callback_url
string<uri>

任务完成后的HTTPS回调地址

回调时机:

  • 任务完成(completed)、失败(failed)或取消(cancelled)时触发
  • 在计费确认完成后发送

安全限制:

  • 仅支持HTTPS协议
  • 禁止回调到内网IP地址(127.0.0.1、10.x.x.x、172.16-31.x.x、192.168.x.x等)

回调机制:

  • 超时时间:10
  • 失败后最多重试3次(会分别在失败的1秒/2秒/4秒后进行重试)
  • 回调响应体格式与任务查询接口返回的格式一致
  • 回调地址若返回2xx状态码视为成功,其他状态码会触发重试
