|
||||
## 4. gRPC 内部通信验证
|
||||
|
||||
### 4.1 协议说明
|
||||
|
||||
gRPC 用于微服务间的高性能内部通信：
|
||||
- 二进制协议 (Protocol Buffers)
|
||||
- 强类型接口定义
|
||||
- 双向流支持
|
||||
- HTTP/2 多路复用
|
||||
- 仅在 Docker 内部网络可访问 (端口 50051 不暴露)
|
||||
|
||||
### 4.2 gRPC 服务架构
|
||||
|
||||
**gRPC Server (提供服务)**:
|
||||
- `session-coordinator:50051` - 会话协调服务
|
||||
- `message-router:50051` - 消息路由服务
|
||||
- `account-service:50051` - 账户服务 (如需要)
|
||||
|
||||
**gRPC Client (调用服务)**:
|
||||
- `account-service` → 调用 `session-coordinator`
|
||||
- `server-party-1/2/3` → 调用 `session-coordinator`, `message-router`
|
||||
- `server-party-api` → 调用 server-party services
|
||||
|
||||
### 4.3 端口监听验证
|
||||
|
||||
通过 Docker 容器内部检查服务监听端口：
|
||||
|
||||
```bash
|
||||
# 在 session-coordinator 容器内查看监听端口
|
||||
docker compose exec session-coordinator netstat -tlnp
|
||||
```
|
||||
|
||||
**结果**:
|
||||
```
|
||||
Proto Local Address State PID/Program name
|
||||
tcp :::8080 LISTEN 1/session-coordinator
|
||||
tcp :::50051 LISTEN 1/session-coordinator
|
||||
```
|
||||
|
||||
✅ **验证通过**: session-coordinator 同时监听 HTTP (8080) 和 gRPC (50051)
|
||||
|
||||
类似地验证其他服务：
|
||||
- ✅ message-router: 监听 8080 (HTTP) + 50051 (gRPC)
|
||||
- ✅ account-service: 监听 8080 (HTTP) + 50051 (gRPC)
|
||||
|
||||
### 4.4 内部网络连通性测试
|
||||
|
||||
测试 Docker 内部网络中 gRPC 端口的可达性：
|
||||
|
||||
```bash
|
||||
# 从 account-service 测试到 session-coordinator
|
||||
docker compose exec account-service nc -zv mpc-session-coordinator 50051
|
||||
```
|
||||
|
||||
**结果**:
|
||||
```
|
||||
mpc-session-coordinator (172.18.0.5:50051) open
|
||||
```
|
||||
|
||||
✅ **gRPC 端口可达**
|
||||
|
||||
**完整连通性测试结果**:
|
||||
|
||||
| 源服务 | 目标服务 | 端口 | 结果 |
|
||||
|-------|---------|------|------|
|
||||
| account-service | session-coordinator | 50051 | ✅ OPEN |
|
||||
| account-service | message-router | 50051 | ✅ OPEN |
|
||||
| session-coordinator | message-router | 50051 | ✅ OPEN |
|
||||
| message-router | server-party-1 | 50051 | ✅ 可达 |
|
||||
| message-router | server-party-2 | 50051 | ✅ 可达 |
|
||||
| message-router | server-party-3 | 50051 | ✅ 可达 |
|
||||
|
||||
✅ **所有关键 gRPC 服务间通信正常**
|
||||
|
||||
### 4.5 端口隔离验证
|
||||
|
||||
验证 gRPC 端口不暴露到宿主机：
|
||||
|
||||
```bash
|
||||
# 从宿主机尝试连接 gRPC 端口 (应该失败)
|
||||
grpcurl -plaintext localhost:50051 list
|
||||
```
|
||||
|
||||
**结果**:
|
||||
```
|
||||
Failed to dial target host "localhost:50051": connection refused
|
||||
```
|
||||
|
||||
✅ **验证通过**: gRPC 端口正确隔离，仅内部网络可访问
|
||||
|
||||
**安全设计**:
|
||||
- ✅ HTTP (8080) → 映射到宿主机 (外部访问)
|
||||
- ✅ gRPC (50051) → 仅 Docker 内部网络 (安全隔离)
|
||||
|
||||

|
||||
|
||||
## 5. 2-of-3 签名流程验证
|
||||
|
||||
### 5.1 流程说明
|
||||
|
||||
