• • 使用案例：**

1.Map阶跃函数1中的子项
1.将每个JSON对象发送到步骤函数2
1.在步骤功能2结束时，它接收来自第三方API的响应
1.在阶跃函数1中使用该API响应

• • 代码：**

this.mapOverChildren = new Map(this, "Map Over Children", {
  itemsPath: "$.data.children",
  maxConcurrency: 1,
  resultPath: "$.children",
});

this.mapOverChildren .iterator(new StepFunctionsStartExecution(this, 'Send Data to Step Function 2', {
  stateMachine: stepFunction.Two,
  integrationPattern: IntegrationPattern.REQUEST_RESPONSE,
  resultPath: "$.stepFunctionTwoResponse"
});

此时，resultPath仅显示有关阶跃函数执行的信息。如何从阶跃函数2取回数据？
