vue 登录验证引擎

1、router配置：

　　

路由元信息  
    const router = new VueRouter({
  routes: [
    {
      path: '/foo',
      component: Foo,
      children: [
        {
          path: 'bar',
          component: Bar,
          // a meta field
          meta: { requiresAuth: true }
        }
      ]
    }
  ]
})

// 父路由的配置可影响到子路由
{
      path: '/',
      name: 'index',
      redirect: './Home',
      component: r => require.ensure([], () => r(require('../components/Index')), 'Index'),
      meta: {requiresAuth: true},
      children: [
        {
          path: 'Home',
          component: r => require.ensure([], () => r(require('../components/home/Home')), 'Home')
        },
        {
          path: 'CentralizedManager',
          component: r => require.ensure([], () => r(require('../components/centralizedmanager/CentralizedManager')), 'CentralizedManager')
        },
        {
          path: 'Patrol',
          component: r => require.ensure([], () => r(require('../components/patrol/Patrol')), 'Patrol')
        },
         ]
}

router.beforeEach((to, from, next) => {
　　// 父路由的配置可影响到子路由
  if (to.matched.some(record => record.meta.requiresAuth)) {
    // this route requires auth, check if logged in
    // if not, redirect to login page.
    if (!homeService.loggedIn()) {
      next('/Login')
    } else {
      next()
    }
  } else {
    next() // 确保一定要调用 next()
  }
})

2、homeService :

　　

loggedIn(){
    return !!sessionStorage.getItem('accessToken');
  },

 3、登录

　　

this.$http.post(url,data).then((response) => {

    if(result.code==100){
        sessionStorage.setItem('accessToken', result.data.access_token);
        sessionStorage.setItem('userName', result.data.username);
        this.$notify({title: '成功',message: '登陆成功',type: 'success'});
        this.$router.push('home')
    }
 }
