## 4. 核心模块设计

### 4.1 认证模块

#### 4.1.1 认证Store
```typescript
// 认证状态管理
export const useAuthStore = defineStore('auth', () => {
  // 状态
  const token = ref<string>('')
  const userInfo = ref<AdminUser | null>(null)
  const permissions = ref<string[]>([])
  const roles = ref<string[]>([])
  
  // Getters
  const isLogin = computed(() => !!token.value)
  const hasPermission = computed(() => (permission: string) => 
    permissions.value.includes(permission)
  )
  const hasRole = computed(() => (role: string) => 
    roles.value.includes(role)
  )
  
  // Actions
  const login = async (credentials: LoginCredentials) => {
    try {
      const response = await authApi.login(credentials)
      
      token.value = response.token
      userInfo.value = response.userInfo
      permissions.value = response.permissions
      roles.value = response.roles
      
      // 保存到本地存储
      localStorage.setItem('admin_token', response.token)
      localStorage.setItem('admin_user', JSON.stringify(response.userInfo))
      
      return response
    } catch (error) {
      throw error
    }
  }
  
  const logout = async () => {
    try {
      await authApi.logout()
    } finally {
      // 清除状态
      token.value = ''
      userInfo.value = null
      permissions.value = []
      roles.value = []
      
      // 清除本地存储
      localStorage.removeItem('admin_token')
      localStorage.removeItem('admin_user')
      
      // 跳转到登录页
      router.push('/login')
    }
  }
  
  const refreshToken = async () => {
    try {
      const response = await authApi.refreshToken()
      token.value = response.token
      localStorage.setItem('admin_token', response.token)
      return response.token
    } catch (error) {
      await logout()
      throw error
    }
  }
  
  const initAuth = () => {
    const savedToken = localStorage.getItem('admin_token')
    const savedUser = localStorage.getItem('admin_user')
    
    if (savedToken && savedUser) {
      token.value = savedToken
      userInfo.value = JSON.parse(savedUser)
    }
  }
  
  return {
    // State
    token: readonly(token),
    userInfo: readonly(userInfo),
    permissions: readonly(permissions),
    roles: readonly(roles),
    
    // Getters
    isLogin,
    hasPermission,
    hasRole,
    
    // Actions
    login,
    logout,
    refreshToken,
    initAuth
  }
})
```

#### 4.1.2 路由守卫
```typescript
// 路由守卫
import { useAuthStore } from '@/stores/modules/auth'

export function setupRouterGuards(router: Router) {
  // 全局前置守卫
  router.beforeEach(async (to, from, next) => {
    const authStore = useAuthStore()
    
    // 白名单路由
    const whiteList = ['/login', '/404', '/403']
    
    if (whiteList.includes(to.path)) {
      next()
      return
    }
    
    // 检查登录状态
    if (!authStore.isLogin) {
      next('/login')
      return
    }
    
    // 检查权限
    if (to.meta.permission && !authStore.hasPermission(to.meta.permission)) {
      next('/403')
      return
    }
    
    // 检查角色
    if (to.meta.roles && !to.meta.roles.some(role => authStore.hasRole(role))) {
      next('/403')
      return
    }
    
    next()
  })
  
  // 全局后置守卫
  router.afterEach((to) => {
    // 设置页面标题
    document.title = `${to.meta.title || '管理后台'} - 解班客`
    
    // 页面访问统计
    // analytics.trackPageView(to.path)
  })
}
```

## 5. 权限管理

### 5.1 权限设计

#### 5.1.1 权限模型
```typescript
// 权限类型定义
interface Permission {
  id: string
  name: string
  code: string
  type: 'menu' | 'button' | 'api'
  resource: string
  action: string
  description?: string
}

interface Role {
  id: string
  name: string
  code: string
  permissions: Permission[]
  description?: string
}

interface AdminUser {
  id: string
  username: string
  email: string
  roles: Role[]
  permissions: Permission[]
  status: 'active' | 'inactive'
}
```

