将动态显示的路由写在asyncRoutes 中并添加 roles ，例如meta: { roles: [‘admin’] },

• 在store/modulds目录下添加permission.js

import { asyncRoutes, constantRoutes } from ‘@/router’

/**

• Use meta.role to determine if the current user has permission
• @param roles
• @param route

*/

function hasPermission(roles, route) {

if (route.meta && route.meta.roles) {

return roles.some(role => route.meta.roles.includes(role))

} else {

return true

}

}

/**

• Filter asynchronous routing tables by recursion
• @param routes asyncRoutes
• @param roles

*/

export function filterAsyncRoutes(routes, roles) {

const res = []

routes.forEach(route => {

const tmp = { …route }

if (hasPermission(roles, tmp)) {

if (tmp.children) {

tmp.children = filterAsyncRoutes(tmp.children, roles)

}

res.push(tmp)

}

})

return res

}

const state = {

routes: [],

addRoutes: []

}

const mutations = {

SET_ROUTES: (state, routes) => {

state.addRoutes = routes

state.routes = constantRoutes.concat(routes)

}

}

const actions = {

generateRoutes({ commit }, roles) {

return new Promise(resolve => {

const accessedRoutes = filterAsyncRoutes(asyncRoutes, roles)

commit(‘SET_ROUTES’, accessedRoutes)

resolve(accessedRoutes)

})

}

}

export default {

namespaced: true,

state,

mutations,

actions

}

• 修改store/modulds/user.js

import { login, logout, getInfo } from ‘@/api/user’

import { getToken, setToken, removeToken } from ‘@/utils/auth’

import { resetRouter } from ‘@/router’

const getDefaultState = () => {

return {

token: getToken(),

name: ‘’,

avatar: ‘’,

roles: []

}

}

const state = getDefaultState()

const mutations = {

RESET_STATE: (state) => {

Object.assign(state, getDefaultState())

},

SET_TOKEN: (state, token) => {

state.token = token

},

SET_NAME: (state, name) => {

state.name = name

},

SET_AVATAR: (state, avatar) => {

state.avatar = avatar

},

SET_ROLES: (state, roles) => {

state.roles = roles

}

}

const actions = {

// user login

login({ commit }, userInfo) {

const { username, password } = userInfo

return new Promise((resolve, reject) => {

login({ username: username.trim(), password: password }).then(response => {

const { data } = response

commit(‘SET_TOKEN’, data.token)

setToken(data.token)

resolve()

}).catch(error => {

reject(error)

})

})

},

// get user info

getInfo({ commit, state }) {

return new Promise((resolve, reject) => {

getInfo(state.token).then(response => {

const { data } = response

if (!data) {

return reject(‘验证失败，请重新登录’)

}

const {roles, name, avatar } = data

commit(‘SET_ROLES’, roles)

commit(‘SET_NAME’, name)

commit(‘SET_AVATAR’, avatar)

resolve(data)

}).catch(error => {

reject(error)

})

})

},

// user logout

logout({ commit, state }) {

return new Promise((resolve, reject) => {

logout(state.token).then(() => {

removeToken() // must remove token first

resetRouter()

commit(‘RESET_STATE’)

commit(‘SET_ROLES’, [])

resolve()

}).catch(error => {

reject(error)

})

})

},

// remove token

resetToken({ commit }) {

return new Promise(resolve => {

removeToken() // must remove token first

commit(‘RESET_STATE’)

commit(‘SET_ROLES’, [])

resolve()

})

}

}

export default {

namespaced: true,

state,

mutations,

actions

}

添加roles: [] 保存权限列表 ，添加内容如下

const getDefaultState = () => {

return {

…

roles: []

}

}

const mutations = {

…

SET_ROLES: (state, roles) => {

state.roles = roles

}

}

// get user info

getInfo({ commit, state }) {

return new Promise((resolve, reject) => {

getInfo(state.token).then(response => {

正式学习前端大概 3 年多了，很早就想整理这个书单了，因为常常会有朋友问，前端该如何学习，学习前端该看哪些书，我就讲讲我学习的道路中看的一些书，虽然整理的书不多，但是每一本都是那种看一本就秒不绝口的感觉。

以下大部分是我看过的，或者说身边的人推荐的书籍，每一本我都有些相关的推荐语，如果你有看到更好的书欢迎推荐呀。
