使用Account Kit拉起华为账号登录的方法

private loginWithCallBack(): void {
    hilog.info(0x0000, 'testTag', 'loginWithCallBack');
    // 创建登录请求，并设置参数
    let loginRequest: authentication.LoginWithHuaweiIDRequest = new authentication.HuaweiIDProvider().createLoginWithHuaweiIDRequest();
    // 当用户未登录华为账号时，是否强制拉起华为账号登录界面
    loginRequest.forceLogin = true;
    // 用于防跨站点请求伪造，推荐采用如下方式给state赋值
    loginRequest.state = util.generateRandomUUID();

    // 执行登录请求
    try {
      let controller: authentication.AuthenticationController = new authentication.AuthenticationController(getContext(this));
      controller.executeRequest(loginRequest).then((data: authentication.AuthenticationResponse) => {
        let loginWithHuaweiIDResponse = data as authentication.LoginWithHuaweiIDResponse;
        let state: string = loginWithHuaweiIDResponse.state!;
        if (loginRequest.state != state) {
          hilog.error(0x0000, 'testTag', 'Failed to login. The state is different.');
          this.result = 'login false: The state is different.';
          return;
        }

        // 获取code后需要将code传给应用服务器，调用华为账号服务器接口换取Access Token，然后再获取用户其他信息。
