项目是github下载的  地址 https://gitee.com/panjiachen/vue-element-admin

由于分支较多,最初我下载的master版本的 但是由于不知道在那块处理国际化 系统默认是英文 所以我下载的 i18n版本

特此说明防止大家版本不一样导致文件目录有差异.

修改最大的地方就是 src/store/modules/permission.js

标红部分是我自己新加的或者修改过的参加参考就可以了,代码如下:

import { asyncRoutes, constantRoutes } from '@/router'
import { getAuthMenu } from '@/api/user'
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
  }
}

/**
 * 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 => {
    // alert(JSON.stringify(item))
    const menu = {
      path: item.url === '#' ? item.menu_id + '_key' : item.url,
      component: item.url === '#' ? Layout : () => import(`@/views${item.url}/index`),
      // hidden: true,
      children: [],
      name: 'menu_' + item.menu_id,
      meta: { title: item.menu_name, id: item.menu_id, roles: ['admin'] }
    }
    if (item.children) {
      generaMenu(menu.children, item.children)
    }
    routes.push(menu)
  })
}

/**
 * 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 loadMenuData = []
      // 先查询后台并返回左侧菜单数据并把数据添加到路由
      getAuthMenu(state.token).then(response => {
        let data = response
        if (response.code !== 0) {
          this.$message({
            message: '菜单数据加载异常',
            type: 0
          })
        } else {
          data = response.data.menuList
          Object.assign(loadMenuData, data)
          generaMenu(asyncRoutes, loadMenuData)
          let accessedRoutes
          if (roles.includes('admin')) {
            // alert(JSON.stringify(asyncRoutes))
            accessedRoutes = asyncRoutes || []
          } else {
            accessedRoutes = filterAsyncRoutes(asyncRoutes, roles)
          }
          commit('SET_ROUTES', accessedRoutes)
          resolve(accessedRoutes)
        }
        // generaMenu(asyncRoutes, data)
      }).catch(error => {
        console.log(error)
      })
    })
  }
}

export default {
  namespaced: true,
  state,
  mutations,
  actions
}

基本就这么多,是不是很easy 为了方便我把我后台调用的地方代码也贴出来

src/api/user.js

import request from '@/utils/request'

export function login(data) {
  return request({
    url: '/user/userLogin', // http://192.168.200.185:8090/user/login
    method: 'post',
    data
  })
}

export function getInfo(token) {
  return request({
    url: '/user/info',
    method: 'get',
    params: { token }
  })
}

export function logout() {
  return request({
    url: '/user/logout',
    method: 'post'
  })
}

export function getAuthMenu(token) {
  return request({
    url: '/dashboard',
    method: 'get',
    params: { token }
  })
}

到此结束.有的小伙伴不知道后台返回数据森马格式 这里我也贴出来供大家参考,为了说明问题 我只提取了部分数据
