Vue 动态路由的实现详情

//src/router/index.js
import Router from 'vue-router'
Vue.use(Router)
const Routes = [
    {
        path:'/',
        component:Login,
        meta: {
            title: '登录页'
        }
    },
    {
        path:'/Home',
        component:Home,
        meta: {
            title: 'Home主页'
        }
    }
]
const Routers = new Router({
    routes: Routes
})
export default Routers;

//stc/router/index.js
const defaultRoutes = [
//...这默认路由就是上面代码内的登录页/404页面...
]
const allRouters = [//这里就是全部动态路由
    {
        path:'/UserList',
        component:UserList,
        meta: {
            title: '人员管理'
        }
    },
    {
        path:'/PwdList',
        component:PwdList,
        meta: {
            title: '密码管理'
        }
    }
]
const Routers = new Router({
    routes: defaultRoutes//默认渲染 -> 默认路由
})
export default Routers;

Routers.beforeEach((to,from,next) => {
    if(to.path != '/' && !store.state.isLogin) {
        //跳转的不是首页 同时 用户还未登陆
        //这个判断，我们就可以基本判定用户是在做登陆时候的跳转
        //↓拿到登陆时，接口返回的路由数组（vuex内）,大致是这样的
        let resRouterArr = [
            {
                routeName: '人员管理',
                children: [
                    {
                        routeName: '销售管理',
                        ...
                    },
                    {

                        ...
                    }
                ]
            }
        ]
        let routerArr = []
        resRouterArr.forEach(item => {
            allRouters.forEach(all => {
                if(item.routeName == all.routeName) {
                    //拿到本地路由对象
                    let obj = JSON.parse(JSON.stringify(all))
                    let childrenRouter = []
                    if(item.children && item.children.length > 0) {
                        item.children.forEach(childItem => {
                            all.children.forEach(allItem => {
                                if(childItem.routeName == allItem.routerName) {
                                    childrenRouter.push(allItem)
                                }
                            })

                }
            })
        })
        Routers.addroutes(routerArr)//addroutes为添加路由数组的方法
        store.commit('domRouteTree',rousterArr)//存储进vuex，之后页面左右路由列表渲染使用
        next({...to,replace:true})//进行路由跳转
    } else {
        next()
    }
