# MPC Party Service API 文档
|
||||
|
||||
## 概述
|
||||
|
||||
MPC Party Service 提供 RESTful API,用于参与 MPC 密钥生成、签名和密钥轮换操作。
|
||||
|
||||
**基础 URL**: `/api/v1/mpc-party`
|
||||
|
||||
**认证方式**: Bearer Token (JWT)
|
||||
|
||||
## 认证
|
||||
|
||||
除了健康检查端点外,所有 API 都需要 JWT 认证:
|
||||
|
||||
```http
|
||||
Authorization: Bearer <token>
|
||||
```
|
||||
|
||||
JWT Payload 结构:
|
||||
```json
|
||||
{
|
||||
"sub": "user-id",
|
||||
"type": "access",
|
||||
"partyId": "user123-server",
|
||||
"iat": 1699887766,
|
||||
"exp": 1699895766
|
||||
}
|
||||
```
|
||||
|
||||
## API 端点
|
||||
|
||||
### 健康检查
|
||||
|
||||
#### GET /health
|
||||
|
||||
检查服务健康状态。此端点不需要认证。
|
||||
|
||||
**请求**:
|
||||
```http
|
||||
GET /api/v1/mpc-party/health
|
||||
```
|
||||
|
||||
**响应** `200 OK`:
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": {
|
||||
"status": "ok",
|
||||
"service": "mpc-party-service",
|
||||
"timestamp": "2024-01-15T10:30:00.000Z"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 密钥生成 (Keygen)
|
||||
|
||||
#### POST /keygen/participate
|
||||
|
||||
参与 MPC 密钥生成会话(异步)。立即返回 202,后台异步执行 MPC 协议。
|
||||
|
||||
**请求**:
|
||||
```http
|
||||
POST /api/v1/mpc-party/keygen/participate
|
||||
Content-Type: application/json
|
||||
Authorization: Bearer <token>
|
||||
```
|
||||
|
||||
**请求体**:

"partyId": "user123-server",
|
||||
"joinToken": "join-token-abc123",
|
||||
"shareType": "wallet",
|
||||
"userId": "user-id-123"
|
||||
}

```
|
||||
|
||||
| 字段 | 类型 | 必填 | 描述 |
|
||||
|------|------|------|------|
|
||||
| sessionId | string (UUID) | 是 | 会话唯一标识 |

## 数据模型
|
||||
|
||||
### ShareType 枚举
|
||||
|
||||
```typescript
|
||||
enum ShareType {
|
||||
WALLET = 'wallet', // 用户钱包密钥分片
|
||||
CUSTODY = 'custody' // 托管密钥分片
|
||||
}
|
||||
```
|
||||
|
||||
### ShareStatus 枚举
|
||||
|
||||
```typescript
|
||||
enum ShareStatus {
|
||||
ACTIVE = 'active', // 活跃状态
|
||||
ROTATED = 'rotated', // 已轮换(旧分片)
|
||||
REVOKED = 'revoked' // 已撤销
|
||||
}
|
||||
```
|
||||
|
||||
### Threshold 格式
|
||||
|
||||
门限以 `t-of-n` 格式表示:
|
||||
- `n`: 总分片数
|
||||
- `t`: 签名所需最小分片数
|
||||
|
||||
示例:`2-of-3` 表示 3 个分片中需要 2 个才能签名。

# MPC Party Service 架构文档
|
||||
|
||||
## 概述
|
||||
|
||||
MPC Party Service 是 RWA Durian 系统中的多方计算(Multi-Party Computation)服务端组件。该服务负责参与分布式密钥生成、签名和密钥轮换协议,安全地管理服务端的密钥分片。
|
||||
|
||||
## 架构设计原则
|
||||
|
||||
### 1. 六边形架构 (Hexagonal Architecture)
|
||||
|
||||
本服务采用六边形架构(又称端口与适配器架构),实现业务逻辑与外部依赖的解耦:

### 2. CQRS 模式 (Command Query Responsibility Segregation)
|
||||
|
||||
命令和查询分离,提高系统的可扩展性和可维护性:
|
||||
|
||||
- **Commands**: 改变系统状态的操作
|
||||
- `ParticipateInKeygenCommand`
|
||||
- `ParticipateInSigningCommand`
|
||||
- `RotateShareCommand`
|
||||
|
||||
- **Queries**: 只读操作
|
||||
- `GetShareInfoQuery`
|
||||
- `ListSharesQuery`
|
||||
|
||||
### 3. 领域驱动设计 (DDD)
|
||||
|
||||
- **聚合根 (Aggregate Root)**: `PartyShare`
|
||||
- **值对象 (Value Objects)**: `ShareId`, `PartyId`, `SessionId`, `Threshold`, `ShareData`, `PublicKey`, `Signature`, `MessageHash`
|
||||
- **领域事件 (Domain Events)**: 用于解耦和异步处理
|
||||
- **仓储接口 (Repository Interfaces)**: 定义在领域层,实现在基础设施层

## 核心组件详解
|
||||
|
||||
### 1. Domain Layer (领域层)
|
