Delphi ActiveX Requires Chilkat v11.0.0+

Transition from Http.PostUrlEncoded to Http.HttpReq

Provides instructions for replacing deprecated PostUrlEncoded method calls with HttpReq.

Sends the following raw HTTP request:

POST /echoPost.asp HTTP/1.1
Host: www.chilkatsoft.com
Content-Type: application/x-www-form-urlencoded
Content-Length: 50

company=example&ip=111.111.111.111&url=example.com

success: Integer;
http: TChilkatHttp;
url: WideString;
req: TChilkatHttpRequest;
responseObj: IChilkatHttpResponse;
req2: TChilkatHttpRequest;
resp: TChilkatHttpResponse;

//  ------------------------------------------------------------------------
//  The PostUrlEncoded method is deprecated:

responseObj := http.PostUrlEncoded(url,req.ControlInterface);
if (http.LastMethodSuccess = 0) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

//  ...
//  ...

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

req2 := TChilkatHttpRequest.Create(Self);
req2.AddParam('company','example');
req2.AddParam('ip','111.111.111.111');
req2.AddParam('url','example.com');

req2.HttpVerb := 'POST';
req2.ContentType := 'application/x-www-form-urlencoded';

resp := TChilkatHttpResponse.Create(Self);
success := http.HttpReq(url,req2.ControlInterface,resp.ControlInterface);
if (success = 0) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

//  Results are contained in the HTTP response object...
