Step Functions - 如何将完整的输入从一个阶段传递到下一个阶段？

Question

在我的一个状态机中，我有一个阶段从其前一阶段获取以下输入：

{
  "name": "put_book",
  "input": {
    "flight_timestamp": "1671872521",
    "flight_from": "GRU",
    "flight_to": "BER",
    "customer_id": "mike@dunder-mifflin.com",
    "passenger_lastname": "Scott",
    "passenger_firstname": "Michael",
    "TaskResult": {
      "Output": {
        "booking_id": "8aa96d88-2a0b-7777-9999-94f3edb46b6c"
      }
    }
  },
  "inputDetails": {
    "truncated": false
  }
}

我想将 booking_id 值传递给下一阶段，但输出如下所示：

{
  "name": "Parallel",
  "input": {
    "flight_timestamp": "1671872521",
    "flight_from": "GRU",
    "flight_to": "BER",
    "customer_id": "mike@dunder-mifflin.com",
    "passenger_lastname": "Scott",
    "passenger_firstname": "Michael",
    "TaskResult": {
      ... Execution information...
  "inputDetails": {
    "truncated": false
  }
}

我的 put_book 舞台是这样的：

"put_book": {
      "Type": "Task",
      "Resource": "arn:aws:states:::dynamodb:putItem",
      "Parameters": {
        "TableName": "TABLE",
        "Item": {...}
      },
      "InputPath": "$",
      "ResultPath": "$.TaskResult",
      "OutputPath": "$",
      "Next": "Parallel"
    },

我尝试通过数据流模拟器模拟它，它成功了！

如何在我的状态机中也传递 booking_id 转发？

谢谢！

Answer 1

"ResultPath": "$.TaskResult"

通过替换之前的结果导致“问题”