||||
|
||||
#### PartyShare 实体
|
||||
|
||||
```typescript
|
||||
// src/domain/entities/party-share.entity.ts
|
||||
export class PartyShare {
|
||||
private readonly _id: ShareId;
|
||||
private readonly _partyId: PartyId;
|
||||
private readonly _sessionId: SessionId;
|
||||
private readonly _shareType: PartyShareType;
|
||||
private readonly _shareData: ShareData;
|
||||
private readonly _publicKey: PublicKey;
|
||||
private readonly _threshold: Threshold;
|
||||
private _status: PartyShareStatus;
|
||||
private _lastUsedAt?: Date;
|
||||
private readonly _domainEvents: DomainEvent[] = [];
|
||||
|
||||
// 工厂方法 - 创建新分片
|
||||
static create(props: CreatePartyShareProps): PartyShare;
|
||||
|
||||
// 工厂方法 - 从持久化数据重建
|
||||
static reconstruct(props: ReconstructPartyShareProps): PartyShare;
|
||||
|
||||
// 业务方法
|
||||
markAsUsed(): void;
|
||||
rotate(newShareData: ShareData, newSessionId: SessionId): PartyShare;
|
||||
revoke(reason: string): void;
|
||||
}
|
||||
```
|
||||
|
||||
#### Value Objects (值对象)
|
||||
|
||||
值对象是不可变的,通过值来识别:
|
||||
|
||||
```typescript
|
||||
// ShareId - 分片唯一标识
|
||||
export class ShareId {
|
||||
static create(value: string): ShareId;
|
||||
static generate(): ShareId;
|
||||
get value(): string;
|
||||
equals(other: ShareId): boolean;
|
||||
}
|
||||
|
||||
// Threshold - 门限配置
|
||||
export class Threshold {
|
||||
static create(n: number, t: number): Threshold;
|
||||
get n(): number; // 总分片数
|
||||
get t(): number; // 签名门限
|
||||
canSign(availableParties: number): boolean;
|
||||
}
|
||||
|
||||
// ShareData - 加密的分片数据
|
||||
export class ShareData {
|
||||
static create(encryptedData: Buffer, iv: Buffer, authTag: Buffer): ShareData;
|
||||
toJSON(): ShareDataJson;
|
||||
static fromJSON(json: ShareDataJson): ShareData;
|
||||
}
|
||||
```
|
||||
|
||||
#### Domain Services (领域服务)
|
||||
|
||||
```typescript
|
||||
// 分片加密服务
|
||||
export class ShareEncryptionDomainService {
|
||||
encrypt(plaintext: Buffer, masterKey: Buffer): EncryptedData;
|
||||
decrypt(encryptedData: EncryptedData, masterKey: Buffer): Buffer;
|
||||
generateMasterKey(): Buffer;
|
||||
deriveKeyFromPassword(password: string, salt: Buffer): Promise<Buffer>;
|
||||
}
|
||||
|
||||
// TSS 协议服务接口
|
||||
export interface TssProtocolDomainService {
|
||||
runKeygen(params: KeygenParams): Promise<KeygenResult>;
|
||||
runSigning(params: SigningParams): Promise<SigningResult>;
|
||||
runRefresh(params: RefreshParams): Promise<RefreshResult>;
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Application Layer (应用层)
|
||||
|
||||
#### Command Handlers
|
||||
|
||||
```typescript
|
||||
// ParticipateInKeygenHandler
|
||||
@CommandHandler(ParticipateInKeygenCommand)
|
||||
export class ParticipateInKeygenHandler {
|
||||
async execute(command: ParticipateInKeygenCommand): Promise<KeygenResultDto> {
|
||||
// 1. 加入会话
|
||||
const sessionInfo = await this.coordinatorClient.joinSession(/*...*/);
|
||||
|
||||
// 2. 运行 TSS Keygen 协议
|
||||
const keygenResult = await this.tssProtocolService.runKeygen(/*...*/);
|
||||
|
||||
// 3. 加密并保存分片
|
||||
const encryptedShare = this.encryptionService.encrypt(/*...*/);
