后台管理不同的权限登录，后台的导航栏显示不同菜单

1.router.js  
路由页面的配置  
首先路由页面分两块，一块是默认的路由，无论用户的权限是什么，都会访问到的页面，也叫公共路由  
另一块是需要用户权限才能查看的某些特定的页面

import Vue from 'vue'
    import Router from 'vue-router'
    const login=()=>import('@/components/login.vue')
    const logon=()=>import('@/components/logon.vue')
    const menu=()=>import('@/components/menu/menu.vue')
    //...等等引入的页面路径
    
    Vue.use(Router)
    
    //默认的路由
    let defaultRouter=[
      { 
        path: '/',
        hidden: true,

（因公司使用项目，所以贴出了与权限相关项目，其他的没有贴出）

    </script>

3.store  
状态管理器存储token及权限  
![在这里插入图片描述][20200408180306375.png]  
index.js

import Vue from 'vue'
    import Vuex from 'vuex'
    import routeJump from './modules/RouteJump'
    import routerData from './modules/routerData'
    import role from './modules/role'
    Vue.use(Vuex)
    
    const store = new Vuex.Store({ 
      getters: { 
        addRouters: state => state.routerData.addRouters,
        info: state => state.role.info,
        routers: state => state.routerData.routers,
        token: state => state.routeJump.Authorization,
      },
      modules: { 
        routeJump,
        routerData,
        role
      },
    })
    export default store

routeJump.js  
（该页面是token的存储使用）

routerData.js  
（对不同的用户进行路由的筛选）

import { defaultRouter, addRouter} from '@/router/index'
    // console.log(addRouter)
    const routerData = { 
      state: { 
        routers: [],
        addRouters: []
      },
      mutations: { 
        setRouters: (state, routers) => { 
          state.addRouters = routers  // 保存动态路由用来addRouter
          state.routers = defaultRouter.concat(routers) // 所有有权限的路由表，用来生成菜单列表
        }
      },
      actions: { 
        newRoutes ({ commit}, role) { 
          // 通过递归路由表，删除掉没有权限的路由
          function eachSelect (routers, userRole) { 
            var data=[...routers];
            for (let j = 0; j < routers.length; j++) { 
              if (routers[j].meta && routers[j].meta.role.length>0 && routers[j].meta.role.indexOf(userRole) === -1) { 
                // console.log(routers[j])
                routers.splice(j, 1)
                j=j-1;
                continue;
              }
              if (routers[j].children && routers[j].children.length>0) { 
                eachSelect(routers[j].children, userRole)
              }
            }
            // console.log(routers)
          }
          eachSelect(addRouter, role)
          commit('setRouters', addRouter)
        }
      }
    }
    
    export default routerData

role .js

import store from '../index'
    import router from '../../router/index'
    export default { 
      state: { 
        info: ''  // 每次刷新都要通过token请求个人信息来筛选动态路由
      },
      mutations: { 
        getInfo (state, info) { 
          state.info = info
          sessionStorage.setItem('info', JSON.stringify(store.getters.info))
        },
      },
      actions: { 
        getInfo ({ commit}, token) { 
          commit('getInfo', token)
        },
      }
    }

4.main.js  
该页面需要引入路由，store

import router from './router'
    import store from './store/index'
    
      router.beforeEach((to, from, next) => { 
        // debugger
        if (sessionStorage.getItem('Authorization')) { //因为是后台管理，需要token验证
          if (to.path === '/login') { 
            next()
          } else { 
            if (!store.getters.info.role) { //在登录时把权限存在store里面
              !async function getAddRouters () { 
                if(sessionStorage.getItem('userType')!=1){ 
                    await store.dispatch('getInfo', { 
                      role: 'admin',
                      permissions: '超级管理员'
                    })
                }else{ 
                  await store.dispatch('getInfo', { 
                    role: 'user',
                    permissions: '用户'
                  })
                }
                
                await store.dispatch('newRoutes', store.getters.info.role)
    
                store.getters.addRouters.push({ //在动态路由最后追加*为404,若在router.js页面写的话当路由第一次跳转到需要权限的页面时会跳转到404页面
                  path: '*',

    new Vue({

      router,
      store,

以上是基本的配置，下面还剩menu的渲染了

以上就是全部了，本菜鸟也是第一次写权限方面的，网上百度了好久，参考了好多人的博客才写出来的，有大佬看见和你的有点类似也请见谅，（好不容易搞出来了，很多的博客是看完了就关上了，现在已经不知道参考的哪个了，你要是知道参考的网址，也可以告诉我哦，我再加上），代码上可能有很多不足的地方，欢迎提出，我会及时改正哒。。。大佬要是知道更简单易懂的也麻烦告诉我呀，好让身为菜鸟的我多学习学习，感谢感谢
