Clear All Request Headers on a REST Object

See more REST Examples

Demonstrates Rest.ClearAllHeaders, which removes every request header previously added to the object.

var
success: Boolean;
rest: HCkRest;
bTls: Boolean;
bAutoReconnect: Boolean;

begin
success := False;

rest := CkRest_Create();

//  Connect to the REST server.  The 3rd argument enables TLS (use 1 for HTTPS on port 443),
//  and the 4th enables automatic reconnection if the connection is dropped between requests.
bTls := True;
bAutoReconnect := True;
success := CkRest_Connect(rest,'example.com',443,bTls,bAutoReconnect);
if (success = False) then
  begin
    Memo1.Lines.Add(CkRest__lastErrorText(rest));
    Exit;
  end;

CkRest_AddHeader(rest,'Accept','application/json');
CkRest_AddHeader(rest,'X-Custom-Header','example-value');

//  Remove all request headers previously added to this object, for example before reusing the same
//  Rest object for a different request.
CkRest_ClearAllHeaders(rest);

Memo1.Lines.Add('All request headers cleared.');

CkRest_Dispose(rest);
