[JavaScript知识库]vueAdmin前端学习笔记

1.安装VUE项目

第一步：vue-ui

# 安装淘宝npm
npm install -g cnpm --registry=https://registry.npm.taobao.org
# vue-cli 安装依赖包
cnpm install --g vue-cli
# 打开vue的可视化管理工具界面
vue ui

第二步：创建

第三步：详情

第四步：选择手动

第五步：配置

第六步：点击创建项目

第七步：启动项目

第八步：vsCode启动项目

npm run serve

2.安装element-ui

npm install element-ui --save

然后我们打开项目src目录下的main.js，引入element-ui依赖。

import Element from 'element-ui'
import "element-ui/lib/theme-chalk/index.css"

Vue.use(Element)

这样我们就可以愉快得在官网上选择组件复制代码到我们项目中直接使用啦。

3.删除不必要的页面

3.1删除/viwes/Home.vue

3.2删除App.vue

4.安装axios、qs、mockjs

• axios：一个基于 promise 的 HTTP 库，类ajax

• qs：查询参数序列化和解析库

• mockjs：为我们生成随机数据的工具库

4.1安装axios

npm install axios --save

# 然后同样我们在main.js中全局引入axios
import axios from 'axios'
Vue.prototype.$axios = axios //全局使用

4.2安装qs

npm install qs --save

4.3安装mockjs

npm install mockjs --save-dev

5.页面路由

学习视频

5.1删除页面

5.2创建页面

1.创建Login.vue

<template>
    <div>登录页面</div>
</template>

<script>
export default {
    name: "Login"
}
</script>

<style scoped>

</style>

1.创建Home.vue

<template>
  <div>测试主页  </div>
</template>

<script> 

export default {
  name: 'Home',
 
}
</script>

<style>

</style>

5.3页面router/index.js

import Home from '../views/Home.vue'
import Login from '../views/Login.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'Home',
    component: Home
  },
  {
    path: '/login',
    name: 'Login',
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    // component: () => import(/* webpackChunkName: "about" */ '../views/Login.vue')  方式一
    component: Login  //方式二
  }
]

6.登录页面

6.1页面展示

6.2在src/App.vue调整全局样式

我们先调整一下全局的样式

将原页面的style便签删除，更换为一下的style便签内容，下面是调整后的整个页面

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<style>
html, body, #app {
  font-family: 'Helvetica Neue', 'Hiragino Sans GB', 'WenQuanYi Micro Hei', 'Microsoft Yahei', sans-serif;
  height: 100%;
  padding: 0;
  margin: 0;
  font-size: 15px;
}
</style>

6.3src/views/Login.vue

一下页面是写好后的页面，还未发请求前

<template>
  <el-row style="height: 100%">
    <el-col :xl="6" :lg="7">
      <!-- 标题 -->
      <h2>欢迎来到VueAdmin管理界面</h2>
      <!-- 使用 el-image引入图片 -->
      <el-image
          :src="require('@/assets/微信图片_20210919105336.jpg')"
          style="height: 180px; width: 180px"
      ></el-image>
      <p>公众号：MarkerHup</p>
      <p>扫描二维码，回复</p>
    </el-col>
    <el-col :span="1">
      <!-- 分割线 -->
      <el-divider direction="vertical"></el-divider>
    </el-col>
    <el-col :xl="6" :lg="7">
      <!--
      :model="loginForm" 绑定的表单
      :rules="rules"   校验规则
      ref="loginForm"  注册实例，可以通过  this.$refs[loginForm]获取
      -->
      <el-form
          :model="loginForm"
          :rules="rules"
          ref="loginForm"
          label-width="80px"
          class="demo-loginForm"
      >
        <el-form-item label="用户名" prop="userName" style="width: 380px">
          <el-input v-model="loginForm.userName"></el-input>
        </el-form-item>

