我目前正在构建一个 API，允许用户以编程方式在他们的亚马逊卖家账户中列出产品。我已经能够实现 OAuth 流程、进行 API 调用的签名机制，并且已经完成了提要 API 用例指南中提供的推荐步骤。最后一步是审查提要 API 处理和报告，这是我处于死胡同的地方。解密和解压缩响应后，我得到一个如下所示的 JSON 有效负载。但是，我无法理解错误，以及如何根据显示的错误代码和消息进行纠正：

{

    "sellerId": "A1HGLY0OQBKE5U",
    "version": "2.0",
    "feedId": "50021018827"
  },

    },

    }

    "warnings": 0,

}

最初上传的 json 有效负载基于此处JSON_LISTINGS_FEED提供的提要类型架构

加密前的确切有效载荷如下所示：

{
  "header": {
    "sellerId": "A1HGLY0OQBKE5U",
    "version": "2.0"
  },
  "messages": [
    {
      "messageId": 1,
      "operationType": "UPDATE",
      "sku": "sk129"
    },
    {
      "messageId": 2,
      "operationType": "UPDATE",
      "sku": "sk1005"
    },
    {
      "messageId": 3,
      "operationType": "UPDATE",
      "sku": "sk131"
    },
    {
      "messageId": 4,
      "operationType": "UPDATE",
      "sku": "sk132"
    },
    {
      "messageId": 5,
      "operationType": "UPDATE",
      "sku": "sk133"
    },
    {
      "messageId": 6,
      "operationType": "UPDATE",
      "sku": "sk134"
    },
    {
      "messageId": 7,
      "operationType": "UPDATE",
      "sku": "sk135"
    },
    {
      "messageId": 8,
      "operationType": "UPDATE",
      "sku": "sk136"
    },
    {
      "messageId": 9,

    },
    {
      "messageId": 10,
      "operationType": "UPDATE",
      "sku": "sk138"
    }
  ]
}

终于发现了错误。使用在线 JSON 模式验证器工具。并针对此架构对其进行验证并相应地调整您的有效负载。
