群控系统服务端开发模式-应用开发-前端个人资料开发
一、总结
其实程序开发到现在，简单的后端框架就只剩下获取登录账号信息及获取登录账号菜单这两个功能咯。详细见下图：
1、未登录时总业务流程图
2、登录后总业务流程图
二、获取登录账号信息对接
在根目录下src文件夹下store文件夹下modules文件夹下的user.js文件中，修改代码如下：
const state = {
token: getToken(),
username: '',
avatar: '',
email: '',
realname: '',
department_title: '',
grade_title: '',
rolename: '',
roles: [],
butts: []
}
const mutations = {
SET_TOKEN: (state, token) => {
state.token = token
},
SET_EMAIL: (state, email) => {
state.email = email
},
SET_USERNAME: (state, username) => {
state.username = username
},
SET_AVATAR: (state, avatar) => {
state.avatar = avatar
},
SET_REALNAME: (state, realname) => {
state.realname = realname
},
SET_DEPARTMENT_TITLE: (state, department_title) => {
state.department_title = department_title
},
SET_GRADE_TITLE: (state, grade_title) => {
state.grade_title = grade_title
},
SET_ROLENAME: (state, rolename) => {
state.rolename = rolename
},
SET_BUTTS: (state, butts) => {
state.butts = butts
},
SET_ROLES: (state, roles) => {
state.roles = roles
}
}
// get user info
getInfo({commit, state}) {
return new Promise((resolve, reject) => {
getInfo().then(response => {
const {data} = response
if (!data) {
reject('验证失败，请重新登录。')
}
const { butt, key, username, avatar, email, realname, department_title, grade_title, rolename } = data
if (!butt || butt.length <= 0) {
reject('您权限不足,请联系系统管理员')
}
commit('SET_BUTTS', butt)
commit('SET_ROLES', key)
commit('SET_USERNAME', username)
commit('SET_AVATAR', avatar)
commit('SET_EMAIL', email)
commit('SET_REALNAME', realname)
commit('SET_DEPARTMENT_TITLE', department_title)
commit('SET_GRADE_TITLE', grade_title)
commit('SET_ROLENAME', rolename)
resolve(key)
}).catch(error => {
reject(error)
})
})
},三、获取登录账号菜单信息对接
获取菜单这块，需要更改两部分，第一部分就是路由修改，第二部分才是菜单转换成路由
1、路由修改
在根目录下src文件夹下route文件夹下，修改index.js文件，代码如下
import Vue from 'vue'
import Router from 'vue-router'
/* Layout */
import Layout from '@/layout'
Vue.use(Router)
/**
* Note: sub-menu only appear when route children.length >= 1
* Detail see: https://panjiachen.github.io/vue-element-admin-site/guide/essentials/router-and-nav.html
*
* hidden: true if set true, item will not show in the sidebar(default is false)
* alwaysShow: true if set true, will always show the root menu
* if not set alwaysShow, when item has more than one children route,
* it will becomes nested mode, otherwise not show the root menu
* redirect: noRedirect if set noRedirect will no redirect in the breadcrumb
* name:'router-name' the name is used by <keep-alive> (must set!!!)
* meta : {
roles: ['admin','editor'] control the page roles (you can set multiple roles)
title: 'title' the name show in sidebar and breadcrumb (recommend set)
icon: 'svg-name'/'el-icon-x' the icon show in the sidebar
noCache: true if set true, the page will no be cached(default is false)
affix: true if set true, the tag will affix in the tags-view
breadcrumb: false if set false, the item will hidden in breadcrumb(default is true)
activeMenu: '/example/list' if set path, the sidebar will highlight the path you set
}
*/
/**
* constantRoutes
* a base page that does not have permission requirements
* all roles can be accessed
*/
export const constantRoutes = [
{
path: '/redirect',
component: Layout,
hidden: true,
children: [
{
path: '/redirect/:path(.*)',
component: () => import('@/views/redirect/index')
}
]
},
{
path: '/login',
component: () => import('@/views/login/index'),
hidden: true
},
{
path: '/404',
component: () => import('@/views/error-page/404'),
hidden: true
},
{
path: '/401',
component: () => import('@/views/error-page/401'),
hidden: true
},
{
path: '/',
component: Layout,
redirect: '/dashboard',
children: [
{
path: 'dashboard',
component: () => import('@/views/dashboard/index'),
name: '首页',
meta: { title: '首页', icon: 'dashboard', affix: true }
}
]
},
{
path: '/profile',
component: Layout,
redirect: '/profile/index',
hidden: true,
children: [
{
path: 'index',
component: () => import('@/views/profile/index'),
name: 'Profile',
meta: { title: 'Profile', icon: 'user', noCache: true }
}
]
}
]
/**
* asyncRoutes
* the routes that need to be dynamically loaded based on user roles
*/
export const asyncRoutes = [
// 404 page must be placed at the end !!!
