+# useAuthError.ts
+
+**路径**：`src/composables/useAuthError.ts`
+
+## 功能用途
+
+统一处理 HTTP 401（Unauthorized）等权限相关错误，根据登录状态返回用户友好的提示文案：未登录时提示「请先登录」，已登录时提示「权限不足」。
+
+## 核心能力
+
+- `formatAuthError(err, fallback)`：将异常转换为展示文案
+  - 若错误信息包含 `401` 或 `Unauthorized`：根据 `userStore.isLoggedIn` 返回 `error.pleaseLogin` 或 `error.insufficientPermission`
+  - 否则返回原始错误信息或 `fallback`
+
+## 使用方式
+
+```typescript
+import { useAuthError } from '@/composables/useAuthError'
+
+const { formatAuthError } = useAuthError()
+
+try {
+  await someApiCall()
+} catch (e) {
+  errorMessage.value = formatAuthError(e, t('error.requestFailed'))
+}
+```
+
+## 国际化
+
+依赖 `error.pleaseLogin`、`error.insufficientPermission`，在各 `locales/*.json` 的 `error` 下配置。
+
+## 扩展方式
+
+1. **扩展状态码**：在 `formatAuthError` 中增加对 403 等的判断
+2. **统一拦截**：在 `request.ts` 层统一处理 401，自动跳转登录或弹 toast