        <el-form-item label="密码" prop="passWord" style="width: 380px">
          <el-input v-model="loginForm.passWord"></el-input>
        </el-form-item>

        <el-form-item label="验证码" prop="code" style="width: 380px">
          <el-input
              v-model="loginForm.code"
              style="width: 170px; float: left"
          ></el-input>
          <el-image src="" class="captchaImg"></el-image>
        </el-form-item>

        <el-form-item>
          <el-button type="primary" @click="submitForm('loginForm')"
          >登录
          </el-button>
          <el-button @click="resetForm('loginForm')">重置</el-button>
        </el-form-item>
      </el-form>
    </el-col>
  </el-row>
</template>

<script>
export default {
  name: "Login",

  data() {
    return {
      // 表单
      loginForm: {
        userName: "",
        passWord: "",
        code: "",
      },
      //   校验
      rules: {
        userName: [
          {required: true, message: "请输入用户名", trigger: "blur"},
          {
            min: 3,
            max: 50,
            message: "长度在 3 到 50 个字符",
            trigger: "blur",
          },
        ],
        passWord: [
          {required: true, message: "请输入密码", trigger: "change"},
        ],

        code: [{required: true, message: "请输入验证码", trigger: "change"}],
      },
    };
  },
  methods: {
    submitForm(formName) {
      this.$refs[formName].validate((valid) => {
        if (valid) {
          alert("submit!");
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    },
    resetForm(formName) {
      this.$refs[formName].resetFields();
    },
  },
};
</script>

<style scoped>
/**
* el-row 的设置
*    background-color: #fafafa;   设置背景颜色
*    height: 100%;  设置高度，覆盖所有的高度
*    display: flex;    横向居中
*    align-items: center; 上下居中

*/

.el-row {
  background-color: #fafafa;
  height: 100%;
  display: flex;
  align-items: center;
  text-align: center;
  justify-content: center;
}

/*.el-row {*/
/*  height: 100%;*/
/*  background-color: #fafafa;   !*设置背景颜色*!*/
/*  display: flex;*/
/*  justify-content: center;*/
/*  align-items: center;*/
/*  text-align: center;*/
/*}*/

/* 分割线的高度 */
.el-divider {
  height: 200px;
}

.captchaImg {
  /*靠左边*/
  float: left;
  /*验证码偏移8px*/
  margin-left: 8px;
  /*圆角*/
  border-radius: 4px;
}
</style>

6.4获取验证码

现在没有后端，用mockjs模拟生成验证码

6.4.1安装mockjs

npm install mockjs --save-dev

6.4.2创建mock.js

// 引入mockjsconst
const  Mock  = require('mockjs')
// 获取 mock.Random 对象
// 参考：https://github.com/nuysoft/Mock/wiki/Mock.Random
const Random = Mock.Random

let  Result = {
    code: 200,
    msg: '操作成功',
    data: null
}
Mock.mock('/captcha','get',()=>{
    Result.data = {
        UUID: Random.string(32),  // 获取一个32位的随机字符串,
        captchaImg: Random.dataImage('120x40','p7n5w')  //生成验证码为11111的base64图片编码
    }
    return Result
})

6.4.3注册

// 在src/main,js
require("./mock.js")

6.4.4login页面(重要)

• 在methods添加请求验证码的方法

    // 获取验证码
    getCaptCha() {
      this.$axios.get('/captcha').then(res => {
        debugger;
        this.loginForm.UUID = res.data.data.token;
        this.captchaImg = res.data.data.captchaImg;
      })
    }

• 新增created在进入页面时加载

  created() {
    this.getCaptCha();
  },

• 新增参数

1.在loginForm里添加UUID，

2.在data里面添加captchaImg，

3.验证码展示

<el-image :src="captchaImg" class="captchaImg"></el-image>

6.4.5页面展示

6.5登录

6.5.1使用mockjs模拟登录

在mock.js添加

Mock.mock('/login','post',()=>{    return Result})

