-```
-
-### 直接使用 golangci-lint
-
-```bash
-# 基本檢查
-golangci-lint run
-
-# 自動修復
-golangci-lint run --fix
-
-# 檢查特定目錄
-golangci-lint run ./pkg/...
-
-# 詳細輸出
-golangci-lint run -v
-
-# 只顯示新問題
-golangci-lint run --new-from-rev=main
-```
-
-## 配置說明
-
-### 啟用的 Linters
-
-我們的配置啟用了以下 linter 類別：
-
-#### 核心檢查
-- `errcheck`: 檢查未處理的錯誤
-- `gosimple`: 簡化代碼建議
-- `govet`: 檢查常見錯誤
-- `staticcheck`: 靜態分析
-- `typecheck`: 類型檢查
-- `unused`: 檢查未使用的變量和函數
-
-#### 代碼質量
-- `cyclop`: 循環複雜度檢查
-- `dupl`: 代碼重複檢測
-- `funlen`: 函數長度檢查
-- `gocognit`: 認知複雜度檢查
-- `gocyclo`: 循環複雜度檢查
-- `nestif`: 嵌套深度檢查
-
-#### 格式化
-- `gofmt`: 格式化檢查
-- `gofumpt`: 更嚴格的格式化
-- `goimports`: 導入排序
-
-#### 命名和風格
-- `goconst`: 常量檢查
-- `gocritic`: 代碼評論
-- `gomnd`: 魔術數字檢查
-- `stylecheck`: 風格檢查
-- `varnamelen`: 變量名長度檢查
-
-#### 安全
-- `gosec`: 安全檢查
-
-#### 錯誤處理
-- `errorlint`: 錯誤處理檢查
-- `nilerr`: nil 錯誤檢查
-- `wrapcheck`: 錯誤包裝檢查
-
-### 配置文件結構
-
-```yaml
-# .golangci.yml
-run:
-  timeout: 5m
-  skip-dirs: [vendor, .git, bin, build, dist, tmp]
-  skip-files: [".*\\.pb\\.go$", ".*\\.gen\\.go$"]
-
-linters:
-  disable-all: true
-  enable: [errcheck, gosimple, govet, ...]
-
-linters-settings:
-  # 各個 linter 的詳細配置
-  
-issues:
-  # 問題排除規則
-  exclude-rules:
-    - path: _test\.go
-      linters: [gomnd, funlen, dupl]
-```
-
-## IDE 整合
-
-### VS Code
-項目包含 `.vscode/settings.json` 配置：
-- 自動使用 golangci-lint 進行檢查
-- 保存時自動格式化
-- 使用 gofumpt 作為格式化工具
-
-### GoLand/IntelliJ
-1. 安裝 golangci-lint 插件
-2. 在設置中指向項目的 `.golangci.yml` 文件
-
-## CI/CD 整合
-
-### GitHub Actions
-項目包含 `.github/workflows/ci.yml`：
-- 自動運行測試
-- 執行 golangci-lint 檢查
-- 安全掃描
-- 依賴檢查
-
-### 本地 Git Hooks
-可以設置 pre-commit hook：
-
-```bash
-#!/bin/sh
-# .git/hooks/pre-commit
-make lint
-```
-
-## 常見問題
-
-### 1. 如何忽略特定的檢查？
-
-在代碼中使用註釋：
-```go
-//nolint:gosec // 忽略安全檢查
-password := "hardcoded"
-
-//nolint:lll // 忽略行長度檢查
-url := "https://very-long-url-that-exceeds-line-length-limit.com/api/v1/endpoint"
-```
-
-### 2. 如何為測試文件設置不同的規則？
-
-配置文件中已經為測試文件設置了特殊規則：
-```yaml
-exclude-rules:
-  - path: _test\.go
-    linters: [gomnd, funlen, dupl, lll, goconst]
-```
-
-### 3. 如何調整複雜度閾值？
-
-在 `.golangci.yml` 中調整：
-```yaml
-linters-settings:
-  cyclop:
-    max-complexity: 15  # 調整循環複雜度
-  funlen:
-    lines: 100          # 調整函數行數限制
-    statements: 50      # 調整語句數限制
-```
-
-### 4. 性能優化
-
-- 使用緩存：`golangci-lint cache clean` 清理緩存
-- 只檢查修改的文件：`--new-from-rev=main`
-- 並行執行：默認已啟用
-
-## 升級和維護
-
-定期更新 golangci-lint：
-```bash
-# 檢查版本
-golangci-lint version
-
-# 升級到最新版本
-brew upgrade golangci-lint  # macOS
-# 或重新下載安裝腳本
-```
-
-定期檢查配置文件的新選項和 linter：
-```bash
-# 查看所有可用的 linter
-golangci-lint linters
-
-# 查看配置幫助
-golangci-lint config -h
-```

