我一直在尝试使用最新的AWS SDK for PHP(7.4.2(创建MediaConverter作业，但我真的很难正确创建作业设置。我想知道是否有人可以看看这段php代码，告诉我我是否完全走错了方向。我得到的回应是：
在上执行"CreateJob"时出错https://asdf.mediaconvert.us-east-1.amazonaws.com/2017-08-29/jobs"；AWS HTTP错误：客户端错误：
POST https://asdf.mediaconvert.us-east-1.amazonaws.com/2017-08-29/jobs导致400 Bad Request响应：｛"errorType"："BadRequestException"，"httpStatus"：400，"requestId"："388473f1-92af-4253-940c-00307b7c2a79"，(截断…(BadRequestException(客户端(：无法解释请求。-｛"errorType"：无法解释该请求。"，"settingsValidationErrorsJsonBlob"："｝
我实际上直接从MediaConvert中复制了设置的JSON，所以我认为我的问题在于试图将其转换为PHP中的对象，以便将其发送到AWS。下面的设置可以通过AWS SDK到达服务器，我认为这是一个很好的开始。但我搞不清楚出了什么问题。

我解决了这个问题。
我从MediaConvert获得了JSON，然后分五个步骤创建了我的PHP：
- 用
array(替换所有{ - 将所有
:替换为=> - 将所有
[替换为array( - 将所有
}替换为) - 将所有
]替换为)
做完这件事后，第一次就完美地工作了。