MPC 系统实现的 2-of-3 阈值签名方案：
|
||||
|
||||
- **N = 3**: 总共 3 个服务器方 (server-party-1, 2, 3)
|
||||
- **T = 2**: 至少需要 2 个服务器方参与签名
|
||||
- **特性**: 任意 2 个服务器方可以完成签名，提供容错能力
|
||||
|
||||
### 5.2 完整签名流程

### 5.3 已验证步骤
|
||||
|
||||
#### ✅ Step 1: 创建 Keygen 会话
|
||||
```bash
|
||||
POST /api/v1/mpc/keygen
|
||||
{
|
||||
"threshold_n": 3,
|
||||
"threshold_t": 2,
|
||||
"participants": [
|
||||
{"party_id": "server-party-1"},
|
||||
{"party_id": "server-party-2"},
|
||||
{"party_id": "server-party-3"}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**结果**: 会话创建成功，返回 session_id 和 join_tokens
|
||||
|
||||
#### ✅ Step 2: 查询会话状态
|
||||
```bash
|
||||
GET /api/v1/mpc/sessions/{session_id}
|
||||
```
|
||||
|
||||
**结果**: 正确追踪 3 个参与方，等待加入
|
||||
|
||||
#### ✅ Step 3: 签名会话验证
|
||||
```bash
|
||||
POST /api/v1/mpc/sign
|
||||
{
|
||||
"account_id": "valid_account_id",
|
||||
"message_hash": "0x...",
|
||||
"participants": [
|
||||
{"party_id": "server-party-1"},
|
||||
{"party_id": "server-party-2"}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**结果**: API 端点就绪，正确验证账户存在
|
||||
|
||||
### 5.4 待完成步骤
|
||||
|
||||
为完成端到端 2-of-3 签名验证，还需要：
|
||||
|
||||
1. ⏳ **服务器方加入会话**
|
||||
- 3 个 server-party 使用 join_tokens 加入 keygen 会话
|
||||
- 执行 MPC keygen 协议生成分布式密钥
|
||||
|
||||
2. ⏳ **创建账户**
|
||||
- 使用 keygen 结果创建账户
|
||||
- 存储加密的密钥分片 (AES-256-GCM)
|
||||
|
||||
3. ⏳ **执行 2-of-3 签名**
|
||||
- 任选 2 个服务器方参与签名
|
||||
- 执行 MPC 签名协议生成签名
|
||||
|
||||
4. ⏳ **验证签名**
|
||||
- 验证生成的签名有效性
|

|
||||
|
||||
## 6. 架构验证
|
||||
|
||||
### 6.1 双协议架构
|
||||
|
||||
MPC 系统正确实现了双协议架构：
|
||||
|
||||
| 协议 | 用途 | 端口 | 暴露范围 | 状态 |
|
||||
|-----|------|------|---------|------|
|
||||
| HTTP REST | 外部 API | 4000, 8081-8083 | 宿主机 | ✅ 已验证 |
|
||||
| gRPC | 内部通信 | 50051 | Docker 内部 | ✅ 已验证 |
|
||||
|
||||
### 6.2 服务发现
|
||||
|
||||
服务通过 Docker Compose 网络自动发现：
|
||||
|
||||
```yaml
|
||||
# 服务可以通过服务名访问
|
||||
mpc-session-coordinator:50051
|
||||
mpc-message-router:50051
|
||||
mpc-account-service:4000
|
||||
```
|
||||
|
||||
✅ **服务发现正常工作**
|
||||
|
||||
### 6.3 连接重试机制
|
||||
|
||||
所有服务实现了指数退避重试逻辑：
|
||||
|
||||
```go
|
||||
const maxRetries = 10
|
||||
const retryDelay = 2 * time.Second
|
||||
|
||||
for i := 0; i < maxRetries; i++ {
|
||||
// 尝试连接
|
||||
if success {
|
||||
return connection
|
||||
}
|
||||
// 指数退避
|
||||
time.Sleep(retryDelay * time.Duration(i+1))
|
||||
}
|
||||
```
|
||||
|
||||
**重试配置**:
|
||||
- PostgreSQL: 10 次重试，关键服务
|
||||
- RabbitMQ: 10 次重试，关键服务
|
||||
- Redis: 10 次重试，非关键 (失败后继续)
|
||||
|
||||
✅ **所有服务连接重试已实现** (见 [session-coordinator/cmd/server/main.go:170-262](../services/session-coordinator/cmd/server/main.go#L170-L262))

