TynSerial圖片序列(還原)

TynSerial圖片序列(還原)url

筆者以生成圖形驗證碼爲例。code

function TForm1.VerifyCode(image: TImage): string;
// 生成驗證碼和圖像
var
  url: SockString;
  serial: TynSerial;
  i: Integer;
  ms: TMemoryStream;
begin
  serial := TynSerial.Create;
  ms := TMemoryStream.Create;
  try
    url := 'verifycode';
    i := FHttp.Post(url, '', FDataType);
    if i = 200 then
    begin
      serial.Text := FHttp.Content;
      Result := serial.ReadString('code');
      serial.ReadStream('image', ms);
      ms.Position := 0;
      image.Picture.Bitmap.LoadFromStream(ms);
    end
    else
      ShowMessage(IntToStr(i) + ' error');
  finally
    serial.Free;
    ms.Free;
  end;
end;
