功能说明
数据万象支持自定义设置回调 URL，在任务完成后，系统向该 URL 发送 HTTP POST 请求，请求体中包含通知内容。您可通过配置的回调地址及时了解任务处理的进展和状态，以便进行其他业务操作。
回调内容
任务完成后，系统会向您设置的回调地址发送回调内容，包含完整节点数据的内容展示如下：

具体的数据内容如下：
节点名称（关键字） | 父节点 | 描述 | 类型 |
Response | 无 | 保存结果的容器 | Container |
Container 节点 Response 的内容：
节点名称（关键字） | 父节点 | 描述 | 类型 |
EventName | Response | 固定值，为 TaskFinish | String |
JobsDetail | Response | Container 数组 |
如果任务是通过工作流触发的，Response.JobsDetail.Input 还会包含 CosHeaders 节点，类型为 Container 数组。
Container 节点 CosHeaders 的内容：
节点名称（关键字） | 父节点 | 描述 | 类型 |
Key | Response.JobsDetail.Input.CosHeaders | 自定义 Header 的名称 | String |
Value | Response.JobsDetail.Input.CosHeaders | 自定义 Header 的值 | String |
如果任务是通过工作流触发的，Response.JobsDetail 还会包含 Workflow 节点，类型为 Container。
Container 节点 Workflow 的内容：
节点名称（关键字） | 父节点 | 描述 | 类型 |
RunId | Response.Workflow | 工作流实例 ID | String |
WorkflowId | Response.Workflow | 工作流 ID | String |
WorkflowName | Response.Workflow | 工作流名称 | String |
Name | Response.Workflow | 工作流节点名称 | String |
