Vue让router-view默认显示任意页面

场景：一个home页面，点击左边的菜单栏，右边显示页面，因此都知道在右边放一个router-view然后配置路由即可。

然而问题出现在：重新打开的时候，默认是白色空的。

那么解决办法是：

在router管理的index.js中
加上 redirect:'/xxxx'

       {
          path: "/xcgk",
          name: "xcgk",
          component: require("@/views/xcgk/xcgk").default,
          redirect:'/assessment' ,

          children: [
            {
              path: '/Orderissuance',
              name: '指令下达',
              component: Orderissuance,

            }, {
              path: '/taskmanagement',
              name: '任务管理',
              component: taskmanagement,
            }, {
              path: '/Officialnotice',
              name: '工作动态',
              component: Officialnotice,
            }, {
              path: '/Workdynamics',
              name: '公文通知',
              component: Workdynamics,
            }, {
              path: '/assessment',
              name: '统计考核',
              component: assessment,
            }, {
              path: '/OffciaAdd',
              name: "OffciaAdd",
              component: require("@/views/xcgk/rwgl/OffciaAdd").default,
 },]
        },
