elsa 使用 REST API 执行变更

变更模块公开了一个 REST API，以便直接执行变更。例如，要执行一个变更，该变更修改变量、将工作流实例迁移到新版本并安排活动，请使用以下请求：

POST /alterations/run HTTP/1.1
Host: localhost:5001

{
    "alterations": [
        {
            "type": "ModifyVariable",
            "variableId": "83fde420b5794bc39a0a7db725405511",
            "value": "Hello world!"
        },
        {
            "type": "Migrate",
            "targetVersion": 9
        },
        {
            "type": "ScheduleActivity",
            "activityId": "mY1rb4GRjkW3urm8dcNSog"
        }
    ],
    "workflowInstanceIds": [
        "88ce68d00e824c78a53af04f16d276ea"
    ]
}

请注意，JSON 结构与提交计划时完全相同。唯一不同的是请求被发送到 /alterations/run 端点，而不是 /alteration/submit 端点。

响应将包含执行结果：

{
  "results": [
    {
      "workflowInstanceId": "88ce68d00e824c78a53af04f16d276ea",
      "log": {
        "logEntries": [
          {
            "message": "ModifyVariable succeeded",
            "logLevel": 2,
            "timestamp": "2023-10-05T12:35:23.197167+00:00"
          },
          {
            "message": "Migrate succeeded",
            "logLevel": 2,
            "timestamp": "2023-10-05T12:35:23.202805+00:00"
          },
          {
            "message": "ScheduleActivity succeeded",
            "logLevel": 2,
            "timestamp": "2023-10-05T12:35:23.205629+00:00"
          }
        ]
      },
      "isSuccessful": true
    }
  ]
}
