# 流程节点状态变更

流程中节点状态发生变化会触发该事件。配置的节点为节点定义（node_definition_id 是唯一标识）。在流程实例中，每个流程实例生成的节点实例会不同（此功能不受数据权限范围控制）。

**注意事项**：你需要在应用内配置事件订阅，并订阅该事件，这样才可以在事件触发时接收到事件数据。了解事件订阅可参见[事件概述](https://open.feishu.cn/document/ukTMukTMukTM/uUTNz4SN1MjL1UzM)。

## 事件

## 示例场景

一个流程需要依次经过「审批1」 -> 「审批2」这2个审批节点。

假设:

「审批1」的node_definition_id="approval_1"

「审批2」的node_definition_id="approval_2"

- 当流程发起后，并且「审批1」节点状态变成“进行中”，发送如下事件，其中"node_definition_id":"approval_1"，"node_status":1，表示「审批1」节点状态变为进行中

```json
 {"event":{"flow_definition_id":"people_7023711013443944467_7382148112896872236","node_definition_id":"approval_1","process_id":"7384728360900888108","process_node_id":"7384728405024982572","node_type":1,"node_status":1,"biz_type":"corehr_probation_default_flow"},"header":{"event_id":"e4b6da0748b238261c4eedb809666898","event_time":"1719391068392","tenant_id":"7024043141149753363"}}
```

- 当审批人完成对「审批1」节点的审批，节点状态变成“已完成”，发送如下2个事件；

- "node_definition_id":"approval_1"，"node_status":3，表示「审批1」节点已完成

```json
{"event":{"flow_definition_id":"people_7023711013443944467_7382148112896872236","node_definition_id":"approval_1","process_id":"7384728360900888108","process_node_id":"7384728405024982572","node_type":1,"node_status":3,"biz_type":"corehr_probation_default_flow"},"header":{"event_id":"c0ba07d36568182261cfb9dbab1260eb","event_time":"1719391089652","tenant_id":"7024043141149753363"}}
```

- node_definition_id="approval_2"，node_status=1的事件，表示「审批2」节点变为进行中

```json
{"event":{"flow_definition_id":"people_7023711013443944467_7382148112896872236","node_definition_id":"approval_2","process_id":"7384728360900888108","process_node_id":"7384728494439155244","node_type":1,"node_status":1,"biz_type":"corehr_probation_default_flow"},"header":{"event_id":"f6206e0e152423585833295bc444fada","event_time":"1719391090119","tenant_id":"7024043141149753363"}}
```
