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: Integer;
rest: TChilkatRest;
bTls: Integer;
bAutoReconnect: Integer;

begin
success := 0;

rest := TChilkatRest.Create(Self);

//  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 := 1;
bAutoReconnect := 1;
success := rest.Connect('example.com',443,bTls,bAutoReconnect);
if (success = 0) then
  begin
    Memo1.Lines.Add(rest.LastErrorText);
    Exit;
  end;

rest.AddHeader('Accept','application/json');
rest.AddHeader('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.
rest.ClearAllHeaders();

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