需要帮助在 php 中为 AWS MediaConvert 创建作业设置

Question

我一直在尝试使用最新的适用于 PHP 的 AWS 开发工具包 (7.4.2) 创建 MediaConverter 作业，但我真的无法正确创建作业设置。 我想知道是否有人可以查看此 php 代码并告诉我我是否完全走错了路。 我得到的回应是：

在“ https://asdf.mediaconvert.us-east-1.amazonaws.com/2017-08-29/jobs ”上执行“CreateJob”时出错； 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 (client): 请求无法解释。 - { "errorType": "BadRequestException", "httpStatus" : 400, "requestId" : "388473f1-92af-4253-940c-00307b7c2a79", "message" : "请求无法被解释。", "settingsValidationErrorsJsonBlob" "" }

我实际上直接从 MediaConvert 复制了设置的 JSON，所以我认为我的问题在于尝试将其转换为 PHP 中的对象，以便将其发送到 AWS。 下面的设置通过 AWS 开发工具包到达服务器，我认为这是一个好的开始。 但我无法弄清楚出了什么问题。

Answer 1

我解决了这个问题。

我使用了从 MediaConvert 获得的 JSON，然后通过五个步骤创建了我的 PHP：

1. 更换所有{与array(
2. 全部替换:用=>
3. 将所有[替换为array(
4. 将所有}替换为)
5. 将所有]替换为)

这样做之后，它第一次完美运行。
