登录访问拦截

需求：只有登录页，可以未授权的时候访问，其他所有页面，都需要先登录再访问

// 登录访问拦截
router.beforeEach((to) => {const userStore = useUserStore()if (!userStore.token && to.path !== '/login') return '/login'
})

用户基本信息获取&渲染

1. api/user.js封装接口

export const userGetInfoService = () => request.get('/my/userinfo')

2. stores/modules/user.js 定义数据

const user = ref({})
const getUser = async () => {const res = await userGetInfoService() // 请求获取数据user.value = res.data.data
}

3. layout/LayoutContainer页面中调用

import { useUserStore } from '@/stores'
const userStore = useUserStore()
onMounted(() => {userStore.getUser()
})

4. 动态渲染

<div>黑马程序员：<strong>{{ userStore.user.nickname || userStore.user.username }}</strong>
</div><el-avatar :src="userStore.user.user_pic || avatar" />

退出功能 [element-plus 确认框]

1. 注册点击事件

<el-dropdown placement="bottom-end" @command="onCommand"><el-dropdown-menu><el-dropdown-item command="profile" :icon="User">基本资料</el-dropdown-item><el-dropdown-item command="avatar" :icon="Crop">更换头像</el-dropdown-item><el-dropdown-item command="password" :icon="EditPen">重置密码</el-dropdown-item><el-dropdown-item command="logout" :icon="SwitchButton">退出登录</el-dropdown-item>
</el-dropdown-menu>

2. 添加退出功能

const onCommand = async (command) => {if (command === 'logout') {await ElMessageBox.confirm('你确认退出大事件吗？', '温馨提示', {type: 'warning',confirmButtonText: '确认',cancelButtonText: '取消'})userStore.removeToken()userStore.setUser({})router.push(`/login`) //反引号} else {router.push(`/user/${command}`) //反引号}
}

3. pinia user.js 模块 提供 setUser 方法

const setUser = (obj) => (user.value = obj)
