我正在使用节点无服务器和 python 在 AWS 上部署服务。使用的服务：S3、API-Gateway、Cloudformation、Lambda。

问题是......我得到了空的响应体：

{
  "statusCode": 200,
  "isBase64Encoded": false,
  "headers": {
    "Content-Type": "application/json"
  },
  "body": "{}"
}

字段“body”是空的。当我用 POSTMAN 测试时也是如此。但是当我在 lambda 上测试时它工作正常：

{
  "statusCode": 200,
  "isBase64Encoded": false,
  "headers": {
    "Content-Type": "application/json"
  },
  "body": "{\"55b7badc-75af-41c0-9877-af308264cb33\":\"0.4666666666666667\",\"4694e172-322e-4a51-930e-d3b9bfd3c2e6\":\"0.36363636363636365\",\"c5447cc5-936d-4aa6-97c4-3f51a7e7c283\":\"0.3\",\"6abf0893-5d32-4a43-942f-aaef4395d91d\":\"0.2727272727272727\",\"c0bf1214-fb41-48eb-b07d-f81b71ba0061\":\"0.25\"}"
}

这是 yml 文件：