#### 5.1.2 权限指令
```typescript
// 权限指令
import type { App, DirectiveBinding } from 'vue'
import { useAuthStore } from '@/stores/modules/auth'

export function setupPermissionDirective(app: App) {
  // v-permission 指令
  app.directive('permission', {
    mounted(el: HTMLElement, binding: DirectiveBinding) {
      const { value } = binding
      const authStore = useAuthStore()
      
      if (value && !authStore.hasPermission(value)) {
        el.style.display = 'none'
      }
    },
    
    updated(el: HTMLElement, binding: DirectiveBinding) {
      const { value } = binding
      const authStore = useAuthStore()
      
      if (value && !authStore.hasPermission(value)) {
        el.style.display = 'none'
      } else {
        el.style.display = ''
      }
    }
  })
  
  // v-role 指令
  app.directive('role', {
    mounted(el: HTMLElement, binding: DirectiveBinding) {
      const { value } = binding
      const authStore = useAuthStore()
      
      const hasRole = Array.isArray(value) 
        ? value.some(role => authStore.hasRole(role))
        : authStore.hasRole(value)
      
      if (!hasRole) {
        el.style.display = 'none'
      }
    }
  })
}
```

#### 5.1.3 权限组件
```vue
<!-- PermissionWrapper.vue -->
<template>
  <div v-if="hasAccess">
    <slot />
  </div>
  <div v-else-if="showFallback">
    <slot name="fallback">
      <div class="no-permission">
        <el-empty description="暂无权限访问" />
      </div>
    </slot>
  </div>
</template>

<script setup lang="ts">
interface Props {
  permission?: string | string[]
  role?: string | string[]
  showFallback?: boolean
}

const props = withDefaults(defineProps<Props>(), {
  showFallback: false
})

const authStore = useAuthStore()

const hasAccess = computed(() => {
  // 检查权限
  if (props.permission) {

```

### 5.2 菜单权限

#### 5.2.1 动态菜单
```typescript
// 菜单配置
export interface MenuItem {

    id: 'user',
    title: '用户管理',
    icon: 'User',
    permission: 'user:view',
    children: [
      {
        id: 'user-list',
        title: '用户列表',
        path: '/user/list',
        permission: 'user:list'
      },
      {
        id: 'user-role',
        title: '角色管理',
        path: '/user/role',
        permission: 'user:role'
      }
    ]
  },
  {
    id: 'travel',
    title: '旅行管理',
    icon: 'Location',
    permission: 'travel:view',
    children: [
      {

        path: '/travel/category',
        permission: 'travel:category'
      }
    ]
  }
]

// 菜单过滤
export function filterMenuByPermission(
  menus: MenuItem[], 
  hasPermission: (permission: string) => boolean,
  hasRole: (role: string) => boolean
): MenuItem[] {
  return menus.filter(menu => {
    // 检查权限
    if (menu.permission && !hasPermission(menu.permission)) {
      return false
    }
    
    // 检查角色
    if (menu.roles && !menu.roles.some(role => hasRole(role))) {
      return false
    }
    
    // 递归过滤子菜单
    if (menu.children) {
      menu.children = filterMenuByPermission(menu.children, hasPermission, hasRole)
    }
    
    return true
  })
}
```

#### 5.2.2 菜单组件
```vue
<!-- SideMenu.vue -->
<template>
  <el-menu
    :default-active="activeMenu"
    :collapse="isCollapse"
    :unique-opened="true"
    router
  >
    <menu-item
      v-for="menu in filteredMenus"
      :key="menu.id"

defineProps<Props>()

const route = useRoute()
const authStore = useAuthStore()

// 当前激活菜单

// 过滤后的菜单
const filteredMenus = computed(() => {
  return filterMenuByPermission(
    menuConfig,
    authStore.hasPermission,
    authStore.hasRole
  )
})
</script>
```

## 6. 性能优化

### 6.1 代码分割

#### 6.1.1 路由懒加载
```typescript
// 路由配置
const routes: RouteRecordRaw[] = [
  {
    path: '/dashboard',
    name: 'Dashboard',
    component: () => import('@/views/dashboard/index.vue'),
    meta: {
      title: '仪表板',
      permission: 'dashboard:view'
    }
  },
  {
    path: '/user',
    name: 'User',
    component: () => import('@/views/user/index.vue'),
    meta: {
      title: '用户管理',
      permission: 'user:view'
    },
    children: [
      {
        path: 'list',
        name: 'UserList',
        component: () => import('@/views/user/list.vue'),
        meta: {
          title: '用户列表',
          permission: 'user:list'
        }
      }
    ]
  }
]
```