 ## 🚀 快速開始
 
-### 1. 配置設定
+### 1. 安裝依賴
 
-在 `internal/config/config.go` 中添加 Token 配置：
+```bash
-
+go get backend/pkg/permission
-```go
-type Config struct {
-    // ... 其他配置
-    
-    Token struct {
-        AccessSecret         string        // Access Token 簽名密鑰
-        RefreshSecret        string        // Refresh Token 簽名密鑰
-        AccessTokenExpiry    time.Duration // Access Token 過期時間
-        RefreshTokenExpiry   time.Duration // Refresh Token 過期時間
-        OneTimeTokenExpiry   time.Duration // 一次性 Token 過期時間
-        MaxTokensPerUser     int           // 每用戶最大 Token 數
-        MaxTokensPerDevice   int           // 每設備最大 Token 數

+## 💡 最佳實踐
+
+### 1. 令牌管理
+
+#### ✅ 推薦做法
 ```go
-type TokenUseCase interface {
+// 使用 Refresh Token 自動刷新
-    // 基本 Token 操作
+if tokenUC.IsAccessTokenValid(ctx, accessToken) {
-    NewToken(ctx context.Context, req entity.AuthorizationReq) (entity.TokenResp, error)
+    // 使用令牌
-    RefreshToken(ctx context.Context, req entity.RefreshTokenReq) (entity.RefreshTokenResp, error)
+} else {
-    ValidationToken(ctx context.Context, req entity.ValidationTokenReq) (entity.ValidationTokenResp, error)
+    // 嘗試刷新
-    
+    newToken, err := tokenUC.RefreshToken(ctx, refreshReq)
-    // Token 管理
+    if err != nil {
-    CancelToken(ctx context.Context, req entity.CancelTokenReq) error
+        // 要求重新登錄
-    CancelTokens(ctx context.Context, req entity.DoTokenByUIDReq) error
+    }
-    CancelTokenByDeviceID(ctx context.Context, req entity.DoTokenByDeviceIDReq) error
-    
-    // 查詢操作
-    GetUserTokensByUID(ctx context.Context, req entity.QueryTokenByUIDReq) ([]*entity.TokenResp, error)
-    GetUserTokensByDeviceID(ctx context.Context, req entity.DoTokenByDeviceIDReq) ([]*entity.TokenResp, error)
-    
-    // 一次性 Token
-    NewOneTimeToken(ctx context.Context, req entity.CreateOneTimeTokenReq) (entity.CreateOneTimeTokenResp, error)
-    CancelOneTimeToken(ctx context.Context, req entity.CancelOneTimeTokenReq) error
-    
-    // 黑名單操作
-    BlacklistToken(ctx context.Context, token string, reason string) error
-    IsTokenBlacklisted(ctx context.Context, jti string) (bool, error)
-    BlacklistAllUserTokens(ctx context.Context, uid string, reason string) error
-    
-    // 工具方法
-    ReadTokenBasicData(ctx context.Context, token string) (map[string]string, error)
 }
 ```
 
-### 主要實體
+#### ❌ 避免做法
-
-#### Token 實體
 ```go
-type Token struct {
+// 不要在每次請求都生成新令牌
-    ID                  string    // 權杖唯一標識
+// 不要將令牌存儲在不安全的地方
-    UID                 string    // 用戶 ID
+// 不要在客戶端解析 Refresh Token
-    DeviceID            string    // 設備 ID
+```
-    AccessToken         string    // Access Token
+
-    RefreshToken        string    // Refresh Token
+### 2. 權限檢查
-    ExpiresIn           int       // 過期時間（秒）
+
-    AccessCreateAt      time.Time // Access Token 創建時間
+#### ✅ 推薦做法
-    RefreshCreateAt     time.Time // Refresh Token 創建時間
+```go
-    RefreshExpiresIn    int       // Refresh Token 過期時間（秒）
+// 使用權限檢查中間件
+func AuthMiddleware(rolePermUC usecase.RolePermissionUseCase) gin.HandlerFunc {
+    return func(c *gin.Context) {
+        roleUID := c.GetString("role_uid")
+        result, err := rolePermUC.CheckPermission(
+            c.Request.Context(),
+            roleUID,
+            c.Request.URL.Path,
+            c.Request.Method,
+        )
+        
+        if err != nil || !result.Allowed {
+            c.AbortWithStatus(http.StatusForbidden)
+            return
+        }
+        
+        c.Next()
+    }
 }
 ```
 