|
||||
const partyShare = PartyShare.create(/*...*/);
|
||||
await this.partyShareRepository.save(partyShare);
|
||||
|
||||
// 4. 发布领域事件
|
||||
await this.eventPublisher.publishAll(partyShare.domainEvents);
|
||||
|
||||
return result;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Application Service
|
||||
|
||||
应用服务协调命令和查询处理器:
|
||||
|
||||
```typescript
|
||||
@Injectable()
|
||||
export class MPCPartyApplicationService {
|
||||
async participateInKeygen(params: ParticipateKeygenParams): Promise<KeygenResultDto>;
|
||||
async participateInSigning(params: ParticipateSigningParams): Promise<SigningResultDto>;
|
||||
async rotateShare(params: RotateShareParams): Promise<RotateResultDto>;
|
||||
async getShareInfo(shareId: string): Promise<ShareInfoDto>;
|
||||
async listShares(params: ListSharesParams): Promise<ListSharesResultDto>;
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Infrastructure Layer (基础设施层)
|
||||
|
||||
#### Repository Implementation
|
||||
|
||||
```typescript
|
||||
@Injectable()
|
||||
export class PartyShareRepositoryImpl implements PartyShareRepository {
|
||||
constructor(
|
||||
private readonly prisma: PrismaService,
|
||||
private readonly mapper: PartyShareMapper,
|
||||
) {}
|
||||
|
||||
async save(share: PartyShare): Promise<void> {
|
||||
const entity = this.mapper.toPersistence(share);
|
||||
await this.prisma.partyShare.create({ data: entity });
|
||||
}
|
||||
|
||||
async findById(id: ShareId): Promise<PartyShare | null> {
|
||||
const entity = await this.prisma.partyShare.findUnique({
|
||||
where: { id: id.value },
|
||||
});
|
||||
return entity ? this.mapper.toDomain(entity) : null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### External Service Clients
|
||||
|
||||
```typescript
|
||||
// MPC Coordinator Client - 与协调器通信
|
||||
@Injectable()
|
||||
export class MPCCoordinatorClient {
|
||||
async joinSession(params: JoinSessionParams): Promise<SessionInfo>;
|
||||
async reportCompletion(sessionId: string, status: string): Promise<void>;
|
||||
}
|
||||
|
||||
// Message Router Client - P2P 消息传递
|
||||
@Injectable()
|
||||
export class MPCMessageRouterClient {
|
||||
async subscribeMessages(sessionId: string): Promise<AsyncIterator<Message>>;
|
||||
async sendMessage(message: Message): Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
### 4. API Layer (API 层)
|
||||
|
||||
#### Controller
|
||||
|
||||
```typescript
|
||||
@Controller('mpc-party')
|
||||
@UseGuards(JwtAuthGuard)
|
||||
export class MPCPartyController {
|
||||
// 异步端点 - 立即返回 202
|
||||
@Post('keygen/participate')
|
||||
@HttpCode(HttpStatus.ACCEPTED)
|
||||
async participateInKeygen(@Body() dto: ParticipateKeygenDto): Promise<KeygenAcceptedDto>;
|
||||
|
||||
// 同步端点 - 等待完成
|
||||
@Post('keygen/participate-sync')
|
||||
async participateInKeygenSync(@Body() dto: ParticipateKeygenDto): Promise<KeygenResultDto>;
|
||||
|
||||
// 查询端点
|
||||
@Get('shares')
|
||||
async listShares(@Query() query: ListSharesDto): Promise<ListSharesResponseDto>;
|
||||
|
||||
@Get('shares/:shareId')
|
||||
async getShareInfo(@Param('shareId') shareId: string): Promise<ShareInfoResponseDto>;
