5 首页框架及路由配置

1 添加首页LayoutVue.vue组件，登录成功之后跳转到该组件

<script setup>
import {
    Management,
    Promotion,
    UserFilled,
    User,
    Crop,
    EditPen,
    SwitchButton,
    CaretBottom
} from '@element-plus/icons-vue'
import avatar from '@/assets/default.png'

// 导入ref
import { ref } from 'vue'

// 初始化isAdmin
const isAdmin = ref(false)

import { useTokenStore } from '@/stores/token.js'
const tokenStore = useTokenStore();



// 导入路由
import router from '@/router'
import { ElMessage, ElMessageBox } from 'element-plus'
//条目被点击后，调用的函数
const handleCommand = (command) => {
    if (command == 'logout') {
        //退出登录
        ElMessageBox.confirm(
            '你确认退出登录码？',
            '温馨提示',
            {
                confirmButtonText: '确认',
                cancelButtonText: '取消',
                type: 'warning',
            }
        )
            .then(async () => {
                //用户点击了确认
  
                tokenStore.token = ''
                //跳转到登录页
                router.push('/login')
            })
            .catch(() => {
                //用户点击了取消
                ElMessage({
                    type: 'info',
                    message: '取消退出',
                })
            })
    } else {
        router.push(`/user/${command}`);
    }
}


</script>

        <el-container>
            <!-- 头部区域 -->
            <el-header>
                <div>当前用户：<strong></strong></div>
                <el-dropdown placement="bottom-end" @command="handleCommand">

                            <el-dropdown-item command="logout" :icon="SwitchButton">退出登录</el-dropdown-item>
                        </el-dropdown-menu>
                    </template>
                </el-dropdown>
            </el-header>
            <!-- 中间区域 -->
            <el-main>
                <!-- <div style="width: 1290px; height: 570px;border: 1px solid red;">

                <router-view></router-view>
            </el-main>
            <!-- 底部区域 -->
            <el-footer>软件之声论坛 ©2024 Created by xumj</el-footer>
        </el-container>
    </el-container>
</template>

<style lang="scss" scoped>
.layout-container {
    height: 100vh;

    .el-aside {
        background-color: #232323;

        &__logo {
            height: 120px;
            background: url('@/assets/logo.png') no-repeat center / 120px auto;
        }

        .el-menu {
            border-right: none;
        }
    }

    .el-header {
        background-color: #fff;
        display: flex;
        align-items: center;
        justify-content: space-between;

        .el-dropdown__box {
            display: flex;
            align-items: center;

            .el-icon {
                color: #999;
                margin-left: 10px;
            }

            &:active,
            &:focus {
                outline: none;
            }
        }
    }

    .el-footer {
        display: flex;
        align-items: center;
        justify-content: center;
        font-size: 14px;
        color: #666;
    }
}
</style>

2 配置路由规则，并新建子组件（自行创建）

import { createRouter, createWebHistory } from 'vue-router'
import LayoutVue from '../views/LayoutVue.vue'
import Login from '../views/Login.vue'
import BookResourcesVue from '../views/books/BookResourcesVue.vue'
import BookRecordsVue from '../views/books/BookRecordsVue.vue'
import UserAvatarVUe from '../views/user/UserAvatarVUe.vue'
import UserResetPasswordVue from '../views/user/UserResetPasswordVue.vue'

import UserInfoVue from '../views/user/UserInfoVue.vue'
import UserManageVue from '../views/user/UserManageVue.vue'
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    { path: '/login', component: Login },
    {
      path: '/',
      component: LayoutVue,  //首页布局父组件
      redirect: '/book/resources',
      // 子路由
      children: [
        { path: '/book/resources', component: BookResourcesVue },
        { path: '/book/records', component: BookRecordsVue },
        { path: '/user/info', component: UserInfoVue },
        { path: '/user/avatar', component: UserAvatarVUe },
        { path: '/user/password', component: UserResetPasswordVue },
        { path: '/user/logout', component: Login },
        // 用户管理组件
        { path: '/user/manage', component: UserManageVue }
      ]
    }
  ]
})

export default router

3 修改首页布局中左侧导航代码，添加路由连接如下

    <!-- 左侧菜单 -->
        <el-aside width="200px">
            <div class="el-aside__logo"></div>
            <el-menu active-text-color="#ffd04b" background-color="#232323" text-color="#fff" router>
                <el-menu-item index="/book/resources">
                    <el-icon>
                        <Book />
                    </el-icon>
                    <span>图书资源</span>
                </el-menu-item>
                <!-- 如果是管理员就显示用户管理组件 否则就显示借阅记录组件 -->
                <el-menu-item v-if="!isAdmin" index="/book/records">
                    <el-icon>
                        <User />
                    </el-icon>
                    <span>借阅记录</span>
                </el-menu-item>
                <el-menu-item v-else index="/user/manage">
                    <el-icon>
                        <Document />
                    </el-icon>
                    <span>用户管理</span>
                </el-menu-item>
                <el-sub-menu>
                    <template #title>
                        <el-icon>
                            <UserFilled />
                        </el-icon>
                        <span>个人中心</span>
                    </template>
                    <el-menu-item index="/user/info">
                        <el-icon>
                            <User />
                        </el-icon>
                        <span>基本资料</span>
                    </el-menu-item>
                    <el-menu-item index="/user/avatar">
                        <el-icon>
                            <Crop />
                        </el-icon>
                        <span>更换头像</span>
                    </el-menu-item>
                    <el-menu-item index="/user/password">
                        <el-icon>
                            <EditPen />
                        </el-icon>
                        <span>重置密码</span>
                    </el-menu-item>
                </el-sub-menu>
            </el-menu>
        </el-aside>
