No way to retrieve JSON response as is

[Sunix99]

In many case I need the JSON response AS IS (without marshaling).

A simple way to achieve this is to add an access to webresponse in IAmazonWebServiceResponse of unit AWS.Runtime.Model

IAmazonWebServiceResponse = interface
   ...
    function GetWebResponse: IWebResponseData;
    property WebResponse: IWebResponseData read GetWebResponse;
  end;

Then Implement it in TAmazonWebServiceResponse

function TAmazonWebServiceResponse.GetWebResponse: IWebResponseData;
begin
  Result := FWebResponse;
end;

It's in theory not safe for the SDK to make such low level data available from the class. There are a gazillion of processing going on, including on the response stream, which also handles, sometimes, unidirectional strings.

If you just want to log the raw response, you can use this:

uses AWS.Lib.Logging;
..

  TAWSConfigs.LoggingConfig.LogResponses := TResponseLoggingOption.Always;
  TAWSConfigs.LoggingConfig.LogResponsesSizeLimit := 1000;
  RegisterDebugLogger;

And you will have the raw responses logged to the Delphi debug output window.
We have fixed a bug regarding such logging so you will have to pull latest requests.