#### 6.1.2 组件懒加载
```typescript
// 异步组件
import { defineAsyncComponent } from 'vue'

export const AsyncDataTable = defineAsyncComponent({
  loader: () => import('@/components/DataTable.vue'),
  loadingComponent: () => h('div', '加载中...'),
  errorComponent: () => h('div', '加载失败'),
  delay: 200,
  timeout: 3000
})
```

### 6.2 缓存优化

#### 6.2.1 组件缓存
```vue
<!-- 页面缓存 -->
<template>
  <router-view v-slot="{ Component, route }">
    <keep-alive :include="cachedViews">
      <component :is="Component" :key="route.path" />
    </keep-alive>
  </router-view>
</template>

<script setup lang="ts">
// 缓存的页面组件
const cachedViews = ref(['UserList', 'TravelList'])
</script>
```

#### 6.2.2 数据缓存
```typescript
// 数据缓存Hook
export function useCache<T>(
  key: string,
  fetcher: () => Promise<T>,
  options: {
    ttl?: number // 缓存时间（毫秒）
    staleWhileRevalidate?: boolean // 后台更新
  } = {}
) {
  const { ttl = 5 * 60 * 1000, staleWhileRevalidate = true } = options
  
  const data = ref<T>()
  const loading = ref(false)
  const error = ref<Error>()
  
  const cacheKey = `cache_${key}`
  
  // 从缓存获取数据
  const getFromCache = (): { data: T; timestamp: number } | null => {
    try {
      const cached = localStorage.getItem(cacheKey)
      return cached ? JSON.parse(cached) : null
    } catch {
      return null
    }
  }
  
  // 保存到缓存
  const saveToCache = (value: T) => {
    try {
      localStorage.setItem(cacheKey, JSON.stringify({
        data: value,
        timestamp: Date.now()
      }))
    } catch {
      // 忽略存储错误
    }
  }
  
  // 检查缓存是否过期
  const isCacheExpired = (timestamp: number): boolean => {
    return Date.now() - timestamp > ttl
  }
  
  // 获取数据
  const fetchData = async (useCache = true): Promise<T> => {
    // 检查缓存
    if (useCache) {
      const cached = getFromCache()
      if (cached && !isCacheExpired(cached.timestamp)) {
        data.value = cached.data
        
        // 后台更新
        if (staleWhileRevalidate) {
          fetchData(false).catch(() => {})
        }
        
        return cached.data
      }
    }
    
    // 获取新数据
    loading.value = true
    error.value = undefined
    
    try {
      const result = await fetcher()
      data.value = result
      saveToCache(result)
      return result
    } catch (err) {
      error.value = err as Error
      throw err
    } finally {
      loading.value = false
    }
  }
  
  // 清除缓存
  const clearCache = () => {
    localStorage.removeItem(cacheKey)
  }
  
  return {
    data: readonly(data),
    loading: readonly(loading),
    error: readonly(error),
    fetchData,
    clearCache
  }
}

const scrollTop = ref(0)

// 计算属性
const totalHeight = computed(() => props.items.length * props.itemHeight)

const visibleCount = computed(() => 
  Math.ceil(props.containerHeight / props.itemHeight)
)

describe('DataTable', () => {
  const mockData = [
    { id: 1, name: 'John', age: 25 },
    { id: 2, name: 'Jane', age: 30 }
  ]
  
  const mockColumns = [
    { prop: 'name', label: '姓名' },
    { prop: 'age', label: '年龄' }
  ]
  
  it('renders table with data', () => {
    const wrapper = mount(DataTable, {
      props: {
        data: mockData,
        columns: mockColumns
      }
    })
    
    expect(wrapper.find('.el-table').exists()).toBe(true)

    const wrapper = mount(UserList, {
      global: {
        plugins: [
          createTestingPinia({
            createSpy: vi.fn
          })
        ]
      }
    })
    
    // 等待数据加载
    await wrapper.vm.$nextTick()
    
    expect(wrapper.find('.user-list').exists()).toBe(true)