test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
|
||||
interval: 10s
|
||||
timeout: 5s
|
||||
retries: 3
|
||||
start_period: 30s
|
||||
```
|
||||
|
||||
✅ **所有 10 个服务健康检查通过**
|
||||

## 7. 集成指南
|
||||
|
||||
### 7.1 从后端服务调用 MPC 系统
|
||||
|
||||
#### 7.1.1 配置
|
||||
|
||||
在后端服务 (如 `mpc-service`) 中配置：
|
||||
|
||||
```env
|
||||
# MPC System Configuration
|
||||
MPC_API_KEY=change_this_api_key_to_match_your_mpc_service_config
|
||||
MPC_BASE_URL=http://mpc-account-service:4000
|
||||
```
|
||||
|
||||
#### 7.1.2 创建钱包 (Keygen)
|
||||
|
||||
```javascript
|
||||
// Node.js 示例
|
||||
const axios = require('axios');
|
||||
|
||||
async function createWallet(userId) {
|
||||
const response = await axios.post(
|
||||
`${process.env.MPC_BASE_URL}/api/v1/mpc/keygen`,
|
||||
{
|
||||
threshold_n: 3,
|
||||
threshold_t: 2,
|
||||
participants: [
|
||||
{ party_id: 'server-party-1', device_type: 'server', device_id: 'party1' },
|
||||
{ party_id: 'server-party-2', device_type: 'server', device_id: 'party2' },
|
||||
{ party_id: 'server-party-3', device_type: 'server', device_id: 'party3' }
|
||||
]
|
||||
},
|
||||
{
|
||||
headers: {
|
||||
'X-API-Key': process.env.MPC_API_KEY,
|
||||
'Content-Type': 'application/json'
|
||||
}
|
||||
}
|
||||
);
|
||||
|
||||
return response.data.session_id;
|
||||
}
|
||||
```
|
||||
|
||||
#### 7.1.3 查询会话状态
|
||||
|
||||
```javascript
|
||||
async function getSessionStatus(sessionId) {
|
||||
const response = await axios.get(
|
||||
`${process.env.MPC_BASE_URL}/api/v1/mpc/sessions/${sessionId}`,
|
||||
{
|
||||
headers: {
|
||||
'X-API-Key': process.env.MPC_API_KEY
|
||||
}
|
||||
}
|
||||
);
|
||||
|
||||
return response.data;
|
||||
}
|
||||
```
|
||||
|
||||
#### 7.1.4 签名交易
|
||||
|
||||
```javascript
|
||||
async function signTransaction(accountId, messageHash) {
|
||||
const response = await axios.post(
|
||||
`${process.env.MPC_BASE_URL}/api/v1/mpc/sign`,
|
||||
{
|
||||
account_id: accountId,
|
||||
message_hash: messageHash,
|
||||
participants: [
|
||||
{ party_id: 'server-party-1' },
|
||||
{ party_id: 'server-party-2' }
|
||||
]
|
||||
},
|
||||
{
|
||||
headers: {
|
||||
'X-API-Key': process.env.MPC_API_KEY,
|
||||
'Content-Type': 'application/json'
|
||||
}
|
||||
}
|
||||
);
|
||||
|
||||
return response.data.signature;
|
||||
}
|
||||
```
|
||||
|
||||
### 7.2 错误处理
|
||||
|
||||
```javascript
|
||||
try {
|
||||
const sessionId = await createWallet(userId);
|
||||
} catch (error) {
|
||||
if (error.response) {
|
||||
// API 返回错误
|
||||
console.error('API Error:', error.response.data.error);
|
||||
} else if (error.request) {
|
||||
// 网络错误
|
||||
console.error('Network Error:', error.message);
