## 2. 后端服务端口规划

| 服务名称 | 端口 | API 前缀 | 说明 |
|---------|------|----------|------|
| Identity Service | 3000 | `/api/v1` | 用户身份、认证、钱包创建 |
| MPC Service | 3001 | `/api/v1` | MPC 密钥分片管理 |
| Wallet Service | 3002 | `/api/v1` | 钱包余额、交易 |
| Planting Service | 3003 | `/api/v1` | 认种业务 |
| Referral Service | 3004 | `/api/v1` | 推荐关系、分享 |
| Reward Service | 3005 | `/api/v1` | 挖矿奖励、收益 |
| Authorization Service | 3006 | `/api/v1` | 权限管理 |
| Leaderboard Service | 3007 | `/api` | 排行榜 |
| Reporting Service | 3008 | `/api/v1` | 遥测统计、报表 |
| Backup Service | 3009 | - | MPC 备份 (内部服务) |

## 3. Nginx 配置

```nginx
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections 1024;
    use epoll;
    multi_accept on;
}

http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for" '
                    'rt=$request_time uct="$upstream_connect_time" '
                    'uht="$upstream_header_time" urt="$upstream_response_time"';

    access_log /var/log/nginx/access.log main;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    # Gzip 压缩
    gzip on;
    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 6;
    gzip_types text/plain text/css text/xml application/json application/javascript
               application/xml application/xml+rss text/javascript;

    # 限流配置
    limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;
    limit_conn_zone $binary_remote_addr zone=conn_limit:10m;

### 3.3 代理参数配置 `/etc/nginx/conf.d/proxy_params.conf`

```nginx
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header Connection "";

proxy_connect_timeout 60s;
proxy_send_timeout 60s;
proxy_read_timeout 60s;

proxy_buffering on;
proxy_buffer_size 4k;
proxy_buffers 8 4k;
proxy_busy_buffers_size 8k;
```

## 4. 前端配置修改

### 4.1 修改 API 端点配置

文件: `frontend/mobile-app/lib/core/constants/api_endpoints.dart`

```dart
class ApiEndpoints {
  ApiEndpoints._();

  // Base URL - 生产环境
  static const String baseUrl = 'https://rwaapi.szaiai.com';

  // Base URL - 开发环境 (可选)
  static const String baseUrlDev = 'https://rwaapi-dev.szaiai.com';

  // API 版本前缀
  static const String apiPrefix = '/api/v1';

  // Auth & User (-> Identity Service)
  static const String user = '$apiPrefix/user';
  static const String auth = '$apiPrefix/auth';
  static const String autoCreate = '$user/auto-create';
  static const String login = '$auth/login';
  static const String refreshToken = '$auth/refresh';
  static const String logout = '$auth/logout';
  static const String profile = '$user/profile';

  // Wallet (-> Wallet Service)
  static const String wallet = '$apiPrefix/wallet';
  static const String balance = '$wallet/balance';
  static const String createWallet = '$wallet/create';
  static const String importWallet = '$wallet/import';

  // Trading (-> Wallet Service)
  static const String trading = '$apiPrefix/trading';
  static const String exchange = '$trading/exchange';
  static const String settlement = '$trading/settlement';
  static const String transactions = '$trading/transactions';

  // Deposit (-> Wallet Service)
  static const String deposit = '$apiPrefix/deposit';
  static const String depositAddress = '$deposit/address';
  static const String confirmDeposit = '$deposit/confirm';

  // Mining & Reward (-> Reward Service)
  static const String mining = '$apiPrefix/mining';
  static const String miningStatus = '$mining/status';
  static const String startMining = '$mining/start';
  static const String stopMining = '$mining/stop';
  static const String claimReward = '$mining/claim';
  static const String hashPower = '$mining/hash-power';

  // Ranking (-> Leaderboard Service)
  static const String ranking = '$apiPrefix/ranking';
  static const String dailyRanking = '$ranking/daily';
  static const String weeklyRanking = '$ranking/weekly';
  static const String monthlyRanking = '$ranking/monthly';

  // Planting (-> Planting Service)
  static const String planting = '$apiPrefix/planting';
  static const String plantingPrice = '$planting/price';
  static const String submitPlanting = '$planting/submit';

  // Community & Referral (-> Referral Service)
  static const String community = '$apiPrefix/community';
  static const String referral = '$apiPrefix/referral';
  static const String referralList = '$community/referrals';
  static const String earnings = '$community/earnings';
  static const String generateReferralLink = '$referral/generate-link';

  // Telemetry (-> Reporting Service)
  static const String telemetry = '$apiPrefix/telemetry';
  static const String telemetrySession = '$telemetry/session';
  static const String telemetryHeartbeat = '$telemetry/heartbeat';
  static const String telemetryEvents = '$telemetry/events';
}
```

### 4.2 修改 API 客户端默认 URL

文件: `frontend/mobile-app/lib/core/network/api_client.dart`