6.5.2将token存到localStorage

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default new Vuex.Store({
    state: {
        token: ''
    },
    mutations: {
        SET_TOKEN: (state, token) => {
            state.token = token;
            localStorage.setItem("token", token)
        }
    },
    actions: {},
    modules: {}
})

6.5.3发送login请求

this.$axios.post('/login', this.loginForm).then(res => {
  const jwt = res.headers['authorization'];
  this.$store.commit("SET_TOKEN", jwt);
  this.$router.push("/index");
})

6.5.4测试

7.定义全局axios拦截器

7.1在src/axios.js

import axios from "axios";import router from "@/router";import Element from "element-ui"axios.defaults.daseURL = "http://localhost:8081"const request = axios.create({    timeout: 5000,  //超时时间    headers: {        'Content-Type': 'application/json; charset=utf-8' //  返回的JSON类型数据    }})// 请求的拦截，查看是否有tokenrequest.interceptors.request.use(config => {    config.headers['Authorization'] = localStorage.getItem("token") // 请求头带上token    return config})// 返回的结果request.interceptors.response.use(response => {    let res = response.data;    console.log("response")    console.log(res)    if (res.code === 200) {        return response    } else {        Element.Message.error(res.msg ? res.msg : '系统异常！', {duration: 3 * 1000})        return Promise.reject(response.data.msg)    }}, error => {   // 异常的情况    console.log(error)    if (error.response.data) {        error.message = error.response.data.msg    }    // 401没有权限    if (error.response.status === 401) {        router.push("/login")    }    Element.Message.error(error.message, {duration: 3 * 1000})    return Promise.reject(error)})export default request

7.2在main.js全局引入

7.3测试

1.在mock.js中的login方法添加错误信息

2.页面测试

8.index页面编写

8.1页面

在src/views/创建index.vue

<template>
  <el-container>
    <!--  侧边栏-->
    <el-aside width="200px">


      <el-menu

<template>
  <div>角色测试</div>
</template>

<script>

export default {
  name: 'Role',

}
</script>

<style>

</style>

10.3在views新建system/Menuvue

<template>
  <div>菜单测试</div>
</template>

<script>

export default {
  name: 'Menu',
}
</script>

<style>

</style>

10.4在router.js添加

以下是代码router.js代码

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
import Login from '../views/Login.vue'
import Index from '@/views/index'
import User from "@/views/system/User";
import Role from "@/views/system/Role";
import Menu from "@/views/system/Menu";

Vue.use(VueRouter)

const routes = [
    {
        path: '/',
        name: 'Home',
        component: Home,
        children: [
            {
                path: '/index',
                name: 'Index',
                component: Index
            },
            {
                path: '/users',
                name: 'SysUser',
                component: User
            },
            {
                path: '/roles',
                name: 'SysRole',
                component: Role
            },
            {
                path: '/menus',
                name: 'SysMenu',
                component: Menu
            },
        ]
    },
    {
        path: '/login',
        name: 'Login',
        // route level code-splitting
        // this generates a separate chunk (about.[hash].js) for this route
        // which is lazy-loaded when the route is visited.
        // component: () => import(/* webpackChunkName: "about" */ '../views/Login.vue')  方式一
        component: Login  //方式二
    },

]

const router = new VueRouter({
    mode: 'history',
    base: process.env.BASE_URL,
    routes
})

