将参数传递给下一个步骤函数任务。

Question

【以下的问题经过翻译处理】 ```
{
  "Comment": "A description of my state machine",
  "StartAt": "Batch SubmitJob",
  "States": {
    "Batch SubmitJob": {
      "Type": "Task",
      "Resource": "arn:aws:states:::batch:submitJob.sync",
      "Parameters": {
        "JobDefinition": "arn:aws:batch:us-east-1:XXXXXXXXXXX:job-definition/clientcopyjobdef:1",
        "JobQueue": "arn:aws:batch:us-east-1:XXXXXXXXXX:job-queue/copyclientjq",
        "ContainerOverrides": {
          "Command.$": [
            "dotnet",
            "CopyClientJob.dll",
            "$.input"
          ]
        },
        "JobName.$": "$.input"
      },
      "End": true
    }
  }
}
```
我试图创建这个状态机，如果直接将命令传递给JobDefinition，它可以正常工作，但是在这里我想要覆盖命令，并希望从状态输入中传递命令参数，因此尝试像上面的代码一样传递。对于 "JobName.$": "$. input" 它可以工作，但是对于

```
"Command.$": [
            "dotnet",
            "CopyClientJob.dll",
            "$.input"
          ]

```

它不起作用，命令被原样传递到aws batch而不是转换参数，有人可以帮忙吗。
谢谢

【以下的回答经过翻译处理】 获得了解决方案，实际上我需要像下面这样使用 `States.Array` 来合并所有 3 个部分：

```
{
  "Comment": "A description of my state machine",
  "StartAt": "Batch SubmitJob",
  "States": {
    "Batch SubmitJob": {
      "Type": "Task",
      "Resource": "arn:aws:states:::batch:submitJob.sync",
      "Parameters": {
        "JobDefinition": "arn:aws:batch:us-east-1:XXXXXXXXX:job-definition/clientcopyjobdef:1",
        "JobQueue": "arn:aws:batch:us-east-1:XXXXXXXX:job-queue/copyclientjq",
        "ContainerOverrides": {
          "Command.$": "States.Array('dotnet', 'CopyClientJob.dll', $.input)"
        },
        "JobName": "test"
      },
      "End": true
    }
  }
}

```
