请求去重 + 实时推送

两项关键的工程优化

  • 策略:hash(prompt + assetType + params) 生成唯一键
  • 存储:sync.Map 内存缓存,TTL 自动过期
  • 逻辑:相同参数的并发请求自动合并,返回已有 taskId
  • 效果:避免重复生成,节省 API 调用成本,提升用户体验
  • 用户建立 ws://host/api/v1/tasks/:taskId/ws 连接
  • 管线各阶段执行时推送实时状态消息:
{
  "type": "progress",
  "stage": "asset_generator",
  "progress": 45,
  "message": "正在生成素材..."
}
  • 质检重试时推送额外信息:重试次数、重试原因
  • 管线完成时推送最终结果:素材 URL、元数据
  • 兼容方案:同时支持 HTTP 轮询(GET /api/v1/tasks/:taskId)