export default router

10.4测试

分别访问：看页面的变化

http://localhost:8080/menus

http://localhost:8080/roles

http://localhost:8080/users

11.导航栏绑定页面

完成后点击页面测试看是否发生变化

<router-link to="/users">

</router-link>

12修改头像和用户名

在inc/SideHeader中修改头像和用户名从后端获取

13.个人中心

13.1在views/system/新建UserCenter.vue

<template>
  <div style="text-align: center;"><h2>你好！{{ userInfo.username }} 同学</h2>
    <el-form :model="passForm" status-icon :rules="rules" ref="passForm" label-width="100px">
      <el-form-item label="旧密码" prop="currentPass">
        <el-input type="password" v-model="passForm.currentPass" autocomplete="off"></el-input>
      </el-form-item>
      <el-form-item label="新密码" prop="password">
        <el-input type="password" v-model="passForm.password" autocomplete="off"></el-input>
      </el-form-item>
      <el-form-item label="确认密码" prop="checkPass">
        <el-input type="password" v-model="passForm.checkPass" autocomplete="off"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="submitForm('passForm')">提交</el-button>
        <el-button @click="resetForm('passForm')">重置</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>
<script>
export default {
  name: "Login", data() {
    var validatePass = (rule, value, callback) => {
      if (value === '') {
        callback(new Error('请再次输入密码'));
      } else if (value !== this.passForm.password) {
        callback(new Error('两次输入密码不一致!'));
      } else {
        callback();
      }
    };
    return {
      userInfo: {},
      passForm: {password: '111111', checkPass: '111111', currentPass: '111111'},
      rules: {
        password: [{required: true, message: '请输入新密码', trigger: 'blur'}, {
          min: 6,
          max: 12,
          message: '长度在 6 到 12 个字符',
          trigger: 'blur'
        }],
        checkPass: [{required: true, validator: validatePass, trigger: 'blur'}],
        currentPass: [{required: true, message: '请输入当前密码', trigger: 'blur'},]
      }
    }
  }, created() {
    this.getUserInfo()
  }, methods: {
    getUserInfo() {
      this.$axios.get("/sys/userInfo").then(res => {
        this.userInfo = res.data.data;
      })
    }, submitForm(formName) {
      this.$refs[formName].validate((valid) => {
        if (valid) {
          const _this = this
          this.$axios.post('/sys/user/updataPass', this.passForm).then(res => {
            _this.$alert(res.data.msg, '提示', {
              confirmButtonText: '确定', callback: action => {
                this.$refs[formName].resetFields();
              }
            });
          })
        } else {
          console.log('error submit!!');
          return false;
        }
      });
    }, resetForm(formName) {
      this.$refs[formName].resetFields();
    }
  }
}
</script>
<style scoped>
.el-form {
  width: 420px;
  margin: 50px auto;
}
</style>

13.2在router.js添加

{
    path: '/userCenter',
    name: 'UserCenter',
    component: ()=>import("@/views/system/UserCenter")
},

13.3修改SideHeader.vue

删除所有页面的 line-height: 160px;

13.4测试页面

14退出

• 在SideHeader.vue给退出添加点击按钮

<!-- 在el-dropdown-item标签里， @click不可以用，要使用@click.native-->
<el-dropdown-item @click.native="logout">退出</el-dropdown-item>

• 在SideHeader.vue的methods编写点击退出方法

logout(){
  this.$axios.post("/logout").then(res => {
    localStorage.clear();
    sessionStorage.clear();
    this.$store.commit("resetState");
    this.$router.push("/login")
  })
},

• 在store/index.js添加删除的方法

• 在mock.js模拟退出请求

Mock.mock('/logout','post',()=>{    return Result})

• 测试

点击页面退出看效果

15将导航改为动态获取(可忽略)

可以忽略，直接过16

先用mock.js模拟从服务器返回数据

15.1主要修改

15.2修改后SideMenu.vue的页面

<template>
  <el-menu
      default-active="2"
      class="el-menu-vertical-demo"
      @open="handleOpen"
      @close="handleClose"
      background-color="#545c64"
      text-color="#fff"
      active-text-color="#ffd04b">
    <router-link to="/index">
      <el-menu-item index="Index">
        <template slot="title"><i :class="el-icon-s-home"></i> <span slot="title">首页</span></template>
      </el-menu-item>
    </router-link>

