Question

我正在使用无节点节点和python在AWS上部署服务。使用的服务：S3，API网关，Cloudformation，Lambda。

问题是...我的响应正文为空：

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

字段“ body”为空。用POSTMAN测试时是相同的。但是当我在lambda上进行测试时，效果很好：

{
  "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：

如果您已从API Gateway异步调用了lambda函数，则通常会收到一个空响应，因为在这种情况下，API Gateway不会等待lambda响应并仅返回一个空响应。但是，您可以根据状态代码从API网关创建自己的集成响应模板。

如果您已同步调用但仍未收到响应，则还可以从API网关调用lambda函数，并观察lambda函数是否正常工作。
