Implementation

void addEventHandler({

  /// "gen_time":"1636015810","captcha_output":"1X_RK3ag_IKlW15iHhSywQ=="}, state: true}
  /// 失败结构示例:
  /// {response: {"captchaId":"647f5ed2ed8acb4be36784e01556bb71","captchaType":"slide",
  /// "challenge":"d04423f3-5297-44f5-bafa-cb868095c605"}, state: false}
  EventHandler? onResult,

  /// 错误回调
  /// 结构示例：{msg: 验证会话已取消, code: -14460, desc: {"description":"User cancelled 'Captcha'"}}