    <el-submenu :index=menu.name
                v-for="menu in menuList">
      <template slot="title">
        <i :class="menu.icon"></i>
        <span>{{ menu.title }}</span>
      </template>
      <router-link :to="item.path" v-for="item in menu.children">
        <el-menu-item :index="item.name">
          <template slot="title">
            <i :class="item.icon"></i> 
            <span slot="title">{{ item.title }}</span>
          </template>
        </el-menu-item>
      </router-link>
    </el-submenu>
  </el-menu>
</template>

<script>

export default {
  name: 'SideMenu',
  data() {
    return {
      menuList: [],
    }

  },
  created() {
    this.getMenuList();
  },
  methods: {
    getMenuList() {
      this.$axios.get("/sys/menuList").then(res => {
        this.menuList = res.data.data;
      })
    }
  }


}
</script>

<style>
.el-menu-vertical-demo {
  height: 100%;
}

.a {
  text-decoration: none;
}
</style>

15.3mock.js

Mock.mock('/sys/menuList', 'get', () => {
    Result.data = [
        {
            name: 'SysManga',
            title: '系统管理',
            icon: 'el-icon-s-operation',
            path: '',
            component: '',
            children: [
                {
                    name: 'SysUser',
                    title: '用户管理',
                    icon: 'el-icon-s-custom',
                    path: '/users',
                    children: []
                }]
        }, {
            name: 'SysTools',
            title: '系统工具',
            icon: 'el-icon-s-tools',
            path: '',
            children: [
                {
                    name: 'SysDict',
                    title: '数字字典',
                    icon: 'el-icon-s-order',
                    path: '/dicts',
                    children: []
                },]
        }
    ]
    return Result
})

15.4修改后的导航栏

16.将导航栏改为动态获取

16.1mock.js模拟后端返回的数据

修改15的mock.js后的方法

Mock.mock('/sys/menuList', 'get', () => {

    // 导航菜单
    let nav = [
        {
            name: 'SysManga',
            title: '系统管理',
            component:'',
            icon: 'el-icon-s-operation',
            path: '',
            component: '',
            children: [
                {
                    name: 'SysUser',
                    title: '用户管理',
                    component:'system/User',
                    icon: 'el-icon-s-custom',
                    path: '/users',
                    children: []
                }]
        }, {
            name: 'SysTools',
            title: '系统工具',
            component:'',
            icon: 'el-icon-s-tools',
            path: '',
            children: [
                {
                    name: 'SysDict',
                    title: '数字字典',
                    component:'',
                    icon: 'el-icon-s-order',
                    path: '/dicts',
                    children: []
                },]
        }
    ]
    // 权限
    let authoritys = []
    Result.data = {
        nav: nav,
        authoritys: authoritys
    }
    return Result
})

16.2将菜单/权限存放到全局

在/store/创建modules/menus.js

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default {
    state: {
        // 导航栏菜单
        menuList: [],
        // 权限
        permList: [],
        // 每次刷新都获取菜单，消耗服务器，可以将他存到sessionStorage中
        hasRoute: false
    },
    mutations: {
        setMenuList(state, menuList) {
            state.menuList = menuList
        },
        setPermList(state, permList) {
            state.setPermList = permList;
        },
        changeRouteStatus(state, hasRoute) {
            state.hasRoute = hasRoute;
            sessionStorage.setItem("hasRoute", hasRoute)
        },
    },
    actions: {},
    modules: {}
}

