Laravel Vue不会返回元标记

Question

我在vue-router中提供了meta，但是在HTML中却没有返回

代码

router sample

{
            path: '/',
            name: 'home',
            component: Home,
            meta: {
                title: 'Home Page - Welcome',
                metaTags: [
                  {
                    name: 'description',
                    content: 'The home page of our example app.'
                  },
                  {
                    property: 'og:description',
                    content: 'The home page of our example app.'
                  }
                ]
            }
        },
        {
            path: '/login',
            name: 'login',
            component: Login,
            meta: { title: 'Login' }
        },

beforeeach

router.beforeEach((to, from, next) => {
    if (to.matched.some(record => record.meta.requiresAuth)) {
        if (localStorage.getItem('myApp.jwt') == null) {
            next({
                path: '/login',
                params: { nextUrl: to.fullPath }
            })
        } else {
            let user = JSON.parse(localStorage.getItem('myApp.user'))
            if (to.matched.some(record => record.meta.is_admin)) {
                if (user.is_admin == 1) {
                    next()
                }
                else {
                    next({ name: 'userboard' })
                }
            }
            next()
        }
    } else {
        next()
    }
});

这是我的页面标题的样子：

，浏览器中也没有元符号：

问题

1. 如何解决此问题？
2. 如何获取动态页面（如单个帖子组件）的标题？