|
||||
|
||||
// 公开端点
|
||||
@Public()
|
||||
@Get('health')
|
||||
health(): HealthStatus;
|
||||
}
|
||||
```
|
||||
|
||||

||||
|
||||

```
|
||||
|
||||
## 安全设计
|
||||
|
||||
### 1. 分片加密
|
||||
|
||||
所有密钥分片在存储前使用 AES-256-GCM 加密:
|
||||
|
||||
```typescript
|
||||
// 加密流程
|
||||
const { encryptedData, iv, authTag } = encryptionService.encrypt(
|
||||
shareData,
|
||||
masterKey
|
||||
);
|
||||
|
||||
// 存储加密后的数据
|
||||
const shareData = ShareData.create(encryptedData, iv, authTag);
|
||||
```
|
||||
|
||||
### 2. 访问控制
|
||||
|
||||
- JWT Token 验证
|
||||
- Party ID 绑定
|
||||
- 操作审计日志
|
||||
|
||||
### 3. 安全通信
|
||||
|
||||
- TLS 加密传输
|
||||
- 消息签名验证
|
||||
- 会话令牌认证
|
||||
|
||||
## 扩展性设计
|
||||
|
||||
### 1. 水平扩展
|
||||
|
||||
- 无状态服务设计
|
||||
- Redis 分布式锁
|
||||
- Kafka 事件驱动
|
||||
|
||||
### 2. 多协议支持
|
||||
|
||||
通过领域服务接口抽象,支持不同的 TSS 实现:
|
||||
|
||||
```typescript
|
||||
// 接口定义
|
||||
export interface TssProtocolDomainService {
|
||||
runKeygen(params: KeygenParams): Promise<KeygenResult>;
|
||||
runSigning(params: SigningParams): Promise<SigningResult>;
|
||||
runRefresh(params: RefreshParams): Promise<RefreshResult>;
|
||||
}
|
||||
|
||||
// 可替换实现
|
||||
// - GG20 实现
|
||||
// - FROST 实现
|
||||
// - 其他 TSS 协议
|
||||
```
|
||||
|
||||
### 3. 插件化设计
|
||||
|
||||
基础设施层的实现可以轻松替换:
|
||||
|
||||
- 数据库:Prisma 支持多种数据库
|
||||
- 缓存:可替换为其他缓存方案
|
||||
- 消息队列:可替换为 RabbitMQ 等
|
||||
|
||||
## 配置管理
|
||||
|
||||
```typescript
|
||||
// src/config/index.ts
|
||||
export const configurations = [
|
||||
() => ({
|
||||
port: parseInt(process.env.APP_PORT, 10) || 3006,
|
||||
env: process.env.NODE_ENV || 'development',
|
||||
apiPrefix: process.env.API_PREFIX || 'api/v1',
|
||||
|
||||
database: {
|
||||
url: process.env.DATABASE_URL,
|
||||
},
|
||||
|
||||
redis: {
|
||||
host: process.env.REDIS_HOST,
|
||||
port: parseInt(process.env.REDIS_PORT, 10) || 6379,
|
||||
},
|
||||
|
||||
mpc: {
|
||||
coordinatorUrl: process.env.MPC_COORDINATOR_URL,
|
||||
messageRouterWsUrl: process.env.MPC_MESSAGE_ROUTER_WS_URL,
|
||||
partyId: process.env.MPC_PARTY_ID,
|
||||
},
|
||||
|
||||
security: {
|
||||
jwtSecret: process.env.JWT_SECRET,
|
||||
shareMasterKey: process.env.SHARE_MASTER_KEY,
|
||||
},
|
||||
}),
|
||||
];
|
||||
```
|
||||
|
||||
## 监控与可观测性
|
||||
|
||||
### 1. 日志
|
||||
|
||||
使用 NestJS Logger,支持结构化日志:
|
||||
|
||||
```typescript
|
||||
private readonly logger = new Logger(MPCPartyController.name);
|
||||
|
||||
this.logger.log(`Keygen request: session=${sessionId}, party=${partyId}`);
|
||||
this.logger.error(`Keygen failed: ${error.message}`, error.stack);
|
||||
```
|
||||
|
||||
### 2. 健康检查
|
||||
|
||||
```typescript
|
||||
@Get('health')
|
||||
health() {
|
||||
return {
|
||||
status: 'ok',
|
||||
timestamp: new Date().toISOString(),
|
||||
service: 'mpc-party-service',
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 指标(待实现)
|
||||
|
||||
- 请求延迟
|
||||
- 错误率
|
||||
- MPC 协议执行时间
|
||||
- 分片操作统计
|
||||
|
||||

## 总结
|
||||
|
||||
MPC Party Service 采用清晰的分层架构,遵循 DDD 和 CQRS 原则,实现了:
|
||||
|
||||
1. **高内聚低耦合**:各层职责明确,依赖于抽象
|
||||
