'AWS CDK - StepFunction - CallAwsService' 的 BatchGetBuilds 参数的正确格式是什么

Question

我正在为 CDK 的状态机工作。
并在状态机中检查代码构建项目状态时遇到问题...

问。你能告诉我 CallAwsService 中 batchGetBuilds 参数的正确格式吗？

import { CallAwsService } from "aws-cdk-lib/aws-stepfunctions-tasks"
import { JsonPath } from "aws-cdk-lib/aws-stepfunctions"

new CallAwsService(scope, "Check 1-1: Codebuild Status", {
        service: "codebuild",
        action: "batchGetBuilds",
        parameters: {
            Ids: [JsonPath.stringAt("$.results.codebuild.id")],
        },
        iamResources: ["*"],
        inputPath: "$",
        resultSelector: { "status.$": "$.builds[0].buildStatus" },
        resultPath: "$.results.bulidAmi",
    })

我尝试了两种方法。

JsonPath.stringAt("$.results.codebuild.id")
然后下面returns执行失败。

"An error occurred while executing the state 'Check 1-1: Codebuild Status' (entered at the event id #9). 
The Parameters '{\"Ids\":\"******-generate-new-ami-project:05763ec2-89a6-4b56-8b44-************\"}' could not be used to start the Task:
[Cannot deserialize instance of `java.util.ArrayList<java.lang.Object>` out of VALUE_STRING token]"

[JsonPath.stringAt("$.results.codebuild.id")]
如果我使用数组，它在构建阶段失败了...（我正在使用 cdk 管道来部署它）
下面是错误消息

Cannot use JsonPath fields in an array, they must be used in objects

+ 额外问题
我在搜索中找到了这个

我可以在 `CallAwsService` 上使用这个 `sync` 吗？（主要 1... 状态也在使用 `CallAwsService`）
如果是，我该如何使用它..?
或者我是否需要将 `CallAwsService` 更改为 `CodeBuildStartBuild`？

Could you let me know the correct format of batchGetBuilds parameters in CallAwsService?

使用States.Arrayintrinsic function。这些 CDK 语法是等价的：

parameters = {
  'Ids.$': 'States.Array($.results.codebuild.id)',
  Ids: JsonPath.stringAt('States.Array($.results.codebuild.id)'),
  Ids: JsonPath.array(JsonPath.stringAt('$.results.codebuild.id'))
}

Can I use this sync on the CallAwsService?

没有。 CallAwsService 任务为上下文实现 AWS SDK service integrations, which does not support .sync for CodeBuild actions. As of v2.15, CDK should throw an error if you pass the RUN_JOB (= .sync) pattern to CallAwsService. See this github issue。

Or do I need to change the CallAwsService to CodeBuildStartBuild?

是的。 CodeBuildStartBuild 与 RUN_JOB 集成模式一起正常工作。
