+
+## 🔧 集成步骤
+
+### 步骤 1: 环境配置
+
+1. 复制环境变量模板：
+```bash
+cp .env.example .env
+```
+
+2. 生成密钥并填写 `.env`：
+```bash
+# JWT 密钥
+openssl rand -hex 32
+
+# 加密密钥
+python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+```
+
+3. 编辑 `.env` 填写所有必需的配置项。
+
+### 步骤 2: 数据库迁移
+
+执行数据库迁移脚本：
+
+```bash
+# 方法 1: 使用 psql 命令
+psql -U postgres -d tjwater -f migrations/001_create_users_table.sql
+psql -U postgres -d tjwater -f migrations/002_create_audit_logs_table.sql
+
+# 方法 2: 在 psql 交互界面
+psql -U postgres -d tjwater
+\i migrations/001_create_users_table.sql
+\i migrations/002_create_audit_logs_table.sql
+```
+
+验证表已创建：
+
+```sql
+-- 检查用户表
+SELECT * FROM users;
+
+-- 检查审计日志表
+SELECT * FROM audit_logs;
+```
+
+### 步骤 3: 更新 main.py
+
+在 `app/main.py` 中集成新功能：
+
+```python
+from fastapi import FastAPI
+from app.core.config import settings
+from app.infra.audit.middleware import AuditMiddleware
+
+app = FastAPI(title=settings.PROJECT_NAME)
+
+# 1. 添加审计中间件（可选）
+app.add_middleware(AuditMiddleware)
+
+# 2. 注册路由
+from app.api.v1.endpoints import auth, user_management, audit
+
+app.include_router(
+    auth.router,
+    prefix=f"{settings.API_V1_STR}/auth",
+    tags=["认证"]
+)
+
+app.include_router(
+    user_management.router,
+    prefix=f"{settings.API_V1_STR}/users",
+    tags=["用户管理"]
+)
+
+app.include_router(
+    audit.router,
+    prefix=f"{settings.API_V1_STR}/audit",
+    tags=["审计日志"]
+)
+
+# 3. 确保数据库在启动时初始化
+@app.on_event("startup")
+async def startup_event():
+    # 初始化数据库连接池
+    from app.infra.db.postgresql.database import Database
+    global db
+    db = Database()
+    db.init_pool()
+    await db.open()
+
+@app.on_event("shutdown")
+async def shutdown_event():
+    # 关闭数据库连接
+    await db.close()
+```
+
+### 步骤 4: 保护现有接口
+
+#### 方法 1: 为路由添加全局依赖
+
+```python
+from app.auth.dependencies import get_current_active_user
+
+# 为整个路由器添加认证
+router = APIRouter(dependencies=[Depends(get_current_active_user)])
+```
+
+#### 方法 2: 为单个端点添加依赖
+
+```python
+from app.auth.permissions import require_role, get_current_admin
+from app.domain.models.role import UserRole
+
+@router.get("/data")
+async def get_data(
+    current_user = Depends(require_role(UserRole.USER))
+):
+    """需要 USER 及以上角色"""
+    return {"data": "protected"}
+
+@router.delete("/data/{id}")
+async def delete_data(
+    id: int,
+    current_user = Depends(get_current_admin)
+):
+    """仅管理员可访问"""
+    return {"message": "deleted"}
+```
+
+### 步骤 5: 添加审计日志
+
+#### 自动审计（推荐）
+
+使用中间件自动记录（已在 main.py 中添加）：
+
+```python
+app.add_middleware(AuditMiddleware)
+```
+
+#### 手动审计
+
+在关键业务逻辑中手动记录：
+
+```python
+from app.core.audit import log_audit_event, AuditAction
+
+@router.post("/important-action")
+async def important_action(
+    data: dict,
+    request: Request,
+    current_user = Depends(get_current_active_user)
+):
+    # 执行业务逻辑
+    result = do_something(data)
+    
+    # 记录审计日志
+    await log_audit_event(
+        action=AuditAction.UPDATE,
+        user_id=current_user.id,
