Camunda Rest -已完成流程实例的获取变量
Camunda Rest -已完成流程实例的获取变量
提问于 2022-02-08 18:51:57
我试图建立一个审计跟踪和打印信息的用户路径到任务完成+一些数据是用变量编写的。
camunda中有一些历史端点可以提供任务通过的每个“节点”。
但是，在流程实例变量中有一些我需要的额外信息，但是当我试图从已经完成的流程实例中获取变量时，API会回答为“没有id:xxxx找到的流程实例”。
是否有办法读取已完成任务的变量中的信息？
提前谢谢你

流程实例完成后，其数据将从运行时表中删除，运行时表将由用于运行实例的端点访问。所有有关已完成流程实例的信息都需要使用历史端点获取(底层API访问历史表)。https://docs.camunda.org/manual/7.16/reference/rest/history/
使用查询参数processInstanceId的端点将返回已完成实例的数据：https://docs.camunda.org/manual/7.16/reference/rest/history/variable-instance/get-variable-instance-query/
示例请求：
curl -X GET "http://localhost:8080/engine-rest/history/variable-instance?processInstanceId=5487fe88-72d2-11ec-b607-0242ac110002" -H "accept: application/json"答复示例：
