AWS Step functions remove payload attribute from lambda output
问题
我有一个产生JSON对象数组的Lambda函数。我想将Lambda的结果传递给步骤函数，并将其放在给定的属性名称下。
运行Lambda的任务的输入:
{
"foo": "abc",
"bar": "def"
}
我想要的输出:
{
"foo": "abc",
"bar": "def",
"lambdaOutput": [
{...},
{...}
]
}
我认为ResultSelector + ResultPath应该能解决这个问题，但我卡住了。我尝试过以下内容：
"ResultSelector": {
"lambdaOutput.$": "$.Payload",
},
"ResultPath": "$.lambdaOutput"
但这只会创建一个嵌套的结构：
{
"foo": "abc",
"bar": "def",
"lambdaOutput":
"lambdaOutput: {
[
{...},
{...}
]
}
}
我漏掉了什么？
英文:
I have a lambda that produces an array of json objects. I want the lambda result passed to a step function under a given attribute name.
Input to task that runs lambda:
{
"foo": "abc",
"bar": "def"
}
Output I want
{
"foo": "abc",
"bar": "def",
"lambdaOutput": [
{...},
{...}
]
}
I thought ResultSelector + ResultPath is supposed to solve this problem but I am stuck. I tried
"ResultSelector": {
"lambdaOutput.$": "$.Payload",
},
"ResultPath": "$.lambdaOutput"
But this just creates a nested structure
{
"foo": "abc",
"bar": "def",
"lambdaOutput":
"lambdaOutput: {
[
{...},
{...}
]
}
}
What am i missing?

免责声明：我不是亚马逊状态语言专家，但尝试只使用以下代码：
{
"ResultPath": "$.lambdaOutput"
}

你可以从 CDK 中指定 payloadResponseOnly，但不确定如何从控制台执行此操作。
链接：https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions_tasks.LambdaInvoke.html#payloadresponseonly
英文:
Not sure how to do it from console, but from CDK, you can specify payloadResponseOnly
