Delphi DLL Requires Chilkat v11.0.0+

Transition from Http.GetHead to Http.HttpNoBody

Provides instructions for replacing deprecated GetHead method calls with HttpNoBody. Delphi DLL

var
success: Boolean;
http: HCkHttp;
url: PWideChar;
resp1: HCkHttpResponse;
resp2: HCkHttpResponse;

begin
success := False;

http := CkHttp_Create();
url := 'https://www.example.com/';

//  ------------------------------------------------------------------------
//  The GetHead method is deprecated:

resp1 := CkHttp_GetHead(http,url);
if (CkHttp_getLastMethodSuccess(http) = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;
Memo1.Lines.Add(IntToStr(CkHttpResponse_getStatusCode(resp1)));
CkHttpResponse_Dispose(resp1);

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

resp2 := CkHttpResponse_Create();
success := CkHttp_HttpNoBody(http,'HEAD',url,resp2);
if (success = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;
Memo1.Lines.Add(IntToStr(CkHttpResponse_getStatusCode(resp2)));

CkHttp_Dispose(http);
CkHttpResponse_Dispose(resp2);