2. **可测试性**:依赖注入使得单元测试和集成测试易于实现
|
||||
3. **可扩展性**:插件化设计支持不同的 TSS 协议和基础设施
|
||||
4. **安全性**:多层安全措施保护敏感的密钥分片
|
||||
5. **可观测性**:完善的日志和健康检查支持运维监控

## 添加新功能指南
|
||||
|
||||
### 1. 添加新的 API 端点
|
||||
|
||||
#### Step 1: 创建 DTO
|
||||
|
||||
```typescript
|
||||
// src/api/dto/request/new-feature.dto.ts
|
||||
import { IsString, IsNotEmpty } from 'class-validator';
|
||||
import { ApiProperty } from '@nestjs/swagger';
|
||||
|
||||
export class NewFeatureDto {
|
||||
@ApiProperty({ description: 'Feature parameter' })
|
||||
@IsString()
|
||||
@IsNotEmpty()
|
||||
param: string;
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 2: 创建 Command/Query
|
||||
|
||||
```typescript
|
||||
// src/application/commands/new-feature/new-feature.command.ts
|
||||
export class NewFeatureCommand {
|
||||
constructor(
|
||||
public readonly param: string,
|
||||
) {}
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 3: 创建 Handler
|
||||
|
||||
```typescript
|
||||
// src/application/commands/new-feature/new-feature.handler.ts
|
||||
import { CommandHandler, ICommandHandler } from '@nestjs/cqrs';
|
||||
import { Injectable } from '@nestjs/common';
|
||||
import { NewFeatureCommand } from './new-feature.command';
|
||||
|
||||
@Injectable()
|
||||
@CommandHandler(NewFeatureCommand)
|
||||
export class NewFeatureHandler implements ICommandHandler<NewFeatureCommand> {
|
||||
async execute(command: NewFeatureCommand): Promise<any> {
|
||||
// 实现业务逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 4: 更新 Application Service
|
||||
|
||||
```typescript
|
||||
// src/application/services/mpc-party-application.service.ts
|
||||
async newFeature(params: NewFeatureParams): Promise<ResultDto> {
|
||||
const command = new NewFeatureCommand(params.param);
|
||||
return this.commandBus.execute(command);
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 5: 添加 Controller 端点
|
||||
|
||||
```typescript
|
||||
// src/api/controllers/mpc-party.controller.ts
|
||||
@Post('new-feature')
|
||||
@ApiOperation({ summary: '新功能' })
|
||||
@ApiResponse({ status: 200, description: 'Success' })
|
||||
async newFeature(@Body() dto: NewFeatureDto) {
|
||||
return this.mpcPartyService.newFeature(dto);
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 6: 编写测试
|
||||
|
||||
```typescript
|
||||
// tests/unit/application/new-feature.handler.spec.ts
|
||||
describe('NewFeatureHandler', () => {
|
||||
// ... 单元测试
|
||||
});
|
||||
|
||||
// tests/integration/new-feature.spec.ts
|
||||
describe('NewFeature (Integration)', () => {
|
||||
// ... 集成测试
|
||||
});
|
||||
```
|
||||
|
||||
### 2. 添加新的领域实体
|
||||
|
||||
#### Step 1: 定义实体
|
||||
|
||||
```typescript
|
||||
// src/domain/entities/new-entity.entity.ts
|
||||
import { DomainEvent } from '../events';
|
||||
|
||||
export class NewEntity {
|
||||
private readonly _id: EntityId;
|
||||
private readonly _domainEvents: DomainEvent[] = [];
|
||||
|
||||
private constructor(props: NewEntityProps) {
|
||||
this._id = props.id;
|
||||
}
|
||||
|
||||
static create(props: CreateNewEntityProps): NewEntity {
|
||||
const entity = new NewEntity({
|
||||
id: EntityId.generate(),
|
