{path: '*', redirect: '/404'}动态生成菜单

// 左侧菜单栏数据
menuItems: [
  {
    name: 'home', // 要跳转的路由名称 不是路径
    size: 18, // icon大小
    type: 'md-home', // icon类型
    text: '主页' // 文本内容
  },
  {
    text: '二级菜单',
    type: 'ios-paper',
    children: [
      {
        type: 'ios-grid',
        name: 't1',
        text: '表格'
      },
      {
        text: '三级菜单',
        type: 'ios-paper',
        children: [
          {
            type: 'ios-notifications-outline',
            name: 'msg',
            text: '查看消息'
          },
          {
            type: 'md-lock',
            name: 'password',
            text: '修改密码'
          },
          {
            type: 'md-person',
            name: 'userinfo',
            text: '基本资料',
          }
        ]
      }
    ]
  }
]



  
  

    
      
      

        
          
          
            
            {{threeItem.text}}
          
        
        
          
          {{subItem.text}}
        
      
    
    
      
      {{item.text}}
    
  


首先，要把项目所有的页面路由都列出来，再用后台返回来的数据动态匹配，能匹配上的就把路由加上，不能匹配上的就不加。


const asyncRoutes = {
  'home': {
    path: 'home',
    name: 'home',
    component: () => import('../views/Home.vue')
  },
  't1': {
    path: 't1',
    name: 't1',
    component: () => import('../views/T1.vue')
  },
  'password': {
    path: 'password',
    name: 'password',
    component: () => import('../views/Password.vue')
  },
  'msg': {
    path: 'msg',
    name: 'msg',
    component: () => import('../views/Msg.vue')
  },
  'userinfo': {
    path: 'userinfo',
    name: 'userinfo',
    component: () => import('../views/UserInfo.vue')
  }
}

// 传入后台数据 生成路由表
menusToRoutes(menusData)

// 将菜单信息转成对应的路由信息 动态添加
function menusToRoutes(data) {
  const result = []
  const children = []

  result.push({
    path: '/',
    component: () => import('../components/Index.vue'),
    children,
  })

  data.forEach(item => {
    generateRoutes(children, item)
  })

  children.push({
    path: 'error',
    name: 'error',
    component: () => import('../components/Error.vue')
  })

  // 最后添加404页面 否则会在登陆成功后跳到404页面
  result.push(
    {path: '*', redirect: '/error'},
  )

  return result
}

function generateRoutes(children, item) {
  if (item.name) {
    children.push(asyncRoutes[item.name])
  } else if (item.children) {
    item.children.forEach(e => {
      generateRoutes(children, e)
    })
  }
}

github 上，动态菜单的实现放在这个项目下的 src/components/Index.vue、src/permission.js 和 src/utils/index.js下