+        username=current_user.username,
+        resource_type="important_resource",
+        resource_id=str(result.id),
+        ip_address=request.client.host,
+        request_data=data
+    )
+    
+    return result
+```
+
+### 步骤 6: 更新 auth/dependencies.py
+
+确保 `get_db()` 函数正确获取数据库实例：
+
+```python
+async def get_db() -> Database:
+    """获取数据库实例"""
+    # 方法 1: 从 main.py 导入
+    from app.main import db
+    return db
+    
+    # 方法 2: 从 FastAPI app.state 获取
+    # from fastapi import Request
+    # def get_db_from_request(request: Request):
+    #     return request.app.state.db
+```
+
+---
+
+## 🧪 测试
+
+### 1. 测试加密功能
+
+```bash
+python tests/test_encryption.py
+```
+
+### 2. 测试 API
+
+启动服务器：
+
+```bash
+uvicorn app.main:app --reload
+```
+
+访问交互式文档：
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
+
+### 3. 测试登录
+
+```bash
+curl -X POST "http://localhost:8000/api/v1/auth/login" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "username=admin&password=admin123"
+```
+
+### 4. 测试受保护接口
+
+```bash
+TOKEN="your-access-token"
+curl -X GET "http://localhost:8000/api/v1/auth/me" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+---
+
+## 🔄 迁移现有接口
+
+### 原有硬编码认证
+
+**旧代码** (`app/api/v1/endpoints/auth.py`):
+```python
+AUTH_TOKEN = "567e33c876a2"
+
+async def verify_token(authorization: str = Header()):
+    token = authorization.split(" ")[1]
+    if token != AUTH_TOKEN:
+        raise HTTPException(status_code=403)
+```
+
+**新代码** (已更新):
+```python
+from app.auth.dependencies import get_current_active_user
+
+@router.get("/protected")
+async def protected_route(
+    current_user = Depends(get_current_active_user)
+):
+    return {"user": current_user.username}
+```
+
+### 更新其他端点
+
+搜索项目中使用旧认证的地方：
+
+```bash
+grep -r "AUTH_TOKEN" app/
+grep -r "verify_token" app/
+```
+
+替换为新的依赖注入系统。

+
+## ⚠️ 注意事项
+
+### 1. 向后兼容性
+
+保留了简化版登录接口 `/auth/login/simple` 以兼容旧客户端：
+
+```python
+@router.post("/login/simple")
+async def login_simple(username: str, password: str):
+    # 验证并返回 Token
+    ...
+```
+
+### 2. 数据库连接
+
+确保在 `app/auth/dependencies.py` 中 `get_db()` 函数能正确获取数据库实例。
+
+### 3. 密钥安全
+
+- ❌ 不要提交 `.env` 文件到版本控制

+## ⚠️ 注意事项
+
+### 1. 审计中间件
+审计中间件默认是**禁用**的。如需启用，在 `app/main.py` 中取消注释：
+
+```python
+app.add_middleware(AuditMiddleware)
+```
+
+**注意**：启用后会自动记录所有 POST/PUT/DELETE 请求，可能增加数据库负载。
+
+### 2. 向后兼容
+保留了原有的简化登录接口 `/auth/login/simple`，可以直接使用查询参数：
+
+```bash
+POST /api/v1/auth/login/simple?username=admin&password=admin123
+```
+
+### 3. 数据库连接
+确保数据库实例在应用启动时正确初始化并存储到 `app.state.db`。
+
+### 4. 权限控制示例
+为现有接口添加权限控制：
+
+```python
+from app.auth.permissions import require_role, get_current_admin
+from app.domain.models.role import UserRole
+
+# 需要管理员权限
+@router.delete("/resource/{id}")
+async def delete_resource(
+    id: int,
+    current_user = Depends(get_current_admin)
+):
+    ...
+
+# 需要操作员以上权限
+@router.post("/resource")
+async def create_resource(
+    data: dict,
+    current_user = Depends(require_role(UserRole.OPERATOR))
+):
+    ...