||||
...props,
|
||||
});
|
||||
|
||||
entity.addDomainEvent(new NewEntityCreatedEvent(entity.id.value));
|
||||
return entity;
|
||||
}
|
||||
|
||||
static reconstruct(props: NewEntityProps): NewEntity {
|
||||
return new NewEntity(props);
|
||||
}
|
||||
|
||||
// Getters
|
||||
get id(): EntityId {
|
||||
return this._id;
|
||||
}
|
||||
|
||||
get domainEvents(): DomainEvent[] {
|
||||
return [...this._domainEvents];
|
||||
}
|
||||
|
||||
// Business methods
|
||||
doSomething(): void {
|
||||
// 业务逻辑
|
||||
this.addDomainEvent(new SomethingDoneEvent(this._id.value));
|
||||
}
|
||||
|
||||
// Private methods
|
||||
private addDomainEvent(event: DomainEvent): void {
|
||||
this._domainEvents.push(event);
|
||||
}
|
||||
|
||||
clearDomainEvents(): void {
|
||||
this._domainEvents.length = 0;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 2: 定义值对象
|
||||
|
||||
```typescript
|
||||
// src/domain/value-objects/entity-id.ts
|
||||
export class EntityId {
|
||||
private constructor(private readonly _value: string) {}
|
||||
|
||||
static create(value: string): EntityId {
|
||||
if (!this.isValid(value)) {
|
||||
throw new DomainError('Invalid EntityId format');
|
||||
}
|
||||
return new EntityId(value);
|
||||
}
|
||||
|
||||
static generate(): EntityId {
|
||||
const timestamp = Date.now();
|
||||
const random = Math.random().toString(36).substring(2, 15);
|
||||
return new EntityId(`entity_${timestamp}_${random}`);
|
||||
}
|
||||
|
||||
private static isValid(value: string): boolean {
|
||||
return /^entity_\d+_[a-z0-9]+$/.test(value);
|
||||
}
|
||||
|
||||
get value(): string {
|
||||
return this._value;
|
||||
}
|
||||
|
||||
equals(other: EntityId): boolean {
|
||||
return this._value === other._value;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 3: 定义仓储接口
|
||||
|
||||
```typescript
|
||||
// src/domain/repositories/new-entity.repository.interface.ts
|
||||
import { NewEntity } from '../entities/new-entity.entity';
|
||||
import { EntityId } from '../value-objects';
|
||||
|
||||
export const NEW_ENTITY_REPOSITORY = Symbol('NEW_ENTITY_REPOSITORY');
|
||||
|
||||
export interface NewEntityRepository {
|
||||
save(entity: NewEntity): Promise<void>;
|
||||
findById(id: EntityId): Promise<NewEntity | null>;
|
||||
findMany(filters?: any): Promise<NewEntity[]>;
|
||||
delete(id: EntityId): Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 4: 实现仓储
|
||||
|
||||
```typescript
|
||||
// src/infrastructure/persistence/repositories/new-entity.repository.impl.ts
|
||||
@Injectable()
|
||||
export class NewEntityRepositoryImpl implements NewEntityRepository {
|
||||
constructor(
|
||||
private readonly prisma: PrismaService,
|
||||
private readonly mapper: NewEntityMapper,
|
||||
) {}
|
||||
|
||||
async save(entity: NewEntity): Promise<void> {
|
||||
const data = this.mapper.toPersistence(entity);
|
||||
await this.prisma.newEntity.create({ data });
|
||||
}
|
||||
|
||||
async findById(id: EntityId): Promise<NewEntity | null> {
|
||||
const record = await this.prisma.newEntity.findUnique({
|
||||
where: { id: id.value },
|
||||
});
|
||||