16.3将menus.js注册到src/store/index.js

16.4修改route/index.js方法

添加这个方法，注释掉写死的children的菜单，动态获取，下面有修改后的整个页面

router.beforeEach(((to, from, next) => {

    let hasRoute = store.state.menus.hasRoute
    console.log("hasRoute", hasRoute)
    // 当它没有的时候获取菜单
    if (!hasRoute) {
        // 获取菜单的方法，并校验token(token是之前存到localStorage中的)
        axios.get("/sys/menuList", {
            headers: {
                Authorization: localStorage.getItem("token")
            }
        }).then(res => {
            // 拿到menuList
            store.commit("setMenuList", res.data.data.nav)
            // 拿到用户权限
            store.commit("setPermList", res.data.data.authoritys)
            // 动态绑定路由(把拿到的menuList循环)
            let newRoutes = router.options.routes
            res.data.data.nav.forEach(menu => {
                if (menu.children) {
                    menu.children.forEach(e => {
                        // 转换成路由
                        if (e.component) {
                            console.log("e.component", e.component)
                            let route = {
                                name: e.name,
                                path: e.path,
                                mate: {
                                    icon: e.icon,
                                    title: e.title
                                },
                                component: () => import("@/views/" + e.component + '.vue')
                            }
                            // 把转换后的路由添加到路由管理器
                            if (route) {
                                newRoutes[0].children.push(route)
                            }
                        }

                    })
                }
            })
            console.log("newRoutes", newRoutes)
            router.addRoutes(newRoutes)
            // 获取到菜单，将他改为true
            hasRoute = true
            store.commit("changeRouteStatus", hasRoute)

        })
    }

    next()
}))

                            }
                            // 把转换后的路由添加到路由管理器
                            if (route) {
                                newRoutes[0].children.push(route)
                            }
                        }

                    })
                }
            })
            console.log("newRoutes", newRoutes)
            router.addRoutes(newRoutes)
            hasRoute = true
            console.log("hasRoute2", hasRoute)
            store.commit("changeRouteStatus", hasRoute)

        })
    }

    next()
}))

export default router

16.5修改/inc/SideMenu.vue

修改后的整个页面

<template>
  <el-menu
      default-active="2"
      class="el-menu-vertical-demo"
      @open="handleOpen"

  }


}
</script>

<style>
.el-menu-vertical-demo {
  height: 100%;
}

.a {
  text-decoration: none;
}
</style>

17动态标签页

17.1在/store/modules/menus.js添加

17.2在inc/新建Tabs.vue

<template>
  <el-tabs v-model="editableTabsValue" type="card" closable @tab-remove="removeTab" @tab-click="clickTab">
    <el-tab-pane
        v-for="(item, index) in editableTabs"
        :key="item.name"
        :label="item.title"
        :name="item.name"
    >
    </el-tab-pane>
  </el-tabs>
</template>

<script>

export default {
  name: 'Tabs',
  data() {
    return {
      // editableTabsValue: this.$store.state.menus.editableTabsValue,
      // editableTabs: this.$store.state.menus.editableTabs,
    }
  },

  // tab标签放到computed里面监听
  computed: {
    editableTabsValue: {
      // getter方法
      get() {
        return this.$store.state.menus.editableTabsValue
      },
      // setter方法
      set(val) {
        this.$store.state.menus.editableTabsValue = val
      }
    },
    editableTabs: {
      // getter方法
      get() {
        return this.$store.state.menus.editableTabs
      },
      // setter方法
      set(val) {
        this.$store.state.menus.editableTabs = val
      }
    }
  },
  methods: {
    // 点击tab标签切换页面数据
    clickTab(target) {
      this.$router.push({name: target.name})
    },

    removeTab(targetName) {
      let tabs = this.editableTabs;
      let activeName = this.editableTabsValue;

      // 首页不能删除
      if (activeName==='Index'){
        return
      }

      if (activeName === targetName) {
        tabs.forEach((tab, index) => {
          if (tab.name === targetName) {
            let nextTab = tabs[index + 1] || tabs[index - 1];
            if (nextTab) {
              activeName = nextTab.name;
            }
          }
        });
      }

      this.editableTabsValue = activeName;
      this.editableTabs = tabs.filter(tab => tab.name !== targetName);
      // 删除标签，就切换标签
      this.$router.push({name: activeName})
    }
  }

