C# 在凭据提供程序中提交登录

我读了这篇文章来开发我的自定义凭证提供程序

现在我想测试中文章附带的代码

• 我跑 安装.reg文件

• 通过更改场景运行代码并在登录屏幕中显示GUI

   private static bool IsSupportedScenario(_CREDENTIAL_PROVIDER_USAGE_SCENARIO cpus)
  
       {
  
         switch (cpus)
          {
  
           case _CREDENTIAL_PROVIDER_USAGE_SCENARIO.CPUS_CREDUI:
              return true;
  
          case _CREDENTIAL_PROVIDER_USAGE_SCENARIO.CPUS_UNLOCK_WORKSTATION:
              return true;
  
          case _CREDENTIAL_PROVIDER_USAGE_SCENARIO.CPUS_LOGON:
              return true;
          case _CREDENTIAL_PROVIDER_USAGE_SCENARIO.CPUS_CHANGE_PASSWORD:
          case _CREDENTIAL_PROVIDER_USAGE_SCENARIO.CPUS_PLAP:
          case _CREDENTIAL_PROVIDER_USAGE_SCENARIO.CPUS_INVALID:
          default:
              return false;
      }
  }

问题是，如果正确，我如何提交插入的用户名/密码并成功登录？

您是否正在搜索此示例：？

我使用此示例。如问题中所述更改使用场景，并在此函数中输入用户名/密码

public int GetSerialization(out _CREDENTIAL_PROVIDER_GET_SERIALIZATION_RESPONSE pcpgsr,
            out _CREDENTIAL_PROVIDER_CREDENTIAL_SERIALIZATION pcpcs, out string ppszOptionalStatusText,
            out _CREDENTIAL_PROVIDER_STATUS_ICON pcpsiOptionalStatusIcon)
        {
            Log.LogMethodCall();

            try
            {
                pcpgsr = _CREDENTIAL_PROVIDER_GET_SERIALIZATION_RESPONSE.CPGSR_RETURN_CREDENTIAL_FINISHED;
                pcpcs = new _CREDENTIAL_PROVIDER_CREDENTIAL_SERIALIZATION();

                var username = "Domain\\username";
                var password = "password";
                var inCredSize = 0;
                var inCredBuffer = Marshal.AllocCoTaskMem(0);

                if (!PInvoke.CredPackAuthenticationBuffer(0, username, password, inCredBuffer, ref inCredSize))
                {
                    Marshal.FreeCoTaskMem(inCredBuffer);
                    inCredBuffer = Marshal.AllocCoTaskMem(inCredSize);

                    if (PInvoke.CredPackAuthenticationBuffer(0, username, password, inCredBuffer, ref inCredSize))
                    {
                        ppszOptionalStatusText = string.Empty;
                        pcpsiOptionalStatusIcon = _CREDENTIAL_PROVIDER_STATUS_ICON.CPSI_SUCCESS;

                        pcpcs.clsidCredentialProvider = Guid.Parse(Constants.CredentialProviderUID);
                        pcpcs.rgbSerialization = inCredBuffer;
                        pcpcs.cbSerialization = (uint)inCredSize;

                        RetrieveNegotiateAuthPackage(out var authPackage);
                        pcpcs.ulAuthenticationPackage = authPackage;

                        return HResultValues.S_OK;
                    }

                    ppszOptionalStatusText = "Failed to pack credentials";
                    pcpsiOptionalStatusIcon = _CREDENTIAL_PROVIDER_STATUS_ICON.CPSI_ERROR;
                    return HResultValues.E_FAIL;
                }
            }
            catch (Exception)
            {
                // In case of any error, do not bring down winlogon
            }
            finally
            {
                shouldAutoLogin = false; // Block auto-login from being stupid
            }

            pcpgsr = _CREDENTIAL_PROVIDER_GET_SERIALIZATION_RESPONSE.CPGSR_NO_CREDENTIAL_NOT_FINISHED;
            pcpcs = new _CREDENTIAL_PROVIDER_CREDENTIAL_SERIALIZATION();
            ppszOptionalStatusText = string.Empty;
            pcpsiOptionalStatusIcon = _CREDENTIAL_PROVIDER_STATUS_ICON.CPSI_NONE;
            return HResultValues.E_NOTIMPL;
        }

最后，我可以测试.net自定义凭据提供程序。

这也让我挂断了一段时间。但这只是我对凭证提供者如何工作以及如何实现其接口的误解

实际上，您并不是自己“提交”凭证。您只需通过填充_-CREDENTIAL\u-PROVIDER\u-CREDENTIAL\u-SERIALIZATION将它们序列化，如上面接受的答案所示，Windows负责将它们实际提交到Winlogon.exe

然后可以在ReportResult（）方法中检查提交文件的结果