return record ? this.mapper.toDomain(record) : null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 添加新的外部服务集成
|
||||
|
||||
```typescript
|
||||
// src/infrastructure/external/new-service/new-service.client.ts
|
||||
import { Injectable, Logger } from '@nestjs/common';
|
||||
import { ConfigService } from '@nestjs/config';
|
||||
|
||||
@Injectable()
|
||||
export class NewServiceClient {
|
||||
private readonly logger = new Logger(NewServiceClient.name);
|
||||
private readonly baseUrl: string;
|
||||
|
||||
constructor(private readonly configService: ConfigService) {
|
||||
this.baseUrl = this.configService.get<string>('NEW_SERVICE_URL');
|
||||
}
|
||||
|
||||
async callExternalService(params: any): Promise<any> {
|
||||
this.logger.log(`Calling external service: ${JSON.stringify(params)}`);
|
||||
|
||||
try {
|
||||
// 实现外部服务调用
|
||||
const response = await fetch(`${this.baseUrl}/endpoint`, {
|
||||
method: 'POST',
|
||||
headers: { 'Content-Type': 'application/json' },
|
||||
body: JSON.stringify(params),
|
||||
});
|
||||
|
||||
if (!response.ok) {
|
||||
throw new Error(`External service error: ${response.status}`);
|
||||
}
|
||||
|
||||
return response.json();
|
||||
} catch (error) {
|
||||
this.logger.error(`External service failed: ${error.message}`, error.stack);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 调试技巧
|
||||
|
||||
### 1. VSCode 调试配置
|
||||
|
||||
`.vscode/launch.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": "0.2.0",
|
||||
"configurations": [
|
||||
{
|
||||
"type": "node",
|
||||
"request": "launch",
|
||||
"name": "Debug MPC Service",
|
||||
"runtimeArgs": [
|
||||
"-r",
|
||||
"ts-node/register",
|
||||
"-r",
|
||||
"tsconfig-paths/register"
|
||||
],
|
||||
"args": ["${workspaceFolder}/src/main.ts"],
|
||||
"cwd": "${workspaceFolder}",
|
||||
"env": {
|
||||
"NODE_ENV": "development"
|
||||
},
|
||||
"sourceMaps": true
|
||||
},
|
||||
{
|
||||
"type": "node",
|
||||
"request": "launch",
|
||||
"name": "Debug Tests",
|
||||
"program": "${workspaceFolder}/node_modules/.bin/jest",
|
||||
"args": [
|
||||
"--config",
|
||||
"${workspaceFolder}/tests/jest.config.js",
|
||||
"--runInBand",
|
||||
"--testPathPattern",
|
||||
"${file}"
|
||||
],
|
||||
"cwd": "${workspaceFolder}",
|
||||
"console": "integratedTerminal",
|
||||
"internalConsoleOptions": "neverOpen"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 日志调试
|
||||
|
||||
```typescript
|
||||
// 启用详细日志
|
||||
const app = await NestFactory.create(AppModule, {
|
||||
logger: ['error', 'warn', 'log', 'debug', 'verbose'],
|
||||
});
|
||||
|
||||
// 在代码中添加调试日志
|
||||
this.logger.debug(`Debug info: ${JSON.stringify(data)}`);
|
||||
this.logger.verbose(`Verbose details: ${details}`);
|
||||
```
|
||||
|
||||
### 3. 数据库调试
|
||||
|
||||
```bash
|
||||
# 查看 Prisma 生成的 SQL
|
||||
DEBUG=prisma:query npm run start:dev
|
||||
|
||||
# 使用 Prisma Studio 查看数据
|
||||
npx prisma studio
|
||||
```
|
||||
|
||||
### 4. API 调试
|
||||
|
||||
- 使用 Swagger UI: `http://localhost:3006/api/docs`
|
||||
- 使用 Postman 或 Insomnia
|
||||
- 查看请求/响应日志
|
||||
|
||||
---
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 1. 数据库优化