}
</script>

<style>

</style>

17.3页面使用

在视图上面添加Tabs组件

17.4修改inc/SideMenu.vue

添加selectMenu点击事件添加tab标签

:default-active是标签点击是相应的菜单高亮

<template>

<!--点击tab时菜单高亮 :default-active=this.$store.state.menus.editableTabsValue-->
  <el-menu
      :default-active=this.$store.state.menus.editableTabsValue
      class="el-menu-vertical-demo"
      background-color="#545c64"
      text-color="#fff"
      active-text-color="#ffd04b">
    <router-link to="/index">
      <el-menu-item index="Index">
        <template slot="title">
          <i class="el-icon-s-home"></i>
          <span slot="title">首页</span></template>
      </el-menu-item>
    </router-link>

    <el-submenu :index=menu.name
                v-for="menu in menuList">
      <template slot="title">
        <i :class="menu.icon"></i>
        <span>{{ menu.title }}</span>
      </template>
      <router-link :to="item.path" v-for="item in menu.children">
        <el-menu-item :index="item.name" @click="selectMenu(item)">
          <template slot="title">
            <i :class="item.icon"></i>
            <span slot="title">{{ item.title }}</span>
          </template>
        </el-menu-item>
      </router-link>
    </el-submenu>
  </el-menu>
</template>

<script>

export default {
  name: 'SideMenu',
  data() {
    return {
      // menuList: [],
    }

  },
  computed: {
    // this.getMenuList();
    menuList: {
      get() {
        //return this.$store.state+ menus.js的模块名+menuList
        return this.$store.state.menus.menuList
      }
    }
  },
  methods: {
    // getMenuList() {
    //   this.$axios.get("/sys/menuList").then(res => {
    //     this.menuList = res.data.data.nav;
    //   })
    // }
    selectMenu(item){
      this.$store.commit("addTab",item)
    }
  },
}
</script>

<style>
.el-menu-vertical-demo {
  height: 100%;
}

.a {
  text-decoration: none;
}
</style>

18通过url地址跳转

在src/App.vue添加方法

http://localhost:8080/users跳转不过去，添加以下代码

<script>
export default {
  name: "App",
  watch: {
    $route(to, from) {
      debugger;
      console.log("to",to)
      if (to.path != "/login") {
        let obj = {
          name: to.name,
          title: to.name
        }
        this.$store.commit("addTab", obj)
      }
    }
  }
}
</script>

19退出清空信息

在src/store/modules/menus.js的mutations方法里添加，因为退出已经调用过resetState这个，直接添加即可

resetState: (state) => {
    // 导航栏菜单
    state.menuList = [],
        // 权限
        state.permList = [],
        // 每次刷新都获取菜单，消耗服务器，可以将他存到sessionStorage中
        state.hasRoute = false,
        // tab标签默认为首页
        state.editableTabsValue = 'Index',
        state.editableTabs = [{
            title: '首页',
            name: 'Index',
        }]
},

20.菜單頁面

20.1是文字不居中

將.el-main的text-align: center;刪除

.el-main {
  color: #333;
  /*text-align: center;*/
  /*line-height: 160px;*/
  padding: 0;
}

20.2mock.js模拟后端

 菜单管理 
// 获取菜单管理列表
Mock.mock('/sys/menu/list', 'get', () => {
    let menus = [
        {
            "id": 1,
            "created": "2021-01-15T18:58:18",

23前端权限控制

23.1在src/main.js添加

Vue.mixin({
    methods: {
        hasAuth(perm) {
            var authority = this.$store.state.menus.permList
            console.log(authority)
            return authority.indexOf(perm) > -1
        }
    }
})

23.2使用权限

:v-if="hasAuth('sys:user:save')"

23.2mock.js模拟返回权限

// 权限
let authoritys = ['sys:user:save']

23.3其他

之前写的

1.在src/store/modules/menus.js设置权限的方法

2.在src/router/index.js拿到权限并设置到localStorage中

// 拿到用户权限
store.commit("setPermList", res.data.data.authoritys)