|
||||
} else {
|
||||
// 其他错误
|
||||
console.error('Error:', error.message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 7.3 安全建议
|
||||
|
||||
1. **API 密钥管理**
|
||||
- 使用环境变量存储 API 密钥
|
||||
- 定期轮换密钥
|
||||
- 不要在代码中硬编码
|
||||
|
||||
2. **网络隔离**
|
||||
- MPC 系统应在私有网络中
|
||||
- 使用防火墙限制访问
|
||||
- 配置 IP 白名单
|
||||
|
||||
3. **HTTPS/TLS**
|
||||
- 生产环境使用 HTTPS
|
||||
- 配置有效的 SSL 证书
|
||||
- 启用证书验证
|
||||

|
||||
|
||||
## 8. 故障排查
|
||||
|
||||
### 8.1 服务健康检查失败
|
||||
|
||||
**症状**: `docker compose ps` 显示服务 unhealthy
|
||||
|
||||
**排查步骤**:
|
||||
```bash
|
||||
# 查看服务日志
|
||||
docker compose logs session-coordinator
|
||||
|
||||
# 检查健康检查端点
|
||||
curl http://localhost:8081/health
|
||||
|
||||
# 检查容器内部
|
||||
docker compose exec session-coordinator /bin/sh
|
||||
```
|
||||
|
||||
### 8.2 gRPC 连接失败
|
||||
|
||||
**症状**: 日志显示 "Failed to connect to RabbitMQ" 或 "dial tcp: connection refused"
|
||||
|
||||
**排查步骤**:
|
||||
```bash
|
||||
# 检查目标服务是否运行
|
||||
docker compose ps
|
||||
|
||||
# 测试网络连通性
|
||||
docker compose exec account-service nc -zv mpc-session-coordinator 50051
|
||||
|
||||
# 检查服务日志
|
||||
docker compose logs message-router
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
- 服务启动顺序问题 → 重启服务: `docker compose restart account-service`
|
||||
- 连接重试机制会自动处理临时连接失败
|
||||
|
||||
### 8.3 HTTP API 返回 401 Unauthorized
|
||||
|
||||
**症状**: API 调用返回 `{"error": "unauthorized"}`
|
||||
|
||||
**排查步骤**:
|
||||
```bash
|
||||
# 检查 API 密钥配置
|
||||
grep MPC_API_KEY backend/mpc-system/.env
|
||||
|
||||
# 验证请求头
|
||||
curl -v -H "X-API-Key: xxx" http://localhost:4000/health
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
- 确保 `X-API-Key` 请求头正确
|
||||
- 确保 API 密钥与 `.env` 配置一致
|
||||
|
||||
### 8.4 HTTP API 返回 403 Forbidden
|
||||
|
||||
**症状**: API 调用返回 403 错误
|
||||
|
||||
**原因**: IP 白名单配置
|
||||
|
||||
**排查步骤**:
|
||||
```bash
|
||||
# 检查 IP 白名单
|
||||
grep ALLOWED_IPS backend/mpc-system/.env
|
||||
|
||||
# 检查客户端 IP
|
||||
curl ifconfig.me
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
- 更新 `.env` 中的 `ALLOWED_IPS`
|
||||
- 重启服务: `docker compose restart`
|
||||
|
||||
### 8.5 会话卡在 "waiting" 状态
|
||||
|
||||
**症状**: 会话创建后一直处于 "waiting" 状态
|
||||
|
||||
**可能原因**:
|
||||
- 服务器方未加入会话
|
||||
- 消息路由服务问题
|
||||
|
||||
**排查步骤**:
|
||||
```bash
|
||||
# 检查 message-router 日志
|
||||
docker compose logs message-router
|
||||
|
||||
# 检查 server-party 日志
|
||||
docker compose logs server-party-1
|
||||
docker compose logs server-party-2
|
||||
docker compose logs server-party-3
|
||||
|
||||
# 查看会话详细状态
|
||||
curl http://localhost:4000/api/v1/mpc/sessions/{session_id} \
|
||||
-H "X-API-Key: xxx"
|
||||
```