```dart
// 修改默认 Base URL
static const String _defaultBaseUrl = 'https://rwaapi.szaiai.com';

// 开发模式可使用本地地址
// static const String _defaultBaseUrl = 'http://10.0.2.2:3000'; // Android 模拟器
// static const String _defaultBaseUrl = 'http://localhost:3000'; // iOS 模拟器
```

### 5.2 环境变量文件 `.env.prod`

```bash
# Database
DB_PASSWORD=your_secure_database_password

# JWT
JWT_SECRET=your_super_secure_jwt_secret_at_least_32_chars

# Redis
REDIS_PASSWORD=your_secure_redis_password

# Wallet Encryption
WALLET_ENCRYPTION_SALT=your_wallet_encryption_salt

# Service JWT (for inter-service communication)
SERVICE_JWT_SECRET=your_service_jwt_secret
```

## 6. 部署步骤

### 6.1 服务器准备

```bash
# 1. 安装 Docker 和 Docker Compose
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER

# 2. 创建部署目录
mkdir -p /opt/rwadurian
cd /opt/rwadurian

# 3. 克隆代码
git clone https://github.com/your-org/rwadurian.git .

# 4. 创建 Nginx 配置目录
mkdir -p nginx/{conf.d,ssl,logs}

# 5. 复制 Nginx 配置
cp docs/nginx/* nginx/

# 6. 安装 SSL 证书 (使用 Let's Encrypt 或购买的证书)
# 将证书放到 nginx/ssl/ 目录
```

### 6.2 启动服务

```bash
# 1. 复制并配置环境变量
cp .env.example .env.prod
vim .env.prod  # 修改为生产环境配置

# 2. 启动所有服务
docker compose -f docker-compose.prod.yml --env-file .env.prod up -d

# 3. 查看服务状态
docker compose -f docker-compose.prod.yml ps

# 4. 查看日志
docker compose -f docker-compose.prod.yml logs -f

# 5. 运行数据库迁移
docker compose -f docker-compose.prod.yml exec identity-service npx prisma migrate deploy
docker compose -f docker-compose.prod.yml exec wallet-service npx prisma migrate deploy
# ... 其他服务
```

### 6.3 验证部署

```bash
# 健康检查
curl https://rwaapi.szaiai.com/health

# 测试 API
curl https://rwaapi.szaiai.com/api/v1/user/auto-create \
  -H "Content-Type: application/json" \
  -d '{"deviceId": "test-device-123"}'
```

## 7. API 端点对照表

| 前端调用 | Nginx 路由 | 后端服务 | 服务端口 |
|---------|-----------|---------|---------|
| `/api/v1/user/*` | `/api/v1/user` | Identity Service | 3000 |
| `/api/v1/auth/*` | `/api/v1/auth` | Identity Service | 3000 |
| `/api/v1/wallet/*` | `/api/v1/wallet` | Wallet Service | 3002 |
| `/api/v1/trading/*` | `/api/v1/trading` | Wallet Service | 3002 |
| `/api/v1/deposit/*` | `/api/v1/deposit` | Wallet Service | 3002 |
| `/api/v1/mining/*` | `/api/v1/mining` | Reward Service | 3005 |
| `/api/v1/ranking/*` | `/api/v1/ranking` | Leaderboard Service | 3007 |
| `/api/v1/planting/*` | `/api/v1/planting` | Planting Service | 3003 |
| `/api/v1/referral/*` | `/api/v1/referral` | Referral Service | 3004 |
| `/api/v1/community/*` | `/api/v1/community` | Referral Service | 3004 |
| `/api/v1/telemetry/*` | `/api/v1/telemetry` | Reporting Service | 3008 |

## 8. 监控与日志

### 8.1 Nginx 日志

```bash
# 访问日志
tail -f /opt/rwadurian/nginx/logs/access.log

# 错误日志
tail -f /opt/rwadurian/nginx/logs/error.log
```

### 8.2 服务日志

```bash
# 查看特定服务日志
docker compose -f docker-compose.prod.yml logs -f identity-service

# 查看所有服务日志
docker compose -f docker-compose.prod.yml logs -f
```

## 9. 常见问题

### Q1: 502 Bad Gateway
- 检查后端服务是否正常运行
- 检查 Nginx upstream 配置的服务名是否正确
- 检查 Docker 网络是否正确连接

### Q2: CORS 错误
- 确认 Nginx 配置中 CORS 头已正确设置
- 确认 OPTIONS 预检请求处理正确

### Q3: SSL 证书问题
- 检查证书文件路径和权限
- 确认证书未过期
- 使用 `openssl s_client -connect rwaapi.szaiai.com:443` 测试
