vue-router中需要注意用的几个知识点

1.meta作为route对象的属性，可以自定义值。

如在routes.js中，常把是meta的authorRequired的值否需要登录验证的标志；在router对象的beforeEach中验证

import Vue from 'vue';
import Router from 'vue-router';

import routes from './routes';
import store from '@/store'

Vue.use(Router);
const router = new Router({
  mode: 'history',
  routes
})

router.beforeEach((to, from, next)=>{
  if(to.matched.some(record=>record.meta.requiresAuth)){ //需要验证权限
    const status = store.getters['userLogin/getStatus']; 
    const topath = to.fullPath;
    if(status == 'logined'){//已登陆
      next()
     }else if(status == 'isLogining'){//正在登录，转到正在登录页
      // next({name:'loading', query: {topath}})
      next({name:'login', query: {topath}})

     }else{//未登录
      alert('请先登录1111')
      next({name:'login',
      query:{topath}
    })
    }
  }
  next()
})


export default router;