+```
+
+---
+
+## 🚀 完整启动流程
+
+```bash
+# 1. 进入项目目录

+
+## 🚀 快速开始
+
+### 1. 配置环境变量
+
+复制 `.env.example` 为 `.env` 并配置：
+
+```bash
+cp .env.example .env
+```
+
+生成必要的密钥：
+
+```bash
+# 生成 JWT 密钥
+openssl rand -hex 32
+
+# 生成加密密钥
+python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+```
+
+编辑 `.env` 文件：
+
+```env
+SECRET_KEY=your-generated-jwt-secret-key
+ENCRYPTION_KEY=your-generated-encryption-key
+DB_NAME=tjwater
+DB_HOST=localhost
+DB_PORT=5432
+DB_USER=postgres
+DB_PASSWORD=your-db-password
+```
+
+### 2. 执行数据库迁移
+
+```bash
+# 连接到 PostgreSQL
+psql -U postgres -d tjwater
+
+# 执行迁移脚本
+\i migrations/001_create_users_table.sql
+\i migrations/002_create_audit_logs_table.sql
+```
+
+或使用命令行：
+
+```bash
+psql -U postgres -d tjwater -f migrations/001_create_users_table.sql
+psql -U postgres -d tjwater -f migrations/002_create_audit_logs_table.sql
+```
+
+### 3. 验证安装
+
+默认创建了两个管理员账号：
+
+- **用户名**: `admin` / **密码**: `admin123`
+- **用户名**: `tjwater` / **密码**: `tjwater@123`
+
+---
+
+## 🔐 数据加密
+
+### 使用加密器
+
+```python
+from app.core.encryption import get_encryptor
+
+encryptor = get_encryptor()
+
+# 加密敏感数据
+encrypted_data = encryptor.encrypt("sensitive information")
+
+# 解密
+decrypted_data = encryptor.decrypt(encrypted_data)
+```
+
+### 生成新密钥
+
+```python
+from app.core.encryption import Encryptor
+
+new_key = Encryptor.generate_key()
+print(f"New encryption key: {new_key}")
+```
+
+---
+
+## 👤 身份认证
+
+### 用户角色
+
+系统定义了 4 个角色（权限由低到高）：
+
+| 角色 | 权限说明 |
+|------|---------|
+| `VIEWER` | 仅查询权限 |
+| `USER` | 读写权限 |
+| `OPERATOR` | 操作员，可修改数据 |
+| `ADMIN` | 管理员，完全权限 |
+
+### API 接口
+
+#### 用户注册
+
+```http
+POST /api/v1/auth/register
+Content-Type: application/json
+
+{
+  "username": "newuser",
+  "email": "user@example.com",
+  "password": "password123",
+  "role": "USER"
+}
+```
+
+#### 用户登录（OAuth2 标准）
+
+```http
+POST /api/v1/auth/login
+Content-Type: application/x-www-form-urlencoded
+
+username=admin&password=admin123
+```
+
+响应：
+
+```json
+{
+  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
+  "refresh_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
+  "token_type": "bearer",
+  "expires_in": 1800
+}
+```
+
+#### 用户登录（简化版）
+
+```http
+POST /api/v1/auth/login/simple?username=admin&password=admin123
+```
+
+#### 获取当前用户信息
+
+```http
+GET /api/v1/auth/me
+Authorization: Bearer {access_token}
+```
+
+#### 刷新 Token
+
+```http
+POST /api/v1/auth/refresh
+Content-Type: application/json
+
+{
+  "refresh_token": "your-refresh-token"
+}
+```
+
+---
+
+## 🔑 权限管理
+
+### 在 API 中使用权限控制
+
+#### 方式 1: 使用预定义依赖
+
+```python
+from fastapi import APIRouter, Depends
+from app.auth.permissions import get_current_admin, get_current_operator
+from app.domain.schemas.user import UserInDB
+
+router = APIRouter()
+
+@router.post("/admin-only")
+async def admin_endpoint(
+    current_user: UserInDB = Depends(get_current_admin)
+):
+    """仅管理员可访问"""
+    return {"message": "Admin access granted"}
+
+@router.post("/operator-only")
+async def operator_endpoint(
+    current_user: UserInDB = Depends(get_current_operator)
+):
+    """操作员及以上可访问"""
+    return {"message": "Operator access granted"}
+```
+
+#### 方式 2: 使用 require_role
+
+```python
+from app.auth.permissions import require_role
+from app.domain.models.role import UserRole
+
+@router.get("/viewer-access")
+async def viewer_endpoint(
+    current_user: UserInDB = Depends(require_role(UserRole.VIEWER))
+):
+    """所有认证用户可访问"""
+    return {"data": "visible to all"}
+```
+
+#### 方式 3: 手动检查权限
+
+```python
+from app.auth.dependencies import get_current_active_user
+from app.auth.permissions import check_resource_owner
+
+@router.put("/users/{user_id}")
+async def update_user(
+    user_id: int,
+    current_user: UserInDB = Depends(get_current_active_user)
+):
+    """检查是否是资源拥有者或管理员"""
+    if not check_resource_owner(user_id, current_user):
+        raise HTTPException(status_code=403, detail="Permission denied")
+    
+    # 执行更新操作
+    ...
