Delphi DLL Requires Chilkat v11.0.0+

Transition from Http.PostJson3 to Http.HttpJson

Provides instructions for replacing deprecated PostJson3 method calls with HttpJson. Delphi DLL

var
success: Boolean;
http: HCkHttp;
url: PWideChar;
contentType: PWideChar;
json: HCkJsonObject;
responseObj: HCkHttpResponse;
responseOut: HCkHttpResponse;

begin
success := False;

http := CkHttp_Create();

url := 'https://example.com/something';
contentType := 'application/json';
json := CkJsonObject_Create();
CkJsonObject_LoadFile(json,'C:/temp/requestBody.json');

//  ------------------------------------------------------------------------
//  The PostJson3 method is deprecated:

responseObj := CkHttp_PostJson3(http,url,contentType,json);
if (CkHttp_getLastMethodSuccess(http) = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;

//  ...
//  ...

CkHttpResponse_Dispose(responseObj);

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

responseOut := CkHttpResponse_Create();
success := CkHttp_HttpJson(http,'POST',url,json,contentType,responseOut);
if (success = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
