Add a Query Parameter to a REST Request

See more REST Examples

Demonstrates Rest.AddQueryParam, which adds or replaces a query-string parameter. The 1st argument is the parameter name and the 2nd is its value; Chilkat URL-encodes both as needed.

var
success: Integer;
rest: TChilkatRest;
bTls: Integer;
bAutoReconnect: Integer;
responseText: WideString;

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;

//  Add query-string parameters.  The 1st argument is the parameter name and the 2nd is its value.
//  Chilkat automatically URL-encodes names and values as needed.
rest.AddQueryParam('q','chilkat rest');
rest.AddQueryParam('limit','10');

//  For a GET request the parameters are appended to the URL query string.
responseText := rest.FullRequestNoBody('GET','/api/search');
if (rest.LastMethodSuccess = 0) then
  begin
    Memo1.Lines.Add(rest.LastErrorText);
    Exit;
  end;
Memo1.Lines.Add(responseText);
