写这篇博客，刚好换了台电脑，那就借着这个demo复习下VUE环境的搭建。
一、前端项目搭建
1、安装node
官网下载安装即可。
2、安装脚手架
npm install -g vue-cli使用脚手架搭建一个demo前端项目
vue init webpack 项目名称3、安装依赖
这里安装了用到的element、jsonp等。
cnpm i element-ui -S
npm install vue-jsonp --save
npm install axios
npm install nprogress --save
npm install js-cookie
npm install --save vuex完整的package.json依赖文件： （

}二、项目代码
1、环境
主要配置后端接口地址、前端端口号
（1）config/dev.env.js
'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
BASE_API: '"http://localhost:2222/securityDemo/"',
})（2）test.env.js
'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
BASE_API: '"http://localhost:2222/securityDemo/"',
})（3）prod.env.js
'use strict'
module.exports = {
NODE_ENV: '"production"',
BASE_API: '"http://xxx.com/mydemo/"',
}（4）index
'use strict'
// Template version: 1.2.6
// see http://vuejs-templates.github.io/webpack for documentation.
const path = require('path')
module.exports = {

useEslint: true,
// If true, eslint errors and warnings will also be shown in the error overlay
// in the browser.
showEslintErrorsInOverlay: false,
/**

*/
// https://webpack.js.org/configuration/devtool/#development
devtool: 'cheap-source-map',
// If you have problems debugging vue-files in devtools,

},

assetsSubDirectory: 'static',

bundleAnalyzerReport: process.env.npm_config_report
}
}2、util
src下新建utils目录，封装工具类
（1）auth.js封装token操作方法
import Cookies from 'js-cookie'
const TokenKey = 'Admin-Token'
export function getToken() {
return Cookies.get(TokenKey)
}
export function setToken(token) {
return Cookies.set(TokenKey, token)
}
export function removeToken() {
return Cookies.remove(TokenKey)
}（2）request.js封装axois请求
import axios from 'axios'
// 配置前端跨域
axios.defaults.withCredentials = true
import { Message, MessageBox } from 'element-ui'
import store from '../store'
import { getToken } from '@/utils/auth'
// 创建axios实例
const service = axios.create({
baseURL: process.env.BASE_API, // api的base_url
timeout: 5000 // 请求超时时间
})
// request拦截器
service.interceptors.request.use(config => {
if (store.getters.token) {
config.headers['token'] = getToken() // 让每个请求携带自定义token 请根据实际情况自行修改
}
return config
}, error => {
// Do something with request error
console.log(error) // for debug
Promise.reject(error)
})
// respone拦截器
service.interceptors.response.use(
response => {
/**
* code为非20000是抛错 可结合自己业务进行修改
*/
const res = response.data
if (res.code !== 200 && res.code !=300) {
Message({
message: res.message,
type: 'error',
duration: 5 * 1000
})
// 401 token失效
if (res.code === 401) {
// MessageBox.confirm('你已被登出，可以取消继续留在该页面，或者重新登录', '确定登出', {
// confirmButtonText: '重新登录',
// cancelButtonText: '取消',
// type: 'warning'
// }).then(() => {
// store.dispatch('FedLogOut').then(() => {
// location.reload()// 为了重新实例化vue-router对象 避免bug
// })
// })
store.dispatch('FedLogOut').then(() => {
location.reload()// 为了重新实例化vue-router对象 避免bug
})
}
return Promise.reject('error')
} else {
return response.data
}
},
error => {
console.log('err' + error)// for debug
Message({
message: error.message,
type: 'error',
duration: 5 * 1000
})
return Promise.reject(error)
}
)
export default service3、api
src下新增api目录，封装后台接口调用
（1）login.js
import request from '@/utils/request'
//获取验证码
export function getCode(){
return request({
url: '/code/getCode',
method: 'get'
})
}
//登录
export function login(user) {
return request({
url: '/login',
method: 'post',
datatype:'application/json',
//data:user
params:{
"userName":user.userName,
"passWord": user.password
}
})
}
//获取我的权限列表
export function getMyAuthorities() {
return request({
url: '/user/getCurrentUser',
method: 'post'
})
}
//退出登录
export function logout() {
return request({
url: '/user/logout',
method: 'get'
})
}（2）user.js：
import request from '@/utils/request'
export function getAllUsers() {
return request({
url: '/user/getAllUsers',
method: 'get'
})
}4、store
src下新增store目录，store下按照以下示例新建文件
（1）index.js：
import Vue from 'vue'
import Vuex from 'vuex'
import app from './modules/app'
import permission from './modules/permission'
import user from './modules/user'
import getters from './getters'
Vue.use(Vuex)
const store = new Vuex.Store({
modules: {
app,
permission,
user
},
getters
})
export default store（2）getters.js：
const getters = {
sidebar: state => state.app.sidebar,
//token
token: state => state.user.token,
//用户名
name: state => state.user.name,
//角色
roles: state => state.user.roles,
//后台返回的权限code
authorities:state =>state.user.authorities,
//动态权限路由
permission_routers: state => state.permission.routers,
//固定权限路由
addRouters: state => state.permission.addRouters
}
export default getters（3）/mudules/app.js
import Cookies from 'js-cookie'
const app = {
state: {
sidebar: {
opened: !+Cookies.get('sidebarStatus'),
withoutAnimation: false
},
device: 'desktop'
},
mutations: {
TOGGLE_SIDEBAR: state => {
if (state.sidebar.opened) {
Cookies.set('sidebarStatus', 1)
} else {
Cookies.set('sidebarStatus', 0)
}
state.sidebar.opened = !state.sidebar.opened
state.sidebar.withoutAnimation = false
},
CLOSE_SIDEBAR: (state, withoutAnimation) => {
Cookies.set('sidebarStatus', 1)
state.sidebar.opened = false
state.sidebar.withoutAnimation = withoutAnimation
},
TOGGLE_DEVICE: (state, device) => {
state.device = device
}
},
actions: {
ToggleSideBar: ({ commit }) => {
commit('TOGGLE_SIDEBAR')
},
CloseSideBar({ commit }, { withoutAnimation }) {
commit('CLOSE_SIDEBAR', withoutAnimation)
},

}
}
}
export default app（4）/mudules/permission.js
import { asyncRouterMap, constantRouterMap } from '@/router/index'
/**

export default user5、router
asyncCodeMenu暂时没有用到，是准备存放各模块及其详情页路由的（避免index写的过长）。这里只贴index.js代码：import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
export const constantRouterMap = [
