Amazon API Gateway:通过Postman调用API时，响应主体是否未转换? [英] Amazon API Gateway : response body is not transformed when the API is called via Postman?

问题描述

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:

When executing a testvia the AWS API Gateway console, I see that the output response from the Lambda function is correctly transformed:

{
  "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:

However when calling the API via Postman with headers:

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

没有进行任何输出转换，并且输出JSON消息仅为:

No output transformation is happening, and the output JSON message is just:

{
  "errorMessage": "501stef"
}

部分与> Amazon APi网关失败有关请求，但这是关于请求的问题.

Partly related to Amazon APi gateway fails to generate transformed request but this one talks about the Request.

推荐答案

在外部看到更改之前，您需要部署API ！

Before the changes are externally visible, you need to Deploy the API !
