+   {
+     "username": "testuser",
+     "password": "password123",
+     "nickname": "测试用户",
+     "email": "user@example.com",
+     "email_verification_code": "123456"
+   }
+   ```
+
+### 独立邮箱验证
+
+1. **验证邮箱**
+   ```typescript
+   POST /auth/verify-email
+   {
+     "email": "user@example.com",
+     "verification_code": "123456"
+   }
+   ```
+
+## 配置说明
+
+### 环境变量
+
+```bash
+# 邮件服务配置
+SMTP_HOST=smtp.example.com
+SMTP_PORT=587

+
+### 验证码配置
+
+```typescript
+// 验证码长度
+CODE_LENGTH = 6
+
+// 验证码过期时间（秒）
+CODE_EXPIRE_TIME = 300 // 5分钟
+
+// 最大验证尝试次数
+MAX_ATTEMPTS = 3
+
+// 发送冷却时间（秒）
+RATE_LIMIT_TIME = 60 // 1分钟
+
+// 每小时最大发送次数
+MAX_SENDS_PER_HOUR = 5
+```
+
+## API接口
+
+### 发送邮箱验证码
+
+- **接口**：`POST /auth/send-email-verification`
+- **描述**：向指定邮箱发送验证码
+- **参数**：

+pnpm install ioredis nodemailer
+
+# 安装类型定义
+pnpm install -D @types/nodemailer
+```
+
+## 2. Redis 服务配置
+
+### 2.1 安装 Redis
+
+#### Ubuntu/Debian
+```bash
+sudo apt update
+sudo apt install redis-server
+sudo systemctl start redis-server
+sudo systemctl enable redis-server
+```
+
+#### CentOS/RHEL
+```bash
+sudo yum install redis
+sudo systemctl start redis
+sudo systemctl enable redis
+```
+
+#### Docker 方式
+```bash
+docker run -d --name redis -p 6379:6379 redis:7-alpine
+```
+
+### 2.2 Redis 配置验证
+
+```bash
+# 测试 Redis 连接
+redis-cli ping
+# 应该返回 PONG
+```
+
+## 3. 邮件服务配置
+
+### 3.1 Gmail 配置示例
+
+1. **启用两步验证**：
+   - 登录 Google 账户
+   - 进入"安全性"设置
+   - 启用"两步验证"
+
+2. **生成应用专用密码**：
+   - 在"安全性"设置中找到"应用专用密码"
+   - 生成新的应用密码
+   - 记录生成的16位密码
+
+3. **环境变量配置**：
+```env
+EMAIL_HOST=smtp.gmail.com
+EMAIL_PORT=587
+EMAIL_SECURE=false
+EMAIL_USER=your-email@gmail.com
+EMAIL_PASS=your-16-digit-app-password
+EMAIL_FROM="Whale Town Game" <noreply@gmail.com>
+```
+
+### 3.2 其他邮件服务商配置
+
+#### 163邮箱
+```env
+EMAIL_HOST=smtp.163.com
+EMAIL_PORT=587
+EMAIL_SECURE=false
+EMAIL_USER=your-email@163.com
+EMAIL_PASS=your-authorization-code
+```
+
+#### QQ邮箱
+```env
+EMAIL_HOST=smtp.qq.com
+EMAIL_PORT=587
+EMAIL_SECURE=false
+EMAIL_USER=your-email@qq.com
+EMAIL_PASS=your-authorization-code
+```
+
+#### 阿里云邮件推送
+```env
+EMAIL_HOST=smtpdm.aliyun.com
+EMAIL_PORT=587
+EMAIL_SECURE=false
+EMAIL_USER=your-smtp-username
+EMAIL_PASS=your-smtp-password
+```
+
+## 4. 环境变量配置
+
+### 4.1 创建环境配置文件
+
+```bash
+# 复制环境变量模板
+cp .env.production.example .env
+
+# 编辑环境变量
+nano .env
+```
+
+### 4.2 完整的环境变量配置
+
+```env
+# 数据库配置
+DB_HOST=localhost
+DB_PORT=3306
+DB_USERNAME=pixel_game
+DB_PASSWORD=your_db_password
+DB_NAME=pixel_game_db
+
+# 应用配置
+NODE_ENV=production
+PORT=3000
+
+# JWT 配置
+JWT_SECRET=your_jwt_secret_key_here_at_least_32_characters
+JWT_EXPIRES_IN=7d
+

+EMAIL_PASS=your-app-password
+EMAIL_FROM="Whale Town Game" <noreply@whaletown.com>
+```
+
+## 5. 数据库迁移
+
+由于添加了新的字段，需要更新数据库结构：
+
+```sql
+-- 添加邮箱验证状态字段
+ALTER TABLE users ADD COLUMN email_verified BOOLEAN NOT NULL DEFAULT FALSE COMMENT '邮箱是否已验证';
+
+-- 为已有用户设置默认值
+UPDATE users SET email_verified = FALSE WHERE email_verified IS NULL;
+
+-- 如果是OAuth用户且有邮箱，可以设为已验证
+UPDATE users SET email_verified = TRUE WHERE github_id IS NOT NULL AND email IS NOT NULL;
+```
+
+## 6. 启动和测试
+
+### 6.1 启动应用
+
+```bash
+# 安装依赖
+pnpm install
+
+# 构建应用

+# Redis 适配器
+
+这个Redis适配器提供了一个统一的接口，可以在本地开发环境使用文件存储模拟Redis，在生产环境使用真实的Redis服务。
