seo神器整站优化和单词

思路：监听路由变化，在路由规则中添加meta然后在组件中渲染。

import Vue from "vue"
import VueRouter from "vue-router"
Vue.use(VueRouter)
// 解决ElementUI导航栏中的vue-router在3.0版本以上重复点菜单报错问题
const originalPush = VueRouter.prototype.push
VueRouter.prototype.push = function push (location) {return originalPush.call(this, location).catch(err => err)
}const router = new VueRouter({routes:[{path:'/',redirect:'/welcome',},{path:'/home',name:'home',component:()=>import('../src/view/showIndex.vue'),meta:{title:'首页'},children:[{path:'/user',name:'user',component:()=>import('../src/view/user.vue'),meta:{title:'用户管理'}},{path:'/categroy',name:'categroy',component:()=>import('../src/view/categroy.vue'),meta:{title:'品类管理'}},{path:'/product',name:'product',component:()=>import('../src/view/product.vue'),meta:{title:'商品生产'}},{path:'/sex',name:'sex',component:()=>import('../src/view/sex.vue'),meta:{title:'角色管理'}},{path:'/welcome',name:'welcome',component:()=>import('../src/view/welcome.vue'),}]},{path:'/shang',name:'shang',component:()=>import('../src/view/showIndex.vue'),meta:{title:'商品'},children:[{path:'/user2',name:'user2',component:()=>import('../src/view/user2.vue'),meta:{title:'用户管理2'}},]},{path:'/login',name:'login',component:()=>import('../src/view/loginNews.vue')},
]
})
// 路由前置守卫
router.beforeEach((to,from,next) => {const token = localStorage.getItem("token")if(to.path ==='/login'){next()}else{if(token){next()}else{next('/login')}}})export default router