{ path: '*', redirect: '/404', hidden: true }
]
const createRouter = () => new Router({
// mode: 'history', // require service support
scrollBehavior: () => ({ y: 0 }),
routes: constantRoutes
})
const router = createRouter()
// Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465
export function resetRouter() {
const newRouter = createRouter()
router.matcher = newRouter.matcher // reset router
}
export default router
2、登录者菜单转换成路由
在根目录下src文件夹下store文件夹下modules文件夹下，修改permission.js文件，代码如下
import {asyncRoutes, constantRoutes} from '@/router'
import {getPersonalMenu} from '@/api/common'
import {warn} from '@/utils/message'
import Layout from '@/layout'
/**
* 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)
}
}
/**
* 后台查询的菜单数据拼装成路由格式的数据
* @param routes
*/
export function generaMenu(routes, data) {
data.forEach(item => {
const menu = {
path: item.path === '#' ? item.id + '_key' : item.path,
component: item.component === '#' ? Layout : resolve => require([`@/views/${item.component}`], resolve),
hidden: item.is_hidden,
redirect: item.redirect,
children: [],
name: 'menu_' + item.menuname,
alwaysShow: item.always_show,
meta: {
title: item.title,
id: item.id,
icon: item.is_icon === 1 ? item.icon : '',
/* affix: item.affix,*/
noCache: item.is_cache
}
}
// 一级路由
if (!item.children && item.pid === 0) {
menu.name = undefined
menu.children = [
{
path: item.path,
component: resolve => require([`@/views/${item.path}`], resolve),
name: 'menu_' + item.menuname,
meta: {
title: item.title,
icon: item.is_icon === 1 ? item.icon : '',
noCache: item.is_cache,
//affix: item.affix
}
}
]
}
// 二级路由
if (item.children) {
generaMenu(menu.children, item.children)
}
routes.push(menu)
})
}
function filterMenus(localMenus, remoteMenus) {
const res = []
localMenus.forEach(local => {
remoteMenus.forEach(remote => {
if (remote.path === local.path) {
local.meta.roles = remote.roleSlugs
if (local.children && remote.children) {
local.children = filterMenus(local.children, remote.children)
}
res.push(local)
}
})
})
return res
}
const actions = {
generateRoutes({commit, state}, key) {
return new Promise(resolve => {
const loadMenuData = []
getPersonalMenu().then(res => {
if (res.code === 50034) {
reject(res.message)
} else if (res.code === 50000) {
warn(res.message)
} else {
const remoteRoutes = res.data.menu
Object.assign(loadMenuData, remoteRoutes)
const tempAsyncRoutes = Object.assign([], asyncRoutes)
generaMenu(tempAsyncRoutes, loadMenuData)
let accessedRoutes
/*if (key == 'admin') {
accessedRoutes = tempAsyncRoutes || []
} else {
accessedRoutes = filterAsyncRoutes(tempAsyncRoutes, key)
}*/
accessedRoutes = filterAsyncRoutes(tempAsyncRoutes, key)
commit('SET_ROUTES', accessedRoutes)
resolve(accessedRoutes)
}
}).catch(error => {
reject(error)
})
})
}
}
export default {
namespaced: true,
state,
mutations,
actions
}
四、提前说明
此时就已经可以登录到系统里面去了，结果如下图。明天将完成个人资料页面、退出及后端过期退出自动更新数据库的退出数据。
