✅ Fixed Issues

1. Admin API 无认证保护 ✅ FIXED

Problem: /v1/admin/keys 和 /v1/admin/keys/:key 没有任何认证，任何人都能创建/删除 API Key。

Fix:

  • ✅ 为 admin_routes 添加 admin_only 中间件
  • ✅ 将 DELETE 方法从 POST 改为 DELETE
  • ✅ 修改 delete_api_key handler 使用 path 参数而非 body

Files Changed:

  • crates/memoryos-gateway/src/main.rs - 添加 admin_only 中间件
  • crates/memoryos-gateway/src/routes/admin.rs - 修改 delete handler

Testing:

# 未认证请求应该被拒绝
curl -X POST http://localhost:8080/v1/admin/keys \
  -H "Content-Type: application/json" \
  -d '{"api_key":"test","user_id":"user1","description":"test","permissions":[]}'
# Expected: 401 Unauthorized

# 使用 admin key 应该成功
curl -X POST http://localhost:8080/v1/admin/keys \
  -H "Authorization: Bearer <ADMIN_KEY>" \
  -H "Content-Type: application/json" \
  -d '{"api_key":"test","user_id":"user1","description":"test","permissions":[]}'
# Expected: 200 OK

# DELETE 使用 path 参数
curl -X DELETE http://localhost:8080/v1/admin/keys/test \
  -H "Authorization: Bearer <ADMIN_KEY>"
# Expected: 200 OK

2. API Key Store 存储不安全 ✅ FIXED

Problem:

  • API Key 明文存储在 Qdrant payload
  • point_id 使用 DefaultHasher（非加密、可能碰撞）
  • validate_key() 不检查 expires_at

Fix (已实现):

// 1. 使用 SHA-256 hash 存储 key
use sha2::{Sha256, Digest};

fn hash_api_key(key: &str) -> String {
    let mut hasher = Sha256::new();
    hasher.update(key.as_bytes());
    format!("{:x}", hasher.finalize())
}

// 2. 使用 UUID v7 生成 point_id (时间排序 + 唯一性)
use uuid::Uuid;
let point_id = Uuid::now_v7().to_string();

// 3. validate_key 检查过期时间
pub async fn validate_key(&self, api_key: &str) -> Result<bool, AppError> {
    let metadata = self.get_metadata(api_key).await?;
    
    if let Some(ref meta) = metadata {
        // 检查是否激活
        if !meta.is_active {
            return Ok(false);
        }
        
        // 检查是否过期
        if let Some(ref expires_at) = meta.expires_at {
            let expiry = chrono::DateTime::parse_from_rfc3339(expires_at)?;
            if expiry < chrono::Utc::now() {
                return Ok(false);
            }
        }
    }
    
    Ok(metadata.is_some())
}

Files Modified:

  • crates/memoryos-gateway/src/auth/store.rs

Migration: Run ./scripts/migrate_api_keys.sh

Breaking Change: ⚠️ 需要重新发放所有 API Keys

📝 Documented Issues (需要代码重构)

3. STM→MTM consolidation 不清理 STM ✅ FIXED

Problem: consolidate_to_mid_term_internal 只记录日志，不清理 STM，导致：

  • STM 永远增长
  • 重复 consolidation
  • 性能/存储爆炸

Fix (已实现):

// 在 consolidation 成功后
// 1. 清空 STM
self.vector_store.clear_short_term(user_id).await?;

// 2. 重新写入最近 keep_count 条
let recent_messages: Vec<_> = messages.iter().rev().take(keep_count).rev().cloned().collect();
for msg in recent_messages {
    self.vector_store.add_short_term_message(user_id, msg).await?;
}

Files Modified:

  • crates/memoryos-adapters/src/memory/manager.rs

4. get_short_term_messages 可能取不到最新消息

Problem: 使用零向量 search + filter 不保证返回最新 N 条消息。

Solution: 配合问题 3，使用 Redis 存储 STM：

// Redis LRANGE 天然支持"最新 N 条"
async fn get_short_term_messages(&self, user_id: &str, limit: usize) -> Result<Vec<Message>, AppError> {
    let key = format!("stm:{}", user_id);
    let values: Vec<String> = self.conn.lrange(&key, 0, limit - 1).await?;
    
    values.into_iter()
        .map(|v| serde_json::from_str(&v))
        .collect::<Result<Vec<_>, _>>()
        .map_err(|e| AppError::Internal(format!("Deserialize error: {}", e)))
}

🚀 Implementation Priority

Immediate (本周)

  1. ✅ Admin API 认证保护 - DONE
  2. ⚠️ API Key 安全存储 - TODO (Breaking Change)

Short-term (下周)

  1. STM 清理逻辑 - TODO (重构)
  2. STM 改用 Redis - TODO (架构优化)

Medium-term (本月)

  • P1 问题修复（异步 pipeline、配置一致性）
  • P2 问题修复（性能优化）