-#### 黑名單實體
+#### ❌ 避免做法
 ```go
-type BlacklistEntry struct {
+// 不要在每個 Handler 中重複權限檢查代碼
-    JTI       string // JWT ID
+// 不要硬編碼權限名稱
-    UID       string // 用戶 ID
+// 不要跳過權限檢查
-    TokenID   string // Token ID
+```
-    Reason    string // 加入黑名單原因
+
-    ExpiresAt int64  // 原始權杖過期時間
+### 3. 權限設計
-    CreatedAt int64  // 加入黑名單時間
+
+#### ✅ 推薦做法
+```go
+// 使用層級式權限結構
+// 例如：
+// - user
+//   - user.list
+//   - user.create
+//   - user.update
+//   - user.delete
+
+// 父權限會自動包含，只需設置子權限即可
+perms := permission.Permissions{
+    "user.list": permission.Open,
+}
+// 展開後會自動包含 "user"
+```
+
+#### ❌ 避免做法
+```go
+// 不要創建過深的權限層級（建議 ≤ 3 層）
+// 不要使用過於細緻的權限粒度
+// 不要創建循環依賴的權限
+```
+
+### 4. 角色管理
+
+#### ✅ 推薦做法
+```go
+// 使用預定義角色
+const (
+    RoleAdmin     = "ADMIN"
+    RoleManager   = "MANAGER"
+    RoleEmployee  = "EMPLOYEE"
+)
+
+// 定期檢查無使用者的角色
+roles, _ := roleUC.Page(ctx, filter, 1, 100)
+for _, role := range roles.List {
+    if role.UserCount == 0 {
+        // 考慮刪除或停用
+    }
 }
 ```
 
-## 🔧 配置參數
+#### ❌ 避免做法
-
-| 參數 | 類型 | 說明 | 預設值 |
-|------|------|------|--------|
-| `AccessSecret` | string | Access Token 簽名密鑰 | 必填 |
-| `RefreshSecret` | string | Refresh Token 簽名密鑰 | 必填 |
-| `AccessTokenExpiry` | Duration | Access Token 過期時間 | 15分鐘 |
-| `RefreshTokenExpiry` | Duration | Refresh Token 過期時間 | 7天 |
-| `OneTimeTokenExpiry` | Duration | 一次性 Token 過期時間 | 5分鐘 |
-| `MaxTokensPerUser` | int | 每用戶最大 Token 數 | 10 |
-| `MaxTokensPerDevice` | int | 每設備最大 Token 數 | 5 |

-## 🚨 錯誤處理
-
-模組定義了完整的錯誤類型：
-
 ```go
-// Token 驗證錯誤
+// 不要創建過多的角色
-var (
+// 不要刪除有使用者的角色
-    ErrInvalidTokenID     = errors.New("invalid token ID")
+// 不要頻繁修改角色權限
-    ErrInvalidUID         = errors.New("invalid UID")
-    ErrTokenExpired       = errors.New("token expired")
-    ErrTokenNotFound      = errors.New("token not found")
-)
-
-// JWT 特定錯誤
-var (
-    ErrInvalidJWTToken    = errors.New("invalid JWT token")
-    ErrJWTSigningFailed   = errors.New("JWT signing failed")
-    ErrJWTParsingFailed   = errors.New("JWT parsing failed")
-)
-
-// 黑名單錯誤
-var (
-    ErrTokenBlacklisted   = errors.New("token is blacklisted")
-    ErrBlacklistNotFound  = errors.New("blacklist entry not found")
-)
 ```
 
-## 🔒 安全考量
+## 🔐 安全建議
 
-### 1. 密鑰管理
+1. **JWT 密鑰管理**
-- 使用強密鑰（至少 256 位）
+   - 使用強密鑰（至少 32 字元）
-- Access Token 和 Refresh Token 使用不同密鑰
    - 定期輪換密鑰
+   - 不要將密鑰硬編碼在代碼中
 
-### 2. 權杖過期
+2. **令牌過期設置**
-- Access Token 使用較短過期時間（15分鐘）
+   - Access Token: 15 分鐘 - 1 小時
-- Refresh Token 使用較長過期時間（7天）
+   - Refresh Token: 7 - 30 天
-- 支援自定義過期時間
+   - One-Time Token: 5 - 10 分鐘
 
-### 3. 黑名單機制
+3. **設備追蹤**
-- 即時撤銷可疑權杖
+   - 啟用設備指紋追蹤
-- 支援批量撤銷
+   - 限制每個設備的令牌數量
-- 自動清理過期條目
+   - 檢測異常登錄行為
 
-### 4. 限制機制
+4. **權限檢查**
-- 每用戶權杖數量限制
+   - 在所有 API 端點進行權限檢查
-- 每設備權杖數量限制
+   - 使用白名單而非黑名單
-- 防止權杖濫用
+   - 記錄權限拒絕事件
 
-## 📈 效能優化
+## 📝 資料庫設計
 
-### 1. Redis 優化
+### MongoDB Collections
-- 使用適當的 TTL 避免記憶體洩漏
-- 批量操作減少網路往返
-- 使用 Pipeline 提升效能
 
-### 2. JWT 優化

+  "create_time": 1234567890,
+  "update_time": 1234567890
+}
+```
 
-### 3. 黑名單優化
+#### roles
-- 使用 SCAN 而非 KEYS 遍歷
+```json