+```
+
+---
+
+## 📝 审计日志
+
+### 自动审计
+
+使用中间件自动记录关键操作，在 `main.py` 中添加：
+
+```python
+from app.infra.audit.middleware import AuditMiddleware
+
+app.add_middleware(AuditMiddleware)
+```
+
+自动记录：
+- 所有 POST/PUT/DELETE 请求
+- 登录/登出事件
+- 关键资源访问
+
+### 手动记录审计日志
+
+```python
+from app.core.audit import log_audit_event, AuditAction
+
+await log_audit_event(
+    action=AuditAction.UPDATE,
+    user_id=current_user.id,
+    username=current_user.username,
+    resource_type="project",
+    resource_id="123",
+    ip_address=request.client.host,
+    request_data={"field": "value"},
+    response_status=200
+)
+```
+
+### 查询审计日志
+
+#### 获取所有审计日志（仅管理员）
+
+```http
+GET /api/v1/audit/logs?skip=0&limit=100
+Authorization: Bearer {admin_token}
+```
+
+#### 按条件过滤
+
+```http
+GET /api/v1/audit/logs?user_id=1&action=LOGIN&start_time=2024-01-01T00:00:00
+Authorization: Bearer {admin_token}
+```
+
+#### 获取我的操作记录
+
+```http
+GET /api/v1/audit/logs/my
+Authorization: Bearer {access_token}
+```
+
+#### 获取日志总数
+
+```http
+GET /api/v1/audit/logs/count?action=LOGIN
+Authorization: Bearer {admin_token}
+```

+
+## 🛡️ 安全最佳实践
+
+1. **密钥管理**
+   - 绝不在代码中硬编码密钥
+   - 定期轮换 JWT 密钥
+   - 使用强随机密钥
+
+2. **密码策略**
+   - 最小长度 6 个字符（建议 12+）
+   - 强制密码复杂度（可在注册时添加验证）
+   - 定期提醒用户更换密码
+
+3. **Token 管理**
+   - Access Token 短期有效（默认 30 分钟）
+   - Refresh Token 长期有效（默认 7 天）
+   - 实施 Token 黑名单（可选）
+
+4. **审计日志**
+   - 审计日志不可删除
+   - 定期归档旧日志
+   - 监控异常登录行为
+
+5. **权限控制**
+   - 遵循最小权限原则
+   - 定期审查用户权限
+   - 记录所有权限变更

+## ❓ 常见问题
+
+### Q: 忘记密码怎么办？
+
+A: 目前需要管理员通过数据库重置。未来可添加邮件重置功能。
+
+```sql
+-- 重置密码为 "newpassword123"
+UPDATE users 
+SET hashed_password = '$2b$12$...' -- 使用 bcrypt 生成哈希
+WHERE username = 'targetuser';
+```
+
+### Q: 如何添加新角色？
+
+A: 编辑 `app/domain/models/role.py` 中的 `UserRole` 枚举，并更新数据库约束。
+
+### Q: 审计日志占用太多空间？
+
+A: 建议定期归档旧日志到冷存储：
+
+```sql
+-- 归档 90 天前的日志
+CREATE TABLE audit_logs_archive AS
+SELECT * FROM audit_logs WHERE timestamp < NOW() - INTERVAL '90 days';
+
+DELETE FROM audit_logs WHERE timestamp < NOW() - INTERVAL '90 days';
+```