+
+## 功能特性
+
+- 🔄 **自动切换**: 根据环境变量自动选择文件存储或真实Redis
+- 📁 **文件存储**: 本地开发时使用JSON文件模拟Redis功能
+- ⚡ **真实Redis**: 生产环境连接真实Redis服务器
+- 🕒 **过期支持**: 完整支持TTL和自动过期清理
+- 🔒 **类型安全**: 使用TypeScript接口确保类型安全
+- 📊 **日志记录**: 详细的操作日志和错误处理
+
+## 环境配置
+
+### 开发环境 (.env)
+```bash
+# 使用文件模拟Redis
+USE_FILE_REDIS=true
+NODE_ENV=development
+
+# Redis配置（文件模式下不会使用）
+REDIS_HOST=localhost
+REDIS_PORT=6379
+REDIS_PASSWORD=
+REDIS_DB=0
+```
+
+### 生产环境 (.env.production)
+```bash
+# 使用真实Redis
+USE_FILE_REDIS=false
+NODE_ENV=production
+
+# Redis服务器配置
+REDIS_HOST=your_redis_host
+REDIS_PORT=6379
+REDIS_PASSWORD=your_redis_password
+REDIS_DB=0
+```
+
+## 使用方法
+
+### 1. 在模块中导入
+```typescript
+import { Module } from '@nestjs/common';
+import { RedisModule } from './core/redis/redis.module';
+
+@Module({
+  imports: [RedisModule],
+  // ...
+})
+export class YourModule {}
+```
+
+### 2. 在服务中注入
+```typescript
+import { Injectable, Inject } from '@nestjs/common';
+import { IRedisService } from './core/redis/redis.interface';
+
+@Injectable()
+export class YourService {
+  constructor(
+    @Inject('REDIS_SERVICE') private readonly redis: IRedisService,
+  ) {}
+
+  async example() {
+    // 设置键值对，30秒后过期
+    await this.redis.set('user:123', 'user_data', 30);
+    
+    // 获取值
+    const value = await this.redis.get('user:123');
+    
+    // 检查是否存在
+    const exists = await this.redis.exists('user:123');
+    
+    // 删除键
+    await this.redis.del('user:123');
+  }
+}
+```
+
+## API 接口
+
+### set(key, value, ttl?)
+设置键值对，可选过期时间
+```typescript
+await redis.set('key', 'value', 60); // 60秒后过期
+await redis.set('key', 'value');     // 永不过期
+```
+
+### get(key)
+获取值，不存在或已过期返回null
+```typescript
+const value = await redis.get('key');
+```
+
+### del(key)
+删除键，返回是否删除成功
+```typescript
+const deleted = await redis.del('key');
+```
+
+### exists(key)
+检查键是否存在
+```typescript
+const exists = await redis.exists('key');
+```
+
+### expire(key, ttl)
+设置键的过期时间
+```typescript
+await redis.expire('key', 300); // 5分钟后过期
+```
+
+### ttl(key)
+获取键的剩余过期时间
+```typescript
+const remaining = await redis.ttl('key');
+// -1: 永不过期
+// -2: 键不存在
+// >0: 剩余秒数
+```
+
+### flushall()
+清空所有数据
+```typescript
+await redis.flushall();
+```
+
+## 文件存储详情
+
+### 数据存储位置
+- 数据目录: `./redis-data/`
+- 数据文件: `./redis-data/redis.json`
+
+### 过期清理
+- 自动清理: 每分钟检查并清理过期键
+- 访问时清理: 获取数据时自动检查过期状态
+- 持久化: 数据变更时自动保存到文件
+
+### 数据格式
+```json
+{
+  "key1": {
+    "value": "data",
+    "expireAt": 1640995200000
+  },
+  "key2": {
+    "value": "permanent_data"
+  }
+}
+```
+
+## 切换模式
+
+### 自动切换规则
+1. `NODE_ENV=development` 且 `USE_FILE_REDIS=true` → 文件存储
+2. `USE_FILE_REDIS=false` → 真实Redis
+3. 生产环境默认使用真实Redis
+
+### 手动切换
+修改环境变量后重启应用即可切换模式：
+```bash
+# 切换到文件模式
+USE_FILE_REDIS=true
+
+# 切换到Redis模式  
+USE_FILE_REDIS=false
+```
+
+## 测试
+
+运行Redis适配器测试：
+```bash
+npm run build
+node test-redis-adapter.js
+```
+
+## 注意事项
+
+1. **数据迁移**: 文件存储和Redis之间的数据不会自动同步
+2. **性能**: 文件存储适合开发测试，生产环境建议使用Redis
+3. **并发**: 文件存储不支持高并发，仅适用于单进程开发环境
+4. **备份**: 生产环境请确保Redis数据的备份和高可用配置
+
+## 故障排除
+
+### 文件权限错误
+确保应用有权限在项目目录创建 `redis-data` 文件夹
+
+### Redis连接失败
+检查Redis服务器配置和网络连接：
+```bash
+# 测试Redis连接
+redis-cli -h your_host -p 6379 ping
+```
+
+### 模块导入错误
+确保在使用Redis服务的模块中正确导入了RedisModule
