json - Amazon API Gateway : response body is not transformed when the API is called via Postman?

Question

通过AWS API Gateway控制台执行测试时，我看到Lambda函数的输出响应已正确转换:

{
  "type" : "",
  "message" : "",
  "request-id" : ""
}

请参阅以下日志:

Tue Sep 06 14:46:06 UTC 2016 : Endpoint request body after transformations: {}
Tue Sep 06 14:46:06 UTC 2016 : Endpoint response body before transformations: {"errorMessage":"501stef"}
Tue Sep 06 14:46:06 UTC 2016 : Endpoint response headers: {x-amzn-Remapped-Content-Length=0, x-amzn-RequestId=a4540f42-7440-11e6-90ce-214b29fcde38, Connection=keep-alive, Content-Length=26, Date=Tue, 06 Sep 2016 14:46:06 GMT, Content-Type=application/json}
Tue Sep 06 14:46:06 UTC 2016 : Method response body after transformations: {
  "type" : "",
  "message" : "",
  "request-id" : ""
}
Tue Sep 06 14:46:06 UTC 2016 : Method response headers: {Content-Type=application/json}
Tue Sep 06 14:46:06 UTC 2016 : Successfully completed execution
Tue Sep 06 14:46:06 UTC 2016 : Method completed with status: 501

但是，通过带有标题的Postman调用API时:

Content-Type : application/json
Accept : application/json

没有输出转换发生，并且输出JSON消息只是:

{
  "errorMessage": "501stef"
}

与Amazon APi gateway fails to generate transformed request部分相关，但是这一部分讨论了请求。

在外部看不到更改之前，您需要部署API !