|
||||
|
||||
```typescript
|
||||
// 使用索引
|
||||
@@index([partyId, status])
|
||||
@@index([publicKey])
|
||||
|
||||
// 使用 select 限制字段
|
||||
const share = await this.prisma.partyShare.findUnique({
|
||||
where: { id },
|
||||
select: {
|
||||
id: true,
|
||||
status: true,
|
||||
publicKey: true,
|
||||
// 不选择大字段如 shareData
|
||||
},
|
||||
});
|
||||
|
||||
// 使用分页
|
||||
const shares = await this.prisma.partyShare.findMany({
|
||||
skip: (page - 1) * limit,
|
||||
take: limit,
|
||||
orderBy: { createdAt: 'desc' },
|
||||
});
|
||||
```
|
||||
|
||||
### 2. 缓存优化
|
||||
|
||||
```typescript
|
||||
// 使用 Redis 缓存
|
||||
@Injectable()
|
||||
export class CachedShareService {
|
||||
constructor(private readonly redis: Redis) {}
|
||||
|
||||
async getShareInfo(shareId: string): Promise<ShareInfo> {
|
||||
const cacheKey = `share:${shareId}`;
|
||||
|
||||
// 尝试从缓存获取
|
||||
const cached = await this.redis.get(cacheKey);
|
||||
if (cached) {
|
||||
return JSON.parse(cached);
|
||||
}
|
||||
|
||||
// 从数据库获取
|
||||
const share = await this.repository.findById(shareId);
|
||||
|
||||
// 存入缓存
|
||||
await this.redis.setex(cacheKey, 3600, JSON.stringify(share));
|
||||
|
||||
return share;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 异步处理
|
||||
|
||||
```typescript
|
||||
// 使用异步端点处理长时间操作
|
||||
@Post('keygen/participate')
|
||||
@HttpCode(HttpStatus.ACCEPTED)
|
||||
async participateInKeygen(@Body() dto: ParticipateKeygenDto) {
|
||||
// 立即返回,后台异步处理
|
||||
this.mpcPartyService.participateInKeygen(dto).catch(error => {
|
||||
this.logger.error(`Keygen failed: ${error.message}`);
|
||||
});
|
||||
|
||||
return {
|
||||
message: 'Keygen participation started',
|
||||
sessionId: dto.sessionId,
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 常见问题解决
|
||||
|
||||
### 1. Prisma 相关
|
||||
|
||||
**问题**: Prisma Client 未生成
|
||||
|
||||
```bash
|
||||
npx prisma generate
|
||||
```
|
||||
|
||||
**问题**: 数据库连接失败
|
||||
|
||||
检查 `DATABASE_URL` 环境变量格式:
|
||||
```
|
||||
mysql://user:password@host:port/database
|
||||
```
|
||||
|
||||
### 2. 测试相关
|
||||
|
||||
**问题**: 测试超时
|
||||
|
||||
```javascript
|
||||
// 增加超时时间
|
||||
jest.setTimeout(60000);
|
||||
```
|
||||
|
||||
**问题**: 模拟不生效
|
||||
|
||||
确保模拟在正确的位置:
|
||||
```typescript
|
||||
beforeEach(() => {
|
||||
jest.clearAllMocks();
|
||||
mockService.method.mockResolvedValue(expectedValue);
|
||||
});
|
||||
```
|
||||
|
||||
### 3. TypeScript 相关
|
||||
|
||||
**问题**: 路径别名不工作
|
||||
|
||||
检查 `tsconfig.json`:
|
||||
```json
|
||||
{
|
||||
"compilerOptions": {
|
||||
"paths": {
|
||||
"@/*": ["src/*"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**问题**: 类型错误
|
||||
|
||||
```bash
|
||||
# 重新生成类型
|
||||
npm run build
|
||||
npx prisma generate
|
||||
```
|
||||
|
||||
### 4. 运行时相关
|
||||
|
||||
**问题**: 端口已被占用
|
||||
|
||||
```bash
|
||||
# 查找占用端口的进程
|
||||
lsof -i :3006
|
||||
# 或在 Windows 上
|
||||
netstat -ano | findstr :3006
|
||||
|
||||
# 终止进程
|
||||
kill <PID>
|
||||
```
|
||||
|
||||
**问题**: 内存不足
|
||||
|
||||
```bash
|
||||
# 增加 Node.js 内存限制
|
||||
NODE_OPTIONS=--max-old-space-size=4096 npm run start:dev
|
||||
```
