近期在搞一個會議健康申報系統時，要搞一個後臺，用vZGOok到了-element-admin模板，使用的是PanJianChen(原始碼地址：https://.com/PanJiaChen/vue-admin-template)

第一步：當前是下載原始碼了，下載地址：https://github.com/PanJiaChen/vue-admin-template

第二步：修改登入頁面，登入介面（/store/modules/admin./login()），根據實際情況修改使用者資訊介面(/store/modules/admin.js/getInfo())

第三步：修改許可權路由

1.刪減路由檔案中的配置，export const constantRoutes保留基本的/login、/404

2.動態路由清空，export const asyncRoutes=[]

3./store/modules/permission.js下定義生成路由方法

/**
 * 後臺查詢的選單資料拼裝成路由格式的資料
 * @param routes
 */
export function generaMenu(routes,data) {
 
    data.forEach(item => {
        let menu = {
            path: item.url,children: [],name: 'menu_' + item.id,meta: { title: item.name,id: item.id,icon:item.icon}
        }
        // console.log(item.url.indexOf('dashboard'))
 
        // console.log(item.children)
        if (item.children) {
            // console.log(item.children.length)
            if (item.children.length > 0) {
                menu.redirect = item.children[0].url
                menu.component = Layout
            } else {
                // menu.component = () => import(`@/views${item.url}/index`)
                menu.component = () => Promise.resolve(require(`@/views${item.url}`).default)
 
            }
            if (item.url && item.url.indexOf('dashboard') != -1) {
                menu = {
                    path: '/',component: Layout,redirect: '/dashboard',children: [{
                        path: 'dashboard',name: 'Dashboard',component: () => import('@/views/dashboard/index'),meta: { title: '控制檯',icon: 'dashboard' }
                    }]
                }
            }
            generaMenu(menu.children,item.children)
        } else {
            console.log('沒有children')
        }
        routes.push(menu)
    })
}

actions中根據後臺的介面載入動態路由

actions: {
        GenerateRoutes({ commit },data) {
            return new Promise(resolve => {
 
                const loadMenuData = []
                getAuthMenu().then(res => {
                    let data = res.data
                    console.log('menu=>',data)
                    console.log('asyncRoutes=>>',asyncRoutes)
                    let newRoutes = []//此處清空之前的路由
                    Object.assign(loadMenuData,data)
                    generaMenu(newRoutes,loadMenuData)
                    newRoutes.push({ path: '*',redirect: '/404',hidden: true })
                    let accessedRouters = newRoutes || []
                    console.log('accessedRouters',accessedRouters)
                    commit('SET_ROUTERS',accessedRouters)
                    resolve()
                })
 
            })
        },reset_routers({ commit }) {
            return new Promise(resolve => {
                commit('RESET_ROUTERS')
                resolve()
            })
        }
    }

第四步、在/permission.js中新增動態路由

router.beforeEach(async (to,from,next) => {
    // start progress bar
    NProgress.start()
 
    // set page title
    document.title = getPageTitle(to.meta.title)
 
    // determine whether the user has logged in
    const hasToken = getToken()
 
    if (hasToken) {
        if (to.path === '/login') {
            // if is logged in,redirect to the home page
            next({ path: '/' })
            NProgress.done()
        } else {
            const hasGetUserInfo = store.getters.name
            if (hasGetUserInfo) {
                next()
            } else {
                try {
                    // get user info
                    await store.dispatch('admin/getInfo')
 
                    store.dispatch('GenerateRoutes',{}).then(() => { // 生成可訪問的路由表
                        router.addRoutes(store.getters.addRouters) // 動態新增可訪問路由表
                        console.log('to=',store.getters.addRouters)
                        next({ ...to,replace: true }) // hack方法 確保addRoutes已完成,set the replachttp://www.cppcns.come: true so the navigation will not leave a history record
                        NProgress.done()
                    })
 
                    // next()
                } catch (error) {
                    // remove token and go to login page to re-login
                    await store.dispatch('admin/resetToken')
                www.cppcns.com    Message.error(error || 'Has Error')
                    next(`/login?redirect=${to.path}`)
                    NProgress.done()
                }
            }
        }
    } else {
        /* has no token*/
 
        if (whiteList.indexOf(to.path) !== -1) {
            // in the free login whitelist,go directly
            next()
        } else {
            // other pages that do not have permissiowww.cppcns.comn to access are redirected to the login page.
            next(`/login?redirect=${to.path}`)
            NProgress.done()
        }
    }
})

然後你就可心情地玩了。
