Provides instructions for replacing deprecated PostJson method calls with HttpStr. Delphi DLL

var
success: Boolean;
http: HCkHttp;
url: PWideChar;
jsonText: PWideChar;
responseObj: HCkHttpResponse;
responseOut: HCkHttpResponse;

begin
success := False;

http := CkHttp_Create();

url := 'https://example.com/something';
jsonText := '{ ... }';

//  ------------------------------------------------------------------------
//  The PostJson method is deprecated:

responseObj := CkHttp_PostJson(http,url,jsonText);
if (CkHttp_getLastMethodSuccess(http) = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;

//  ...
//  ...

CkHttpResponse_Dispose(responseObj);

//  ------------------------------------------------------------------------
//  Do the equivalent using HttpStr.
//  Your application creates a new, empty HttpResponse object which is passed 
//  in the last argument and filled upon success.

responseOut := CkHttpResponse_Create();
success := CkHttp_HttpStr(http,'POST',url,jsonText,'utf-8','application/json',responseOut);
if (success = False) then
  begin
