AWS CDK - Can I Pass LambdaInvoke's InputPath Prop Multiple JSON Paths?
问题
我发现new LambdaInvoke要求inputPath必须是一个字符串，所以无论我是否需要从多个地方传递event对象，我都需要一个Pass状态来实现它。
this.organiseTheArrayAndId = new Pass(this, "组织数组和ID在一个对象中", {
parameters: {
"array": JsonPath.stringAt("$.productIdsArray"),
"value": JsonPath.numberAt("$.productId.id")
},
resultPath: "$.organiseTheArrayAndId",
});
this.augmentProductIdArray = new LambdaInvoke(this, "将产品ID添加到数组中", {
lambdaFunction: lambdaFunctionLocation,
inputPath: "$.organiseTheArrayAndId",
});
英文:
I find new LambdaInvoke requires the inputPath to be a string, so whether I need to pass the event an object from multiple places, I need a Pass state to make it happen.
this.organiseTheArrayAndId = new Pass(this, "Organise the Array and Id Together In One Object", {
parameters: {
"array": JsonPath.stringAt("$.productIdsArray"),
"value": JsonPath.numberAt("$.productId.id")
},
resultPath: "$.organiseTheArrayAndId",
});
this.augmentProductIdArray = new LambdaInvoke(this, "Add the Product ID To The Array", {
lambdaFunction: lambdaFunctionLocation,
inputPath: "$.organiseTheArrayAndId",
});
Is there a more efficient way?

LambdaInvoke任务构造的payload属性允许您在调用函数时自定义函数接收的输入:
payload: sfn.TaskInput.fromObject({
array: JsonPath.stringAt("$.productIdsArray"),
value: JsonPath.numberAt("$.productId.id")
}),
英文:
The LambdaInvoke task construct's payload property lets you customize the input your function receives when invoked:
payload: sfn.TaskInput.fromObject({
array: JsonPath.stringAt("$.productIdsArray"),
value: JsonPath.numberAt("$.productId.id")
}),
