hidden: false
              }
            ]
          },
          {
            path: "/",
            component: Home,
            name: "人员",
            iconCls: "#icon-renyuanxiaozu",
            children: [

                hidden: user_info.isTopCorpUser ? false : true

              {

          {
            path: "/404",

            path: "*",
            hidden: true,
            redirect: { path: "/404" }
          }
        ];
        this.$router.options.routes = routes;
        this.$router.addRoutes(routes);

其中最主要的是

this.$router.options.routes = routes;

如果没有这一段就不会生效这是因为，router.options.routes 不是响应式的。
